- Copyright (C) 1989, 1991 Free Software Foundation, Inc.
-     59 Temple Place, Suite 330, Boston, MA  02111-1307  USA
- Everyone is permitted to copy and distribute verbatim copies
- of this license document, but changing it is not allowed.
+1. You may make and give away verbatim copies of the source form of the
+   software without restriction, provided that you duplicate all of the
+   original copyright notices and associated disclaimers.
 
-			    Preamble
+2. You may modify your copy of the software in any way, provided that
+   you do at least ONE of the following:
 
-  The licenses for most software are designed to take away your
-freedom to share and change it.  By contrast, the GNU General Public
-License is intended to guarantee your freedom to share and change free
-software--to make sure the software is free for all its users.  This
-General Public License applies to most of the Free Software
-Foundation's software and to any other program whose authors commit to
-using it.  (Some other Free Software Foundation software is covered by
-the GNU Library General Public License instead.)  You can apply it to
-your programs, too.
+   a. place your modifications in the Public Domain or otherwise
+      make them Freely Available, such as by posting said
+      modifications to Usenet or an equivalent medium, or by allowing
+      the author to include your modifications in the software.
 
-  When we speak of free software, we are referring to freedom, not
-price.  Our General Public Licenses are designed to make sure that you
-have the freedom to distribute copies of free software (and charge for
-this service if you wish), that you receive source code or can get it
-if you want it, that you can change the software or use pieces of it
-in new free programs; and that you know you can do these things.
+   b. use the modified software only within your corporation or
+      organization.
 
-  To protect your rights, we need to make restrictions that forbid
-anyone to deny you these rights or to ask you to surrender the rights.
-These restrictions translate to certain responsibilities for you if you
-distribute copies of the software, or if you modify it.
+   c. give non-standard binaries non-standard names, with
+      instructions on where to get the original software distribution.
 
-  For example, if you distribute copies of such a program, whether
-gratis or for a fee, you must give the recipients all the rights that
-you have.  You must make sure that they, too, receive or can get the
-source code.  And you must show them these terms so they know their
-rights.
+   d. make other distribution arrangements with the author.
 
-  We protect your rights with two steps: (1) copyright the software, and
-(2) offer you this license which gives you legal permission to copy,
-distribute and/or modify the software.
+3. You may distribute the software in object code or binary form,
+   provided that you do at least ONE of the following:
 
-  Also, for each author's protection and ours, we want to make certain
-that everyone understands that there is no warranty for this free
-software.  If the software is modified by someone else and passed on, we
-want its recipients to know that what they have is not the original, so
-that any problems introduced by others will not reflect on the original
-authors' reputations.
+   a. distribute the binaries and library files of the software,
+      together with instructions (in the manual page or equivalent)
+      on where to get the original distribution.
 
-  Finally, any free program is threatened constantly by software
-patents.  We wish to avoid the danger that redistributors of a free
-program will individually obtain patent licenses, in effect making the
-program proprietary.  To prevent this, we have made it clear that any
-patent must be licensed for everyone's free use or not licensed at all.
+   b. accompany the distribution with the machine-readable source of
+      the software.
 
-  The precise terms and conditions for copying, distribution and
-modification follow.
-
-		    GNU GENERAL PUBLIC LICENSE
-   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+   c. give non-standard binaries non-standard names, with
+      instructions on where to get the original software distribution.
 
-  0. This License applies to any program or other work which contains
-a notice placed by the copyright holder saying it may be distributed
-under the terms of this General Public License.  The "Program", below,
-refers to any such program or work, and a "work based on the Program"
-means either the Program or any derivative work under copyright law:
-that is to say, a work containing the Program or a portion of it,
-either verbatim or with modifications and/or translated into another
-language.  (Hereinafter, translation is included without limitation in
-the term "modification".)  Each licensee is addressed as "you".
+   d. make other distribution arrangements with the author.
 
-Activities other than copying, distribution and modification are not
-covered by this License; they are outside its scope.  The act of
-running the Program is not restricted, and the output from the Program
-is covered only if its contents constitute a work based on the
-Program (independent of having been made by running the Program).
-Whether that is true depends on what the Program does.
+4. You may modify and include the part of the software into any other
+   software (possibly commercial).  But some files in the distribution
+   are not written by the author, so that they are not under these terms.
 
-  1. You may copy and distribute verbatim copies of the Program's
-source code as you receive it, in any medium, provided that you
-conspicuously and appropriately publish on each copy an appropriate
-copyright notice and disclaimer of warranty; keep intact all the
-notices that refer to this License and to the absence of any warranty;
-and give any other recipients of the Program a copy of this License
-along with the Program.
+   For the list of those files and their copying conditions, see the
+   file LEGAL.
 
-You may charge a fee for the physical act of transferring a copy, and
-you may at your option offer warranty protection in exchange for a fee.
+5. The scripts and library files supplied as input to or produced as
+   output from the software do not automatically fall under the
+   copyright of the software, but belong to whomever generated them,
+   and may be sold commercially, and may be aggregated with this
+   software.
 
-  2. You may modify your copy or copies of the Program or any portion
-of it, thus forming a work based on the Program, and copy and
-distribute such modifications or work under the terms of Section 1
-above, provided that you also meet all of these conditions:
-
-    a) You must cause the modified files to carry prominent notices
-    stating that you changed the files and the date of any change.
-
-    b) You must cause any work that you distribute or publish, that in
-    whole or in part contains or is derived from the Program or any
-    part thereof, to be licensed as a whole at no charge to all third
-    parties under the terms of this License.
-
-    c) If the modified program normally reads commands interactively
-    when run, you must cause it, when started running for such
-    interactive use in the most ordinary way, to print or display an
-    announcement including an appropriate copyright notice and a
-    notice that there is no warranty (or else, saying that you provide
-    a warranty) and that users may redistribute the program under
-    these conditions, and telling the user how to view a copy of this
-    License.  (Exception: if the Program itself is interactive but
-    does not normally print such an announcement, your work based on
-    the Program is not required to print an announcement.)
-
-These requirements apply to the modified work as a whole.  If
-identifiable sections of that work are not derived from the Program,
-and can be reasonably considered independent and separate works in
-themselves, then this License, and its terms, do not apply to those
-sections when you distribute them as separate works.  But when you
-distribute the same sections as part of a whole which is a work based
-on the Program, the distribution of the whole must be on the terms of
-this License, whose permissions for other licensees extend to the
-entire whole, and thus to each and every part regardless of who wrote it.
-
-Thus, it is not the intent of this section to claim rights or contest
-your rights to work written entirely by you; rather, the intent is to
-exercise the right to control the distribution of derivative or
-collective works based on the Program.
-
-In addition, mere aggregation of another work not based on the Program
-with the Program (or with a work based on the Program) on a volume of
-a storage or distribution medium does not bring the other work under
-the scope of this License.
-
-  3. You may copy and distribute the Program (or a work based on it,
-under Section 2) in object code or executable form under the terms of
-Sections 1 and 2 above provided that you also do one of the following:
-
-    a) Accompany it with the complete corresponding machine-readable
-    source code, which must be distributed under the terms of Sections
-    1 and 2 above on a medium customarily used for software interchange; or,
-
-    b) Accompany it with a written offer, valid for at least three
-    years, to give any third party, for a charge no more than your
-    cost of physically performing source distribution, a complete
-    machine-readable copy of the corresponding source code, to be
-    distributed under the terms of Sections 1 and 2 above on a medium
-    customarily used for software interchange; or,
-
-    c) Accompany it with the information you received as to the offer
-    to distribute corresponding source code.  (This alternative is
-    allowed only for noncommercial distribution and only if you
-    received the program in object code or executable form with such
-    an offer, in accord with Subsection b above.)
-
-The source code for a work means the preferred form of the work for
-making modifications to it.  For an executable work, complete source
-code means all the source code for all modules it contains, plus any
-associated interface definition files, plus the scripts used to
-control compilation and installation of the executable.  However, as a
-special exception, the source code distributed need not include
-anything that is normally distributed (in either source or binary
-form) with the major components (compiler, kernel, and so on) of the
-operating system on which the executable runs, unless that component
-itself accompanies the executable.
-
-If distribution of executable or object code is made by offering
-access to copy from a designated place, then offering equivalent
-access to copy the source code from the same place counts as
-distribution of the source code, even though third parties are not
-compelled to copy the source along with the object code.
-
-  4. You may not copy, modify, sublicense, or distribute the Program
-except as expressly provided under this License.  Any attempt
-otherwise to copy, modify, sublicense or distribute the Program is
-void, and will automatically terminate your rights under this License.
-However, parties who have received copies, or rights, from you under
-this License will not have their licenses terminated so long as such
-parties remain in full compliance.
-
-  5. You are not required to accept this License, since you have not
-signed it.  However, nothing else grants you permission to modify or
-distribute the Program or its derivative works.  These actions are
-prohibited by law if you do not accept this License.  Therefore, by
-modifying or distributing the Program (or any work based on the
-Program), you indicate your acceptance of this License to do so, and
-all its terms and conditions for copying, distributing or modifying
-the Program or works based on it.
-
-  6. Each time you redistribute the Program (or any work based on the
-Program), the recipient automatically receives a license from the
-original licensor to copy, distribute or modify the Program subject to
-these terms and conditions.  You may not impose any further
-restrictions on the recipients' exercise of the rights granted herein.
-You are not responsible for enforcing compliance by third parties to
-this License.
-
-  7. If, as a consequence of a court judgment or allegation of patent
-infringement or for any other reason (not limited to patent issues),
-conditions are imposed on you (whether by court order, agreement or
-otherwise) that contradict the conditions of this License, they do not
-excuse you from the conditions of this License.  If you cannot
-distribute so as to satisfy simultaneously your obligations under this
-License and any other pertinent obligations, then as a consequence you
-may not distribute the Program at all.  For example, if a patent
-license would not permit royalty-free redistribution of the Program by
-all those who receive copies directly or indirectly through you, then
-the only way you could satisfy both it and this License would be to
-refrain entirely from distribution of the Program.
-
-If any portion of this section is held invalid or unenforceable under
-any particular circumstance, the balance of the section is intended to
-apply and the section as a whole is intended to apply in other
-circumstances.
-
-It is not the purpose of this section to induce you to infringe any
-patents or other property right claims or to contest validity of any
-such claims; this section has the sole purpose of protecting the
-integrity of the free software distribution system, which is
-implemented by public license practices.  Many people have made
-generous contributions to the wide range of software distributed
-through that system in reliance on consistent application of that
-system; it is up to the author/donor to decide if he or she is willing
-to distribute software through any other system and a licensee cannot
-impose that choice.
-
-This section is intended to make thoroughly clear what is believed to
-be a consequence of the rest of this License.
-
-  8. If the distribution and/or use of the Program is restricted in
-certain countries either by patents or by copyrighted interfaces, the
-original copyright holder who places the Program under this License
-may add an explicit geographical distribution limitation excluding
-those countries, so that distribution is permitted only in or among
-countries not thus excluded.  In such case, this License incorporates
-the limitation as if written in the body of this License.
-
-  9. The Free Software Foundation may publish revised and/or new versions
-of the General Public License from time to time.  Such new versions will
-be similar in spirit to the present version, but may differ in detail to
-address new problems or concerns.
-
-Each version is given a distinguishing version number.  If the Program
-specifies a version number of this License which applies to it and "any
-later version", you have the option of following the terms and conditions
-either of that version or of any later version published by the Free
-Software Foundation.  If the Program does not specify a version number of
-this License, you may choose any version ever published by the Free Software
-Foundation.
-
-  10. If you wish to incorporate parts of the Program into other free
-programs whose distribution conditions are different, write to the author
-to ask for permission.  For software which is copyrighted by the Free
-Software Foundation, write to the Free Software Foundation; we sometimes
-make exceptions for this.  Our decision will be guided by the two goals
-of preserving the free status of all derivatives of our free software and
-of promoting the sharing and reuse of software generally.
-
-			    NO WARRANTY
-
-  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
-FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
-OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
-PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
-OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
-MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
-TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
-PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
-REPAIR OR CORRECTION.
-
-  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
-WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
-REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
-INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
-OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
-TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
-YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
-PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
-POSSIBILITY OF SUCH DAMAGES.
-
-		     END OF TERMS AND CONDITIONS
-
-	    How to Apply These Terms to Your New Programs
-
-  If you develop a new program, and you want it to be of the greatest
-possible use to the public, the best way to achieve this is to make it
-free software which everyone can redistribute and change under these terms.
-
-  To do so, attach the following notices to the program.  It is safest
-to attach them to the start of each source file to most effectively
-convey the exclusion of warranty; and each file should have at least
-the "copyright" line and a pointer to where the full notice is found.
-
-    <one line to give the program's name and a brief idea of what it does.>
-    Copyright (C) 19yy  <name of author>
-
-    This program is free software; you can redistribute it and/or modify
-    it under the terms of the GNU General Public License as published by
-    the Free Software Foundation; either version 2 of the License, or
-    (at your option) any later version.
-
-    This program is distributed in the hope that it will be useful,
-    but WITHOUT ANY WARRANTY; without even the implied warranty of
-    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
-    GNU General Public License for more details.
-
-    You should have received a copy of the GNU General Public License
-    along with this program; if not, write to the Free Software
-    Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA  02111-1307  USA
-
-
-Also add information on how to contact you by electronic and paper mail.
-
-If the program is interactive, make it output a short notice like this
-when it starts in an interactive mode:
-
-    Gnomovision version 69, Copyright (C) 19yy name of author
-    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
-    This is free software, and you are welcome to redistribute it
-    under certain conditions; type `show c' for details.
-
-The hypothetical commands `show w' and `show c' should show the appropriate
-parts of the General Public License.  Of course, the commands you use may
-be called something other than `show w' and `show c'; they could even be
-mouse-clicks or menu items--whatever suits your program.
-
-You should also get your employer (if you work as a programmer) or your
-school, if any, to sign a "copyright disclaimer" for the program, if
-necessary.  Here is a sample; alter the names:
-
-  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
-  `Gnomovision' (which makes passes at compilers) written by James Hacker.
-
-  <signature of Ty Coon>, 1 April 1989
-  Ty Coon, President of Vice
-
-This General Public License does not permit incorporating your program into
-proprietary programs.  If your program is a subroutine library, you may
-consider it more useful to permit linking proprietary applications with the
-library.  If this is what you want to do, use the GNU Library General
-Public License instead of this License.
+6. THIS SOFTWARE IS PROVIDED "AS IS" AND WITHOUT ANY EXPRESS OR
+   IMPLIED WARRANTIES, INCLUDING, WITHOUT LIMITATION, THE IMPLIED
+   WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+   PURPOSE.

-
- Copyright (C) 1991 Free Software Foundation, Inc.
-                    675 Mass Ave, Cambridge, MA 02139, USA
- Everyone is permitted to copy and distribute verbatim copies
- of this license document, but changing it is not allowed.
-
-[This is the first released version of the library GPL.  It is
- numbered 2 because it goes with version 2 of the ordinary GPL.]
-
-			    Preamble
-
-  The licenses for most software are designed to take away your
-freedom to share and change it.  By contrast, the GNU General Public
-Licenses are intended to guarantee your freedom to share and change
-free software--to make sure the software is free for all its users.
-
-  This license, the Library General Public License, applies to some
-specially designated Free Software Foundation software, and to any
-other libraries whose authors decide to use it.  You can use it for
-your libraries, too.
-
-  When we speak of free software, we are referring to freedom, not
-price.  Our General Public Licenses are designed to make sure that you
-have the freedom to distribute copies of free software (and charge for
-this service if you wish), that you receive source code or can get it
-if you want it, that you can change the software or use pieces of it
-in new free programs; and that you know you can do these things.
-
-  To protect your rights, we need to make restrictions that forbid
-anyone to deny you these rights or to ask you to surrender the rights.
-These restrictions translate to certain responsibilities for you if
-you distribute copies of the library, or if you modify it.
-
-  For example, if you distribute copies of the library, whether gratis
-or for a fee, you must give the recipients all the rights that we gave
-you.  You must make sure that they, too, receive or can get the source
-code.  If you link a program with the library, you must provide
-complete object files to the recipients so that they can relink them
-with the library, after making changes to the library and recompiling
-it.  And you must show them these terms so they know their rights.
-
-  Our method of protecting your rights has two steps: (1) copyright
-the library, and (2) offer you this license which gives you legal
-permission to copy, distribute and/or modify the library.
-
-  Also, for each distributor's protection, we want to make certain
-that everyone understands that there is no warranty for this free
-library.  If the library is modified by someone else and passed on, we
-want its recipients to know that what they have is not the original
-version, so that any problems introduced by others will not reflect on
-the original authors' reputations.
-
-  Finally, any free program is threatened constantly by software
-patents.  We wish to avoid the danger that companies distributing free
-software will individually obtain patent licenses, thus in effect
-transforming the program into proprietary software.  To prevent this,
-we have made it clear that any patent must be licensed for everyone's
-free use or not licensed at all.
-
-  Most GNU software, including some libraries, is covered by the ordinary
-GNU General Public License, which was designed for utility programs.  This
-license, the GNU Library General Public License, applies to certain
-designated libraries.  This license is quite different from the ordinary
-one; be sure to read it in full, and don't assume that anything in it is
-the same as in the ordinary license.
-
-  The reason we have a separate public license for some libraries is that
-they blur the distinction we usually make between modifying or adding to a
-program and simply using it.  Linking a program with a library, without
-changing the library, is in some sense simply using the library, and is
-analogous to running a utility program or application program.  However, in
-a textual and legal sense, the linked executable is a combined work, a
-derivative of the original library, and the ordinary General Public License
-treats it as such.
-
-  Because of this blurred distinction, using the ordinary General
-Public License for libraries did not effectively promote software
-sharing, because most developers did not use the libraries.  We
-concluded that weaker conditions might promote sharing better.
-
-  However, unrestricted linking of non-free programs would deprive the
-users of those programs of all benefit from the free status of the
-libraries themselves.  This Library General Public License is intended to
-permit developers of non-free programs to use free libraries, while
-preserving your freedom as a user of such programs to change the free
-libraries that are incorporated in them.  (We have not seen how to achieve
-this as regards changes in header files, but we have achieved it as regards
-changes in the actual functions of the Library.)  The hope is that this
-will lead to faster development of free libraries.
-
-  The precise terms and conditions for copying, distribution and
-modification follow.  Pay close attention to the difference between a
-"work based on the library" and a "work that uses the library".  The
-former contains code derived from the library, while the latter only
-works together with the library.
-
-  Note that it is possible for a library to be covered by the ordinary
-General Public License rather than by this special one.
-
-		  GNU LIBRARY GENERAL PUBLIC LICENSE
-   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
-
-  0. This License Agreement applies to any software library which
-contains a notice placed by the copyright holder or other authorized
-party saying it may be distributed under the terms of this Library
-General Public License (also called "this License").  Each licensee is
-addressed as "you".
-
-  A "library" means a collection of software functions and/or data
-prepared so as to be conveniently linked with application programs
-(which use some of those functions and data) to form executables.
-
-  The "Library", below, refers to any such software library or work
-which has been distributed under these terms.  A "work based on the
-Library" means either the Library or any derivative work under
-copyright law: that is to say, a work containing the Library or a
-portion of it, either verbatim or with modifications and/or translated
-straightforwardly into another language.  (Hereinafter, translation is
-included without limitation in the term "modification".)
-
-  "Source code" for a work means the preferred form of the work for
-making modifications to it.  For a library, complete source code means
-all the source code for all modules it contains, plus any associated
-interface definition files, plus the scripts used to control compilation
-and installation of the library.
-
-  Activities other than copying, distribution and modification are not
-covered by this License; they are outside its scope.  The act of
-running a program using the Library is not restricted, and output from
-such a program is covered only if its contents constitute a work based
-on the Library (independent of the use of the Library in a tool for
-writing it).  Whether that is true depends on what the Library does
-and what the program that uses the Library does.
-  
-  1. You may copy and distribute verbatim copies of the Library's
-complete source code as you receive it, in any medium, provided that
-you conspicuously and appropriately publish on each copy an
-appropriate copyright notice and disclaimer of warranty; keep intact
-all the notices that refer to this License and to the absence of any
-warranty; and distribute a copy of this License along with the
-Library.
-
-  You may charge a fee for the physical act of transferring a copy,
-and you may at your option offer warranty protection in exchange for a
-fee.
-
-  2. You may modify your copy or copies of the Library or any portion
-of it, thus forming a work based on the Library, and copy and
-distribute such modifications or work under the terms of Section 1
-above, provided that you also meet all of these conditions:
-
-    a) The modified work must itself be a software library.
-
-    b) You must cause the files modified to carry prominent notices
-    stating that you changed the files and the date of any change.
-
-    c) You must cause the whole of the work to be licensed at no
-    charge to all third parties under the terms of this License.
-
-    d) If a facility in the modified Library refers to a function or a
-    table of data to be supplied by an application program that uses
-    the facility, other than as an argument passed when the facility
-    is invoked, then you must make a good faith effort to ensure that,
-    in the event an application does not supply such function or
-    table, the facility still operates, and performs whatever part of
-    its purpose remains meaningful.
-
-    (For example, a function in a library to compute square roots has
-    a purpose that is entirely well-defined independent of the
-    application.  Therefore, Subsection 2d requires that any
-    application-supplied function or table used by this function must
-    be optional: if the application does not supply it, the square
-    root function must still compute square roots.)
-
-These requirements apply to the modified work as a whole.  If
-identifiable sections of that work are not derived from the Library,
-and can be reasonably considered independent and separate works in
-themselves, then this License, and its terms, do not apply to those
-sections when you distribute them as separate works.  But when you
-distribute the same sections as part of a whole which is a work based
-on the Library, the distribution of the whole must be on the terms of
-this License, whose permissions for other licensees extend to the
-entire whole, and thus to each and every part regardless of who wrote
-it.
-
-Thus, it is not the intent of this section to claim rights or contest
-your rights to work written entirely by you; rather, the intent is to
-exercise the right to control the distribution of derivative or
-collective works based on the Library.
-
-In addition, mere aggregation of another work not based on the Library
-with the Library (or with a work based on the Library) on a volume of
-a storage or distribution medium does not bring the other work under
-the scope of this License.
-
-  3. You may opt to apply the terms of the ordinary GNU General Public
-License instead of this License to a given copy of the Library.  To do
-this, you must alter all the notices that refer to this License, so
-that they refer to the ordinary GNU General Public License, version 2,
-instead of to this License.  (If a newer version than version 2 of the
-ordinary GNU General Public License has appeared, then you can specify
-that version instead if you wish.)  Do not make any other change in
-these notices.
-
-  Once this change is made in a given copy, it is irreversible for
-that copy, so the ordinary GNU General Public License applies to all
-subsequent copies and derivative works made from that copy.
-
-  This option is useful when you wish to copy part of the code of
-the Library into a program that is not a library.
-
-  4. You may copy and distribute the Library (or a portion or
-derivative of it, under Section 2) in object code or executable form
-under the terms of Sections 1 and 2 above provided that you accompany
-it with the complete corresponding machine-readable source code, which
-must be distributed under the terms of Sections 1 and 2 above on a
-medium customarily used for software interchange.
-
-  If distribution of object code is made by offering access to copy
-from a designated place, then offering equivalent access to copy the
-source code from the same place satisfies the requirement to
-distribute the source code, even though third parties are not
-compelled to copy the source along with the object code.
-
-  5. A program that contains no derivative of any portion of the
-Library, but is designed to work with the Library by being compiled or
-linked with it, is called a "work that uses the Library".  Such a
-work, in isolation, is not a derivative work of the Library, and
-therefore falls outside the scope of this License.
-
-  However, linking a "work that uses the Library" with the Library
-creates an executable that is a derivative of the Library (because it
-contains portions of the Library), rather than a "work that uses the
-library".  The executable is therefore covered by this License.
-Section 6 states terms for distribution of such executables.
-
-  When a "work that uses the Library" uses material from a header file
-that is part of the Library, the object code for the work may be a
-derivative work of the Library even though the source code is not.
-Whether this is true is especially significant if the work can be
-linked without the Library, or if the work is itself a library.  The
-threshold for this to be true is not precisely defined by law.
-
-  If such an object file uses only numerical parameters, data
-structure layouts and accessors, and small macros and small inline
-functions (ten lines or less in length), then the use of the object
-file is unrestricted, regardless of whether it is legally a derivative
-work.  (Executables containing this object code plus portions of the
-Library will still fall under Section 6.)
-
-  Otherwise, if the work is a derivative of the Library, you may
-distribute the object code for the work under the terms of Section 6.
-Any executables containing that work also fall under Section 6,
-whether or not they are linked directly with the Library itself.
-
-  6. As an exception to the Sections above, you may also compile or
-link a "work that uses the Library" with the Library to produce a
-work containing portions of the Library, and distribute that work
-under terms of your choice, provided that the terms permit
-modification of the work for the customer's own use and reverse
-engineering for debugging such modifications.
-
-  You must give prominent notice with each copy of the work that the
-Library is used in it and that the Library and its use are covered by
-this License.  You must supply a copy of this License.  If the work
-during execution displays copyright notices, you must include the
-copyright notice for the Library among them, as well as a reference
-directing the user to the copy of this License.  Also, you must do one
-of these things:
-
-    a) Accompany the work with the complete corresponding
-    machine-readable source code for the Library including whatever
-    changes were used in the work (which must be distributed under
-    Sections 1 and 2 above); and, if the work is an executable linked
-    with the Library, with the complete machine-readable "work that
-    uses the Library", as object code and/or source code, so that the
-    user can modify the Library and then relink to produce a modified
-    executable containing the modified Library.  (It is understood
-    that the user who changes the contents of definitions files in the
-    Library will not necessarily be able to recompile the application
-    to use the modified definitions.)
-
-    b) Accompany the work with a written offer, valid for at
-    least three years, to give the same user the materials
-    specified in Subsection 6a, above, for a charge no more
-    than the cost of performing this distribution.
-
-    c) If distribution of the work is made by offering access to copy
-    from a designated place, offer equivalent access to copy the above
-    specified materials from the same place.
-
-    d) Verify that the user has already received a copy of these
-    materials or that you have already sent this user a copy.
-
-  For an executable, the required form of the "work that uses the
-Library" must include any data and utility programs needed for
-reproducing the executable from it.  However, as a special exception,
-the source code distributed need not include anything that is normally
-distributed (in either source or binary form) with the major
-components (compiler, kernel, and so on) of the operating system on
-which the executable runs, unless that component itself accompanies
-the executable.
-
-  It may happen that this requirement contradicts the license
-restrictions of other proprietary libraries that do not normally
-accompany the operating system.  Such a contradiction means you cannot
-use both them and the Library together in an executable that you
-distribute.
-
-  7. You may place library facilities that are a work based on the
-Library side-by-side in a single library together with other library
-facilities not covered by this License, and distribute such a combined
-library, provided that the separate distribution of the work based on
-the Library and of the other library facilities is otherwise
-permitted, and provided that you do these two things:
-
-    a) Accompany the combined library with a copy of the same work
-    based on the Library, uncombined with any other library
-    facilities.  This must be distributed under the terms of the
-    Sections above.
-
-    b) Give prominent notice with the combined library of the fact
-    that part of it is a work based on the Library, and explaining
-    where to find the accompanying uncombined form of the same work.
-
-  8. You may not copy, modify, sublicense, link with, or distribute
-the Library except as expressly provided under this License.  Any
-attempt otherwise to copy, modify, sublicense, link with, or
-distribute the Library is void, and will automatically terminate your
-rights under this License.  However, parties who have received copies,
-or rights, from you under this License will not have their licenses
-terminated so long as such parties remain in full compliance.
-
-  9. You are not required to accept this License, since you have not
-signed it.  However, nothing else grants you permission to modify or
-distribute the Library or its derivative works.  These actions are
-prohibited by law if you do not accept this License.  Therefore, by
-modifying or distributing the Library (or any work based on the
-Library), you indicate your acceptance of this License to do so, and
-all its terms and conditions for copying, distributing or modifying
-the Library or works based on it.
-
-  10. Each time you redistribute the Library (or any work based on the
-Library), the recipient automatically receives a license from the
-original licensor to copy, distribute, link with or modify the Library
-subject to these terms and conditions.  You may not impose any further
-restrictions on the recipients' exercise of the rights granted herein.
-You are not responsible for enforcing compliance by third parties to
-this License.
-
-  11. If, as a consequence of a court judgment or allegation of patent
-infringement or for any other reason (not limited to patent issues),
-conditions are imposed on you (whether by court order, agreement or
-otherwise) that contradict the conditions of this License, they do not
-excuse you from the conditions of this License.  If you cannot
-distribute so as to satisfy simultaneously your obligations under this
-License and any other pertinent obligations, then as a consequence you
-may not distribute the Library at all.  For example, if a patent
-license would not permit royalty-free redistribution of the Library by
-all those who receive copies directly or indirectly through you, then
-the only way you could satisfy both it and this License would be to
-refrain entirely from distribution of the Library.
-
-If any portion of this section is held invalid or unenforceable under any
-particular circumstance, the balance of the section is intended to apply,
-and the section as a whole is intended to apply in other circumstances.
-
-It is not the purpose of this section to induce you to infringe any
-patents or other property right claims or to contest validity of any
-such claims; this section has the sole purpose of protecting the
-integrity of the free software distribution system which is
-implemented by public license practices.  Many people have made
-generous contributions to the wide range of software distributed
-through that system in reliance on consistent application of that
-system; it is up to the author/donor to decide if he or she is willing
-to distribute software through any other system and a licensee cannot
-impose that choice.
-
-This section is intended to make thoroughly clear what is believed to
-be a consequence of the rest of this License.
-
-  12. If the distribution and/or use of the Library is restricted in
-certain countries either by patents or by copyrighted interfaces, the
-original copyright holder who places the Library under this License may add
-an explicit geographical distribution limitation excluding those countries,
-so that distribution is permitted only in or among countries not thus
-excluded.  In such case, this License incorporates the limitation as if
-written in the body of this License.
-
-  13. The Free Software Foundation may publish revised and/or new
-versions of the Library General Public License from time to time.
-Such new versions will be similar in spirit to the present version,
-but may differ in detail to address new problems or concerns.
-
-Each version is given a distinguishing version number.  If the Library
-specifies a version number of this License which applies to it and
-"any later version", you have the option of following the terms and
-conditions either of that version or of any later version published by
-the Free Software Foundation.  If the Library does not specify a
-license version number, you may choose any version ever published by
-the Free Software Foundation.
-
-  14. If you wish to incorporate parts of the Library into other free
-programs whose distribution conditions are incompatible with these,
-write to the author to ask for permission.  For software which is
-copyrighted by the Free Software Foundation, write to the Free
-Software Foundation; we sometimes make exceptions for this.  Our
-decision will be guided by the two goals of preserving the free status
-of all derivatives of our free software and of promoting the sharing
-and reuse of software generally.
-
-			    NO WARRANTY
-
-  15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
-WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
-EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
-OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
-KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
-IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
-PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
-LIBRARY IS WITH YOU.  SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
-THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
-
-  16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
-WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
-AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
-FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
-CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
-LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
-RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
-FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
-SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
-DAMAGES.
-
-		     END OF TERMS AND CONDITIONS
-
-     Appendix: How to Apply These Terms to Your New Libraries
-
-  If you develop a new library, and you want it to be of the greatest
-possible use to the public, we recommend making it free software that
-everyone can redistribute and change.  You can do so by permitting
-redistribution under these terms (or, alternatively, under the terms of the
-ordinary General Public License).
-
-  To apply these terms, attach the following notices to the library.  It is
-safest to attach them to the start of each source file to most effectively
-convey the exclusion of warranty; and each file should have at least the
-"copyright" line and a pointer to where the full notice is found.
-
-    <one line to give the library's name and a brief idea of what it does.>
-    Copyright (C) <year>  <name of author>
-
-    This library is free software; you can redistribute it and/or
-    modify it under the terms of the GNU Library General Public
-    License as published by the Free Software Foundation; either
-    version 2 of the License, or (at your option) any later version.
-
-    This library is distributed in the hope that it will be useful,
-    but WITHOUT ANY WARRANTY; without even the implied warranty of
-    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the GNU
-    Library General Public License for more details.
-
-    You should have received a copy of the GNU Library General Public
-    License along with this library; if not, write to the Free
-    Software Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA.
-
-Also add information on how to contact you by electronic and paper mail.
-
-You should also get your employer (if you work as a programmer) or your
-school, if any, to sign a "copyright disclaimer" for the library, if
-necessary.  Here is a sample; alter the names:
-
-  Yoyodyne, Inc., hereby disclaims all copyright interest in the
-  library `Frob' (a library for tweaking knobs) written by James Random Hacker.
-
-  <signature of Ty Coon>, 1 April 1990
-  Ty Coon, President of Vice
-
-That's all there is to it!

+                    GNU GENERAL PUBLIC LICENSE
+                       Version 2, June 1991
+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.,
+ 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                            Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users.  This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it.  (Some other Free Software Foundation software is covered by
+the GNU Lesser General Public License instead.)  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+  To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have.  You must make sure that they, too, receive or can get the
+source code.  And you must show them these terms so they know their
+rights.
+
+  We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+  Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software.  If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+  Finally, any free program is threatened constantly by software
+patents.  We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary.  To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                    GNU GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License.  The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language.  (Hereinafter, translation is included without limitation in
+the term "modification".)  Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+  1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+  2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) You must cause the modified files to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    b) You must cause any work that you distribute or publish, that in
+    whole or in part contains or is derived from the Program or any
+    part thereof, to be licensed as a whole at no charge to all third
+    parties under the terms of this License.
+
+    c) If the modified program normally reads commands interactively
+    when run, you must cause it, when started running for such
+    interactive use in the most ordinary way, to print or display an
+    announcement including an appropriate copyright notice and a
+    notice that there is no warranty (or else, saying that you provide
+    a warranty) and that users may redistribute the program under
+    these conditions, and telling the user how to view a copy of this
+    License.  (Exception: if the Program itself is interactive but
+    does not normally print such an announcement, your work based on
+    the Program is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+    a) Accompany it with the complete corresponding machine-readable
+    source code, which must be distributed under the terms of Sections
+    1 and 2 above on a medium customarily used for software interchange; or,
+
+    b) Accompany it with a written offer, valid for at least three
+    years, to give any third party, for a charge no more than your
+    cost of physically performing source distribution, a complete
+    machine-readable copy of the corresponding source code, to be
+    distributed under the terms of Sections 1 and 2 above on a medium
+    customarily used for software interchange; or,
+
+    c) Accompany it with the information you received as to the offer
+    to distribute corresponding source code.  (This alternative is
+    allowed only for noncommercial distribution and only if you
+    received the program in object code or executable form with such
+    an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it.  For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable.  However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License.  Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+  5. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Program or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+  6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+  7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded.  In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+  9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation.  If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+  10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission.  For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this.  Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+                            NO WARRANTY
+
+  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+                     END OF TERMS AND CONDITIONS
+
+            How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software; you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation; either version 2 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License along
+    with this program; if not, write to the Free Software Foundation, Inc.,
+    51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+    Gnomovision version 69, Copyright (C) year name of author
+    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary.  Here is a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+  `Gnomovision' (which makes passes at compilers) written by James Hacker.
+
+  <signature of Ty Coon>, 1 April 1989
+  Ty Coon, President of Vice
+
+This General Public License does not permit incorporating your program into
+proprietary programs.  If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library.  If this is what you want to do, use the GNU Lesser General
+Public License instead of this License.

+# NEWS for Ruby 3.0.0
+
+This document is a list of user visible feature changes
+since the **2.7.0** release, except for bug fixes.
+
+Note that each entry is kept so brief that no reason behind or reference
+information is supplied with.  For a full list of changes with all
+sufficient information, see the ChangeLog file or Redmine
+(e.g. `https://bugs.ruby-lang.org/issues/$FEATURE_OR_BUG_NUMBER`).
+
+## Language changes
+
+* Keyword arguments are now separated from positional arguments.
+  Code that resulted in deprecation warnings in Ruby 2.7 will now
+  result in ArgumentError or different behavior. [[Feature #14183]]
+
+* Procs accepting a single rest argument and keywords are no longer
+  subject to autosplatting.  This now matches the behavior of Procs
+  accepting a single rest argument and no keywords.
+  [[Feature #16166]]
+
+    ```ruby
+    pr = proc{|*a, **kw| [a, kw]}
+
+    pr.call([1])
+    # 2.7 => [[1], {}]
+    # 3.0 => [[[1]], {}]
+
+    pr.call([1, {a: 1}])
+    # 2.7 => [[1], {:a=>1}] # and deprecation warning
+    # 3.0 => [[[1, {:a=>1}]], {}]
+    ```
+
+* Arguments forwarding (`...`) now supports leading arguments.
+  [[Feature #16378]]
+
+    ```ruby
+    def method_missing(meth, ...)
+      send(:"do_#{meth}", ...)
+    end
+    ```
+
+* Pattern matching (`case/in`) is no longer experimental. [[Feature #17260]]
+
+* One-line pattern matching is redesigned.  [EXPERIMENTAL]
+
+    * `=>` is added. It can be used like a rightward assignment.
+      [[Feature #17260]]
+
+        ```ruby
+        0 => a
+        p a #=> 0
+
+        {b: 0, c: 1} => {b:}
+        p b #=> 0
+        ```
+
+    * `in` is changed to return `true` or `false`. [[Feature #17371]]
+
+        ```ruby
+        # version 3.0
+        0 in 1 #=> false
+
+        # version 2.7
+        0 in 1 #=> raise NoMatchingPatternError
+        ```
+
+* Find-pattern is added.  [EXPERIMENTAL]
+  [[Feature #16828]]
+
+    ```ruby
+    case ["a", 1, "b", "c", 2, "d", "e", "f", 3]
+    in [*pre, String => x, String => y, *post]
+      p pre  #=> ["a", 1]
+      p x    #=> "b"
+      p y    #=> "c"
+      p post #=> [2, "d", "e", "f", 3]
+    end
+    ```
+
+* Endless method definition is added.  [EXPERIMENTAL]
+  [[Feature #16746]]
+
+    ```ruby
+    def square(x) = x * x
+    ```
+
+* Interpolated String literals are no longer frozen when
+  `# frozen-string-literal: true` is used. [[Feature #17104]]
+
+* Magic comment `shareable_constant_value` added to freeze constants.
+  See {Magic Comments}[rdoc-ref:doc/syntax/comments.rdoc@Magic+Comments] for more details.
+  [[Feature #17273]]
+
+* A {static analysis}[rdoc-label:label-Static+analysis] foundation is
+  introduced.
+    * {RBS}[rdoc-label:label-RBS] is introduced. It is a type definition
+      language for Ruby programs.
+    * {TypeProf}[rdoc-label:label-TypeProf] is experimentally bundled. It is a
+      type analysis tool for Ruby programs.
+
+* Deprecation warnings are no longer shown by default (since Ruby 2.7.2).
+  Turn them on with `-W:deprecated` (or with `-w` to show other warnings too).
+  [[Feature #16345]]
+
+* $SAFE and $KCODE are now normal global variables with no special behavior.
+  C-API methods related to $SAFE have been removed.
+  [[Feature #16131]] [[Feature #17136]]
+
+* yield in singleton class definitions in methods is now a SyntaxError
+  instead of a warning. yield in a class definition outside of a method
+  is now a SyntaxError instead of a LocalJumpError.  [[Feature #15575]]
+
+* When a class variable is overtaken by the same definition in an
+  ancestor class/module, a RuntimeError is now raised (previously,
+  it only issued a warning in verbose mode).  Additionally, accessing a
+  class variable from the toplevel scope is now a RuntimeError.
+  [[Bug #14541]]
+
+* Assigning to a numbered parameter is now a SyntaxError instead of
+  a warning.
+
+## Command line options
+
+### `--help` option
+
+When the environment variable `RUBY_PAGER` or `PAGER` is present and has
+a non-empty value, and the standard input and output are tty, the `--help`
+option shows the help message via the pager designated by the value.
+[[Feature #16754]]
+
+### `--backtrace-limit` option
+
+The `--backtrace-limit` option limits the maximum length of a backtrace.
+[[Feature #8661]]
+
+## Core classes updates
+
+Outstanding ones only.
+
+* Array
+
+    * The following methods now return Array instances instead of
+      subclass instances when called on subclass instances:
+      [[Bug #6087]]
+
+        * Array#drop
+        * Array#drop_while
+        * Array#flatten
+        * Array#slice!
+        * Array#slice / Array#[]
+        * Array#take
+        * Array#take_while
+        * Array#uniq
+        * Array#*
+
+    * Can be sliced with Enumerator::ArithmeticSequence
+
+        ```ruby
+        dirty_data = ['--', 'data1', '--', 'data2', '--', 'data3']
+        dirty_data[(1..).step(2)] # take each second element
+        # => ["data1", "data2", "data3"]
+        ```
+
+* Binding
+
+    * Binding#eval when called with one argument will use "(eval)"
+      for `__FILE__` and 1 for `__LINE__` in the evaluated code.
+      [[Bug #4352]] [[Bug #17419]]
+
+* ConditionVariable
+
+    * ConditionVariable#wait may now invoke the `block`/`unblock` scheduler
+      hooks in a non-blocking context. [[Feature #16786]]
+
+* Dir
+
+    * Dir.glob and Dir.[] now sort the results by default, and
+      accept the `sort:` keyword option.  [[Feature #8709]]
+
+* ENV
+
+    * ENV.except has been added, which returns a hash excluding the
+      given keys and their values.  [[Feature #15822]]
+
+    * Windows: Read ENV names and values as UTF-8 encoded Strings
+      [[Feature #12650]]
+
+* Encoding
+
+    * Added new encoding IBM720.  [[Feature #16233]]
+
+    * Changed default for Encoding.default_external to UTF-8 on Windows
+      [[Feature #16604]]
+
+* Fiber
+
+    * Fiber.new(blocking: true/false) allows you to create non-blocking
+      execution contexts. [[Feature #16786]]
+
+    * Fiber#blocking? tells whether the fiber is non-blocking. [[Feature #16786]]
+
+    * Fiber#backtrace and Fiber#backtrace_locations provide per-fiber backtrace.
+      [[Feature #16815]]
+
+    * The limitation of Fiber#transfer is relaxed. [[Bug #17221]]
+
+* GC
+
+    * GC.auto_compact= and GC.auto_compact have been added to control
+      when compaction runs.  Setting `auto_compact=` to true will cause
+      compaction to occur during major collections.  At the moment,
+      compaction adds significant overhead to major collections, so please
+      test first!  [[Feature #17176]]
+
+* Hash
+
+    * Hash#transform_keys and Hash#transform_keys! now accept a hash that maps
+      keys to new keys.  [[Feature #16274]]
+
+    * Hash#except has been added, which returns a hash excluding the
+      given keys and their values.  [[Feature #15822]]
+
+* IO
+
+    * IO#nonblock? now defaults to `true`. [[Feature #16786]]
+
+    * IO#wait_readable, IO#wait_writable, IO#read, IO#write and other
+      related methods (e.g. IO#puts, IO#gets) may invoke the scheduler hook
+      `#io_wait(io, events, timeout)` in a non-blocking execution context.
+      [[Feature #16786]]
+
+* Kernel
+
+    * Kernel#clone when called with the `freeze: false` keyword will call
+      `#initialize_clone` with the `freeze: false` keyword.
+      [[Bug #14266]]
+
+    * Kernel#clone when called with the `freeze: true` keyword will call
+      `#initialize_clone` with the `freeze: true` keyword, and will
+      return a frozen copy even if the receiver is unfrozen.
+      [[Feature #16175]]
+
+    * Kernel#eval when called with two arguments will use "(eval)"
+      for `__FILE__` and 1 for `__LINE__` in the evaluated code.
+      [[Bug #4352]]
+
+    * Kernel#lambda now warns if called without a literal block.
+      [[Feature #15973]]
+
+    * Kernel.sleep invokes the scheduler hook `#kernel_sleep(...)` in a
+      non-blocking execution context. [[Feature #16786]]
+
+* Module
+
+    * Module#include and Module#prepend now affect classes and modules
+      that have already included or prepended the receiver, mirroring the
+      behavior if the arguments were included in the receiver before
+      the other modules and classes included or prepended the receiver.
+      [[Feature #9573]]
+
+        ```ruby
+        class C; end
+        module M1; end
+        module M2; end
+        C.include M1
+        M1.include M2
+        p C.ancestors #=> [C, M1, M2, Object, Kernel, BasicObject]
+        ```
+
+    * Module#public, Module#protected, Module#private, Module#public_class_method,
+      Module#private_class_method, toplevel "private" and "public" methods
+      now accept single array argument with a list of method names. [[Feature #17314]]
+
+    * Module#attr_accessor, Module#attr_reader, Module#attr_writer and Module#attr
+      methods now return an array of defined method names as symbols.
+      [[Feature #17314]]
+
+    * Module#alias_method now returns the defined alias as a symbol.
+      [[Feature #17314]]
+
+* Mutex
+
+    * `Mutex` is now acquired per-`Fiber` instead of per-`Thread`. This change
+      should be compatible for essentially all usages and avoids blocking when
+      using a scheduler. [[Feature #16792]]
+
+* Proc
+
+    * Proc#== and Proc#eql? are now defined and will return true for
+      separate Proc instances if the procs were created from the same block.
+      [[Feature #14267]]
+
+* Queue / SizedQueue
+
+    * Queue#pop, SizedQueue#push and related methods may now invoke the
+      `block`/`unblock` scheduler hooks in a non-blocking context.
+      [[Feature #16786]]
+
+* Ractor
+
+    * New class added to enable parallel execution. See rdoc-ref:ractor.md for
+      more details.
+
+* Random
+
+    * `Random::DEFAULT` now refers to the `Random` class instead of being a `Random` instance,
+      so it can work with `Ractor`.
+      [[Feature #17322]]
+
+    * `Random::DEFAULT` is deprecated since its value is now confusing and it is no longer global,
+      use `Kernel.rand`/`Random.rand` directly, or create a `Random` instance with `Random.new` instead.
+      [[Feature #17351]]
+
+
+* String

+## Compatibility issues
+
+Excluding feature bug fixes.
+
+* Regexp literals and all Range objects are frozen. [[Feature #8948]] [[Feature #16377]] [[Feature #15504]]
+
+    ```ruby
+    /foo/.frozen? #=> true
+    (42...).frozen? # => true
+    ```
+
+* EXPERIMENTAL: Hash#each consistently yields a 2-element array. [[Bug #12706]]
+
+    * Now `{ a: 1 }.each(&->(k, v) { })` raises an ArgumentError
+      due to lambda's arity check.
+
+* When writing to STDOUT redirected to a closed pipe, no broken pipe
+  error message will be shown now.  [[Feature #14413]]
+
+* `TRUE`/`FALSE`/`NIL` constants are no longer defined.
+
+* Integer#zero? overrides Numeric#zero? for optimization.  [[Misc #16961]]
+
+* Enumerable#grep and Enumerable#grep_v when passed a Regexp and no block no longer modify
+  Regexp.last_match. [[Bug #17030]]
+
+* Requiring 'open-uri' no longer redefines `Kernel#open`.
+  Call `URI.open` directly or `use URI#open` instead. [[Misc #15893]]
+
+* SortedSet has been removed for dependency and performance reasons.
+
+## Stdlib compatibility issues
+
+* Default gems
+
+    * The following libraries are promoted to default gems from stdlib.
+
+        * English
+        * abbrev
+        * base64
+        * drb
+        * debug
+        * erb
+        * find
+        * net-ftp
+        * net-http
+        * net-imap
+        * net-protocol
+        * open-uri
+        * optparse
+        * pp
+        * prettyprint
+        * resolv-replace
+        * resolv
+        * rinda
+        * set
+        * securerandom
+        * shellwords
+        * tempfile
+        * tmpdir
+        * time
+        * tsort
+        * un
+        * weakref
+
+    * The following extensions are promoted to default gems from stdlib.
+
+        * digest
+        * io-nonblock
+        * io-wait
+        * nkf
+        * pathname
+        * syslog
+        * win32ole
+
+* Bundled gems
+
+    * net-telnet and xmlrpc have been removed from the bundled gems.
+      If you are interested in maintaining them, please comment on
+      your plan to https://github.com/ruby/xmlrpc
+      or https://github.com/ruby/net-telnet.
+
+* SDBM has been removed from the Ruby standard library. [[Bug #8446]]
+
+    * The issues of sdbm will be handled at https://github.com/ruby/sdbm
+
+* WEBrick has been removed from the Ruby standard library. [[Feature #17303]]
+
+    * The issues of WEBrick will be handled at https://github.com/ruby/webrick
+
+## C API updates
+
+* C API functions related to $SAFE have been removed.
+  [[Feature #16131]]
+
+* C API header file `ruby/ruby.h` was split. [[GH-2991]]
+
+    This should have no impact on extension libraries,
+    but users might experience slow compilations.
+
+* Memory view interface [EXPERIMENTAL]
+
+    * The memory view interface is a C-API set to exchange a raw memory area,
+      such as a numeric array or a bitmap image, between extension libraries.
+      The extension libraries can share also the metadata of the memory area
+      that consists of the shape, the element format, and so on.
+      Using these kinds of metadata, the extension libraries can share even
+      a multidimensional array appropriately.
+      This feature is designed by referring to Python's buffer protocol.
+      [[Feature #13767]] [[Feature #14722]]
+
+* Ractor related C APIs are introduced (experimental) in "include/ruby/ractor.h".
+
+## Implementation improvements
+
+* New method cache mechanism for Ractor. [[Feature #16614]]
+
+    * Inline method caches pointed from ISeq can be accessed by multiple Ractors
+      in parallel and synchronization is needed even for method caches. However,
+      such synchronization can be overhead so introducing new inline method cache
+      mechanisms, (1) Disposable inline method cache (2) per-Class method cache
+      and (3) new invalidation mechanism. (1) can avoid per-method call
+      synchronization because it only uses atomic operations.
+      See the ticket for more details.
+
+* The number of hashes allocated when using a keyword splat in
+  a method call has been reduced to a maximum of 1, and passing
+  a keyword splat to a method that accepts specific keywords
+  does not allocate a hash.
+
+* `super` is optimized when the same type of method is called in the previous call
+  if it's not refinements or an attr reader or writer.
+
+### JIT
+
+* Performance improvements of JIT-ed code
+
+    * Microarchitectural optimizations
+
+        * Native functions shared by multiple methods are deduplicated on JIT compaction.
+
+        * Decrease code size of hot paths by some optimizations and partitioning cold paths.
+
+    * Instance variables
+
+        * Eliminate some redundant checks.
+
+        * Skip checking a class and a object multiple times in a method when possible.
+
+        * Optimize accesses in some core classes like Hash and their subclasses.
+
+    * Method inlining support for some C methods
+
+        * `Kernel`: `#class`, `#frozen?`
+
+        * `Integer`: `#-@`, `#~`, `#abs`, `#bit_length`, `#even?`, `#integer?`, `#magnitude`,
+          `#odd?`, `#ord`, `#to_i`, `#to_int`, `#zero?`
+
+        * `Struct`: reader methods for 10th or later members
+
+    * Constant references are inlined.
+
+    * Always generate appropriate code for `==`, `nil?`, and `!` calls depending on
+      a receiver class.
+
+    * Reduce the number of PC accesses on branches and method returns.
+
+    * Optimize C method calls a little.
+
+* Compilation process improvements
+
+    * It does not keep temporary files in /tmp anymore.
+
+    * Throttle GC and compaction of JIT-ed code.
+
+    * Avoid GC-ing JIT-ed code when not necessary.
+
+    * GC-ing JIT-ed code is executed in a background thread.
+
+    * Reduce the number of locks between Ruby and JIT threads.
+
+## Static analysis
+
+### RBS
+
+* RBS is a new language for type definition of Ruby programs.
+  It allows writing types of classes and modules with advanced
+  types including union types, overloading, generics, and
+  _interface types_ for duck typing.
+
+* Ruby ships with type definitions for core/stdlib classes.
+
+* `rbs` gem is bundled to load and process RBS files.
+
+### TypeProf
+
+* TypeProf is a type analysis tool for Ruby code based on abstract interpretation.
+
+    * It reads non-annotated Ruby code, tries inferring its type signature, and prints
+      the analysis result in RBS format.
+
+    * Though it supports only a subset of the Ruby language yet, we will continuously
+      improve the coverage of language features, analysis performance, and usability.
+
+```ruby
+# test.rb
+def foo(x)
+  if x > 10
+    x.to_s
+  else
+    nil
+  end
+end
+
+foo(42)
+```
+
+```
+$ typeprof test.rb
+# Classes
+class Object
+  def foo : (Integer) -> String?
+end
+```
+
+## Miscellaneous changes
+
+* Methods using `ruby2_keywords` will no longer keep empty keyword
+  splats, those are now removed just as they are for methods not
+  using `ruby2_keywords`.
+
+* When an exception is caught in the default handler, the error
+  message and backtrace are printed in order from the innermost.
+  [[Feature #8661]]
+
+* Accessing an uninitialized instance variable no longer emits a
+  warning in verbose mode. [[Feature #17055]]

-* What's Ruby
-
-Ruby is the interpreted scripting language for quick and
-easy object-oriented programming.  It has many features to
-process text files and to do system management tasks (as in
-Perl).  It is simple, straight-forward, and extensible.
-
-* Features of Ruby
-
-  + Simple Syntax
-  + *Normal* Object-Oriented features(ex. class, method calls)
-  + *Advanced* Object-Oriented features(ex. Mix-in, Singleton-method)
-  + Operator Overloading
-  + Exception Handling
-  + Iterators and Closures
-  + Garbage Collection
-  + Dynamic Loading of Object files(on some architecture)
-  + Highly Portable(works on many UNIX machines, and on DOS,
-    Windows, Mac, BeOS etc.)
-
-* How to get Ruby
-
-The Ruby distribution can be found on:
-
-  ftp://ftp.ruby-lang.org/pub/lang/ruby/
-
-You can get it by anonymous CVS.  How to check out is:
-
-  $ cvs -d :pserver:anonymous@cvs.ruby-lang.org:/src login
-  (Logging in to anonymous@cvs.ruby-lang.org)
-  CVS password: anonymous
-  $ cvs -z4 -d :pserver:anonymous@cvs.ruby-lang.org:/src checkout ruby
-
-* Mailing list
-
-There is a mailing list to talk about Ruby.
-To subscribe this list, please send the following phrase
-
-	subscribe YourFirstName YourFamilyName
-e.g.
-        subscribe Joseph Smith
-
-in the mail body (not subject) to the address <ruby-talk-ctl@ruby-lang.org>.
-
-* How to compile and install
-
-This is what you need to do to compile and install Ruby:
-
-  1. If ./configure does not exist or is older than configure.in,
-     run autoconf to (re)generate configure.
-
-  2. Run ./configure, which will generate config.h and Makefile.
-
-  3. Edit defines.h if you need.  Probably this step will not need.
-
-  4. Remove comment mark(#) before the module names from ext/Setup (or
-     add module names if not present), if you want to link modules
-     statically.
-
-     If you don't want to compile non static extension modules
-     (probably on architectures which does not allow dynamic loading),
-     remove comment mark from the line "#option nodynamic" in
-     ext/Setup.
-
-  5. Run make.
-
-  6. Optionally, run 'make test' to check whether the compiled Ruby
-     interpreter works well.  If you see the message "test succeeded",
-     your ruby works as it should (hopefully).
-
-  7. Run 'make install'
-
-     You may have to be a super user to install ruby.
-
-If you fail to compile ruby, please send the detailed error report with
-the error log and machine/OS type, to help others.

-This document explains how to make extension libraries for Ruby.
-
-1. Basic knowledge
-
-In C, variables have types and data do not have types.  In contrast,
-Ruby variables do not have static type and data themselves have
-types.  So, data need to be converted across the languages.
-
-Data in Ruby represented C type `VALUE'.  Each VALUE data have its
-data-type.
-
-To retrieve an C data from the VALUE, you need to:
-
- (1) Identify VALUE's data type
- (2) Convert VALUE into C data
-
-Converting to wrong data type may cause serious problems.
-
-
-1.1 Data-types
-
-Ruby interpreter has data-types as below:
-
-	T_NIL		nil
-	T_OBJECT	ordinary object
-	T_CLASS		class
-	T_MODULE	module
-	T_FLOAT		floating point number
-	T_STRING	string
-	T_REGEXP	regular expression
-	T_ARRAY		array
-	T_FIXNUM	Fixnum(31bit integer)
-	T_HASH		associative array
-	T_STRUCT	(Ruby) structure
-	T_BIGNUM	multi precision integer
-	T_TRUE		true
-	T_FALSE		false
-	T_DATA		data
-	T_SYMBOL        symbol
-
-Otherwise, there are several other types used internally:
-
-	T_ICLASS
-	T_MATCH
-	T_UNDEF
-	T_VARMAP
-	T_SCOPE
-	T_NODE
-
-Most of the types are represented by C structures.
-
-1.2 Check Data Type of the VALUE
-
-The macro TYPE() defined in ruby.h shows data-type of the VALUE.
-TYPE() returns the constant number T_XXXX described above.  To handle
-data-types, the code will be like:
-
-  switch (TYPE(obj)) {
-    case T_FIXNUM:
-      /* process Fixnum */
-      break;
-    case T_STRING:
-      /* process String */
-      break;
-    case T_ARRAY:
-      /* process Array */
-      break;
-    default:
-      /* raise exception */
-      rb_raise(rb_eTypeError, "not valid value");
-      break;
-  }
-
-There is the data-type check function.
-
-  void Check_Type(VALUE value, int type)
-
-It raises an exception, if the VALUE does not have the type specified.
-
-There are faster check-macros for fixnums and nil.
-
-  FIXNUM_P(obj)
-  NIL_P(obj)
-
-1.3 Convert VALUE into C data
-
-The data for type T_NIL, T_FALSE, T_TRUE are nil, true, false
-respectively.  They are singletons for the data type.
-
-The T_FIXNUM data is the 31bit length fixed integer (63bit length on
-some machines), which can be convert to the C integer by using
-FIX2INT() macro.  There also be NUM2INT() which converts any Ruby
-numbers into C integer.  The NUM2INT() macro includes type check, so
-the exception will be raised if conversion failed.
-
-Other data types have corresponding C structures, e.g. struct RArray
-for T_ARRAY etc.  VALUE of the type which has corresponding structure
-can be cast to retrieve the pointer to the struct.  The casting macro
-RXXXX for each data type like RARRAY(obj).  see "ruby.h".
-
-For example, `RSTRING(size)->len' is the way to get the size of the
-Ruby String object.  The allocated region can be accessed by
-`RSTRING(str)->ptr'.  For arrays, `RARRAY(ary)->len' and
-`RARRAY(ary)->ptr' respectively.
-
-Notice: Do not change the value of the structure directly, unless you
-are responsible about the result.  It will be the cause of interesting
-bugs.
-
-1.4 Convert C data into VALUE
-
-To convert C data to the values of Ruby:
-
-  * FIXNUM
-
-    left shift 1 bit, and turn on LSB.
-
-  * Other pointer values
-
-    cast to VALUE.
-
-You can determine whether VALUE is pointer or not, by checking LSB.  
-
-Notice Ruby does not allow arbitrary pointer value to be VALUE.  They
-should be pointers to the structures which Ruby knows.  The known
-structures are defined in <ruby.h>.
-
-To convert C numbers to Ruby value, use these macros.
-
-  INT2FIX()	for integers within 31bits.
-  INT2NUM()	for arbitrary sized integer.
-
-INT2NUM() converts integers into Bignums, if it is out of FIXNUM
-range, but bit slower.
-
-1.5 Manipulate Ruby data
-
-As I already told, it is not recommended to modify object's internal
-structure.  To manipulate objects, use functions supplied by Ruby
-interpreter.  Useful functions are listed below (not all):
-
- String functions
-
-  rb_str_new(const char *ptr, long len)
-
-    Creates a new Ruby string.
-
-  rb_str_new2(const char *ptr)
-
-    Creates a new Ruby string from C string.  This is equivalent to
-    rb_str_new(ptr, strlen(ptr)).
-
-  rb_tainted_str_new(const char *ptr, long len)
-
-    Creates a new tainted Ruby string.  Strings from external data
-    should be tainted.
-
-  rb_tainted_str_new2(const char *ptr)
-
-    Creates a new tainted Ruby string from C string.
-
-  rb_str_cat(VALUE str, const char *ptr, long len)
-
-    Appends len bytes data from ptr to the Ruby string.
-
- Array functions
-
-  rb_ary_new()
-
-    Creates an array with no element.
-
-  rb_ary_new2(long len)
-
-    Creates an array with no element, with allocating internal buffer
-    for len elements.
-
-  rb_ary_new3(long n, ...)
-
-    Creates an n-elements array from arguments.
-
-  rb_ary_new4(long n, VALUE *elts)
-
-    Creates an n-elements array from C array.
-
-  rb_ary_push(VALUE ary, VALUE val)
-  rb_ary_pop(VALUE ary)
-  rb_ary_shift(VALUE ary)
-  rb_ary_unshift(VALUE ary, VALUE val)
-
-    Array operations.  The first argument to each functions must be an 
-    array.  They may dump core if other types given.
-
-2. Extend Ruby with C
-
-2.1 Add new features to Ruby
-
-You can add new features (classes, methods, etc.) to the Ruby
-interpreter.  Ruby provides the API to define things below:
-
- * Classes, Modules
- * Methods, Singleton Methods
- * Constants
-
-2.1.1 Class/module definition
-
-To define class or module, use functions below:
-
-  VALUE rb_define_class(const char *name, VALUE super)
-  VALUE rb_define_module(const char *name)
-
-These functions return the newly created class or module.  You may
-want to save this reference into the variable to use later.
-
-To define nested class or module, use functions below:
-
-  VALUE rb_define_class_under(VALUE outer, const char *name, VALUE super)
-  VALUE rb_define_module_under(VALUE outer, const char *name)
-
-2.1.2 Method/singleton method definition
-
-To define methods or singleton methods, use functions below:
-
-  void rb_define_method(VALUE klass, const char *name, 
-		        VALUE (*func)(), int argc)
-
-  void rb_define_singleton_method(VALUE object, const char *name, 
-			          VALUE (*func)(), int argc)
-
-The `argc' represents the number of the arguments to the C function,
-which must be less than 17.  But I believe you don't need that much. :-)
-
-If `argc' is negative, it specifies calling sequence, not number of
-the arguments.  
-
-If argc is -1, the function will be called like:
-
-  VALUE func(int argc, VALUE *argv, VALUE obj)
-
-where argc is the actual number of arguments, argv is the C array of
-the arguments, and obj is the receiver.
-
-if argc is -2, the arguments are passed in Ruby array. The function
-will be called like:
-
-  VALUE func(VALUE obj, VALUE args)
-
-where obj is the receiver, and args is the Ruby array containing
-actual arguments.
-
-There're two more functions to define method.  One is to define
-private method:
-
-  void rb_define_private_method(VALUE klass, const char *name, 
-			        VALUE (*func)(), int argc)
-
-The other is to define module function, which is private AND singleton
-method of the module.  For example, sqrt is the module function
-defined in Math module.  It can be call in the form like:
-
-  Math.sqrt(4)
-
-or
-
-  include Math
-  sqrt(4)
-
-To define module function
-
-  void rb_define_module_function(VALUE module, const char *name, 
-				 VALUE (*func)(), int argc)
-
-Oh, in addition, function-like method, which is private method defined
-in Kernel module, can be defined using:
-
-  void rb_define_global_function(const char *name, VALUE (*func)(), int argc)
-
-To define alias to the method,
-
-  void rb_define_alias(VALUE module, const char* new, const char* old);
-
-2.1.3 Constant definition
-
-We have 2 functions to define constants:
-
-  void rb_define_const(VALUE klass, const char *name, VALUE val)
-  void rb_define_global_const(const char *name, VALUE val)
-
-The former is to define constant under specified class/module.  The
-latter is to define global constant.
-
-2.2 Use Ruby features from C
-
-There are several ways to invoke Ruby's features from C code.
-
-2.2.1 Evaluate Ruby Program in String
-
-Easiest way to call Ruby's function from C program is to evaluate the
-string as Ruby program.  This function will do the job.
-
-  VALUE rb_eval_string(const char *str)
-
-Evaluation is done under current context, thus current local variables
-of the innermost method (which is defined by Ruby) can be accessed.
-
-2.2.2 ID or Symbol
-
-You can invoke methods directly, without parsing the string.  First I
-need to explain about symbols (which data type is ID).  ID is the
-integer number to represent Ruby's identifiers such as variable names.
-It can be accessed from Ruby in the form like:
-
- :Identifier
-
-You can get the symbol value from string within C code, by using
-
-  rb_intern(const char *name)
-
-2.2.3 Invoke Ruby method from C
-
-To invoke methods directly, you can use the function below
-
-  VALUE rb_funcall(VALUE recv, ID mid, int argc, ...)
-
-This function invokes the method of the recv, which name is specified
-by the symbol mid.
-
-2.2.4 Accessing the variables and constants
-
-You can access class variables, and instance variables using access
-functions.  Also, global variables can be shared between both worlds.
-There's no way to access Ruby's local variables.
-
-The functions to access/modify instance variables are below:
-
-  VALUE rb_ivar_get(VALUE obj, ID id)
-  VALUE rb_ivar_set(VALUE obj, ID id, VALUE val)
-
-id must be the symbol, which can be retrieved by rb_intern().
-
-To access the constants of the class/module:
-
-  VALUE rb_const_get(VALUE obj, ID id)
-
-See 2.1.3 for defining new constant.
-
-3. Information sharing between Ruby and C
-
-3.1 Ruby constant that C can be accessed from C
-
-Following Ruby constants can be referred from C.
-
-  Qtrue
-  Qfalse
-
-Boolean values.  Qfalse is false in the C also (i.e. 0).
-
-  Qnil
-
-Ruby nil in C scope.
-
-3.2 Global variables shared between C and Ruby
-
-Information can be shared between two worlds, using shared global
-variables.  To define them, you can use functions listed below:
-
-  void rb_define_variable(const char *name, VALUE *var)
-
-This function defines the variable which is shared by the both world.
-The value of the global variable pointed by `var', can be accessed
-through Ruby's global variable named `name'.
-
-You can define read-only (from Ruby, of course) variable by the
-function below.
-
-  void rb_define_readonly_variable(const char *name, VALUE *var)
-
-You can defined hooked variables.  The accessor functions (getter and
-setter) are called on access to the hooked variables.
-
-  void rb_define_hooked_variable(constchar *name, VALUE *var,
-				 VALUE (*getter)(), void (*setter)())
-
-If you need to supply either setter or getter, just supply 0 for the
-hook you don't need.  If both hooks are 0, rb_define_hooked_variable()
-works just like rb_define_variable().
-
-  void rb_define_virtual_variable(const char *name,
-				  VALUE (*getter)(), void (*setter)())
-
-This function defines the Ruby global variable without corresponding C
-variable.  The value of the variable will be set/get only by hooks.
-
-The prototypes of the getter and setter functions are as following:
-
-  (*getter)(ID id, void *data, struct global_entry* entry);
-  (*setter)(VALUE val, ID id, void *data, struct global_entry* entry);
-
-3.3 Encapsulate C data into Ruby object
-
-To wrapping and objectify the C pointer as Ruby object (so called
-DATA), use Data_Wrap_Struct().
-
-  Data_Wrap_Struct(klass, mark, free, ptr)
-
-Data_Wrap_Struct() returns a created DATA object.  The klass argument
-is the class for the DATA object.  The mark argument is the function
-to mark Ruby objects pointed by this data.  The free argument is the
-function to free the pointer allocation.  The functions, mark and
-free, will be called from garbage collector.
-
-You can allocate and wrap the structure in one step.
-
-  Data_Make_Struct(klass, type, mark, free, sval)
-
-This macro returns an allocated Data object, wrapping the pointer to
-the structure, which is also allocated.  This macro works like:
-
-  (sval = ALLOC(type), Data_Wrap_Struct(klass, mark, free, sval))
-
-Arguments, klass, mark, free, works like their counterpart of
-Data_Wrap_Struct().  The pointer to allocated structure will be
-assigned to sval, which should be the pointer to the type specified.
-
-To retrieve the C pointer from the Data object, use the macro
-Data_Get_Struct().
-
-  Data_Get_Struct(obj, type, sval)
-
-The pointer to the structure will be assigned to the variable sval.
-
-See example below for detail. 
-
-4. Example - Creating dbm extension
-
-OK, here's the example to make extension library.  This is the
-extension to access dbm.  The full source is included in ext/
-directory in the Ruby's source tree.
-
-(1) make the directory
-
-  % mkdir ext/dbm
-
-Make a directory for the extension library under ext directory.
-
-(2) create MANIFEST file
-
-  % cd ext/dbm
-  % touch MANIFEST
-
-There should be MANIFEST file in the directory for the extension
-library.  Make empty file now.
-
-(3) design the library
-
-You need to design the library features, before making it.
-
-(4) write C code.
-
-You need to write C code for your extension library.  If your library
-has only one source file, choosing ``LIBRARY.c'' as a file name is
-preferred.  On the other hand, in case your library has plural source
-files, avoid choosing ``LIBRARY.c'' for a file name.  It may conflict
-with intermediate file ``LIBRARY.o'' on some platforms.
-
-Ruby will execute the initializing function named ``Init_LIBRARY'' in
-the library.  For example, ``Init_dbm()'' will be executed when loading
-the library.
-
-Here's the example of an initializing function.
-
---
-Init_dbm()
-{
-    /* define DBM class */
-    cDBM = rb_define_class("DBM", rb_cObject);
-    /* DBM includes Enumerate module */
-    rb_include_module(cDBM, rb_mEnumerable);
-
-    /* DBM has class method open(): arguments are received as C array */
-    rb_define_singleton_method(cDBM, "open", fdbm_s_open, -1);
-
-    /* DBM instance method close(): no args */
-    rb_define_method(cDBM, "close", fdbm_close, 0);
-    /* DBM instance method []: 1 argument */
-    rb_define_method(cDBM, "[]", fdbm_fetch, 1);
-		:
-
-}
---
-
-The dbm extension wrap dbm struct in C world using Data_Make_Struct.
-
---
-struct dbmdata {
-    int  di_size;
-    DBM *di_dbm;
-};
-
-
-obj = Data_Make_Struct(klass, struct dbmdata, 0, free_dbm, dbmp);
---
-
-This code wraps dbmdata structure into Ruby object.  We avoid wrapping
-DBM* directly, because we want to cache size information.
-
-To retrieve dbmdata structure from Ruby object, we define the macro below:
-
---
-#define GetDBM(obj, dbmp) {\
-    Data_Get_Struct(obj, struct dbmdata, dbmp);\
-    if (dbmp->di_dbm == 0) closed_dbm();\
-}
---
-
-This sort of complicated macro do the retrieving and close check for
-the DBM.
-
-There are three kind of way to receiving method arguments.  First, the
-methods with fixed number of arguments receives arguments like this:
-
---
-static VALUE
-fdbm_delete(obj, keystr)
-    VALUE obj, keystr;
-{
-	:
-}
---
-
-The first argument of the C function is the self, the rest are the
-arguments to the method.
-
-Second, the methods with arbitrary number of arguments receives
-arguments like this:
-
---
-static VALUE
-fdbm_s_open(argc, argv, klass)
-    int argc;
-    VALUE *argv;
-    VALUE klass;
-{
-	:
-    if (rb_scan_args(argc, argv, "11", &file, &vmode) == 1) {
-	mode = 0666;		/* default value */
-    }
-	:
-}
---
-
-The first argument is the number of method arguments.  the second
-argument is the C array of the method arguments.  And the third
-argument is the receiver of the method.
-
-You can use the function rb_scan_args() to check and retrieve the
-arguments.  For example "11" means, the method requires at least one
-argument, and at most receives two arguments.
-
-The methods with arbitrary number of arguments can receives arguments
-by Ruby's array, like this:
-
---
-static VALUE
-fdbm_indexes(obj, args)
-    VALUE obj, args;
-{
-	:
-}
---
-
-The first argument is the receiver, the second one is the Ruby array
-which contains the arguments to the method.
-
-** Notice
-
-GC should know about global variables which refers Ruby's objects, but
-not exported to the Ruby world.  You need to protect them by
-
-  void rb_global_variable(VALUE *var)
-
-(5) prepare extconf.rb
-
-If there exists the file named extconf.rb, it will be executed to
-generate Makefile.  If not, compilation scheme try to generate
-Makefile anyway.
-
-The extconf.rb is the file to check compilation condition etc.  You
-need to put
-
-  require 'mkmf'
-
-at the top of the file.  You can use the functions below to check the
-condition.
-
-  have_library(lib, func): check whether library containing function exists.
-  have_func(func, header): check whether function exists
-  have_header(header): check whether header file exists
-  create_makefile(target): generate Makefile
-
-The value of variables below will affect Makefile.
-
-  $CFLAGS: included in CFLAGS make variable (such as -I)
-  $LDFLAGS: included in LDFLAGS make variable (such as -L)
-
-If compilation condition is not fulfilled, you do not call
-``create_makefile''.  Makefile will not generated, compilation will
-not be done.
-
-(6) prepare depend (optional)
-
-If the file named depend exists, Makefile will include that file to
-check dependency.  You can make this file by invoking
-
-  % gcc -MM *.c > depend
-
-It's no harm.  Prepare it.
-
-(7) put file names into MANIFEST (optional)
-
-  % find * -type f -print > MANIFEST
-  % vi MANIFEST
-
-Append file names into MANIFEST.  The compilation scheme requires
-MANIFEST only to be exist.  But, you'd better take this step to
-distinguish required files.
-
-(8) generate Makefile
-
-Try generate Makefile by:
-
-  ruby extconf.rb
-
-You don't need this step, if you put extension library under ext
-directory of the ruby source tree.  In that case, compilation of the
-interpreter will do this step for you.
-
-(9) make
-
-Type
-
-  make
-
-to compile your extension.  You don't need this step neither, if you
-put extension library under ext directory of the ruby source tree.
-
-(9) debug
-
-You may need to rb_debug the extension.  The extensions can be linked
-statically by adding directory name in the ext/Setup file, so that you
-can inspect the extension with the debugger.
-
-(10) done, now you have the extension library
-
-You can do anything you want with your library.  The author of Ruby
-will not claim any restriction about your code depending Ruby API.
-Feel free to use, modify, distribute or sell your program.

-Appendix B. Ruby extension API reference
-
-** Types
-
- VALUE
-
-The type for Ruby object.  Actual structures are defined in ruby.h,
-such as struct RString, etc.  To refer the values in structures, use
-casting macros like RSTRING(obj).
-
-** Variables and constants
-
- Qnil
-
-const: nil object
-
- Qtrue
-
-const: true object(default true value)
-
- Qfalse
-
-const: false object
-
-** C pointer wrapping
-
- Data_Wrap_Struct(VALUE klass, void (*mark)(), void (*free)(), void *sval)
-
-Wrap C pointer into Ruby object.  If object has references to other
-Ruby object, they should be marked by using mark function during GC
-process.  Otherwise, mark should be 0.  When this object is no longer
-referred by anywhere, the pointer will be discarded by free function.
-
- Data_Make_Struct(klass, type, mark, free, sval)
-
-This macro allocates memory using malloc(), assigns it to the variable
-sval, and returns the DATA encapsulating the pointer to memory region.
-
- Data_Get_Struct(data, type, sval)
-
-This macro retrieves the pointer value from DATA, and assigns it to
-the variable sval. 
-
-** defining class/module
-
- VALUE rb_define_class(const char *name, VALUE super)
-
-Defines new Ruby class as subclass of super.
-
- VALUE rb_define_class_under(VALUE module, const char *name, VALUE super)
-
-Creates new Ruby class as subclass of super, under the module's
-namespace.
-
- VALUE rb_define_module(const char *name)
-
-Defines new Ruby module.
-
- VALUE rb_define_module_under(VALUE module, const char *name, VALUE super)
-
-Defines new Ruby module, under the module's namespace.
-
- void rb_include_module(VALUE klass, VALUE module)
-
-Includes module into class.  If class already includes it, just
-ignore.
-
- void rb_extend_object(VALUE object, VALUE module)
-
-Extend the object with module's attribute.
-
-** Defining Global Variables
-
- void rb_define_variable(const char *name, VALUE *var)
-
-Defines a global variable which is shared between C and Ruby.  If name
-contains the character which is not allowed to be part of the symbol,
-it can't be seen from Ruby programs.
-
- void rb_define_readonly_variable(const char *name, VALUE *var)
-
-Defines a read-only global variable.  Works just like
-rb_define_variable(), except defined variable is read-only.
-
- void rb_define_virtual_variable(const char *name,
-				 VALUE (*getter)(), VALUE (*setter)())
-
-Defines a virtual variable, whose behavior is defined by pair of C
-functions.  The getter function is called when the variable is
-referred.  The setter function is called when the value is set to the
-variable.  The prototype for getter/setter functions are:
-
-	VALUE getter(ID id)
-	void setter(VALUE val, ID id)
-
-The getter function must return the value for the access.
-
- void rb_define_hooked_variable(const char *name, VALUE *var,
-				VALUE (*getter)(), VALUE (*setter)())
-
-Defines hooked variable.  It's virtual variable with C variable.  The
-getter is called as
-
-	VALUE getter(ID id, VALUE *var)
-
-returning new value.  The setter is called as
-
-	void setter(VALUE val, ID id, VALUE *var)
-
-GC requires to mark the C global variables which hold Ruby values.
-
- void rb_global_variable(VALUE *var)
-
-Tells GC to protect these variables.
-
-** Constant Definition
-
- void rb_define_const(VALUE klass, const char *name, VALUE val)
-
-Defines a new constant under the class/module.
-
- void rb_define_global_const(const char *name, VALUE val)
-
-Defines global constant.  This is just work as
-
-     rb_define_const(cKernal, name, val)
-
-** Method Definition
-
- rb_define_method(VALUE klass, const char *name, VALUE (*func)(), int argc)
-
-Defines a method for the class.  func is the function pointer.  argc
-is the number of arguments.  if argc is -1, the function will receive
-3 arguments argc, argv, and self.  if argc is -2, the function will
-receive 2 arguments, self and args, where args is the Ruby array of
-the method arguments.
-
- rb_define_private_method(VALUE klass, const char *name, VALUE (*func)(), int argc)
-
-Defines a private method for the class.  Arguments are same as
-rb_define_method().
-
- rb_define_singleton_method(VALUE klass, const char *name, VALUE (*func)(), int argc)
-
-Defines a singleton method.  Arguments are same as rb_define_method().
-
- rb_scan_args(int argc, VALUE *argv, const char *fmt, ...)
-
-Retrieve argument from argc, argv.  The fmt is the format string for
-the arguments, such as "12" for 1 non-optional argument, 2 optional
-arguments.  If `*' appears at the end of fmt, it means the rest of
-the arguments are assigned to corresponding variable, packed in
-array.
-
-** Invoking Ruby method
-
- VALUE rb_funcall(VALUE recv, ID mid, int narg, ...)
-
-Invokes the method.  To retrieve mid from method name, use rb_intern().
-
- VALUE rb_funcall2(VALUE recv, ID mid, int argc, VALUE *argv)
-
-Invokes method, passing arguments by array of values.
-
- VALUE rb_eval_string(const char *str)
-
-Compiles and executes the string as Ruby program.
-
- ID rb_intern(const char *name)
-
-Returns ID corresponding the name.
-
- char *rb_id2name(ID id)
-
-Returns the name corresponding ID.
-
- char *rb_class2name(VALUE klass)
-
-Returns the name of the class.
-
- int rb_respond_to(VALUE object, ID id)
-
-Returns true if the object responds to the message specified by id.
-
-** Instance Variables
-
- VALUE rb_iv_get(VALUE obj, const char *name)
-
-Retrieve the value of the instance variable.  If the name is not
-prefixed by `@', that variable shall be inaccessible from Ruby.
-
- VALUE rb_iv_set(VALUE obj, const char *name, VALUE val)
-
-Sets the value of the instance variable.
-
-** Control Structure
-
- VALUE rb_iterate(VALUE (*func1)(), void *arg1, VALUE (*func2)(), void *arg2)
-
-Calls the function func1, supplying func2 as the block.  func1 will be
-called with the argument arg1.  func2 receives the value from yield as
-the first argument, arg2 as the second argument.
- 
- VALUE rb_yield(VALUE val)
-
-Evaluates the block with value val.
-
- VALUE rb_rescue(VALUE (*func1)(), void *arg1, VALUE (*func2)(), void *arg2)
-
-Calls the function func1, with arg1 as the argument.  If exception
-occurs during func1, it calls func2 with arg2 as the argument.  The
-return value of rb_rescue() is the return value from func1 if no
-exception occurs, from func2 otherwise.
-
- VALUE rb_ensure(VALUE (*func1)(), void *arg1, void (*func2)(), void *arg2)
-
-Calls the function func1 with arg1 as the argument, then calls func2
-with arg2, whenever execution terminated.  The return value from
-rb_ensure() is that of func1.
-
-** Exceptions and Errors
-
- void rb_warn(const char *fmt, ...)
-
-Prints warning message according to the printf-like format.
-
- void rb_warning(const char *fmt, ...)
-
-Prints warning message according to the printf-like format, if
-$VERBOSE is true.
-
- void rb_raise(VALUE exception, const char *fmt, ...)
-
-Raises an exception of class exception.  The fmt is the format string
-just like printf().
-
- void rb_fatal(const char *fmt, ...)
-
-Raises fatal error, terminates the interpreter.  No exception handling
-will be done for fatal error, but ensure blocks will be executed.
-
- void rb_bug(const char *fmt, ...)
-
-Terminates the interpreter immediately.  This function should be
-called under the situation caused by the bug in the interpreter.  No
-exception handling nor ensure execution will be done.
-
-** Initialize and Starts the Interpreter
-
-The embedding API are below (not needed for extension libraries):
-
- void ruby_init()
-
-Initializes the interpreter.
-
- void ruby_options(int argc, char **argv)
-
-Process command line arguments for the interpreter.
-
- void ruby_run()
-
-Starts execution of the interpreter.
-
- void ruby_script(char *name)
-
-Specifies the name of the script ($0).
-
-Appendix B. Functions Available in extconf.rb
-
-These functions are available in extconf.rb:
-
- have_library(lib, func)
-
-Checks whether library which contains specified function exists.
-Returns true if the library exists.
-
- find_library(lib, func, path...)
-
-Checks whether library which contains specified function exists in
-path.  Returns true if the library exists.
-
- have_func(func, header)
-
-Checks whether func exists with header.  Returns true if the function
-exists.  To check functions in the additional library, you need to
-check that library first using have_library().
-
- have_header(header)
-
-Checks whether header exists.  Returns true if the header file exists.
-
- create_makefile(target)
-
-Generates the Makefile for the extension library.  If you don't invoke
-this method, the compilation will not be done.
-
- with_config(withval[, default=nil])
-
-Parses the command line options and returns the value specified by
---with-<withval>.
-
- dir_config(target[, default_dir])
- dir_config(target[, default_include, default_lib])
-
-Parses the command line options and adds the directories specified by
---with-<target>-dir, --with-<target>-include, and/or --with-<target>-lib
-to $CFLAGS and/or $LDFLAGS.  --with-<target>-dir=/path is equivalent to
---with-<target>-include=/path/include --with-<target>-lib=/path/lib.
-Returns an array of the added directories ([include_dir, lib_dir]).

+# Rubyとは
+
+Rubyはシンプルかつ強力なオブジェクト指向スクリプト言語です． Rubyは純粋なオブジェクト指向言語として設計されているので，
+オブジェクト指向プログラミングを手軽に行う事が出来ます．もちろん普通の手続き型のプログラミングも可能です．
+
+Rubyはテキスト処理関係の能力などに優れ，Perlと同じくらい強力です．さらにシンプルな文法と，
+例外処理やイテレータなどの機構によって，より分かりやすいプログラミングが出来ます．
+
+## Rubyの特長
+
+*   シンプルな文法
+*   普通のオブジェクト指向機能(クラス，メソッドコールなど)
+*   特殊なオブジェクト指向機能(Mixin，特異メソッドなど)
+*   演算子オーバーロード
+*   例外処理機能
+*   イテレータとクロージャ
+*   ガーベージコレクタ
+*   ダイナミックローディング (アーキテクチャによる)
+*   移植性が高い．多くのUnix-like/POSIX互換プラットフォーム上で動くだけでなく，Windows， macOS，
+    Haikuなどの上でも動く cf.
+    https://github.com/ruby/ruby/blob/master/doc/contributing.rdoc#platform-maintainers

+
+他のブランチの一覧は次のコマンドで見られます．
+
+    $ svn ls https://svn.ruby-lang.org/repos/ruby/branches/
+
+
+## ホームページ
+
+RubyのホームページのURLは
+
+https://www.ruby-lang.org/
+
+です．
+
+## メーリングリスト
+
+Rubyのメーリングリストがあります．参加希望の方は [ruby-list-request@ruby-lang.org] まで本文に
+
+    subscribe
+
+と書いて送って下さい．
+
+Ruby開発者向けメーリングリストもあります．こちらではrubyのバグ，将来の仕様拡張など実装上の問題について議論されています．
+参加希望の方は [ruby-dev-request@ruby-lang.org] までruby-listと同様の方法でメールしてください．
+
+Ruby拡張モジュールについて話し合うruby-extメーリングリストと数学関係の話題について話し合うruby-mathメーリングリストと
+英語でrubyについて話し合うruby-talkメーリングリストもあります．参加方法はどれも同じです．
+
+[ruby-list-request@ruby-lang.org]: mailto:ruby-list-request@ruby-lang.org?subject=Join%20Ruby%20Mailing%20List&body=subscribe
+[ruby-dev-request@ruby-lang.org]: mailto:ruby-dev-request@ruby-lang.org?subject=Join%20Ruby%20Mailing%20List&body=subscribe
+
+## コンパイル・インストール
+
+以下の手順で行ってください．
+
+1.  (Gitリポジトリから取得したソースをビルドする場合) `./autogen.sh` を実行して新しく `configure` を生成する
+
+2.  `configure` を実行して `Makefile` などを生成する
+
+    環境によってはデフォルトのCコンパイラ用オプションが付きます． `configure` オプションで `optflags=..`
+    `warnflags=..` 等で上書きできます．
+
+3.  (必要ならば)`include/ruby/defines.h` を編集する
+
+    多分，必要無いと思います．
+
+4.  (必要ならば)`ext/Setup` に静的にリンクする拡張モジュールを指定する
+
+    `ext/Setup` に記述したモジュールは静的にリンクされます．
+
+    ダイナミックローディングをサポートしていないアーキテクチャでは `Setup` の1行目の「`option nodynamic`」という行のコ
+    メントを外す必要があります．
+    また，このアーキテクチャで拡張モジュールを利用するためには，あらかじめ静的にリンクをしておく必要があります．
+
+5.  `make` を実行してコンパイルする
+
+6.  `make check`でテストを行う．
+
+    「`check succeeded`」と表示されれば成功です．ただしテストに成功しても完璧だと保証されている訳ではありません．
+
+7.  `make install`
+
+    以下のディレクトリを作って，そこにファイルをインストー ルします．
+
+    *   `${DESTDIR}${prefix}/bin`
+    *   `${DESTDIR}${prefix}/include/ruby-${MAJOR}.${MINOR}.${TEENY}`
+    *   `${DESTDIR}${prefix}/include/ruby-${MAJOR}.${MINOR}.${TEENY}/${PLATFORM}`
+    *   `${DESTDIR}${prefix}/lib`
+    *   `${DESTDIR}${prefix}/lib/ruby`
+    *   `${DESTDIR}${prefix}/lib/ruby/${MAJOR}.${MINOR}.${TEENY}`
+    *   `${DESTDIR}${prefix}/lib/ruby/${MAJOR}.${MINOR}.${TEENY}/${PLATFORM}`
+    *   `${DESTDIR}${prefix}/lib/ruby/site_ruby`
+    *   `${DESTDIR}${prefix}/lib/ruby/site_ruby/${MAJOR}.${MINOR}.${TEENY}`
+    *   `${DESTDIR}${prefix}/lib/ruby/site_ruby/${MAJOR}.${MINOR}.${TEENY}/${PLATFORM}`
+    *   `${DESTDIR}${prefix}/lib/ruby/vendor_ruby`
+    *   `${DESTDIR}${prefix}/lib/ruby/vendor_ruby/${MAJOR}.${MINOR}.${TEENY}`
+    *   `${DESTDIR}${prefix}/lib/ruby/vendor_ruby/${MAJOR}.${MINOR}.${TEENY}/${PLATFORM}`
+    *   `${DESTDIR}${prefix}/lib/ruby/gems/${MAJOR}.${MINOR}.${TEENY}`
+    *   `${DESTDIR}${prefix}/share/man/man1`
+    *   `${DESTDIR}${prefix}/share/ri/${MAJOR}.${MINOR}.${TEENY}/system`
+
+
+    RubyのAPIバージョンが'*x.y.z*'であれば，`${MAJOR}`は
+    '*x*'で，`${MINOR}`は'*y*'，`${TEENY}`は'*z*'です．
+
+    **注意**: APIバージョンの `teeny` は，Rubyプログラムのバージョンとは異なることがあります．
+
+    `root` で作業する必要があるかもしれません．
+
+
+もし，コンパイル時にエラーが発生した場合にはエラーのログとマシン，OSの種類を含むできるだけ詳しいレポートを作者に送って下さると他の方のためにもなります．
+
+## 移植
+
+UNIXであれば `configure` がほとんどの差異を吸収してくれるはずですが，思わぬ見落としがあった場合(ある事が多い)，作者にその
+ことを報告すれば，解決できる可能性があります．
+
+アーキテクチャにもっとも依存するのはGC部です．RubyのGCは対象
+のアーキテクチャが`setjmp()`または`getcontext()`によって全てのレジスタを `jmp_buf` や `ucontext_t`
+に格納することと， `jmp_buf` や `ucontext_t` とスタックが32bitアラインメントされていることを仮定
+しています．特に前者が成立しない場合の対応は非常に困難でしょう． 後者の解決は比較的簡単で， `gc.c` でスタックをマークしている
+部分にアラインメントのバイト数だけずらしてマークするコードを追加するだけで済みます．`defined(__mc68000__)`で括られてい
+る部分を参考にしてください．
+
+レジスタウィンドウを持つCPUでは，レジスタウィンドウをスタックにフラッシュするアセンブラコードを追加する必要があるかもしれません．
+

+# What's Ruby
+
+Ruby is an interpreted object-oriented programming language often
+used for web development. It also offers many scripting features
+to process plain text and serialized files, or manage system tasks.
+It is simple, straightforward, and extensible.
+
+## Features of Ruby
+
+*   Simple Syntax
+*   **Normal** Object-oriented Features (e.g. class, method calls)
+*   **Advanced** Object-oriented Features (e.g. mix-in, singleton-method)
+*   Operator Overloading
+*   Exception Handling
+*   Iterators and Closures
+*   Garbage Collection
+*   Dynamic Loading of Object Files (on some architectures)
+*   Highly Portable (works on many Unix-like/POSIX compatible platforms as
+    well as Windows, macOS, etc.) cf.
+    https://github.com/ruby/ruby/blob/master/doc/contributing.rdoc#label-Platform+Maintainers
+
+
+## How to get Ruby
+
+For a complete list of ways to install Ruby, including using third-party tools
+like rvm, see:
+
+https://www.ruby-lang.org/en/downloads/
+
+### Git
+
+The mirror of the Ruby source tree can be checked out with the following command:
+
+    $ git clone https://github.com/ruby/ruby.git
+
+There are some other branches under development. Try the following command
+to see the list of branches:
+
+    $ git ls-remote https://github.com/ruby/ruby.git
+
+You may also want to use https://git.ruby-lang.org/ruby.git (actual master of Ruby source)
+if you are a committer.
+
+### Subversion
+
+Stable branches for older Ruby versions can be checked out with also the
+following command:
+
+    $ svn co https://svn.ruby-lang.org/repos/ruby/branches/ruby_2_6/ ruby
+
+Try the following command to see the list of branches:
+
+    $ svn ls https://svn.ruby-lang.org/repos/ruby/branches/
+
+
+## Ruby home page
+
+https://www.ruby-lang.org/
+
+## Mailing list
+
+There is a mailing list to discuss Ruby. To subscribe to this list, please
+send the following phrase:
+
+    subscribe
+
+in the mail body (not subject) to the address [ruby-talk-request@ruby-lang.org].
+
+[ruby-talk-request@ruby-lang.org]: mailto:ruby-talk-request@ruby-lang.org?subject=Join%20Ruby%20Mailing%20List&body=subscribe
+
+## How to compile and install
+
+1.  If you want to use Microsoft Visual C++ to compile Ruby, read
+    [win32/README.win32](win32/README.win32) instead of this document.
+
+2.  Run `./autogen.sh` to generate configure, when you build the source checked
+    out from the Git repository.
+
+3.  Run `./configure`, which will generate `config.h` and `Makefile`.
+
+    Some C compiler flags may be added by default depending on your
+    environment. Specify `optflags=..` and `warnflags=..` as necessary to
+    override them.
+
+4.  Edit `include/ruby/defines.h` if you need. Usually this step will not be needed.
+
+5.  Remove comment mark(`#`) before the module names from `ext/Setup` (or add
+    module names if not present), if you want to link modules statically.
+
+    If you don't want to compile non static extension modules (probably on
+    architectures which do not allow dynamic loading), remove comment mark
+    from the line "`#option nodynamic`" in `ext/Setup`.
+
+    Usually this step will not be needed.
+
+6.  Run `make`.
+
+    * On Mac, set RUBY\_CODESIGN environment variable with a signing identity.
+      It uses the identity to sign `ruby` binary. See also codesign(1).
+
+7.  Optionally, run '`make check`' to check whether the compiled Ruby
+    interpreter works well. If you see the message "`check succeeded`", your
+    Ruby works as it should (hopefully).
+
+8.  Run '`make install`'.
+
+    This command will create the following directories and install files into
+    them.
+
+    *   `${DESTDIR}${prefix}/bin`
+    *   `${DESTDIR}${prefix}/include/ruby-${MAJOR}.${MINOR}.${TEENY}`
+    *   `${DESTDIR}${prefix}/include/ruby-${MAJOR}.${MINOR}.${TEENY}/${PLATFORM}`
+    *   `${DESTDIR}${prefix}/lib`
+    *   `${DESTDIR}${prefix}/lib/ruby`
+    *   `${DESTDIR}${prefix}/lib/ruby/${MAJOR}.${MINOR}.${TEENY}`
+    *   `${DESTDIR}${prefix}/lib/ruby/${MAJOR}.${MINOR}.${TEENY}/${PLATFORM}`
+    *   `${DESTDIR}${prefix}/lib/ruby/site_ruby`
+    *   `${DESTDIR}${prefix}/lib/ruby/site_ruby/${MAJOR}.${MINOR}.${TEENY}`
+    *   `${DESTDIR}${prefix}/lib/ruby/site_ruby/${MAJOR}.${MINOR}.${TEENY}/${PLATFORM}`
+    *   `${DESTDIR}${prefix}/lib/ruby/vendor_ruby`
+    *   `${DESTDIR}${prefix}/lib/ruby/vendor_ruby/${MAJOR}.${MINOR}.${TEENY}`
+    *   `${DESTDIR}${prefix}/lib/ruby/vendor_ruby/${MAJOR}.${MINOR}.${TEENY}/${PLATFORM}`
+    *   `${DESTDIR}${prefix}/lib/ruby/gems/${MAJOR}.${MINOR}.${TEENY}`
+    *   `${DESTDIR}${prefix}/share/man/man1`
+    *   `${DESTDIR}${prefix}/share/ri/${MAJOR}.${MINOR}.${TEENY}/system`
+
+
+    If Ruby's API version is '*x.y.z*', the `${MAJOR}` is '*x*', the
+    `${MINOR}` is '*y*', and the `${TEENY}` is '*z*'.
+
+    **NOTE**: teeny of the API version may be different from one of Ruby's
+    program version
+
+    You may have to be a super user to install Ruby.
+
+If you fail to compile Ruby, please send the detailed error report with the
+error log and machine/OS type, to help others.
+
+Some extension libraries may not get compiled because of lack of necessary
+external libraries and/or headers, then you will need to run '`make distclean-ext`'
+to remove old configuration after installing them in such case.

+ *
+ *  By using binary search, finds a value from this array which meets
+ *  the given condition in <tt>O(log n)</tt> where +n+ is the size of the array.
+ *
+ *  There are two search modes:

+ *  - <b>Find-any mode</b>: the block should return a numeric value.
+ *
+ *  The block should not mix the modes by and sometimes returning +true+ or +false+
+ *  and sometimes returning a numeric value, but this is not checked.
+ *
+ *  <b>Find-Minimum Mode</b>
+ *
+ *  In find-minimum mode, the block always returns +true+ or +false+.
+ *  The further requirement (though not checked) is that

+ *  - <tt>0 <= i < j <= self.size</tt>.
+ *  - The block returns +true+ for <tt>self[i]</tt> and +false+ for <tt>self[j]</tt>.

+ *  Examples:

+ *    a.bsearch {|x| x >= 6 } # => 7

+ *    a.map {|x| x == 7 } # => [false, false, true, false, false]
+ *
+ *  <b>Find-Any Mode</b>
+ *
+ *  In find-any mode, the block always returns a numeric value.
+ *  The further requirement (though not checked) is that
+ *  there are no indexes +i+ and +j+ such that:
+ *  - <tt>0 <= i < j <= self.size</tt>.
+ *  - The block returns a negative value for <tt>self[i]</tt>
+ *    and a positive value for <tt>self[j]</tt>.
+ *  - The block returns a negative value for <tt>self[i]</tt> and zero <tt>self[j]</tt>.
+ *  - The block returns zero for <tt>self[i]</tt> and a positive value for <tt>self[j]</tt>.
+ *
+ *  In find-any mode, method bsearch returns some element
+ *  for which the block returns zero, or +nil+ if no such element is found.
+ *
+ *  Examples:
+ *    a = [0, 4, 7, 10, 12]
+ *    a.bsearch {|element| 7 <=> element } # => 7
+ *    a.bsearch {|element| -1 <=> element } # => nil
+ *    a.bsearch {|element| 5 <=> element } # => nil
+ *    a.bsearch {|element| 15 <=> element } # => nil
+ *
+ *  Less formally: the block is such that:
+ *  - All positive-evaluating elements precede all zero-evaluating elements.
+ *  - All positive-evaluating elements precede all negative-evaluating elements.
+ *  - All zero-evaluating elements precede all negative-evaluating elements.
+ *
+ *  These make sense as blocks in find-any mode:
+ *    a = [0, 4, 7, 10, 12]
+ *    a.map {|element| 7 <=> element } # => [1, 1, 0, -1, -1]
+ *    a.map {|element| -1 <=> element } # => [-1, -1, -1, -1, -1]

+/*
+ *  An \Array is an ordered, integer-indexed collection of objects,
+ *  called _elements_.  Any object may be an \Array element.
+ *
+ *  == \Array Indexes
+ *
+ *  \Array indexing starts at 0, as in C or Java.
+ *
+ *  A positive index is an offset from the first element:
+ *  - Index 0 indicates the first element.
+ *  - Index 1 indicates the second element.
+ *  - ...
+ *
+ *  A negative index is an offset, backwards, from the end of the array:
+ *  - Index -1 indicates the last element.
+ *  - Index -2 indicates the next-to-last element.
+ *  - ...
+ *
+ *  A non-negative index is <i>in range</i> if it is smaller than
+ *  the size of the array.  For a 3-element array:
+ *  - Indexes 0 through 2 are in range.
+ *  - Index 3 is out of range.
+ *
+ *  A negative index is <i>in range</i> if its absolute value is
+ *  not larger than the size of the array.  For a 3-element array:
+ *  - Indexes -1 through -3 are in range.
+ *  - Index -4 is out of range.
+ *
+ *  == Creating Arrays
+ *
+ *  A new array can be created by using the literal constructor
+ *  <code>[]</code>.  Arrays can contain different types of objects.  For
+ *  example, the array below contains an Integer, a String and a Float:
+ *
+ *     ary = [1, "two", 3.0] #=> [1, "two", 3.0]
+ *
+ *  An array can also be created by explicitly calling Array.new with zero, one
+ *  (the initial size of the Array) or two arguments (the initial size and a
+ *  default object).
+ *
+ *     ary = Array.new    #=> []
+ *     Array.new(3)       #=> [nil, nil, nil]
+ *     Array.new(3, true) #=> [true, true, true]
+ *
+ *  Note that the second argument populates the array with references to the
+ *  same object.  Therefore, it is only recommended in cases when you need to
+ *  instantiate arrays with natively immutable objects such as Symbols,
+ *  numbers, true or false.
+ *
+ *  To create an array with separate objects a block can be passed instead.
+ *  This method is safe to use with mutable objects such as hashes, strings or
+ *  other arrays:
+ *
+ *     Array.new(4) {Hash.new}    #=> [{}, {}, {}, {}]
+ *     Array.new(4) {|i| i.to_s } #=> ["0", "1", "2", "3"]
+ *
+ *  This is also a quick way to build up multi-dimensional arrays:
+ *
+ *     empty_table = Array.new(3) {Array.new(3)}
+ *     #=> [[nil, nil, nil], [nil, nil, nil], [nil, nil, nil]]
+ *
+ *  An array can also be created by using the Array() method, provided by
+ *  Kernel, which tries to call #to_ary, then #to_a on its argument.
+ *
+ *	Array({:a => "a", :b => "b"}) #=> [[:a, "a"], [:b, "b"]]
+ *
+ *  == Example Usage
+ *
+ *  In addition to the methods it mixes in through the Enumerable module, the
+ *  Array class has proprietary methods for accessing, searching and otherwise
+ *  manipulating arrays.
+ *
+ *  Some of the more common ones are illustrated below.
+ *
+ *  == Accessing Elements
+ *
+ *  Elements in an array can be retrieved using the Array#[] method.  It can
+ *  take a single integer argument (a numeric index), a pair of arguments
+ *  (start and length) or a range. Negative indices start counting from the end,
+ *  with -1 being the last element.
+ *
+ *     arr = [1, 2, 3, 4, 5, 6]
+ *     arr[2]    #=> 3
+ *     arr[100]  #=> nil
+ *     arr[-3]   #=> 4
+ *     arr[2, 3] #=> [3, 4, 5]
+ *     arr[1..4] #=> [2, 3, 4, 5]
+ *     arr[1..-3] #=> [2, 3, 4]
+ *
+ *  Another way to access a particular array element is by using the #at method
+ *
+ *     arr.at(0) #=> 1
+ *
+ *  The #slice method works in an identical manner to Array#[].
+ *
+ *  To raise an error for indices outside of the array bounds or else to
+ *  provide a default value when that happens, you can use #fetch.
+ *
+ *     arr = ['a', 'b', 'c', 'd', 'e', 'f']
+ *     arr.fetch(100) #=> IndexError: index 100 outside of array bounds: -6...6
+ *     arr.fetch(100, "oops") #=> "oops"
+ *
+ *  The special methods #first and #last will return the first and last
+ *  elements of an array, respectively.
+ *
+ *     arr.first #=> 1
+ *     arr.last  #=> 6
+ *
+ *  To return the first +n+ elements of an array, use #take
+ *
+ *     arr.take(3) #=> [1, 2, 3]
+ *
+ *  #drop does the opposite of #take, by returning the elements after +n+
+ *  elements have been dropped:
+ *
+ *     arr.drop(3) #=> [4, 5, 6]
+ *
+ *  == Obtaining Information about an Array
+ *
+ *  Arrays keep track of their own length at all times.  To query an array
+ *  about the number of elements it contains, use #length, #count or #size.
+ *
+ *    browsers = ['Chrome', 'Firefox', 'Safari', 'Opera', 'IE']
+ *    browsers.length #=> 5
+ *    browsers.count #=> 5
+ *
+ *  To check whether an array contains any elements at all
+ *
+ *    browsers.empty? #=> false
+ *
+ *  To check whether a particular item is included in the array
+ *
+ *    browsers.include?('Konqueror') #=> false
+ *
+ *  == Adding Items to Arrays
+ *
+ *  Items can be added to the end of an array by using either #push or #<<
+ *
+ *    arr = [1, 2, 3, 4]
+ *    arr.push(5) #=> [1, 2, 3, 4, 5]
+ *    arr << 6    #=> [1, 2, 3, 4, 5, 6]
+ *
+ *  #unshift will add a new item to the beginning of an array.
+ *
+ *     arr.unshift(0) #=> [0, 1, 2, 3, 4, 5, 6]
+ *
+ *  With #insert you can add a new element to an array at any position.
+ *
+ *     arr.insert(3, 'apple')  #=> [0, 1, 2, 'apple', 3, 4, 5, 6]
+ *
+ *  Using the #insert method, you can also insert multiple values at once:
+ *
+ *     arr.insert(3, 'orange', 'pear', 'grapefruit')
+ *     #=> [0, 1, 2, "orange", "pear", "grapefruit", "apple", 3, 4, 5, 6]
+ *
+ *  == Removing Items from an Array
+ *
+ *  The method #pop removes the last element in an array and returns it:
+ *
+ *     arr =  [1, 2, 3, 4, 5, 6]
+ *     arr.pop #=> 6
+ *     arr #=> [1, 2, 3, 4, 5]
+ *
+ *  To retrieve and at the same time remove the first item, use #shift:
+ *
+ *     arr.shift #=> 1
+ *     arr #=> [2, 3, 4, 5]
+ *
+ *  To delete an element at a particular index:
+ *
+ *     arr.delete_at(2) #=> 4
+ *     arr #=> [2, 3, 5]
+ *
+ *  To delete a particular element anywhere in an array, use #delete:
+ *
+ *     arr = [1, 2, 2, 3]
+ *     arr.delete(2) #=> 2
+ *     arr #=> [1,3]
+ *
+ *  A useful method if you need to remove +nil+ values from an array is
+ *  #compact:
+ *
+ *     arr = ['foo', 0, nil, 'bar', 7, 'baz', nil]
+ *     arr.compact  #=> ['foo', 0, 'bar', 7, 'baz']
+ *     arr          #=> ['foo', 0, nil, 'bar', 7, 'baz', nil]
+ *     arr.compact! #=> ['foo', 0, 'bar', 7, 'baz']
+ *     arr          #=> ['foo', 0, 'bar', 7, 'baz']
+ *
+ *  Another common need is to remove duplicate elements from an array.
+ *
+ *  It has the non-destructive #uniq, and destructive method #uniq!
+ *
+ *     arr = [2, 5, 6, 556, 6, 6, 8, 9, 0, 123, 556]
+ *     arr.uniq #=> [2, 5, 6, 556, 8, 9, 0, 123]
+ *
+ *  == Iterating over Arrays
+ *
+ *  Like all classes that include the Enumerable module, Array has an each
+ *  method, which defines what elements should be iterated over and how.  In
+ *  case of Array's #each, all elements in the Array instance are yielded to
+ *  the supplied block in sequence.
+ *
+ *  Note that this operation leaves the array unchanged.
+ *
+ *     arr = [1, 2, 3, 4, 5]
+ *     arr.each {|a| print a -= 10, " "}
+ *     # prints: -9 -8 -7 -6 -5
+ *     #=> [1, 2, 3, 4, 5]
+ *
+ *  Another sometimes useful iterator is #reverse_each which will iterate over
+ *  the elements in the array in reverse order.
+ *
+ *     words = %w[first second third fourth fifth sixth]
+ *     str = ""
+ *     words.reverse_each {|word| str += "#{word} "}
+ *     p str #=> "sixth fifth fourth third second first "
+ *
+ *  The #map method can be used to create a new array based on the original
+ *  array, but with the values modified by the supplied block:
+ *
+ *     arr.map {|a| 2*a}     #=> [2, 4, 6, 8, 10]
+ *     arr                   #=> [1, 2, 3, 4, 5]
+ *     arr.map! {|a| a**2}   #=> [1, 4, 9, 16, 25]
+ *     arr                   #=> [1, 4, 9, 16, 25]
+ *
+ *  == Selecting Items from an Array
+ *
+ *  Elements can be selected from an array according to criteria defined in a
+ *  block.  The selection can happen in a destructive or a non-destructive
+ *  manner.  While the destructive operations will modify the array they were
+ *  called on, the non-destructive methods usually return a new array with the
+ *  selected elements, but leave the original array unchanged.
+ *
+ *  === Non-destructive Selection
+ *
+ *     arr = [1, 2, 3, 4, 5, 6]
+ *     arr.select {|a| a > 3}       #=> [4, 5, 6]
+ *     arr.reject {|a| a < 3}       #=> [3, 4, 5, 6]
+ *     arr.drop_while {|a| a < 4}   #=> [4, 5, 6]
+ *     arr                          #=> [1, 2, 3, 4, 5, 6]
+ *
+ *  === Destructive Selection
+ *
+ *  #select! and #reject! are the corresponding destructive methods to #select
+ *  and #reject
+ *
+ *  Similar to #select vs. #reject, #delete_if and #keep_if have the exact
+ *  opposite result when supplied with the same block:
+ *
+ *     arr.delete_if {|a| a < 4}   #=> [4, 5, 6]
+ *     arr                         #=> [4, 5, 6]
+ *
+ *     arr = [1, 2, 3, 4, 5, 6]
+ *     arr.keep_if {|a| a < 4}   #=> [1, 2, 3]
+ *     arr                       #=> [1, 2, 3]

+  # AbstractSyntaxTree provides methods to parse Ruby code into

+  #
+  # This module is MRI specific as it exposes implementation details
+  # of the MRI abstract syntax tree.
+  #
+  # This module is experimental and its API is not stable, therefore it might
+  # change without notice. As examples, the order of children nodes is not
+  # guaranteed, the number of children nodes might change, there is no way to
+  # access children nodes by name, etc.
+  #
+  # If you are looking for a stable API or an API working under multiple Ruby
+  # implementations, consider using the _parser_ gem or Ripper. If you would
+  # like to make RubyVM::AbstractSyntaxTree stable, please join the discussion
+  # at https://bugs.ruby-lang.org/issues/14844.

+## make benchmark
+
+Using `make benchmark`, `make update-benchmark-driver` automatically downloads
+the supported version of benchmark\_driver, and it runs benchmarks with the downloaded
+benchmark\_driver.
+
+```bash
+# Run all benchmarks with the ruby in the $PATH and the built ruby
+make benchmark
+
+# Or compare with specific ruby binary
+make benchmark COMPARE_RUBY="/path/to/ruby --jit"
+
+# Run vm benchmarks
+make benchmark ITEM=vm
+
+# Run some limited benchmarks in ITEM-matched files
+make benchmark ITEM=vm OPTS=--filter=block
+
+# You can specify the benchmark by an exact filename instead of using the default argument:
+# ARGS = $$(find $(srcdir)/benchmark -maxdepth 1 -name '*$(ITEM)*.yml' -o -name '*$(ITEM)*.rb')
+make benchmark ARGS=benchmark/erb_render.yml
+
+# You can specify any option via $OPTS
+make benchmark OPTS="--help"
+
+# With `make benchmark`, some special runner plugins are available:
+#   -r peak, -r size, -r total, -r utime, -r stime, -r cutime, -r cstime
+make benchmark ITEM=vm_bigarray OPTS="-r peak"

+  Hello there, Izchak Miller was my father.  When I was younger I spent 
+  many a night, hunched over the keyboard with a cup of tea, playing 
+  nethack with him and my brother.  my dad was a philosopher with a strong 
+  weakness for fantasy/sci fi.  I remember when he started to get involved 
+  with the Nethack team- my brother's Dungeons and Dragons monster book 
+  found a regular place beside my dad's desk. it's nice to see him living 
+  on in the game he loved so much :-).

+Statement of Purpose
+
+The laws of most jurisdictions throughout the world automatically confer exclusive Copyright and Related Rights (defined below) upon the creator and subsequent owner(s) (each and all, an "owner") of an original work of authorship and/or a database (each, a "Work").
+
+Certain owners wish to permanently relinquish those rights to a Work for the purpose of contributing to a commons of creative, cultural and scientific works ("Commons") that the public can reliably and without fear of later claims of infringement build upon, modify, incorporate in other works, reuse and redistribute as freely as possible in any form whatsoever and for any purposes, including without limitation commercial purposes. These owners may contribute to the Commons to promote the ideal of a free culture and the further production of creative, cultural and scientific works, or to gain reputation or greater distribution for their Work in part through the use and efforts of others.
+
+For these and/or other purposes and motivations, and without any expectation of additional consideration or compensation, the person associating CC0 with a Work (the "Affirmer"), to the extent that he or she is an owner of Copyright and Related Rights in the Work, voluntarily elects to apply CC0 to the Work and publicly distribute the Work under its terms, with knowledge of his or her Copyright and Related Rights in the Work and the meaning and intended legal effect of CC0 on those rights.
+
+1. Copyright and Related Rights. A Work made available under CC0 may be protected by copyright and related or neighboring rights ("Copyright and Related Rights"). Copyright and Related Rights include, but are not limited to, the following:
+
+    the right to reproduce, adapt, distribute, perform, display, communicate, and translate a Work;
+    moral rights retained by the original author(s) and/or performer(s);
+    publicity and privacy rights pertaining to a person's image or likeness depicted in a Work;
+    rights protecting against unfair competition in regards to a Work, subject to the limitations in paragraph 4(a), below;
+    rights protecting the extraction, dissemination, use and reuse of data in a Work;
+    database rights (such as those arising under Directive 96/9/EC of the European Parliament and of the Council of 11 March 1996 on the legal protection of databases, and under any national implementation thereof, including any amended or successor version of such directive); and
+    other similar, equivalent or corresponding rights throughout the world based on applicable law or treaty, and any national implementations thereof.
+
+2. Waiver. To the greatest extent permitted by, but not in contravention of, applicable law, Affirmer hereby overtly, fully, permanently, irrevocably and unconditionally waives, abandons, and surrenders all of Affirmer's Copyright and Related Rights and associated claims and causes of action, whether now known or unknown (including existing as well as future claims and causes of action), in the Work (i) in all territories worldwide, (ii) for the maximum duration provided by applicable law or treaty (including future time extensions), (iii) in any current or future medium and for any number of copies, and (iv) for any purpose whatsoever, including without limitation commercial, advertising or promotional purposes (the "Waiver"). Affirmer makes the Waiver for the benefit of each member of the public at large and to the detriment of Affirmer's heirs and successors, fully intending that such Waiver shall not be subject to revocation, rescission, cancellation, termination, or any other legal or equitable action to disrupt the quiet enjoyment of the Work by the public as contemplated by Affirmer's express Statement of Purpose.
+
+3. Public License Fallback. Should any part of the Waiver for any reason be judged legally invalid or ineffective under applicable law, then the Waiver shall be preserved to the maximum extent permitted taking into account Affirmer's express Statement of Purpose. In addition, to the extent the Waiver is so judged Affirmer hereby grants to each affected person a royalty-free, non transferable, non sublicensable, non exclusive, irrevocable and unconditional license to exercise Affirmer's Copyright and Related Rights in the Work (i) in all territories worldwide, (ii) for the maximum duration provided by applicable law or treaty (including future time extensions), (iii) in any current or future medium and for any number of copies, and (iv) for any purpose whatsoever, including without limitation commercial, advertising or promotional purposes (the "License"). The License shall be deemed effective as of the date CC0 was applied by Affirmer to the Work. Should any part of the License for any reason be judged legally invalid or ineffective under applicable law, such partial invalidity or ineffectiveness shall not invalidate the remainder of the License, and in such case Affirmer hereby affirms that he or she will not (i) exercise any of his or her remaining Copyright and Related Rights in the Work or (ii) assert any associated claims and causes of action with respect to the Work, in either case contrary to Affirmer's express Statement of Purpose.
+
+4. Limitations and Disclaimers.
+
+    No trademark or patent rights held by Affirmer are waived, abandoned, surrendered, licensed or otherwise affected by this document.
+    Affirmer offers the Work as-is and makes no representations or warranties of any kind concerning the Work, express, implied, statutory or otherwise, including without limitation warranties of title, merchantability, fitness for a particular purpose, non infringement, or the absence of latent or other defects, accuracy, or the present or absence of errors, whether or not discoverable, all to the greatest extent permissible under applicable law.
+    Affirmer disclaims responsibility for clearing rights of other persons that may apply to the Work or any use thereof, including without limitation any person's Copyright and Related Rights in the Work. Further, Affirmer disclaims responsibility for obtaining any necessary consents, permissions or other rights required for any use of the Work.
+    Affirmer understands and acknowledges that Creative Commons is not a party to this document and has no duty or obligation with respect to this CC0 or use of the Work.

+ *  Document-class: Continuation
+ *
+ *  Continuation objects are generated by Kernel#callcc,
+ *  after having +require+d <i>continuation</i>. They hold
+ *  a return address and execution context, allowing a nonlocal return
+ *  to the end of the #callcc block from anywhere within a
+ *  program. Continuations are somewhat analogous to a structured
+ *  version of C's <code>setjmp/longjmp</code> (although they contain
+ *  more state, so you might consider them closer to threads).
+ *
+ *  For instance:
+ *
+ *     require "continuation"
+ *     arr = [ "Freddie", "Herbie", "Ron", "Max", "Ringo" ]
+ *     callcc{|cc| $cc = cc}
+ *     puts(message = arr.shift)
+ *     $cc.call unless message =~ /Max/
+ *
+ *  <em>produces:</em>
+ *
+ *     Freddie
+ *     Herbie
+ *     Ron
+ *     Max
+ *
+ *  Also you can call callcc in other methods:
+ *
+ *     require "continuation"
+ *
+ *     def g
+ *       arr = [ "Freddie", "Herbie", "Ron", "Max", "Ringo" ]
+ *       cc = callcc { |cc| cc }
+ *       puts arr.shift
+ *       return cc, arr.size
+ *     end
+ *
+ *     def f
+ *       c, size = g
+ *       c.call(c) if size > 1
+ *     end
+ *
+ *     f
+ *
+ *  This (somewhat contrived) example allows the inner loop to abandon
+ *  processing early:
+ *
+ *     require "continuation"
+ *     callcc {|cont|
+ *       for i in 0..4
+ *         print "#{i}: "
+ *         for j in i*5...(i+1)*5
+ *           cont.call() if j == 17
+ *           printf "%3d", j
+ *         end
+ *       end
+ *     }
+ *     puts
+ *
+ *  <em>produces:</em>
+ *
+ *     0:   0  1  2  3  4
+ *     1:   5  6  7  8  9

+/*
+ *  Document-class: Fiber
+ *
+ *  Fibers are primitives for implementing light weight cooperative
+ *  concurrency in Ruby. Basically they are a means of creating code blocks
+ *  that can be paused and resumed, much like threads. The main difference
+ *  is that they are never preempted and that the scheduling must be done by
+ *  the programmer and not the VM.
+ *
+ *  As opposed to other stackless light weight concurrency models, each fiber
+ *  comes with a stack.  This enables the fiber to be paused from deeply
+ *  nested function calls within the fiber block.  See the ruby(1)
+ *  manpage to configure the size of the fiber stack(s).
+ *
+ *  When a fiber is created it will not run automatically. Rather it must
+ *  be explicitly asked to run using the Fiber#resume method.
+ *  The code running inside the fiber can give up control by calling
+ *  Fiber.yield in which case it yields control back to caller (the
+ *  caller of the Fiber#resume).
+ *
+ *  Upon yielding or termination the Fiber returns the value of the last
+ *  executed expression
+ *
+ *  For instance:
+ *
+ *    fiber = Fiber.new do
+ *      Fiber.yield 1
+ *      2
+ *    end
+ *
+ *    puts fiber.resume
+ *    puts fiber.resume
+ *    puts fiber.resume
+ *
+ *  <em>produces</em>
+ *
+ *    1
+ *    2
+ *    FiberError: dead fiber called
+ *
+ *  The Fiber#resume method accepts an arbitrary number of parameters,
+ *  if it is the first call to #resume then they will be passed as
+ *  block arguments. Otherwise they will be the return value of the
+ *  call to Fiber.yield
+ *
+ *  Example:
+ *
+ *    fiber = Fiber.new do |first|
+ *      second = Fiber.yield first + 2
+ *    end
+ *
+ *    puts fiber.resume 10
+ *    puts fiber.resume 1_000_000
+ *    puts fiber.resume "The fiber will be dead before I can cause trouble"
+ *
+ *  <em>produces</em>
+ *
+ *    12
+ *    1000000
+ *    FiberError: dead fiber called
+ *
+ *  == Non-blocking Fibers
+ *
+ *  Since Ruby 3.0, the concept of <em>non-blocking fiber</em> was introduced.
+ *  Non-blocking fiber, when reaching any potentially blocking operation (like
+ *  sleep, wait for another process, wait for I/O data to be ready), instead
+ *  of just freezing itself and all execution in the thread, yields control
+ *  to other fibers, and allows the <em>scheduler</em> to handle waiting and waking
+ *  (resuming) the fiber when it can proceed.
+ *
+ *  For Fiber to behave as non-blocking, it should be created in Fiber.new with
+ *  <tt>blocking: false</tt> (which is the default now), and Fiber.scheduler
+ *  should be set with Fiber.set_scheduler. If Fiber.scheduler is not set in
+ *  the current thread, blocking and non-blocking fiber's behavior is identical.
+ *
+ *  Ruby doesn't provide a scheduler class: it is expected to be implemented by
+ *  the user and correspond to Fiber::SchedulerInterface.
+ *
+ *  There is also Fiber.schedule method, which is expected to immediately perform
+ *  passed block in a non-blocking manner (but its actual implementation is up to
+ *  the scheduler).

+ *  fibers. See also the "Non-blocking fibers" section in Fiber class docs for explanations
+ *  of some concepts.
+ *
+ *  Scheduler's behavior and usage are expected to be as follows:
+ *
+ *  * When the execution in the non-blocking Fiber reaches some blocking operation (like
+ *    sleep, wait for a process, or a non-ready I/O), it calls some of the scheduler's
+ *    hook methods, listed below.
+ *  * Scheduler somehow registers what the current fiber is waited for, and yields control
+ *    to other fibers with Fiber.yield (so the fiber would be suspended while expecting its
+ *    wait to end, and other fibers in the same thread can perform)
+ *  * At the end of the current thread execution, the scheduler's method #close is called
+ *  * The scheduler runs into a wait loop, checking all the blocked fibers (which it has
+ *    registered on hook calls) and resuming them when the awaited resource is ready (I/O
+ *    ready, sleep time passed).
+ *
+ *  A typical implementation would probably rely for this closing loop on a gem like
+ *  EventMachine[https://github.com/eventmachine/eventmachine] or
+ *  Async[https://github.com/socketry/async].
+ *
+ *  This way concurrent execution will be achieved in a way that is transparent for every
+ *  individual Fiber's code.
+ *
+ *  Hook methods are:
+ *
+ *  * #io_wait
+ *  * #process_wait
+ *  * #kernel_sleep
+ *  * #block and #unblock
+ *  * (the list is expanded as Ruby developers make more methods having non-blocking calls)
+ *
+ *  When not specified otherwise, the hook implementations are mandatory: if they are not
+ *  implemented, the methods trying to call hook will fail. To provide backward compatibility,
+ *  in the future hooks will be optional (if they are not implemented, due to the scheduler
+ *  being created for the older Ruby version, the code which needs this hook will not fail,
+ *  and will just behave in a blocking fashion).
+ *
+ *  It is also strongly suggested that the scheduler implement the #fiber method, which is
+ *  delegated to by Fiber.schedule.
+ *
+ *  Sample _toy_ implementation of the scheduler can be found in Ruby's code, in
+ *  <tt>test/fiber/scheduler.rb</tt>

+ *  <code>[set]</code>::

+ *
+ *  <code> \ </code>::

-* How to compile and install on djgpp
-
-This is what you need to do to compile and install Ruby:
-
-  1. Run configure.bat, which will generate config.h and Makefile
-     and ext/extmk.rb(GNU sed required).
-     Message like this is normal:
-       sed.exe: can't read 123456789: No such file or directory (ENOENT)
-
-  2. Edit defines.h if you need.  Probably this step will not need.
-
-  3. Remove comment mark(#) before the module names from ext/Setup.dj (or
-     add module names if not present).
-
-  4. Run make.
-
-  5. Optionally, run 'make test' to check whether the compiled Ruby
-     interpreter works well.  If you see the message "test succeeded",
-     your ruby works as it should (hopefully).
-
-  6. Run 'make install'

+Fri Oct 14 13:22:18 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* version 0.52: ……なんてこったい.
+
+	* eval.c(rb_call): returnの処理が間違っていたので, マシンによって
+	  はreturnで関数を終了するだけでなくtoplevelまでつき抜けていた.
+
+	* object.c: Builtinクラスを新設. 組み込み関数をKernelから移した.
+	  nilが組み込み関数を理解するとトラブルの元である.
+
+	* dbm.c: Dictと同様にeachが[key,value]を返すように.
+
+	* version 0.51
+
+Thu Oct 13 12:13:48 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* eval.c(SETUP_ARGS): 付加演算子が配列でない時には配列に変換する.
+
+	* parse.y: 括弧なしのメソッド呼び出しでも`*'による付加引数が使える
+	  ようにした. ただし, 通常引数が一つもない場合は乗算演算子と区別が
+	  つかないので, 必ず括弧が必要.
+
+Wed Oct 12 10:09:07 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* eval.c(rb_call): キャッシュの計算をinline化. キャッシュミスがあ
+	  れば関数呼び出しでメソッドを検索する. methods.cはなくなった.
+
+	* eval.c(rb_eval): ローカル変数用の領域をalloca()するように変更.
+	  サイズの変更が必要になれば改めてmalloc()するように.
+
+	* parse.y: error recoveryの際にlex_stateを更新しておくように.
+
+Tue Oct 11 17:10:46 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* socket.c(for_fd): ファイル記述子(Fixnum)からソケットインスタンス
+	  を得るメソッド. たとえばinetdから起動されたサーバで標準入出力に
+	  ソケット操作を行なうために使う. つまりSocket.for_fd($stdin)で標
+	  準入力に対応するソケットオブジェクトが得られる.
+
+	* io.c(to_i): IOクラスのインスタンスを整数に変換するとそのファイル
+	  記述子を返すように.
+
+	* numeric.c(num2int): to_iメソッドを使ってできる限り整数に変換する.
+	  以前はnum2fixだけが全てのオブジェクトに対してto_iメソッドを適用
+	  していた.
+
+	* sprintf.c(Fsprintf): 整数表示の際, オブジェクトをできる限り整数
+	  に変換するように(to_iメソッドを使う).
+
+Fri Oct  7 14:06:32 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* eval.c(Fcaller): 必要性がよく分からないのでドキュメントから削除.
+	  将来デバッガを作る時に復活させよう.
+
+	* eval.c(rb_call): Cで記述されたメソッド呼び出しでは環境をスタック
+	  にセーブしないことによって高速化.
+
+Wed Oct  5 15:00:58 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* ruby.h: 一時env.hに移動してたQselfの定義を復活. ただし今回は関数
+	  として実現(env.hでは変数として再定義してある).
+
+	* ruby.h: TRUEでsyntax errorにならないよう#undefを追加.
+
+	* eval.c(rb_eval): thread化に挑戦したが, 失敗(速くならなかった).
+	  が, Scopingなどの無駄なコードの削除とメソッド呼び出しの引数セッ
+	  トのinline化で若干の高速化を実現した. 副作用として, argc, argv形
+	  式の関数呼び出しの仕様が変化した(argvにselfを含まなくなった).
+
+	* eval.c(rb_call): メソッド呼び出しの高速化.
+
+Tue Oct  4 11:40:53 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* ruby-mode.el: 修飾子に対応した.
+
+	* parse.y: 多重代入にrestをつけた. この機能を使えばoptional引数の
+	  解析が簡単にできる(はず).
+
+	* pack.c(unpack): uuencode形式のdecodeの際に文字列の長さが間違って
+	  いた.
+
+Mon Oct  3 15:58:41 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* file.c(type): ファイルタイプを文字列で返すメソッド.
+
+Fri Sep 30 11:36:07 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* object.c: デフォルトの真の値である%TRUEの値を1(Fixnum)からtに変
+	  更した. to_sで文字列に変換した時にも`t'と表示される. 更に踏み込
+	  んで`t'を予約語にしてlispのようにしようかとも思ったが, そこまで
+	  は決心できなかった. 一文字のローカル変数はかなり使いそうな気がす
+	  るので….
+
+	* array.c,dict.c: equalを再定義しているクラスで, hashを正しく定義
+	  した.
+
+Wed Sep 28 23:30:28 1994  Yukihiro Matsumoto  (matz@dyna)
+
+	* eval.c(Ffail): 今までfailはカーネルクラスのメソッドであったが,
+	  構文に組み込んだ. この変更によって, 1)`fail'は予約語となり, ロー
+	  カル変数に用いることができなくなった. 2)`fail'単体で例外を発生す
+	  るようになった. 3)failはメソッドではなくなったので再定義される可
+	  能性がなくなった.
+
+	* dic.c, dbm.c(indexes): Arrayのindexesと同様の機能を持つメソッド
+	  を追加.
+
+	* array.c(indexes): 引数をインデックスとする要素の配列を返す. 整数
+	  の配列を引数とする時には引数の要素をインデックスとする要素の配列
+	  を返す.
+
+Mon Sep 19 13:42:31 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* array.c(aset): 部分配列に対する代入で配列以外のオブジェクトが指
+	  定された場合に多重代入と同じルールで配列化するようにした.
+
+	* io.c(print): 引数として与えられた各オブジェクトにprint_onメッセー
+	  ジを与えるように. 実行速度は落ちるが柔軟性は増す.
+
+Fri Sep 16 14:59:18 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* glob.c: ワイルドカードの導入. bashに使われているGNUのglobルーチ
+	  ンを流用した.
+
+Mon Sep 12 18:36:58 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* parse.y(value_expr): 式がnilの時に対応.
+
+	* class.c: ICLASSのclassが必ずClass/Moduleを指すように.
+
+Tue Sep  6 16:23:28 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* re.c:	正規表現内で「\数字」形式が指定できるように.
+
+	* parse.y:「do expr using var ... end」形式はなくなった. 寂しい気
+	  もする. *BACKWARD INCOMPATIBILITY*
+
+Mon Sep  5 10:59:01 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* numeric.c(next): Numericクラスにもnextを提供.
+
+	* string.c(upto): uptoを提供.
+
+	* range.c(each): nextを使ったインタフェースからuptoを使うように変
+	  更した. この方が一つのメソッドで処理をまとめで行なうことができる.
+
+Fri Sep  2 15:25:39 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* dict.c(each): 戻り値を[key, value]のペアに変更. 今までのeachは
+	  each_valueとして残る. *BACKWARD INCOMPATIBILITY*
+
+Thu Sep  1 10:49:04 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* 成功した(特別な戻り値を持たない)システムコールは`0'を返すように.
+
+Wed Aug 31 00:26:51 1994  Yukihiro Matsumoto  (matz@dyna)
+
+	* string.c: チェックサムを得るメソッド`sum'を作った.
+
+	* class.c(include_class_new): ICLASSのclassをもとのクラスにした.
+	  gcの際に元クラスをマークする必要があるのが, フィールドを増やす余
+	  地が無いので, classフィールドを流用した. 私の見積りが間違ってい
+	  て, ICLASSのインスタンスにメッセージを送る事があれば, おかしな動
+	  作をするだろう.
+
+	* eval.c(masign): 式(a,b = nil)の値を[nil]からnilに変更した.
+
+Mon Aug 29 11:56:09 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* class.c: rb_define_mfuncを無くして, メタクラスにモジュールをイン
+	  クルードするようにした.
+
+	* error.c(yyerror): 同じ行で複数のsyntax errorをリポートしないよう
+	  にした.
+
+	* file.c: FileTestモジュールにファイルテストメソッドを分離した.
+
+	* parse.y: 演算子を指定する時のlex_stateを正しく設定した.
+
+Sat Aug 27 01:23:34 1994  Yukihiro Matsumoto  (matz@dyna)
+
+	* parse.y: if/whileなどの複合式をprimaryに移動した. これによって例
+	  えば「if cond then a else b end.message()」のような式が書けるよ
+	  うになった.
+
+Fri Aug 26 10:46:30 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* spec: 整理された文法にしたがって書き直した.
+
+	* parse.y: ここ数日で混乱していた文法を整理した. 括弧を省略したメ
+	  ソッド呼び出しができるようになったこと, modifierが付けられるよう
+	  になったこと, returnにリストが渡せるようになったことが主な変更点
+	  である.
+
+	* process周りが怪しいがとにかくSolaris 2.3で動くように.
+
+	* parse.y: 曖昧性がない場合にはメソッド呼び出しの引数の括弧を省略
+	  できるように. 省略できるメソッド呼び出しの条件は, 1)かならず1個
+	  以上の引数を必要とすること, 2)第1引数が`+', `-', `(', `[', `{',
+	  `/'など, 式の始まりに置かれた時と途中に現れた時とで解釈が違う記
+	  号で始まらないこと, である.
+
+Thu Aug 25 13:54:58 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* parse.y(cond): 条件式の展開部にbugがあった.
+
+Wed Aug 24 00:01:15 1994  Yukihiro Matsumoto  (matz@dyna)
+
+	* parse.y: returnはコンマで区切ったリストも受け取るように. つまり,
+	  return a, b, cはreturn [a, b, c]と同じ意味になる.
+
+	* parse.y: yield以外の大域脱出制御式をexprからexpr0に移した. よっ
+	  てメソッドの引数に制御式を使えなくなる(これで困る人はいないはず).
+
+	* parse.y: `+'の定数展開の際に演算子の優先順位を忘れていた.
+
+	* eval.c: untilの戻り値はnilになった.
+
+	* parse.y: modifierとしてのif/unless/while/untilを追加.
+
+	* parse.y: 文法からendの後ろにつけるキーワードを削除. ほとんど使わ
+	  なかった上に, emacsではruby-modeがあれば対応のチェックが機械的に
+	  出来るため.
+
+Tue Aug 23 18:08:33 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* eval.c: スクリプト実行開始前に例外が発生した時にcore dumpした.
+	  組み込み用にコードを変更した時にenbugしてしまった.
+
+Tue Aug 23 00:07:17 1994  Yukihiro Matsumoto  (matz@dyna)
+
+	* eval.c: doの戻り値がいつもnilになっていた.
+
+	* parse.y: loop制御変数の多重代入化にbugがあった.
+
+	* parse.y(expand_op): 文字列も畳み込みの対象に.
+
+Mon Aug 22 10:50:01 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* parse.y(expand_op): `+'に関しては結合則を使って, より多く定数畳
+	  み込みを行なうように.
+
+	* ruby.c(proc_options): argcが0の時にも対応.
+
+	* parse.y: forなどの制御変数に多重代入も使えるように.
+
+Sat Aug 20 00:59:40 1994  Yukihiro Matsumoto  (matz@dyna)
+
+	* parse.y(call_op): 演算子`~'の取り扱いをルール部へ移動.
+
+Fri Aug 19 11:44:13 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* main.c: rubyをほかのプログラムに組み込めるようにmain()を分割した.
+	  それにともない, プログラムの呼び出し構造を修正した.
+
+	* parse.y: 条件式の定義を変更. ifなどの条件式の中でだけ`&&'や`||'
+	  および`!'の引数が条件式になるように. この変更により条件式以外の
+	  場所での `&&', `||', `!'演算子の動作が直観に一致する.
+
+	* parse.y: 実引数の`*'の後に続く引数はexprに制限した. 今までは全て
+	  の文が有効であったが, ここで定義文があってもしょうがない.
+
+Thu Aug 18 10:21:45 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* re.c: 正規表現ルーチンの初期化部分を削除してしまっていた. これで
+	  はemacsの正規表現になってしまう.
+
+	* version.c: copyright表示を追加.
+
+	* version.c: バージョン表示をstderrに.
+
+	* configure.in: gccがない場合testに失敗していた.
+
+Fri Aug 12 14:12:23 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* array.c(astore): 配列の拡大する時にある程度の大きさをまとめて拡
+	  大するように.
+
+	* io.c(Fprint): 配列に対しては一度文字列に変換することなく, 直接内
+	  容を出力するように.
+
+	* string.c(str_new): memmoveからmemcpyへ置き換えた. これでもかなり
+	  速度が違う.
+
+	* ruby.h: データメンバの取り出しで名前を文字列からIDで指定するよう
+	  にした. かなりの高速化になる.
+
+	* io.c: $ARGFという変数で引数列からなる仮想ファイルをオブジェクト
+	  として扱えるようにした. 今まではトップレベルのgets()などを使って
+	  アクセスしていたが, どうもオブジェクト指向的ではなかった.
+
+Thu Aug 11 11:43:15 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* gc.c: mark_location()の間違った呼び出し方の行が残っていた.
+
+	* method.c: プロトタイプ宣言が足りなかった.
+
+Wed Aug 10 15:54:46 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* variable.c: -vオプションが指定されている時は初期化されていない,
+	  大域変数, インスタンス変数, ローカル変数を参照した時点でwarning
+	  を出すようにした.
+
+Tue Aug  9 11:50:48 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* bignum.c: 冪乗に関しても多倍長演算を行なうように. 特に浮動小数点
+	  数の範囲を越えた時の処理を的確に行なうように.
+
+	* eval.c: メソッド定義後は構文木から, メソッド定義部分を外す. 無駄
+	  な再定義が起こらないようにするためと2重にfree()されないため.
+
+	* array.c(Fary_aref): 引数が1つでFixnumの時, Range checkを行なわな
+	  いように修正.
+
+	* eval.c: メソッドの引数の数をコンパイル時に計算して若干の高速化.
+
+Mon Aug  8 13:06:24 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* object.c: nilによる比較連鎖をなくした.
+
+	* parse.y: bit演算子の優先順位を比較演算子よりも強くした.  Cとは異
+	  なることになるが, 直観には合致する.
+
+	* gc.c: クラスを解放する時, 個々のメソッド毎にキャッシュをクリアす
+	  るのではなく, クラス単位でクリアするように.
+
+Thu Aug  4 18:45:09 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* methods.c(method_free): 解放されたメソッドに関してキャッシュをク
+	  リアしておく必要があった.
+
+	* gc.c: Dataクラスのデータ部分をfree()し忘れていた.
+
+Wed Aug  3 09:58:14 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* parse.y: def func .. end形式による関数メソッドの定義はなくなった.
+
+	* methods.c: func形式のメソッドをなくした. あっても, あまり意味が
+	  ないので.
+
+	* eval.c: $0への代入でps(1)の出力が変化するように.
+
+	* io.c(Fsyscall): syscall()を実現.
+
+Mon Aug  1 13:41:11 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* parse.y: ダブルクォートで囲まれた文字列や正規表現中で"#{変数名}"
+	  または"#変数名"という形式で変数の内容を埋め込むことができるよう
+	  になった.
+
+	* io.c: 関数メソッドsystem2()はなくなった. 今はバッククォートがあ
+	  るからね.
+
+	* parse.y: `cmd`によってコマンドを文字列に展開することができるよう
+	  になった.
+
+	* parse.y: __FILE__, __LINE__を追加. それぞれファイル名(文字列),
+	  行番号(整数)を値とする疑似変数.
+
+Fri Jul 29 13:16:07 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* methods.h: メソッドをオブジェクトとして扱うのをやめる. メソッド
+	  のメモリ管理にはリファレンスカウントを使うことにした. これでオブ
+	  ジェクトの数が減ってほんの少しだけGCが速くなる(かな).
+
+	* purifyによってメモリ関係のバグを検査した(見つかる,見つかる…).
+
+	* gc.c: GCをプログラマが変数をマークする形式から, スタックとレジス
+	  タからマークする方法に変更. 移植性が下がるような気もするが, siod
+	  やscmでも採用されているから多分大丈夫だろう. Linux on i486でも動
+	  作を確認した.
+
+Wed Jul 27 16:13:13 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* eval.c(Eval): トップレベルでは構造木をfreeしないように. どうせ解
+	  放されるから時間の無駄である.
+
+	* array.c, dict.c: "=="を構造一致に変更.
+
+Fri Jul 22 10:14:09 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* error.c: 組み込みタイプの名前を登録し忘れていた.
+
+Thu Jul 21 14:06:48 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* parse.y(freenode),eval.c(Eval): 解析木を解放し忘れていた.
+
+Mon Jul 18 10:19:15 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* parse.y: 多重代入を処理するルールにバグがあって, 3要素以上の多重
+	  代入に失敗していた.
+
+	* eval.c(rb_eval): 多重代入で, 右辺が配列でない時には`to_a'メソッ
+	  ドで配列に変換して代入するようにした. 今までの仕様だと右辺値が第
+	  1要素にそのまま代入されていたが, structなど配列に変換できるもの
+	  は変換した方が嬉しい気がする.
+
+	* dbm.c,dict.c(delete_if): メソッド追加.
+
+	* process.c(wait,waitpid): システムコールwaitpidまたはwait4がある
+	  時はそちらを使うように. configureもそれらをチェックするように変更.
+
+	* dbm.c, dict.c(clear): メソッド追加.
+
+Fri Jul 15 10:54:45 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* array.c(Fary_fill,Fary_clear): メソッドを追加.
+
+	* string.c(Fstr_split): $;の値が長さ1の文字列である時, これを正規
+	  表現化しないで, 単なる文字として分割する.
+
+	* string.c(Fstr_aset/Fstr_aref): インデックスが文字列の範囲外だっ
+	  た時の動作をArrayを参考に修正した.
+
+	* array.c(astore,Fary_aset): 領域をreallocした後, ゼロでクリアする
+	  ように. 今まで配列にゴミが入っていた.
+
+	* array.c: []/[]=でのインデックス関係を整理. 基本的に負のインデッ
+	  クスに代入しない限り例外は起きないように変更した. 必要に応じて適
+	  当に解釈して, 必要ならば領域を拡張するように.
+
+Thu Jul 14 11:18:07 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* autoexec.c: 削除. autoload関係の機能は今後検討しよう.
+
+	* dict.c: 辞書クラスの正式名称をDictに変更した. 別名としてHashを用
+	  意した. 今までDictionaryなどと長い名前にしていたが誰も使っていな
+	  かったしね. *BACKWARD INCOMPATIBILITY*
+
+	* parse.y: Dictを生成する構文を追加. こちらを{..}にした.
+
+	* parse.y: 配列を生成する構文を[..]に変更した. 過去のRubyスクリプ
+	  トとの互換性が保てないが, Dictを生成する構文を導入するに当たり,
+	  perl5に合わせて(意識して), 変更する時期は今しかないと考えた.
+	  *BACKWARD INCOMPATIBILITY*
+
+	* eval.c(Feval): eval()でメソッドを定義する時, 定義されるクラスを
+	  メソッドの所属するクラスにした. 今まではObjectクラスに定義されて
+	  いた.
+
+	* parse.y: ローカル引数がない時のeval()で落ちていた.
+
+Tue Jul 12 09:41:28 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* pack.c: uuencode形式のサポート.
+
+	* `-0'を`-R'に. 出力レコードセパレータをコマンドラインから指定する
+	  方法はなくなった. どうも, 仕様がゆれるなあ.
+
+Mon Jul 11 09:51:24 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* ruby.c: `-r'オプションは`-0'オプションになった. 当面は`-r'も有効
+	  だが変更される可能性がある. `-R'は当面はそのまま.
+
+	* version.c: version表示に日付を含めた.
+
+	* parse.y: private methodの復活. RubyのprivateメソッドはC++におけ
+	  るprotected methodに該当するもので, `@'で始まる名前を持つ.
+
+	* env.h: struct ENVIRONの定義を分離.
+
+	* parse.y: `\$var', `\@var', `%var'も許すように.
+
+	* variable.c(Fdefined): idも引数として受け付けるように.
+
+	* parse.y: if文/unless文にキーワードthenを追加. thenなしというのは,
+	  意外と間違いが多いので. もちろん省略できる.
+
+Sat Jul  9 02:16:04 1994  Yukihiro Matsumoto  (matz@dyna)
+
+	* eval.c(rb_eval): class/moduleの評価で新しいスコープを割り当てて
+	  いなかった. スコープ割り当て部分をrb_call()からrb_eval()に移した.
+
+	* eval.c(rb_call): realloc()に渡される事のある, ローカル変数用の領
+	  域をalloca()していた. たまに落ちるわけだ.
+
+	* string.c(Fstr_times): 割り当てた領域を越えた部分を変更していた.
+
+Wed Jul  6 15:52:42 1994  Yukihiro Matsumoto  (matz@ix-02)
+

+
+	* string.c(ucfirst,lcfirst): 最初の1文字だけの大文字/小文字変換.
+
+	* numeric.c(chr): 整数の文字列化メソッド.
+
+	* inits.c, dbm.c: DBMが使えない時はクラスそのものを定義しないよう
+	  にした.  利用できないクラスはnilとすることを今後のポリシーとしよ
+	  う(いままではアクセスした時点でエラーが発生していた). autoexec()
+	  のあり方も検討が必要になりそうだ.
+
+	* bignum.c(bigadd): バグ修正.
+
+Thu Jul  7 11:12:18 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* eval.c(Fload,Feval): eval_treeをクリアし忘れていた.

+Tue Jul  5 12:48:39 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* io.c(Feof): 追加. コマンドラインからなる仮想ファイルについても
+	  EOFが検出できるように.
+
+	* ruby.c: -l/-r/-R/-Xオプションの追加.
+
+	* ruby.c: -n/-pオプションのloopの付加などをメインルーチンに移動し
+	  た. これで, オプションの解析途中で(`-c'オプションのせいで)終了な
+	  どといったことはない.
+
+	* io.c(Fgets): 高速化. 凝ったことをしない方が速かった. 虚しい.
+
+Mon Jul  4 15:55:48 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* Socket:getsockname/getpeername - ようやく仕様が安定した.
+
+	* io.c(Fgets): eachでgetsを記述するのではなく, getsでeachを記述す
+	  るようにした.
+
+Fri Jul  1 10:35:49 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* $ENV[env] = nil/$ENV.delete(env)で環境変数を削除できるようになっ
+	  た. $ENV.deleteは環境変数の以前の値を返す.
+
+	* !~の定義が間違っていた.
+
+	* Dict,DBM:[]= - nilの代入によって要素を削除できるようになった. こ
+	  れにともないnilはDictの要素になれなくなった.
+
+	* ソースの整理. 盲腸のような使われていないコードをなくしたり, 変数
+	  名を付け変えたりした.
+
+Fri Jul  1 00:21:29 1994  Yukihiro Matsumoto  (matz@dyna)
+
+	* Array:join() - 要素数0の配列に対して空文字列を返す.
+
+	* RawSocket:open(),socketpair() - 文字列で指定できるドメインとタイ
+	  プをいくつか追加した.
+
+Thu Jun 30 13:51:29 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* -fオプションをなくした. 昔(loadのなかった頃)の名残なので, 今となっ
+	  ては必要ないだろう.
+
+	* -sオプションを追加. perlの-sオプションと同じ動きをする.
+
+	* RawSocketクラスを提供する. Socketに対するシステムコールレベルの
+	  アクセスが可能になった.
+
+Thu Jun 30 00:27:19 1994  Yukihiro Matsumoto  (matz@dyna)
+
+	* Socket - bug fixes.
+
+	* linuxではsyscall(SYS_select)が正常に動作しない.
+
+	* Socket:addr,peeraddr - 配列としてsockaddrの情報を返す.
+
+Wed Jun 29 00:14:20 1994  Yukihiro Matsumoto  (matz@dyna)
+
+	* Socket:setopt,getopt - setsockopt(2), getsockopt(2)へのアクセス
+	  を実現.
+
+	* sprintf() - rubyにはunsignedは無いので, %uを取り除いた.
+
+	* sprintf() - %b, %x, %oでは2の補数表現, %B, %X, %Oでは符号付き表
+	  現で出力するように. ここ数日でsprintf()の仕様がゆらいでいたが,
+	  これで落ち着きそうだ.
+
+Tue Jun 28 14:42:03 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* Bignum:<<,>> - 2の補数をとる処理を除いた. シフト演算には関係ない
+	  処理だった.
+
+	* Bignum:^ - bug fix. 符合が反対だった.
+
+	* sprintf() - 2進出力子"%b"を追加.
+
+	* sprintf() - %x, %oでFixnumを出力する時, 2の補数表示を行なわない.
+
+	* sprintf() - %x, %oはやはり負の数の時は`-'を出力するように.
+
+Mon Jun 27 14:56:13 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* sprintf() - Bignumについても%d, %oは(2の補数表現に変換して)正の
+	  整数を表示するようにした.
+
+	* Bignumに対する論理演算の定義を修正した. 負の数は2の補数表現であ
+	  るとみなし, かつ仮想的に左側に無限に1が連続しているような演算結
+	  果を得る.
+
+	* Fixnum:<<,>> - 符合付シフトに変更.
+
+	* Bignum:>> - 負の整数のシフトに対応した.
+
+	* __END__, ^D, ^Zでスクリプトを終了できる.
+
+	* -xオプションを追加. #! ..rubyなる行まで読み飛ばす.
+
+	* -cオプションを追加. コンパイルのみを行う.
+
+Sat Jun 25 01:37:21 1994  Yukihiro Matsumoto  (matz@dyna)
+
+	* Fixnum:<< - 必要に応じてBignumに拡張して左シフトするように. よっ
+	  て, シフト幅が32を越えるとCやPerlとは違った値を返す.
+
+Fri Jun 24 10:01:28 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* ioctl()/fcntl() - システムコールを呼び出す前にバッファの大きさを
+	  調節するようにした.
+
+	* String:toupper/tolower - 文字列を置き換えたコピーを作るのではな
+	  く, 元の文字列の内容を変更するようにした.
+
+	* inplace editを実現した. perlと同じように`-i'オプションで指定する.
+	  もっとも, こちらはMS-DOSのこととか考えてないけど.
+
+	* デフォルトの出力先を追加した. 今までは$stdoutに代入するしか方法
+	  はなかった.
+
+Fri Jun 17 10:55:08 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* 環境変数にアクセスする方法としてgetenv()/setenv()以外に$ENVを用
+	  意した. $ENVは文字列-文字列の辞書であるかのように動作するEnvDict
+	  オブジェクトが代入されている(eachはassocを与える).
+
+	* nilに代入するとcore dumpした. コンパイル時のチェックを強化.
+
+	* Struct: struct_new()の引数をGCプロテクトする必要がある. せめてス
+	  タック領域だけでもスキャンできるようにしなければいけないんだろう
+	  か? でも, 移植性がなあ.
+
+Fri Jun 17 01:01:46 1994  Yukihiro Matsumoto  (matz@dyna)
+
+	* Time::asctime() - 日付のフォーマットで日が落ちていた.
+
+	* Stat: StatはEtcなどと同様にStructで実現したので, Statクラスは無
+	  くなった.
+
+Thu Jun 16 10:32:23 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* bignum.c: いくつかのバグを修正した. Fixnumを渡すべきところで普通
+	  のintを渡していた. 失敗.
+
+	* big2str() - 1桁ずつbaseで割る代わりに, 4桁ずつ割算を行なうように
+	  した. これで多倍長割算の回数が1/4になる. さらに整数->数(文字)へ
+	  の変換をテーブルを用いるようにした.
+
+	* rb_ivar_get_1() - すでに何らかのインスタンス変数を持つオブジェク
+	  トでは, 未定義のインスタンス変数の値が不定値になっていた.
+
+	* yylex() - インスタンス変数の認識に失敗していた. attr()は正しく動
+	  作していたので, 混用すると動作しなかった. 全部違っていたから動い
+	  ていたのね.
+
+	* Object:attr() - すでにアクセスメソッドが定義されている時にはデフォ
+	  ルトのアクセスメソッドを定義しないようにした. もっともアクセスメ
+	  ソッドと同名のメソッドの区別はRubyには存在しないけど, それは仕方
+	  がないよね.
+
+	* pack.c: エンディアンをautoconfで判定するようにしたので, v/Vが使
+	  えるようになった. またntoh?()/hton?()も自前で用意した.
+
+	* Stat: st_rdevをアクセスするメソッドを追加. さらにシステムがstat
+	  構造体にst_blksize, st_blockを持っているかをautoconfでチェックす
+	  るようにした.
+
+	* ドキュメントを少し整備した.
+
+	* INT2FIX()のうち, 31bit幅が保証できないものは, int2inum()に置き換
+	  えた.
+
+Wed Jun 15 10:18:27 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* sprintf() - bignumの出力の時, 出力幅を正しく計算するようにした.
+
+	* str2inum() - baseが0の時, baseを自動判定するように(0xで始まる時
+	  16 進, 0で始まる時8進).
+
+Tue Jun 14 16:08:42 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* gc.c: Bignum型を追加するのを忘れていた. 組み込み型を追加した時に
+	  は必ずmark()とsweep()にその型に関する処理を追加する必要がある.
+
+	* bignum: 割算も動いたような気がする. アルゴリズムを理解していない
+	  ので, 自信がない.
+
+Mon Jun 13 14:36:55 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* まだサポートしていないメソッドなどがあるが, 曲がりなりにもBignum
+	  が使えるようになる. これでioctlも使える.
+
+Fri Jun 10 17:26:42 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* Comparable: 基礎となるメソッドを`=='と`>'から`<=>'に変更した. 今
+	  後Comparableのサブクラスは`<=>'だけを再定義する必要がある.
+
+Wed Jun  8 13:12:18 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* Need_Fixnum()をほとんどなくして, NUM2INT()で直接intに変換するこ
+	  とにした. これで31bitに丸めて桁落ちをおこす問題がなくなる.
+
+Tue Jun  7 09:45:31 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* ruby.h: マクロFIXABLE(n)を追加. ついでにFIXNUM周りの定義を変更し
+	  て, 移植性を高めた(つもり).
+
+	* C++の予約語であるnewを削除した. しかし, もうひとつの予約語である
+	  classに関しては, 置き換える単語が思いつかないこともあってそのま
+	  まになっている.
+
+	* 31bitを越えそうなINT2FIX()を関数呼び出しに変えた. 将来bignumが導
+	  入された時には自動的にbignumを返すようにする.
+
+	* readline() - 引数の`-'は標準入力を意味するようになった.
+
+	* ruby.h: 右シフトが論理シフトか算術シフトかは処理系依存のようなの
+	  で, ruby.hでcppを使ってチェックするようにした. これでうまくいく
+	  と思うのだが, 手元に符合付intを論理シフトする処理系がないので確
+	  認できない. NEWS-OSのCCは確か右シフトはいつも論理シフトだったよ
+	  うな気がするんだけど….
+
+Mon Jun  6 10:10:22 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* FIX2INT()の定義を変更した. どうして昔はうまく動かなかったんだろ
+	  うか? もしかして, 右シフトの符号拡張は処理系依存?
+
+	* FIX2INT()とFIX2UINT()を使い分けるようにした. もっともfixnumは31
+	  ビットしかないので, 本質的な解決にはならないのだが(ioctlが組み込
+	  みたかった).
+
+	* printを関数的メソッドから通常メソッドに変更. 引数が与えられない
+	  時にはレシーバをプリントするようにした. これでprintをメッセージ
+	  形式でも実行できるようになった. 例:
+
+		ruby -e 'readlines().sort.print'
+
+	  上のスクリプトは, 引数として与えられた(あるいは標準入力から読み
+	  込まれた)文字列を各行毎にソートして表示する.
+
+	* eval.c: argc,argvパターンで引数を受けるメソッドに引数が一つも与
+	  えられない時, argvがnilになっていた(argv[0]にアクセスすると落ち
+	  てしまう).
+
+	* _exit()を追加. こちらは例外処理など行なわない.
+
+	* dbmクラス: クラス名称をDBM(大文字)に統一した.
+
+Sat Jun  4 00:51:04 1994  Yukihiro Matsumoto  (matz@dyna)
+
+	* ループ変数にも属性や配列要素を指定できるようにした.
+
+Fri Jun  3 09:49:48 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* 多重代入において, 属性代入, 配列要素への代入も行なえるようにした.
+
+	* Need_Fixnum(): nilを0に変換するように.
+
+	* Enumerable:min, max, index, includes - 追加. min, maxは要素が
+	  `<=>'メソッドを持つことを仮定している.
+
+	* Dict/Dbm:length - 要素数を返すメソッド.
+
+	* Dbmクラスにto_aメソッドを追加.
+
+	* Sunにおけるsortの誤動作の件, 昨日の修正でfixされた. しかし, それ
+	  でなぜ動かなかったのかは明らかではないが…. 比較関数がどんな値を
+	  返しても指定した領域外をアクセスするのはバグではないか.
+
+	* ファイルの全内容を読んで, 各行を配列として返すメソッドはpythonを
+	  参考にして`readlines'という名前にした. それにともないgetsに対し
+	  てreadlineという別名を用意した.
+
+Fri Jun  3 00:08:38 1994  Yukihiro Matsumoto  (matz@dyna)
+
+	* Array:sort - 判別関数の戻り値はFixnumではなく, Intであるべきだっ
+	  た. 間違い. Sunで動作がおかしかったのはこのせいかも知れない.
+
+Thu Jun  2 11:48:37 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* IO:read_all() - ストリームの最後まで入力して, 各行を要素とする配
+	  列を返すメソッドを追加. また関数メソッド read_all()も追加した.
+  	  これは引数のファイルから読み込んで各行を要素とする配列を返す. 意
+	  味的には
+
+		def read_all()
+	  	  ary = {}
+	  	  while gets()
+		    ary.push($_)
+		  end
+		end
+
+	  とほぼ等価である.
+
+	* String:atoiメソッドを削除. to_aメソッドからaが配列であるとの連想
+	  を呼んで, 混乱を招かないため. 代わりにto_iメソッドを使うこと.
+
+	* 配列への変換メソッドto_aを導入した. 通常のオブジェクトは自分自身
+	  を唯一の要素とする長さ1の配列を返す. 配列は自分自身を, 辞書はキー
+	  と値のペアの配列を返す. Enumeratedをincludeしたクラスは, eachが
+	  返す各要素を含む配列を返す.
+
+	* file.c: 不定個の引数を受けとるメソッド(chmod,chown,utimes)を書き
+	  換えて, 整理した. それに伴い, 最初に全ての引数の型チェックを行な
+	  うようにした. 型チェックに失敗すると処理を行なわずに例外を発生さ
+	  せる.
+
+	* configure.in: 不必要なテストを行なわないように修正した.
+
+Tue May 31 10:41:08 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* String:pack(): 2進数の文字列変換(B,b)で0と1が逆だった.
+
+	* Math.c: 実数系のメソッドに引数として整数が渡された時に自動的に変
+	  換するようにした.
+
+	* toupper(), tolower(): 文字列の判定ミスで変換されていなかった.
+
+	* getopt_long()の仕様によって, スクリプトへの引数がインタプリタの
+	  引数だと解釈されていた. 引数パターン文字列の先頭に`+'を追加.
+
+	* config.hを削除した. DEFINEはMakefileで与えられる.
+
+	* sprintf(): "%d"に文字列が与えられた時にはアドレスではなく内容を
+	  整数に変換するようにした. ついでに浮動小数点数も変換するように変
+	  更した.
+
+	* regexp.c: rubyの拡張正規表現(\d, \D, \s, \S)の処理で割り当てた領
+	  域を越えてバッファに書き込んでいた. 処理前にバッファをきちんと拡
+	  張するようにした. これで昨日問題にしていたメモリの問題は解決でき
+	  たと思う.
+
+	* yylex(): ダブルクォート文字列中でダブルクォートを表現するため
+	  のバックスラッシュ表現ができなかった.
+
+Mon May 30 10:07:42 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* 演算子`!'の右辺も条件式であるとした. これによって, この演算子を
+	  再定義する人は混乱するかも知れないが, 大多数のこの演算子を使う人
+	  は混乱を避けることができると思う.
+
+	* autoconfを使って, 自動的にMakefile, config.hを生成するようにした.
+	  これで, 多くのマシンでは`configure'を実行した後, `make'一発でコ
+	  ンパイルできると思う.
+
+	* clone: サブクラスに対して用いられた場合, 元のオブジェクトと同じ
+	  クラスのインスタンスを返すように(以前はビルトインクラスの場合を
+	  考えてなかった).
+
+	* ビルトインクラスのサブクラスも作れるように, リテラルのあるクラス
+	  にもnewメソッドを追加した.
+
+	* malloc()で落ちる. purifyが必要かも知れない.
+
+	* re.c: rb_global_variable()の呼びだし形式の間違い. 変数へのポイン
+	  タを渡さなければいけない.
+
+	* parse.y: ローカル変数の扱いに引数の評価順に依存する移植性のない
+	  部分があった.
+
+	* attr(): 属性設定のバグを直した. いつ内部仕様が変わったんだろう…?
+
+Sat May 28 23:08:18 1994  Yukihiro Matsumoto  (matz@dyna)
+
+	* 正規表現キャッシュの文字列一致判定をポインタ一致から内容一致に変
+	  更した. そういえば文字列リテラルは一回毎に新しくオブジェクトが生
+	  成されるのだった.
+
+Fri May 27 11:42:00 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* trから文字削除(delete), 文字圧縮(squeeze)を分離した. それにとも
+	  ないtrのオプション引数はなくなった.
+
+Thu May 26 10:32:55 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* スクリプト読み込みルーチンを書き直して, 通常ファイル以外のファイ
+	  ル名や空文字列がスクリプトとして与えられた場合に対応した. また,
+	  標準入力からスクリプトを読み込む時に, 一時ファイルが/tmpに残らな
+	  いようにした.
+
+	* Fixnum:id2name - IDから文字列に戻す関数. String:internの逆.
+
+	* Array: 配列の範囲外の要素をアクセスした時に例外を発生させずに,
+	  nilを返すようにした. 配列は自動的に拡張される.
+
+	* string:stripを追加.
+
+	* -nオプションが-eオプションを複数指定した時も動作するように.
+
+	* parse.yで<sys/types.h>もインクルードするようにした.
+
+	* fname周りの細かいbugを修正.
+
+Wed May 26 11:45:10 1994  Yukihiro Matsumoto  (matz@dyna)
+
+	* 定数をキャッシュするようにした. 繰り返しが多い場合には有効のはず
+	  だが, 一度しかアクセスしない場合は遅くなるなあ.
+
+Wed May 25 00:42:24 1994  Yukihiro Matsumoto  (matz@dyna)
+
+	* 多重代入文(foo, bar = 1, 2)の採用.
+
+	* 条件式部に文字列あるいは正規表現リテラルをおくと`=~'演算子によっ
+	  て`$_'と比較される. 更に`...'の両辺では整数リテラルが`$.'と比較
+	  される.
+
+Mon May 23 23:27:03 1994  Yukihiro Matsumoto  (matz@dyna)
+
+	* &式 形式はなくなった. 代わりにkernel:apply(id, args..)を導入.
+
+	* def op () ..形式の導入. opは再定義可能な演算子.
+
+	* constantの代入時チェック. 既に初期化されている定数に代入した場合
+	  は例外が発生する.
+
+	* 多重代入文.
+
+Thu May 19 22:57:07 1994  Yukihiro Matsumoto  (matz@dyna)
+
+	* 複合文でもvoid valueのチェックを行うようにした.
+
+	* untilの動作の修正(do..until型だった).
+
+Wed May 18 01:06:25 1994  Yukihiro Matsumoto  (matz@dyna)
+
+	* 移植に関する若干の問題を修正.
+
+	* 別名の構文を「def a b」にした.
+
+	* until/unless: 演算子から制御文へ. 例外を捕捉する機能はそのまま.
+
+	* 選択可能な機能をconfig.hからdefines.hに移動.
+
+Fri May 13 23:20:21 1994  Yukihiro Matsumoto  (matz@dyna)
+
+	* -yオプションを新設. -dオプションからコンパイラのデバッグ部分を分
+	  離した.
+
+Tue Apr 25 20:17:33 1994  Yukihiro Matsumoto  (matz@dyna)
+
+	* マルチバイト文字列を識別子に使えるように. 個人的には使いたくは無
+	  いけどなあ.
+
+	* `-v'フラグの状態を$verboseでアクセスできるように.
+
+	* CVSの導入に伴い, バージョン管理の方法を変更.
+
+	* 真面目にChangeLogをつける事にした.
+
+Tue Mar  8 10:09:25 1994  Yukihiro Matsumoto  (matz at nws119)
+
+	* %変数名 によるクラス定数を導入.
+
+	* undef メソッド によるメソッド定義の取り消しを導入.
+
+	* rb_get_method_bodyではthe_envを変更せず, rb_call()で明示的に変更
+	  するように. これでresponds_toなどで環境が破壊されない.
+
+Mon Mar  7 17:46:15 1994  Yukihiro Matsumoto  (matz at nws119)
+
+	* 「&文字列」形式. 「式.文字列」型のメッセージセンドはなくなった.
+
+	* 自己代入形式(+=. -=, ...)
+
+	* obj.attr = expr形式の採用.
+
+Thu Feb 24 16:23:28 1994  Yukihiro Matsumoto  (matz at nws119)
+
+	* toint, tofloat, print_stringをそれぞれto_i, to_f, to_sに変更.
+
+	* String:clone - Copy on Writeの実現.
+
+Tue Feb 22 11:11:44 1994  Yukihiro Matsumoto  (matz at nws119)
+
+	* re.c: マッチした文字列の保存に失敗していた.
+
+	* trap: 可能ならば処理に時間のかかるシステムコール(read, wait,
+	  sigpause, select)をフックして割り込み処理の即答性を高める(DOSな
+	  どでは無理だなあ).
+
+	* trap: 割り込みをその場で処理するか(迅速だが危険), 安全なタイミン
+	  グで処理するかを選択できるように.
+
+Tue Feb 17 11:11:12 1994  Yukihiro Matsumoto  (matz at nws119)
+
+	* trap: 割り込みハンドラ.
+
+Wed Feb 16 12:29:12 1994  Yukihiro Matsumoto  (matz at nws119)
+
+	* String:crypt: 暗号化ルーチン
+
+	* "::"演算子の追加. a::b は {a, b}と同義. a::b::c は {a, {b, c}}と
+	  同義(右結合). 同義とはいうものの, "::"演算子を使った方が少しだけ
+	  メモリ効率が良い.
+
+	* Dir.rmdir(), File.unlink(), File.utime() -- 各システムコールへの
+	  インタフェース.
+
+	* kill -- kill(2) I/F
+
+	* select(): readのチェックではstdioにバッファリングされているかど
+	  うかをチェックするように.
+
+Tue Feb 15 15:08:31 1994  Yukihiro Matsumoto  (matz at nws119)
+
+	* file.c: statをキャッシュするように.
+
+	* File:utime()を追加.
+
+	* unliteralize(): フラグを破壊していた.
+
+	* Bug(): coreを吐くように.
+
+	* String:tr -- tr(1)互換. 引数パターンがちょっと違うけど….
+
+Mon Feb 14 18:24:13 1994  Yukihiro Matsumoto  (matz at nws119)
+
+	* unless, untilが例外も偽と見なすように.
+
+	* select() -- select(2) I/F
+
+	* Array:pack, String:unpack: perlのpack/unpackの同等品
+
+Tue Feb  8 17:11:10 1994  Yukihiro Matsumoto  (matz at nws119)
+
+	* setenv()のないシステムのためにputenv()を使ったコードも用意した.
+
+Mon Feb  7 09:52:44 1994  Yukihiro Matsumoto  (matz at nws119)
+
+	* 引数の一番最後に`*'を置けるようにした. これでrest引数のリストを
+	  操作する必要が少なくなる.
+
+Fri Feb  4 18:23:26 1994  Yukihiro Matsumoto  (matz at nws119)
+
+	* ruby-mode.elを書き直す. ずいぶんましになったと思う.
+
+	* 文字列リテラルのCopy on Writeを実現. これで文字列がリテラルであ
+	  るからといっていちいちcloneしなくても済む.
+
+Tue Feb  1 09:21:09 1994  Yukihiro Matsumoto  (matz at nws119)
+
+	* sub(), gsub()で, マッチした文字列を$&, $1..$9でアクセスできるよ
+	  うにした. 同時にマッチした部分文字列をコピーしておくように(元の
+	  文字列が変更されても状態を保存するため).
+
+Mon Jan 31 15:16:58 1994  Yukihiro Matsumoto  (matz at nws119)
+
+	* プライベートメソッドの仕様を変更. 今までは同じクラスのメソッドか
+	  らしかアクセスできなかったが, サブクラスのメソッドからもアクセス
+	  できるようにした(C++におけるprotected メンバ関数).
+
+	* メソッドサーチのアルゴリズムを改善し, 10%程度の高速化を行なった.
+
+	* 高速化. Cで記述されたメソッドを呼び出す時にはsetjmpを呼ばないよ
+	  うにした. これでCメソッドを多用する場合には3倍程度高速になった.
+
+Fri Jan 28 15:44:04 1994  Yukihiro Matsumoto  (matz at nws119)
+
+	* sh-modeを元にruby-mode.elを作る. 演算子で終る, 2行に渡る文には対
+	  応していないけど….
+
+Thu Jan 27 11:35:19 1994  Yukihiro Matsumoto  (matz at nws119)
+
+	* freenode(): NODE_NILの解放忘れ.
+
+	* 字句解析部のバグ修正(コメントの後の状態を戻し忘れ).
+
+	* protect .. endのバグ修正. GC_LINKのネストが不正だった.
+
+	* joinのバグ修正(使っているオブジェクトをfreeしていた).
+
+	* splitのバグ修正(アルゴリズムがおかしかった).
+
+	* fork()を追加.
+
+Wed Jan 26 17:09:56 1994  Yukihiro Matsumoto  (matz at nws119)
+
+	* ファイルテストメソッドの追加.
+
+	* rb_autoexec(): クラスを初めてアクセスした時の挙動を制御できるよ
+	  うにした. これでautoloadも実現できる. これにともないメソッド
+	  unknownはなくなった.
+
+Tue Jan 25 15:51:36 1994  Yukihiro Matsumoto  (matz at nws119)
+
+	* Dbmクラス, Mathモジュールを作成.
+
+	* -Iオプションでサーチパスに追加できるように.

+
+	* Float,Fixnum:"**"

+
+	* ruby.h: 一時env.hに移動してたQselfの定義を復活. ただし今回は関数

+
+	* ruby.h: TRUEでsyntax errorにならないよう#undefを追加.
+
+	* eval.c(rb_eval): thread化に挑戦したが, 失敗(速くならなかった).
+	  が, Scopingなどの無駄なコードの削除とメソッド呼び出しの引数セッ

+	  更した. to_sで文字列に変換した時にも`t'と表示される. 更に踏み込
+	  んで`t'を予約語にしてlispのようにしようかとも思ったが, そこまで
+	  は決心できなかった. 一文字のローカル変数はかなり使いそうな気がす
+	  るので….
+
+	* array.c,dict.c: equalを再定義しているクラスで, hashを正しく定義
+	  した.
+
+Wed Sep 28 23:30:28 1994  Yukihiro Matsumoto  (matz@dyna)
+
+	* eval.c(Ffail): 今までfailはカーネルクラスのメソッドであったが,
+	  構文に組み込んだ. この変更によって, 1)`fail'は予約語となり, ロー
+	  カル変数に用いることができなくなった. 2)`fail'単体で例外を発生す
+	  るようになった. 3)failはメソッドではなくなったので再定義される可
+	  能性がなくなった.
+
+	* dic.c, dbm.c(indexes): Arrayのindexesと同様の機能を持つメソッド
+	  を追加.
+
+	* array.c(indexes): 引数をインデックスとする要素の配列を返す. 整数

+
+	* parse.y(value_expr): 式がnilの時に対応.

+
+	* re.c:	正規表現内で「\数字」形式が指定できるように.
+
+	* parse.y:「do expr using var ... end」形式はなくなった. 寂しい気
+	  もする. *BACKWARD INCOMPATIBILITY*
+
+Mon Sep  5 10:59:01 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* numeric.c(next): Numericクラスにもnextを提供.
+
+	* string.c(upto): uptoを提供.
+
+	* range.c(each): nextを使ったインタフェースからuptoを使うように変

+
+Fri Sep  2 15:25:39 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* dict.c(each): 戻り値を[key, value]のペアに変更. 今までのeachは
+	  each_valueとして残る. *BACKWARD INCOMPATIBILITY*
+
+Thu Sep  1 10:49:04 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* 成功した(特別な戻り値を持たない)システムコールは`0'を返すように.
+
+Wed Aug 31 00:26:51 1994  Yukihiro Matsumoto  (matz@dyna)
+
+	* string.c: チェックサムを得るメソッド`sum'を作った.
+
+	* class.c(include_class_new): ICLASSのclassをもとのクラスにした.
+	  gcの際に元クラスをマークする必要があるのが, フィールドを増やす余
+	  地が無いので, classフィールドを流用した. 私の見積りが間違ってい
+	  て, ICLASSのインスタンスにメッセージを送る事があれば, おかしな動
+	  作をするだろう.
+
+	* eval.c(masign): 式(a,b = nil)の値を[nil]からnilに変更した.
+
+Mon Aug 29 11:56:09 1994  Yukihiro Matsumoto  (matz@ix-02)

+	  うになった.
+
+Fri Aug 26 10:46:30 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* spec: 整理された文法にしたがって書き直した.
+
+	* parse.y: ここ数日で混乱していた文法を整理した. 括弧を省略したメ

+	  になったこと, returnにリストが渡せるようになったことが主な変更点
+	  である.
+
+	* process周りが怪しいがとにかくSolaris 2.3で動くように.
+
+	* parse.y: 曖昧性がない場合にはメソッド呼び出しの引数の括弧を省略
+	  できるように. 省略できるメソッド呼び出しの条件は, 1)かならず1個
+	  以上の引数を必要とすること, 2)第1引数が`+', `-', `(', `[', `{',
+	  `/'など, 式の始まりに置かれた時と途中に現れた時とで解釈が違う記
+	  号で始まらないこと, である.
+

+
+Wed Aug 24 00:01:15 1994  Yukihiro Matsumoto  (matz@dyna)

+	  return a, b, cはreturn [a, b, c]と同じ意味になる.
+
+	* parse.y: yield以外の大域脱出制御式をexprからexpr0に移した. よっ
+	  てメソッドの引数に制御式を使えなくなる(これで困る人はいないはず).
+
+	* parse.y: `+'の定数展開の際に演算子の優先順位を忘れていた.
+
+	* eval.c: untilの戻り値はnilになった.
+
+	* parse.y: modifierとしてのif/unless/while/untilを追加.
+
+	* parse.y: 文法からendの後ろにつけるキーワードを削除. ほとんど使わ
+	  なかった上に, emacsではruby-modeがあれば対応のチェックが機械的に
+	  出来るため.
+

+

+Fri Aug 19 11:44:13 1994  Yukihiro Matsumoto  (matz@ix-02)
+
+	* main.c: rubyをほかのプログラムに組み込めるようにmain()を分割した.
+	  それにともない, プログラムの呼び出し構造を修正した.
+
+	* parse.y: 条件式の定義を変更. ifなどの条件式の中でだけ`&&'や`||'
+	  および`!'の引数が条件式になるように. この変更により条件式以外の
+	  場所での `&&', `||', `!'演算子の動作が直観に一致する.
+
+	* parse.y: 実引数の`*'の後に続く引数はexprに制限した. 今までは全て
+	  の文が有効

+	  fds which are used by RubyVM internal.  In this version of
+	  CRuby, return 1 if fd is communication pipe.
+	  If your application needs to close all file descriptors to
+	  present resource leak, skip internal fds using this C API.
+	  We also define a macro RB_RESERVED_FD_P(fd).  So you can write
+	    #ifndef RB_RESERVED_FD_P
+	    #define RB_RESERVED_FD_P(fd) 0
+	    #endif
+	  for Ruby 1.9.2 or previous version to write compatible extensions.

+
+	* lib/benchmark.rb: merge eregon/benchmark.
+	  https://github.com/eregon/ruby/tree/benchmark
+	  patched by Benoit Daloze. [ruby-core:37593] [Bug #4940]
+
+	* lib/benchmark (Benchmark#bmbm): bmbm should be consistent with bm
+	  for the return value.
+
+	* test/benchmark: remove preemptive test instead of skipping
+	  I removed the preemptive test I wrote for Feature #4197.
+	  I'll add it back when the implementation will be able to satisfy it.
+
+	* lib/benchmark (Benchmark#bmbm): remove useless explicit call,
+	  #format is an alias of #to_s test/benchmark: add a test for
+	  format of long time.
+
+	* lib/benchmark: fix label width: always add 1 to ensure there is a
+	  space delimiter even with times over 100s
+	  When I asked for Feature #4197, I wanted to make delimiting spaces
+	  consistent for #bm and #bmbm.
+	  But with times over 100s, the output contains no space between the
+	  label and the first time (user).
+	  Now both ensure there is always a space, even if that means 3 spaces
+	  with times under 10s (because it is formatted as %10.6f)
+
+	* test/benchmark: let labels be a constant
+	  lib/benchmark (Benchmark#realtime): avoid creating an unused Proc
+	  lib/benchmark (Benchmark#benchmark): use ensure clause to restore
+	  STDOUT.sync, as in #bmbm

+	  several environment (we found a crash on FreeBSD).
+	  And remove const value "buff_size", and define CCP_READ_BUFF_SIZE
+	  macro.

+
+	* ext/syck/rubyext.c (mktime_do): avoid buffer overrun, by
+	  silently ignoring lesser significant digits.  Required buffer
+	  length can be computable so you might at first think of
+	  allocating enough memory space on the fly using alloca().  That
+	  is a wrong idea because when using alloca there is always risk
+	  of integer overflow.  A function that accepts outer-process
+	  resources like this should not blindly trust its inputs.  In
+	  this particular case we just want to generate milliseconds
+	  resolution by strtod() so the string in question needs no more
+	  length than what we originally have.  Ignoring lesser
+	  significant digits should suffice I believe.

+
+Wed Sep 15 13:37:00 2010  URABE Shyouhei  <shyouhei@ruby-lang.org>
+
+	* test/net/imap/test_imap.rb: "localhost" not guaranteed to
+	  resolve to "127.0.0.1".  On my machine it is "::1" instead.
+	  The problem is, you have to connect to the imaps server via
+	  the canonical name written in a server certificate, and that
+	  of the server.cert is "localhost".  So you have to listen to
+	  the address of what "localhost" resolves to.  I think this
+	  situation cannot be resolved in a handy manner because the
+	  test "test_imaps_post_connection_check" is actually
+	  expecting to connect to a server via an address other than
+	  the CN.  On my machine several assertions won't pass because
+	  the test cannot connect to the server.

+	  :widget=>'%W', :keycode=>'%k', '%x'=>:x, '%X'=>:root_x, and so on;
+	  those are attributes of event object). It means that Ruby/Tk accepts
+	  not only "widget.bind(ev, '%W', '%k', ...){|w, k, ...| ... }", but
+	  also "widget.bind(ev, :widget, :keycode, ...){|w, k, ...| ... }".
+	  It is potentially incompatible, when user passes symbols to the
+	  arguments of the callback block (the block receives the symbols as
+	  strings). I think that is very rare case (probably, used by Ruby/Tk
+	  experts only). When causes such trouble, please give strings instead
+	  of such symbol parameters (e.g. call Symbol#to_s method).

+
+	* ext/tk/lib/tkextlib/tile.rb: [incompatible] remove TileWidgets'
+	  instate/state/identify method to avoid the conflict with standard
+	  widget options. Those methods are renamed to ttk_instate/ttk_state/
+	  ttk_identify (tile_instate/tile_state/tile_identify are available
+	  too). Although I don't recommend, if you really need old methods,
+	  please define "Tk::USE_OBSOLETE_TILE_STATE_METHOD = true" before
+	  "require 'tkextlib/tile'".
+
+	* ext/tk/lib/tkextlib/tile.rb: "Tk::Tile::__Import_Tile_Widgets__!"
+	  is obsolete. It outputs warning. To control default widget set,
+	  use "Tk.default_widget_set = :Ttk".
+
+	* ext/tk/lib/tk.rb: __IGNORE_UNKNOWN_CONFIGURE_OPTION__ method and
+	  __set_IGNORE_UNKNOWN_CONFIGURE_OPTION__!(mode) method are defined
+	  as module methods of TkConfigMethod. It may help users to wrap old
+	  Ruby/Tk scripts (use standard widgets) to force to use Ttk widgets.
+	  Ttk widgets don't have some options of standard widgets which are
+	  control the view of widgets. When set ignore-mode true, configure
+	  method tries to ignore such unknown options with no exception.
+	  Of course, it may raise other troubles on the GUI design.
+	  So, those are a little danger methods.
+
+	* ext/tk/lib/tk/itemconfig.rb: __IGNORE_UNKNOWN_CONFIGURE_OPTION__
+	  method and __set_IGNORE_UNKNOWN_CONFIGURE_OPTION__!(mode) method
+	  are defined as module methods of TkItemConfigMethod as the same
+	  purpose as TkConfigMethod's ones.
+
+	* ext/tk/sample/ttk_wrapper.rb: A new example. This is a tool for
+	  wrapping old Ruby/Tk scripts (which use standard widgets) to use
+	  Ttk (Tile) widgets as default.
+
+	* ext/tk/sample/tkextlib/tile/demo.rb: use ttk_instate/ttk_state
+	  method instead of instate/state method.
+
+	* ext/tk/lib/tk/root, ext/tk/lib/tk/namespace.rb,
+	  ext/tk/lib/tk/text.rb, ext/tk/lib/tkextlib/*: some 'instance_eval's
+	  are replaced to "instance_exec(self)".
+
+	* ext/tk/lib/tk/event.rb: bug fix on KEY_TBL and PROC_TBL (?x is not
+	  a character code on Ruby1.9).
+
+	* ext/tk/lib/tk/variable.rb: support new style of operation argument
+	  on Tcl/Tk's 'trace' command for variables.
+
+	* ext/tk/sample/demos-jp/widget, ext/tk/sample/demos-en/widget: bug fix
+
+	* ext/tk/sample/demos-jp/textpeer.rb,

+
+	* ext/tk/lib/tkextlib/tile.rb: add method to define Tcl/Tk command
+	  to make Tcl/Tk theme sources (based on different version of Tile
+	  extension) available.
+	  (Tk::Tile::__define_LoadImages_proc_for_compatibility__)
+
+	* ext/tk/lib/tk.rb, ext/tk/lib/tk/wm.rb: support dockable frames
+	  (Tcl/Tk8.5 feature). 'wm' command can treat many kinds of widgets
+	  as toplevel widgets.
+
+	* ext/tk/lib/tkextlib/tile/style.rb: ditto.
+	  (Tk::Tile::Style.__define_wrapper_proc_for_compatibility__)
+
+	* ext/tk/lib/tk/font.rb: add actual_hash and metrics_hash to get
+	  properties as a hash. metrics_hash method returns a boolean value
+	  for 'fixed' option. But metrics method returns numeric value
+	  (0 or 1) for 'fixed' option, because of backward compatibility.
+
+	* ext/tk/lib/tk/timer.rb: sometimes fail to set callback procedure.
+
+	* ext/tk/lib/tk.rb: add Tk.sleep and Tk.wakeup method. Tk.sleep
+	  doesn't block the eventloop. It will be better to use the method
+	  in event callbacks.
+
+	* ext/tk/sample/tksleep_sample.rb: sample script about Tk.sleep.

+
+	* ext/tk/lib/tk.rb, ext/tk/lib/*: make default widget set
+	  switchable between Tk (standard Tcl/Tk widget set) and
+	  Ttk (Tile). Initial default widget set is Tk. Now, toplevel
+	  widget classes are removed and defined as aliases.
+	  For example, "TkButton" is an alias of the "Tk::Button" class.
+	  Those aliases are replaced when switching default widget set.
+	  "Tk.default_widget_set=" is the method for switching default
+	  widget set. "Tk.default_widget_set = :Ttk" defines Ttk (Tile)
+	  widget set as default. It means that "TkButton" denotes
+	  "Tk::Tile::Button" class. And then, "TkButton.new" creates
+	  a Tk::Tile::Button widget. Of course, you can back to use
+	  standard Tk widgets as the default widget set by calling
+	  "Tk.default_widget_set = :Tk", whenever you want. Based on
+	  the feature, you can use Ttk widget styling engine on your
+	  old Ruby/Tk application without modifying its source, if you
+	  don't use widget options unsupported on Ttk widgets (At first,
+	  call "Tk.default_widget_set = :Ttk", and next load and run
+	  your application).
+	  This is one step for supporting Tcl/Tk8.5 features.

+	  SyckParser's hash table. if GC occurs in st_insert, it's not under
+	  SyckParser's mark system yet. so RString can be released wrongly.
+
+	* ext/syck/syck.h (S_FREE): small hack. no need to check if pointer is
+	  NULL or not before S_FREE.
+
+	* ext/syck/rubyext.c (syck_parser_assign_io): rb_check_string_type can
+	  return new RString. if so, it becomes unreachable from GC after
+	  returns syck_parser_assign_io, and can be freed by GC. (dangling
+	  in syck io system) so extends its life time till syck_parse is called.
+
+	* ext/syck/rubyext.c (syck_parser_s_alloc): always allocates bonus,
+	  so no need to check if NULL, and "volatile VALUE hash"
+	  is not needed. (bonus->port was not protected in syck_emitter_reset)
+
+	* ext/syck/rubyext.c (syck_mark_parser): ditto.

+
+	* ext/syck/rubyext.c: sorry, I reverted my "should set newly
+	  allocated memory instead of RString's internal storage" stuff.
+	  node allocated in rubyext.c seems to be freed by rb_syck_free_node
+	  not syck_free_node, and it won't free data.str->ptr and type_id.
+
+	 (I still think this is unsafe because RString(foo)->ptr becomes
+	  dangling pointer when RString is modified or freed, but anyway
+	  I misunderstood, so go back to original code for now)

+

+
+Thu Oct  9 12:05:46 2003  Eric Sunshine  <sunshine@sunshineco.com>
+
+	* configure.in: revived NextStep, OpenStep, and Rhapsody ports which
+	  had become unbuildable; enhanced --enable-fat-binary option so that
+	  it accepts a list of desired architectures (rather than assuming a
+	  fixed list), or defaults to a platform-appropriate list if user does
+	  not provide an explicit list; made the default list of architectures
+	  for MAB (fat binary) more comprehensive; now uses -fno-common even
+	  when building the interpreter (in addition to using it for
+	  extensions), thus allowing the interpreter to be embedded into a
+	  plugin module of an external project (in addition to allowing
+	  embedding directly into an application); added checks for
+	  <netinet/in_systm.h> (needed by `socket' extension) and getcwd(); now
+	  ensures that -I/usr/local/include is employed when extensions'
+	  extconf.rb scripts invoke have_header() since extension checks on
+	  NextStep and OpenStep will fail without it if the desired resource
+	  resides in the /usr/local tree; fixed formatting of --help message.
+
+	* Makefile.in: $(LIBRUBY_A) rule now deletes the archive before
+	  invoking $(AR) since `ar' on Apple/NeXT can not "update" MAB archives
+	  (see configure's --enable-fat-binary option); added rule for new
+	  missing/getcwd.c.
+
+	* defines.h: fixed endian handling during MAB build (see configure's
+	  --enable-fat-binary option) to ensure that all portions of the
+	  project see the correct WORDS_BIGENDIAN value (some extension modules
+	  were getting the wrong endian setting); added missing constants
+	  GETPGRP_VOID, WNOHANG, WUNTRACED, X_OK, and type pid_t for NextStep
+	  and OpenStep; removed unnecessary and problematic HAVE_SYS_WAIT_H
+	  define in NeXT section.
+
+	* dir.c: do not allow NAMLEN() macro to trust dirent::d_namlen on
+	  NextStep since, on some installations, this value always resolves
+	  uselessly to zero.
+
+	* dln.c: added error reporting to NextStep extension loader since the
+	  previous behavior of failing silently was not useful; now ensures
+	  that NSLINKMODULE_OPTION_BINDNOW compatibility constant is defined
+	  for OpenStep and Rhapsody; no longer includes <mach-o/dyld.h> twice
+	  on Rhapsody since this header lacks multiple-include protection,
+	  which resulted in "redefinition" compilation errors.
+
+	* main.c: also create hard reference to objc_msgSend() on NeXT
+	  platforms (in addition to Apple platforms).
+
+	* lib/mkmf.rb: now exports XCFLAGS from configure script to extension
+	  makefiles so that extensions can be built MAB (see configure's
+	  --enable-fat-binary option); also utilize XCFLAGS in cc_command()
+	  (but not cpp_command() because MAB flags are incompatible with
+	  direct invocation of `cpp').
+
+	* ext/curses/extconf.rb: now additionally checks for presence of these
+	  curses functions which are not present on NextStep or Openstep:
+	  bkgd(), bkgdset(), color(), curs(), getbkgd(), init(), scrl(), set(),
+	  setscrreg(), wattroff(), wattron(), wattrset(), wbkgd(), wbkgdset(),
+	  wscrl(), wsetscrreg()
+
+	* ext/curses/curses.c: added appropriate #ifdef's for additional set of
+	  curses functions now checked by extconf.rb; fixed curses_bkgd() and
+	  window_bkgd() to correctly return boolean result rather than numeric
+	  result; fixed window_getbkgd() to correctly signal an error by
+	  returning nil rather than -1.
+
+	* ext/etc/etc.c: setup_passwd() and setup_group() now check for null
+	  pointers before invoking rb_tainted_str_new2() upon fields extracted
+	  from `struct passwd' and `struct group' since null pointers in some
+	  fields are common on NextStep/OpenStep (especially so for the
+	  `pw_comment' field) and rb_tainted_str_new2() throws an exception
+	  when it receives a null pointer.
+
+	* ext/pty/pty.c: include "util.h" for strdup()/ruby_strdup() for
+	  platforms such as NextStep and OpenStep which lack strdup().
+
+	* ext/socket/getaddrinfo.c: cast first argument of getservbyname(),
+	  gethostbyaddr(), and gethostbyname() from (const char*) to non-const
+	  (char*) for older platforms such as NextStep and OpenStep.
+
+	* ext/socket/socket.c: include "util.h" for strdup()/ruby_strdup() for
+	  platforms such as NextStep and OpenStep which lack strdup(); include
+	  <netinet/in_systm.h> if present for NextStep and OpenStep; cast first
+	  argument of gethostbyaddr() and getservbyname() from (const char*) to
+	  non-const (char*) for older platforms.
+
+	* ext/syslog/syslog.c: include "util.h" for strdup()/ruby_strdup() for
+	  platforms such as NextStep and OpenStep which lack strdup().

+
+	* vm.c: support variable VM/Machine stack sizes.
+	  Specified by the following environment variables:
+	    - RUBY_THREAD_VM_STACK_SIZE: vm stack size used at thread creation.
+	      default: 128KB (32bit CPU) or 256KB (64bit CPU).
+	    - RUBY_THREAD_MACHINE_STACK_SIZE: machine stack size used at thread
+	      creation. default: 512KB or 1024KB.
+	    - RUBY_FIBER_VM_STACK_SIZE: vm stack size used at fiber creation.
+	      default: 64KB or 128KB.
+	    - RUBY_FIBER_MACHINE_STACK_SIZE: machine stack size used at fiber
+	      creation. default: 256KB or 256KB.
+	  This values are specified at launched timing. You can not change
+	  these values at running time.
+	  Environ variables are only *hints* because:
+	    - They are aligned to 4KB.
+	    - They have minimum values (depend on OSs).
+	    - Machine stack settings are ignored by some OSs.
+	  Default values especially fiber stack sizes are increased.
+	  This change affect Fiber's behavior:
+	    (1) You can run more complex program on a Fiber.
+	    (2) You can not make many (thousands) Fibers because of
+	        lack of address space (on 32bit CPU).
+	  If (2) bothers you,
+	    (a) Use 64bit CPU with big memory, or
+	    (b) Specify RUBY_FIBER_(VM|MACHINE)_STACK_SIZE correctly.
+	  You need to choose correct stack size carefully. These values
+	  are completely rely on systems (OS/compiler and so on).

+
+	* method.h: remove `VM_METHOD_TYPE_CFUNC_FRAMELESS' method type.
+	  This method type is for optimized CFUNC such as Fixnum#+ and so on.
+	  This feature is half-baked and no way to use them.
+	  [Background]
+	  Now, VM has opt_plus instructions to optimize `+' methods for
+	  some Classes (such as Fixnum, Float (flonum)). We call this
+	  type of instructions as `specialized instructions'.
+	  This simple technique improve simple program dramatically.
+	  However, we can make specialized instructions for only several
+	  types (classes) and selectors (method names) because a large
+	  instruction will be slow. In other words, this technique has no
+	  extensibility.
+	  To overcome this problem, VM_METHOD_TYPE_CFUNC_FRAMELESS was
+	  introduced (r37198). This type is a variant of CFUNC, but called
+	  their functions directly without building a method frame.
+	  Any CFUNC method can be defined as frameless methods if a method
+	  is not needed to make method frame. Frameless methods are faster
+	  as specialized instructions (a bit slower, but no need to care).
+	  No problem described at
+	  http://charlie.bz/blog/why-do-singleton-methods-make-ruby-slow
+	  because this technique doesn't see class, but see method body
+	  itself. Alias is also no problem.
+	  [Problem]
+	  However, we can't set frameless method type for polymorphic methods
+	  such as Array#[]. Necessity for method frame depends on which
+	  parameter type. For example, Fixnum#+ needs method frame if
+	  coerce is needed. Current VM_METHOD_TYPE_CFUNC_FRAMELESS is not
+	  flexible and need more tuning to introduce it.
+	  Expected behavior of frameless method type may be:
+	    result = optimized_cfunc(params); /* call optimized cfunc */
+	    if (result == Qundef) { result = normal_cfunc(); }
+	  This is why I say this feature is half-baked.
+	  We need to learn primitive method in Smalltalk more.
+	  (I heard this name at RubyConf Taiwan this month. Thanks!)
+	  [Conclusion]
+	  I remove this feature and consider again.
+	  This feature goes to next minor (2.1?).
+	  Nobody may use this feature and there is no compatibility issue.
+
+	* proc.c (rb_method_entry_arity): ditto.
+
+	* vm_eval.c, vm_insnhelper.c, vm_method.c: ditto.
+
+Tue Dec 18 04:58:22 2012  Koichi Sasada  <ko1@atdot.net>
+
+	* vm_trace.c (fill_id_and_klass): TracePoint#defined_class returns
+	  singleton class. `set_trace_func' passed attached class (which is
+	  attached/modified by singleton class) by 6th block parameter if it
+	  is singleton class. Previous behavior follows this spec.
+	  However, this method named `defined_class' should return singleton
+	  class directly because singleton methods are defined in singleton
+	  class. There are no compatible issue because TracePoint is introduced
+	  after 2.0.
+	  But compatibility with `set_trace_func' is broken. This means that
+	  you can not replace all `set_trace_func' code with TracePoint
+	  without consideration of this behavior.
+	  [Bug #7554]
+
+	* test/ruby/test_settracefunc.rb: change a test to catch up

+
+	* eval.c (rb_using_refinement): skip the above superclass (the
+	  refined class) when creating iclasses for refinements.  Otherwise,
+	  `using Refinement1; using Refinement2' creates iclasses:
+	  <Refinement2> -> <RefinedClass> -> <Refinement1> -> RefinedClass,

+	  searched before Refinement1.  The correct iclasses should be
+	  <Refinement2> -> <Refinement1> -> RefinedClass.
+
+	* vm_insnhelper.c (vm_search_normal_superclass): if klass is an
+	  iclass for a refinement, use the refinement's superclass instead
+	  of the iclass's superclass.  Otherwise, multiple refinements are
+	  searched by super.  For example, if a refinement Refinement2
+	  includes a module M (i.e., Refinement2 -> <M> -> RefinedClass,
+	  and if refinements iclasses are <Refinement2> -> <M>' ->
+	  <Refinement1> -> RefinedClass, then super in <Refinement2> should
+	  use Refinement2's superclass <M> instead of <Refinement2>'s
+	  superclass <M>'.
+
+	* vm_insnhelper.c (vm_search_super_method): do not raise a
+	  NotImplementError if current_defined_class is a module included
+	  into a refinement.  Because of the change of

+
+Thu Dec  6 18:23:05 2012  Shugo Maeda  <shugo@ruby-lang.org>
+
+	* revised r37993 to avoid SEGV/ILL in tests.  In r37993, a method
+	  entry with VM_METHOD_TYPE_REFINED holds only the original method
+	  definition, so ci->me is set to a method entry allocated in the
+	  stack, and it causes SEGV/ILL.  In this commit, a method entry
+	  with VM_METHOD_TYPE_REFINED holds the whole original method entry.
+	  Furthermore, rb_thread_mark() is changed to mark cfp->klass to
+	  avoid GC for iclasses created by copy_refinement_iclass().
+
+	* vm_method.c (rb_method_entry_make): add a method entry with
+	  VM_METHOD_TYPE_REFINED to the class refined by the refinement if
+	  the target module is a refinement.  When a method entry with
+	  VM_METHOD_TYPE_UNDEF is invoked by vm_call_method(), a method with
+	  the same name is searched in refinements.  If such a method is
+	  found, the method is invoked.  Otherwise, the original method in
+	  the refined class (rb_method_definition_t::body.orig_me) is
+	  invoked.  This change is made to simplify the normal method lookup
+	  and to improve the performance of normal method calls.
+
+	* vm_method.c (EXPR1, search_method, rb_method_entry),
+	  vm_eval.c (rb_call0, rb_search_method_entry): do not use
+	  refinements for method lookup.
+
+	* vm_insnhelper.c (vm_call_method): search methods in refinements if
+	  ci->me is VM_METHOD_TYPE_REFINED.  If the method is called by
+	  super (i.e., ci->call == vm_call_super_method), skip the same
+	  method entry as the current method to avoid infinite call of the
+	  same method.
+
+	* class.c (include_modules_at): add a refined method entry for each
+	  method defined in a module included in a refinement.
+
+	* class.c (rb_prepend_module): set an empty table to
+	  RCLASS_M_TBL(klass) to add refined method entries, because
+	  refinements should have priority over prepended modules.
+
+	* proc.c (mnew): use rb_method_entry_with_refinements() to get
+	  a refined method.
+
+	* vm.c (rb_thread_mark): mark cfp->klass for iclasses created by
+	  copy_refinement_iclass().
+
+	* vm.c (Init_VM), cont.c (fiber_init): initialize th->cfp->klass.
+
+	* test/ruby/test_refinement.rb (test_inline_method_cache): do not skip
+	  the test because it should pass successfully.
+
+	* test/ruby/test_refinement.rb (test_redefine_refined_method): new
+	  test for the case a refined method is redefined.

+
+	* vm_method.c (rb_method_entry_make): add a method entry with
+	  VM_METHOD_TYPE_REFINED to the class refined by the refinement if
+	  the target module is a refinement.  When a method entry with
+	  VM_METHOD_TYPE_UNDEF is invoked by vm_call_method(), a method with
+	  the same name is searched in refinements.  If such a method is
+	  found, the method is invoked.  Otherwise, the original method in
+	  the refined class (rb_method_definition_t::body.orig_def) is
+	  invoked.  This change is made to simplify the normal method lookup
+	  and to improve the performance of normal method calls.
+
+	* vm_method.c (EXPR1, search_method, rb_method_entry),
+	  vm_eval.c (rb_call0, rb_search_method_entry): do not use
+	  refinements for method lookup.

+	  super (i.e., ci->call == vm_call_super_method), skip the same
+	  method entry as the current method to avoid infinite call of the
+	  same method.
+
+	* class.c (include_modules_at): add a refined method entry for each
+	  method defined in a module included in a refinement.
+
+	* class.c (rb_prepend_module): set an empty table to
+	  RCLASS_M_TBL(klass) to add refined method entries, because
+	  refinements should have priority over prepended modules.
+
+	* proc.c (mnew): use rb_method_entry_with_refinements() to get
+	  a refined method.
+
+	* test/ruby/test_refinement.rb (test_inline_method_cache): do not skip
+	  the test because it should pass successfully.
+
+	* test/ruby/test_refinement.rb (test_redefine_refined_method): new

+	* lib/rubygems.rb (Gem.load_yaml): return if Kernel#gem is not defined

+
+	* vm_core.h, vm_insnhelper.c, vm_eval.c (OPT_CALL_CFUNC_WITHOUT_FRAME):
+	  add a new optimization and its macro `OPT_CALL_CFUNC_WITHOUT_FRAME'.
+	  This optimization makes all cfunc method calls `frameless', which
+	  is faster than ordinal cfunc method call.
+	  If `frame' is needed (for example, it calls another method with
+	  `rb_funcall()'), then build a frame. In other words, this
+	  optimization delays frame building.
+	  However, to delay the frame building, we need additional overheads:
+	    (1) Store the last call information.
+	    (2) Check the delayed frame building before the frame is needed.
+	    (3) Overhead to build a delayed frame.
+	  rb_thread_t::passed_ci is storage of delayed cfunc call information.
+	  (1) is lightweight because it is only 1 assignment to `passed_ci'.
+	  To achieve (2), we modify GET_THREAD() to check `passed_ci' every
+	  time. It causes 10% overhead on my environment.
+	  This optimization only works for cfunc methods which do not need
+	  their `frame'.
+	  After evaluation on my environment, this optimization does not
+	  effective every time. Because of this evaluation results, this
+	  optimization is disabled at default.
+
+	* vm_insnhelper.c, vm.c: add VM_PROFILE* macros to measure behaviour
+	  of VM internals. I will extend this feature.
+
+	* vm_method.c, method.h: change parameters of the `invoker' function.

+
+Wed Oct 17 08:32:46 2012  Koichi Sasada  <ko1@atdot.net>
+
+	* compile.c (compile_dstr_fragments): use `putobject' instead of
+	  `putstring' for all of strings used by NODE_DSTR because
+	  ruby users can not grab this string.
+	  For example, the string object of "baz" in "foo#{bar}baz"
+	  is located by `putobject' (users can not touch "baz" object
+	  directly). This change reduces GC pressure.
+	  This improvement is suggested by Aaron Patterson.

+Wed Oct 17 05:05:07 2012  Koichi Sasada  <ko1@atdot.net>
+
+	* vm_insnhelper.c (vm_invoke_block): vm_caller_setup_args() can skip

+
+Wed Oct 17 01:53:47 2012  Koichi Sasada  <ko1@atdot.net>
+
+	* vm_insnhelper.c (vm_getivar, vm_setivar): support index inline cache
+	  with rb_call_info_t to speedup `attr' getter and setter.
+	  Cached index is stored in rb_call_info_t::aux::index.
+	  `index' == 0 means not cached. `index' > 0 means cached and cached
+	  index is `index - 1'.
+
+	* insns.def ((get|set)instancevariable): use new wrapper functions
+	  vm_(get|set)instancevariable() defined in vm_insnhelper.c.
+
+	* vm_core.h (rb_call_info_t::aux): introduce new union data because
+	  opt_pc can share with index.

+	  if two or more executables are given.
+
+Tue Oct 16 21:59:01 2012  Koichi Sasada  <ko1@atdot.net>
+
+	* benchmark/driver.rb: some refactoring.
+	  (1) Remove `average differential'.
+	      In this benchmark driver, We should not care about `average'.
+	      We use fastest score because this score should not include
+	      any disturbances (affections of background process, etc).
+	      If you care about timing affect, I recommend `median'
+	      score with more than 5 examinations rather than simple
+	      `average' score (`average' score was affected by error scores).
+	  (2) Show log file name.

+
+Tue Oct 16 06:29:18 2012  Koichi Sasada  <ko1@atdot.net>
+
+	* vm_insnhelper.c (vm_call_method): disable CI_SET_FASTPATH() if
+	  this method call needs splat argument because cached functions
+	  (vm_call_attrset, vm_call_ivar, vm_call_cfunc_fast_(unary|binary))
+	  do not check an arity.
+
+	* bootstraptest/test_method.rb: add a test to check an above issue.
+
+Tue Oct 16 06:15:44 2012  Koichi Sasada  <ko1@atdot.net>
+
+	* method.h: introduce new method type VM_METHOD_TYPE_CFUNC_FAST.
+	  This method is similar to VM_METHOD_TYPE_CFUNC methods, but
+	  called cfunc without building new frame (does not push new control
+	  frame). If error is occurred in cfunc, the backtrace only shows
+	  caller frame and upper.
+	  This kind of methods can be added by rb_define_method_fast().
+	  This feature is similar to specialized instructions (opt_plus, etc),
+	  but more flexible (but a bit slower).
+
+	* class.c (rb_define_method_fast): added.
+	  Maybe it will be renamed soon.
+
+	* vm_insnhelper.c (vm_call_method): support method type
+	  VM_METHOD_TYPE_CFUNC_FAST.
+
+	* proc.c (rb_method_entry_arity): catch up new method type.
+
+	* vm_method.c (rb_add_method_cfunc_fast): added.
+
+Tue Oct 16 02:32:29 2012  Koichi Sasada  <ko1@atdot.net>
+
+	* vm_insnhelper.h (CI_SET_FASTPATH): add new parameter `enabled'.
+	  If `enable' is 0 then CI_SET_FASTPATH() doesn't work.
+	  And add new configuration option OPT_CALL_FASTPATH. If this macro
+	  was defined by 0, then CI_SET_FASTPATH() doesn't work any more.
+
+	* vm_insnhelper.c (vm_call_method): Pass `0' for `enabled' parameter
+	  of CI_SET_FASTPATH if this method is protected.
+
+Tue Oct 16 02:17:35 2012  Koichi Sasada  <ko1@atdot.net>
+
+	* vm_core.h (VM_CALL_*): rename VM_CALL_*_BIT
+	  to VM_CALL_* (remove `_BIT' suffix).
+	  Add comments on each macros.
+	  Remove unused macro VM_CALL_TAILRECURSION_BIT.

+	  rewrite file assertions.
+
+Mon Oct 15 09:41:17 2012  Koichi Sasada  <ko1@atdot.net>
+
+	* vm_insnhelper.c (VM_CALLEE_SETUP_ARG): skip CI_SET_FASTPATH() if
+	  it was called from vm_yield_setup_args().
+
+Mon Oct 15 05:20:13 2012  Koichi Sasada  <ko1@atdot.net>
+
+	* vm_insnhelper.h CI_SET_FASTPATH: introduce new macro
+	  `CI_SET_FASTPATH(ci, func)'. This macro set `ci->call' as `func'.
+	  `func' (ci->call) is called at the last of `send'
+	  (and `invokesuper') instruction.
+	  `CI_SET_FASTPATH' does not set `ci->call' when the method
+	  (stored in `ci->me') is `protected'.
+
+	* vm_insnhelper.c (vm_call_method): use `CI_SET_FASTPATH'.
+	  After several checking (visibility, argc checking), the result of
+	  checking can be reused until re-definition of this method
+	  with inline method cache.
+
+	  Note that this optimization is now experimental.
+	  If you find any problem about it, please tell us.
+
+Mon Oct 15 04:51:55 2012  Koichi Sasada  <ko1@atdot.net>
+
+	* vm_insnhelper.c: refactoring.
+	  - move all `call' related functions to the last of file.
+	  - make functions for respective method types in vm_call_method().
+	    (all functions have same function parameters)
+
+	* vm_core.h: add `opt_pc' field in `rb_call_info_t'
+	  as temporal variable.

+
+Mon Oct 15 03:51:46 2012  Koichi Sasada  <ko1@atdot.net>
+

+
+Mon Oct 15 02:51:16 2012  Koichi Sasada  <ko1@atdot.net>
+
+	* vm_eval.c (vm_call0_body): add new function.
+	  `vm_call0()' makes call_info struct and calls `vm_call0_body()'
+	  with this struct. In near future, `vm_call0()' will be removed
+	  because all of `vm_call0()' users setup call_info struct by itself.
+
+Mon Oct 15 01:38:06 2012  Koichi Sasada  <ko1@atdot.net>
+
+	* insns.def (send, invokesuper, invokeblock, opt_*), vm_core.h:
+	  use only a `ci' (rb_call_info_t) parameter instead of using
+	  parameters such as `op_id', 'op_argc', `blockiseq' and flag.
+	  These information are stored in rb_call_info_t at the compile
+	  time.
+	  This technique simplifies parameter passing at related
+	  function calls (~10% speedups for simple method invocation at
+	  my machine).
+	  `rb_call_info_t' also has new function pointer variable `call'.
+	  This `call' variable enables to customize method (block)
+	  invocation process for each place. However, it always call
+	  `vm_call_general()' at this changes.
+	  `rb_call_info_t' also has temporary variables for method
+	  (block) invocation.
+
+	* vm_core.h, compile.c, insns.def: introduce VM_CALL_ARGS_SKIP_SETUP
+	  VM_CALL macro.  This flag indicates that this call can skip
+	  caller_setup (block arg and splat arg).
+
+	* compile.c: catch up above changes.
+
+	* iseq.c: catch up above changes (especially for TS_CALLINFO).
+
+	* tool/instruction.rb: catch up above changes.
+
+	* vm_insnhelper.c, vm_insnhelper.h: ditto. Macros and functions
+	  parameters are changed.

+	* vm_trace.c, vm_core.h: simplify tracing mechanism.
+
+	  (1) add rb_hook_list_t data structure which includes
+	      hooks, events (flag) and `need_clean' flag.
+	      If the last flag is true, then clean the hooks list.
+	      In other words, deleted hooks are contained by `hooks'.
+	      Cleanup process should run before traversing the list.
+	  (2) Change check mechanism
+	      See EXEC_EVENT_HOOK() in vm_core.h.
+	  (3) Add `raw' hooks APIs
+	      Normal hooks are guarded from exception by rb_protect().
+	      However, this protection is overhead for too simple
+	      functions which never cause exceptions.  `raw' hooks
+	      are executed without protection and faster.
+	      Now, we only provide registration APIs.  All `raw'
+	      hooks are kicked under protection (same as normal hooks).
+
+	* include/ruby/ruby.h: remove internal data definition and
+	  macros.
+
+	* internal.h (ruby_suppress_tracing), vm_trace.c: rename
+	  ruby_suppress_tracing() to rb_suppress_tracing()

+	* vm.c (mark_event_hooks): move definition to vm_trace.c.

+	  with ruby_vm_event_flags.

+
+	* iseq.c, vm_eval.c: set th->base_block properly.
+	  th->base_block is information for (a) parsing, (b) compiling
+	  and (c) setting up the frame to execute the program passed by
+	  `eval' method.  For example, (1) parser need to know up-level
+	  variables to detect it is variable or method without paren.
+	  Befor (a), (b) and (c), VM set th->base_block by passed bindng
+	  (or previous frame information).  After execute (a), (b) and (c),
+	  VM should clear th->base_block.  However, if (a), (b) or (c)
+	  raises an exception, then th->base_block is not cleared.
+	  Problem is that the uncleared value th->balo_block is used for
+	  irrelevant iseq compilation.  It causes SEGV or critical error.
+	  I tried to solve this problem: to clear them before exception,
+	  but finally I found out that it is difficult to do it (Ruby
+	  program can be run in many places).
+	  Because of this background, I set th->base_block before
+	  compiling iseq and restore it after compiling.
+	  Basically, th->base_block is dirty hack (similar to global
+	  variable) and this patch is also dirty.

+
+	* vm_core.h: remove VM_FRAME_MAGIC_FINISH (finish frame type).
+	  Before this commit:
+	    `finish frame' was place holder which indicates that VM loop
+	    needs to return function.
+	    If a C method calls a Ruby methods (a method written by Ruby),
+	    then VM loop will be (re-)invoked.  When the Ruby method returns,
+	    then also VM loop should be escaped.  `finish frame' has only
+	    one instruction `finish', which returns VM loop function.
+	    VM loop function executes `finish' instruction, then VM loop
+	    function returns itself.
+	    With such mechanism, `leave' instruction (which returns one
+	    frame from current scope) doesn't need to check that this `leave'
+	    should also return from VM loop function.
+	    Strictly, one branch can be removed from `leave' instruction.
+	  Consideration:
+	    However, pushing the `finish frame' needs costs because
+	    it needs several memory accesses.  The number of pushing
+	    `finish frame' is greater than I had assumed.  Of course,
+	    pushing `finish frame' consumes additional control frame.
+	    Moreover, recent processors has good branch prediction,
+	    with which we can ignore such trivial checking.
+	  After this commit:
+	    Finally, I decide to remove `finish frame' and `finish'
+	    instruction.  Some parts of VM depend on `finish frame',
+	    so the new frame flag VM_FRAME_FLAG_FINISH is introduced.
+	    If this frame should escape from VM function loop, then
+	    the result of VM_FRAME_TYPE_FINISH_P(cfp) is true.
+	    `leave' instruction checks this flag every time.
+	    I measured performance on it.  However on my environments,
+	    it improves some benchmarks and slows some benchmarks down.
+	    Maybe it is because of C compiler optimization parameters.
+	    I'll re-visit here if this cause problems.
+
+	* insns.def (leave, finish): remove finish instruction.

+
+	* vm_core.h: remove lfp (local frame pointer) and rename
+	  dfp (dynamic frame pointer) to ep (environment pointer).
+	  This change make VM `normal' (similar to other interpreters).
+	  Before this commit:
+	    Each frame has two env pointers lfp and dfp.  lfp points
+	    local environment which is method/class/toplevel frame.
+	    lfp[0] is block pointer.
+	    dfp is block local frame. dfp[0] points previous (parent)
+	    environment pointer.
+	    lfp == dfp when frame is method/class/toplevel.
+	    You can get lfp from dfp by traversing previous environment
+	    pointers.
+	  After this commit:
+	    Each frame has only `ep' to point respective environment.
+	    If there is parent environment, then ep[0] points parent
+	    environment (as dfp).  If there are no more environment,
+	    then ep[0] points block pointer (as lfp).  We call such ep
+	    as `LEP' (local EP).  We add some macros to get LEP and to
+	    detect LEP or not.
+	    In short, we replace dfp and lfp with ep and LEP.
+	  rb_block_t and rb_binding_t member `lfp' and `dfp' are removed
+	  and member `ep' is added.
+	  rename rb_thread_t's member `local_lfp' and `local_svar' to
+	  `root_lep' and `root_svar'.
+	  (VM_EP_PREV_EP(ep)): get previous environment pointer.  This macro

+Sat May 26 13:40:29 2012  Koichi Sasada  <ko1@atdot.net>
+
+	* vm.c (RubyVM::FrameInfo): add a class to access each frame
+	  information.  You don't need to parse strings from caller().
+	  FrameInfo has the following methods:
+	    FrameInfo#name: method name, class name, etc with decorations.
+	    FrameInfo#basename: name without decorations.
+	    FrameInfo#line_no: line number.
+	    FrameInfo#filename: file name.
+	    FrameInfo#filepath: full filepath.
+	    FrameInfo#iseq: iseq if it is iseq frame (defined by ruby script)
+	    FrameInfo#to_s: return caller() method style string.
+	  RubyVM::FrameInfo.caller(n, lev) returns array of FrameInfo objects.
+	  The name "RubyVM::FrameInfo.caller" is long and ambiguous (it is
+	  confusing with Kernel::caller() method), we need to change the name
+	  before Ruby 2.0 release. Good names or comments are welcome.
+
+	* test/ruby/test_backtrace.rb: add a test for above change.

+
+	* vm.c (rb_backtrace_to_str_ary): fix to use backtrace_object().
+	  This change improve performance of caller(lev, n).
+
+	* benchmark/bm_vm3_backtrace.rb: added to check above improvement.
+	  FYI: measurement on my laptop, 1.9.3p229 needs 5.125 sec,

+
+	* ext/openssl/ossl_ssl.c: Allow disabling client-side renegotiation.
+	* test/openssl/test_ssl.rb: Simple tests for this.
+
+	  Client-side renegotiation is still considered problematic, even
+	  when used in the context of secure renegotiation (RI, RFC 5746).
+	  The changes allow users to either completely disable client
+	  renegotiation on the server, or to specify a maximum number of
+	  handshakes allowed in total. The number of total handshakes is
+	  counted in a callback set as SSL_set_info_callback. If the
+	  maximum number of handshakes is exceeded an error will be raised
+	  We do not support renegotiation in the OpenSSL extension, therefore
+	  this feature can only be tested externally.
+	  The feature is opt-in, the default setting will be to allow
+	  unlimited client renegotiation, as was the case before.
+
+Fri May 25 23:38:58 2012  Martin Bosslet  <Martin.Bosslet@googlemail.com>
+
+	* test/openssl/test_ssl.rb: Clarify the intention of errors to be
+	  expected. Two errors are possible when connection is refused due

+	  OpenSSL version in use.

+
+Fri May 25 19:51:36 2012  Koichi Sasada  <ko1@atdot.net>
+
+	* vm_eval.c (rb_f_caller): caller() method accepts second optional
+	  argument `n' which specify how many frames should return.
+	  For example, `caller(0, 1)' returns only one frame information
+	  which calls caller() method.  If there are less than n frame
+	  information, then all frame information are returned.  If n is 0,
+	  then always return [].
+	  This fix is part of [ruby-dev:42345] [Ruby 1.9-Feature#3917].
+	  However, performance and features are not enough.
+	  RDoc is also not available.
+
+	* test/ruby/test_backtrace.rb: add a test for above.

+
+Fri May 25 10:52:52 2012  Koichi Sasada  <ko1@atdot.net>
+
+	* vm.c: refactoring backtrace related functions.
+	  (1) unify similar functions (rb_backtrace_each() and
+	      backtrace_object()).  backtrace_each() is a unified function.
+	      variation:
+	      a) backtrace_object(): create backtrace object.
+	      b) vm_backtrace_str_ary(): create bt as an array of string.
+	      c) vm_backtrace_print(): print backtrace to specified file.
+	      d) rb_backtrace_print_as_bugreport(): print backtrace on
+	                                            bugreport style.
+	  (2) remove rb_backtrace_each().  Use backtrace_each() instead.
+	  (3) change the type of lev parameter to size_t.
+	      a) lev == 0 means current frame (exception, etc use it).
+	      b) lev == 1 means upper frame (caller(0) use it).
+
+	* vm_core.h, vm_dump.c, vm_eval.c: ditto.
+
+	* vm.c (backtrace_object(), vm_backtrace_str_ary()): fix to return a
+	  correct size of caller(lev) array.
+	  Let n be a "caller(0).size" then ln as caller(lev).size should be
+	  (n - lev).  However, the previous implementation returns a wrong
+	  size array (ln > n - lev).  [ruby-dev:45673]
+
+	* test/ruby/test_backtrace.rb: add tests for backtrace.

+	* error.c, eval_error.c: change for above.
+
+Thu May 24 14:30:13 2012  Koichi Sasada  <ko1@atdot.net>
+
+	* vm.c: add RubyVM::Backtrace object (btobj).
+	  Backtrace information contains an array consists of location
+	  information for each frames by string.
+	  RubyVM::Backtrace object is lightweight backtrace information,
+	  which contains complete information to generate traditional style
+	  backtrace (an array of strings) with faster generation.
+	  If someone accesses to backtrace information via
+	  Exception#backtrace, then convert a RubyVM::Backtrace object to
+	  traditional style backtrace.
+	  This change causes incompatibility on marshal dumped binary
+	  of Exception.  If you have any trouble on it, please tell us
+	  before Ruby 2.0 release.
+	  Note that RubyVM::Backtrace object should not expose Ruby level.
+
+	* error.c, eval.c, vm_eval.c: ditto.
+
+	* internal.h: ditto.
+
+	* eval_error.c: fix to skip "set_backtrace" method invocation in
+	  creating an exception object if it call a normal set_backtrace
+	  method (defined by core).
+
+	* test/ruby/test_settracefunc.rb: fix for above change.
+
+	* vm_method.c (rb_method_defined_by): added.  This function
+	  checks that the given object responds with the given method
+	  by the given cfunc.
+
+	* benchmark/bm_vm2_raise1.rb, benchmark/bm_vm2_raise2.rb:
+	  add to measure exception creation speed. raise1 create
+	  exception objects from shallow stack frame.  raise2 create
+	  exception objects from deep stack frame.

+
+	  In OpenSSL, OP_DONT_INSERT_EMPTY_FRAGMENTS is used to prevent
+	  TLS-CBC-IV vulnerability described at
+	  http://www.openssl.org/~bodo/tls-cbc.txt
+	  It's known issue of TLSv1/SSLv3 but it attracts lots of attention
+	  these days as BEAST attack. (CVE-2011-3389)
+
+	  Until now ossl sets OP_ALL at SSLContext allocation and call
+	  SSL_CTX_set_options at connection.  SSL_CTX_set_options updates the
+	  value by using |= so bits set by OP_ALL cannot be unset afterwards.
+
+	  This commit changes to call SSL_CTX_set_options only 1 time for each
+	  SSLContext. It sets the specified value if SSLContext#options= are
+	  called and sets OP_ALL if not.
+
+	  To help users to unset bits in OP_ALL, this commit also adds several
+	  constant to SSL such as
+	  OpenSSL::SSL::OP_DONT_INSERT_EMPTY_FRAGMENTS.  These constants were
+	  not exposed in Ruby because there's no way to unset bits in OP_ALL
+	  before.
+
+	  Following is an example to enable 0/n split for BEAST prevention.
+
+	    ctx.options = OP_ALL & ~OP_DONT_INSERT_EMPTY_FRAGMENTS
+
+	* test/openssl/test_ssl.rb: Test above option exists.

+
+Fri Aug 26 19:12:08 2011  Hiroshi Nakamura  <nahi@ruby-lang.org>
+
+	* variable.c: Make autoload thread-safe. See #921.
+
+	  What's the problem?
+	    autoload is thread unsafe. When we define a constant to be
+	    autoloaded, we expect the constant construction is invariant. But
+	    current autoload implementation allows other threads to access the
+	    constant while the first thread is loading a file.
+
+	  What's happening inside?
+	    The current implementation uses Qundef as a marker of autoload in
+	    Constant table. Once the first thread find Qundef as a value at
+	    constant lookup, it starts loading a defined feature. Generally a
+	    loaded file overrides the Qundef in Constant table by module/class
+	    declaration at very beginning lines of the file, so other threads
+	    can see the new Module/Class object before feature loading is
+	    finished. It breaks invariant construction.
+
+	  How to solve?
+	    To ensure invariant constant construction, we need to override
+	    Qundef with defined Object after the feature loading. For keeping
+	    Qundef in Constant table, I expanded autoload_data struct in
+	    Module to have a slot for keeping the defined object while feature
+	    loading. And changed Module's constant lookup/update logic a
+	    little so that the slot is only visible from the thread which
+	    invokes feature loading. (== the first thread which accessed the
+	    autoload constant)
+
+	  Evaluation?
+	    All test passes (bootstrap test, test-all and RubySpec) and added
+	    8 tests for threading behavior. Extra logics are executed only
+	    when Qundef is found, so no perf drop should happen except
+	    autoloading.
+
+	* variable.c (rb_autoload): Prepare new autoload_data struct.
+
+	* variable.c (rb_autoload_load): Load feature and update Constant

+	* variable.c (rb_const_defined_0): Ditto.
+
+	* variable.c (rb_const_set): When the specified constant is under
+	  autoloading, it sets the object only for the thread which starts
+	  autoloading. Otherwise, simply overrides Qundef with constant
+	  override warning.

+	  This problem is caused by changing dfp (dynamic env pointer)

+	  the dfp can be moved because VM copies env from VM stack to
+	  the heap.  At this copying, dfp was also changed.  To solve this

+
+	* internal.h: do not use ruby_sized_xrealloc() and ruby_sized_xfree()

+
+	  We don't need these function if malloc_usable_size() is available.

+
+	* gc.c: change terminology OLDSPACE -> OLDMALLOC.
+	  (oldspace -> oldmalloc for variable names)
+
+	  OLDSPACE is confusing because it is not includes slots.
+	  To more clearly, rename such as (oldspace_limit -> oldmalloc_limit).

+
+	* gc.c: change RGENGC_CHECK_MODE (>= 2) logic.
+	  Basically, make an object graph of all of living objects before and
+	  after marking and check status.
+
+	  [Before marking: check WB sanity]
+	  If there is a non-old object `obj' pointed from old object
+	  (`parent') then `parent' or `obj' should be remembered.
+
+	  [After marking: check marking miss]
+	  Traversible objects with the object graph should be marked.
+	  (However, this alert about objects pointed by machine context
+	   can be false positive. We only display alert.)
+
+	  [Implementation memo]
+	  objspace_allrefs() creates an object graph.
+	  The object graph is represented by st_table, key is object (VALUE)
+	  and value is referring objects. Referring objects are stored by
+	  "struct reflist".
+
+	* gc.c (init_mark_stack): do not use push_mark_stack_chunk() at init.
+	  This pre-allocation causes failure on is_mark_stack_empty()
+	  without any pushing.

+
+	* gc.c: add support to estimate increase of oldspace memory usage.
+	  This is another approach to solve an issue discussed at r43530.
+	  This feature is disabled as default.
+
+	  This feature measures an increment of memory consumption by oldgen
+	  objects. It measures memory consumption for each objects when
+	  the object is promoted. However, measurement of memory consumption
+	  is not accurate now. So that this measurement is `estimation'.
+
+	  To implement this feature, move memsize_of() function from
+	  ext/objspace/objspace.c and expose rb_obj_memsize_of().
+
+	  Some memsize() functions for T_DATA (T_TYPEDDATA) have problem to
+	  measure memory size, so that we ignores T_DATA objects now.
+	  For example, some functions skip NULL check for pointer.
+
+	  The macro RGENGC_ESTIMATE_OLDSPACE enables/disables this feature,
+	  and turned off as default.
+
+	  We need to compare 3gen GC and this feature carefully.
+	  (it is possible to enable both feature)
+	  We need a help to compare them.
+
+	* internal.h: expose rb_obj_memsize_of().
+
+	* ext/objspace/objspace.c: use rb_obj_memsize_of() function.

+
+	* gc.c: add 3gen GC patch, but disabled as default.
+
+	  RGenGC is designed as 2 generational GC, young and old generation.
+	  Young objects will be promoted to old objects after one GC.
+	  Old objects are not collect until major (full) GC.
+
+	  The issue of this approach is some objects can promote as old
+	  objects accidentally and not freed until major GC.
+	  Major GC is not frequently so short-lived but accidentally becoming
+	  old objects are not freed.
+
+	  For example, the program "loop{Array.new(1_000_000)}" consumes huge
+	  memories because short lived objects (an array which has 1M
+	  elements) are promoted while GC and they are not freed before major
+	  GC.
+
+	  To solve this problem, generational GC with more generations
+	  technique is known. This patch implements three generations gen GC.
+
+	  At first, newly created objects are "Infant" objects.
+	  After surviving one GC, "Infant" objects are promoted to "Young"
+	  objects.
+	  "Young" objects are promoted to "Old" objects after surviving
+	  next GC.
+	  "Infant" and "Young" objects are collected if it is not marked
+	  while minor GC. So that this technique solves this problem.
+
+	  Representation of generations:
+	  * Infant: !FL_PROMOTED and !oldgen_bitmap [00]
+	  * Young :  FL_PROMOTED and !oldgen_bitmap [10]
+	  * Old   :  FL_PROMOTED and  oldgen_bitmap [11]
+
+	  The macro "RGENGC_THREEGEN" enables/disables this feature, and
+	  turned off as default because there are several problems.
+	  (1) Failed sometimes (Heisenbugs).
+	  (2) Performance down.
+	      Especially on write barriers. We need to detect Young or Old
+	      object by oldgen_bitmap. It is slower than checking flags.
+
+	  To evaluate this feature on more applications, I commit this patch.
+	  Reports are very welcome.
+
+	  This patch includes some refactoring (renaming names, etc).
+
+	* include/ruby/ruby.h: catch up 3gen GC.

+	  Tomb heap is where zombie objects and ghost (freed slot) lived in.
+	  Separate from other heaps (now there is only eden heap) at sweeping
+	  helps freeing pages more efficiently.
+	  Before this patch, even if there is an empty page at former phase
+	  of sweeping, we can't free it.
+
+	  Algorithm:
+	    (1) Sweeping all pages in a heap and move empty pages from the
+	        heap to tomb_heap.
+	    (2) Check all existing pages and free a page
+	        if all slots of this page are empty and
+	           there is enough empty slots (checking by swept_num)
+
+	  To introduce this patch, there are several tuning of GC parameters.

+
+	  * Add ruby-electric-mode-hook.
+
+	  * Use a remap in binding ruby-electric-delete-backward-char.
+
+	  * Totally revamp electric keywords and then introduce electric
+	    return.  Modifier keywords are now properly detected making
+	    use of ruby-mode's indentation level calculator, and

+	  * block-mid keywords (then, else, elsif, when, rescue and

+
+	  * Add standardized comments for ELPA integration.
+
+	  * Fix interaction with smartparens-mode by disabling its end
+	    keyword completion, since ruby-electric has become more clever
+	    at it.
+
+	  * The custom variable `ruby-electric-keywords` is changed to
+	    `ruby-electric-keywords-alist`, allowing user to fine-grained

+
+	* gc.c: simplify threshold of GC caused by malloc_increase.
+	  Now, malloc_limit is increased/decreased by mysterious logic.
+	  This fix simplify malloc_limit increase/decrease logic such as:
+	    if (malloc_increase > malloc_limit) /* so many malloc */
+	      malloc_limit += malloc_limit * (GC_MALLOC_LIMIT_FACTOR-1);
+	    else
+	      malloc_limit -= malloc_limit * (GC_MALLOC_LIMIT_FACTOR-1)/4;
+	  Default value of GC_MALLOC_LIMIT_FACTOR is 1.8.
+	  malloc_limit is bounded by GC_MALLOC_LIMIT_MAX (256MB by default).
+	  This logic runs at gc_before_sweep(). So there are no effect from
+	  caused by lazy sweep. And we can remove malloc_increase2.
+
+	* gc.c (HEAP_MIN_SLOTS, FREE_MIN, HEAP_GROWTH_FACTOR): rename to
+	  GC_HEAP_MIN_SLOTS, GC_FREE_MIN, GC_HEAP_GROWTH_FACTOR respectively.
+	  Check them by `#ifndef' so you can specify these values outside gc.c.
+
+	* gc.c (ruby_gc_params_t): add initial_malloc_limit_factor and
+	  initial_malloc_limit_max.
+
+	* gc.c (vm_malloc_prepare, vm_xrealloc): use vm_malloc_increase to
+	  add and check malloc_increase.

+
+	* variable.c (rb_const_set): fix WB miss.
+
+	  WBs had located before creating reference between a klass
+	  and constant value. It causes GC bug.
+
+	    # pseudo code:
+	    WB(klass, value); # WB and remember klass
+	    st_insert(klass->const_table, const_id, value);
+
+	  `st_insert()' can cause GC before inserting `value' and
+	  forget `klass' from the remember set. After that, relationship
+	  between `klass' and `value' are created with constant table.
+	  Now, `value' can be young (shady) object and `klass' can be old
+	  object, without remembering `klass' object.
+	  At the next GC, old `klass' object will be skipped and
+	  young (shady) `value' will be miss-collected. -> GC bug
+
+	  Lesson: The place of a WB is important.

+
+	* ext/objspace/object_tracing.c: add two new methods:
+	  * ObjectSpace.allocation_class_path(o)
+	  * ObjectSpace.allocation_method_id(o)
+	  They are not useful for Object.new because they are always
+	  "Class" and :new.

+
+Mon May 27 18:57:28 2013  Koichi Sasada  <ko1@atdot.net>
+
+	* ext/objspace/objspace.c: support ObjectSpace.trace_object_allocations.
+	  Read the following test to know HOWTO.
+	  This feature is a sample of RUBY_INTERNAL_EVENT.
+
+	* test/objspace/test_objspace.rb: add a test.

+
+	* vm_trace.c (rb_postponed_job_flush, rb_postponed_job_register): use

+
+Mon May 27 09:24:03 2013  Koichi Sasada  <ko1@atdot.net>
+
+	* test/-ext-/postponed_job/test_postponed_job.rb: fix typo and class name.
+
+Mon May 27 09:05:17 2013  Koichi Sasada  <ko1@atdot.net>
+
+	* include/ruby/ruby.h, gc.c, vm_trace.c: add internal events.
+	  * RUBY_INTERNAL_EVENT_NEWOBJ: object created.
+	  * RUBY_INTERNAL_EVENT_FREE: object freed.
+	  * RUBY_INTERNAL_EVENT_GC_START: GC started.
+	  And rename `RUBY_EVENT_SWITCH' to `RUBY_INTERNAL_EVENT_SWITCH'.
+
+	  Internal events can not invoke any Ruby program because the tracing
+	  timing may be critical (under huge restriction).
+	  These events can be hooked only by C-extensions.
+	  We recommend to use rb_postponed_job_register() API to call Ruby
+	  program safely.
+
+	  This change is mostly written by Aman Gupta (tmm1).

+
+Mon May 27 06:22:41 2013  Koichi Sasada  <ko1@atdot.net>
+
+	* include/ruby/debug.h, vm_trace.c: add rb_postponed_job API.
+	  Postponed jobs are registered with this API. Registered jobs
+	  are invoked at `ruby-running-safe-point' as soon as possible.
+	  This timing is completely same as finalizer timing.
+
+	  There are two APIs:
+	  * rb_postponed_job_register(flags, func, data): register a
+	    postponed job with data. flags are reserved.
+	  * rb_postponed_job_register_one(flags, func, data): same as
+	    `rb_postponed_job_register', but only one `func' job is
+	    registered (skip if `func' is already registered).

+	  This change is mostly written by Aman Gupta (tmm1).
+	  https://bugs.ruby-lang.org/issues/8107#note-15

+
+	* gc.c (gc_stat): collect shade_operation_count,

+
+Mon May 27 01:15:22 2013  Koichi Sasada  <ko1@atdot.net>
+
+	* hash.c (rb_hash_tbl_raw), internal.h: added.

+
+	* proc.c (rb_method_entry_min_max_arity): fix missing break in switch.
+	  This was introduced in r38236, which is not intentional apparently.
+	  This has caused no actual harm because VM_METHOD_TYPE_OPTIMIZED is
+	  not used except for OPTIMIZED_METHOD_TYPE_SEND, but may do in

+	  This function reveal internal (hidden) object by rb_obj_hide().
+	  Note that do not change class before and after hiding.
+	  Only permitted example is:
+	    klass = RBASIC_CLASS(obj);
+	    rb_obj_hide(obj);
+	    ....
+	    rb_obj_reveal(obj, klass);
+
+	  TODO: API design. rb_obj_reveal() should be replaced with others.
+
+	  TODO: modify constified variables using cast may be harmful for
+	        compiler's analysis and optimization.
+	        Any idea to prohibit inserting RBasic::klass directly?
+	        If rename RBasic::klass and force to use RBASIC_CLASS(obj),
+	        then all codes such as `RBASIC(obj)->klass' will be
+	        compilation error. Is it acceptable? (We have similar
+	        experience at Ruby 1.9,
+	        for example "RARRAY(ary)->ptr" to "RARRAY_PTR(ary)".
+
+	* internal.h: add some macros.

+	    object.

+
+	  Before this patch, gc_marks_step() marks (white -> grey) fixed
+	  number objects. However, this strategy does not fit practical
+	  cases, for example too slow to make progress.
+
+	  This patch changes this strategy how many objects the
+	  gc_marks_step() should handle.
+
+	  We can estimate how many times gc_marks_step() is called during
+	  this major marking (== C) with the free slot number in pooled
+	  pages. We also can estimate the living object number (== L)
+	  using last marked_slots value. We can solve this problem (how
+	  many objects should be process in gc_marks_step()) by L/C.
+
+	* gc.c (rb_objspace_t): add rb_objspace_t::rincgc::pooled_slots and
+	  step_slots.

+	  [Feature #10440] (Details are described in this ticket)
+
+	  Most of complex part is moved to vm_args.c.
+
+	  Now, ISeq#to_a does not catch up new instruction format.

+	* insns.def (opt_send_simple): removed and add new instruction
+	  "opt_send_without_block".

+	* parse.y (new_args_tail_gen): reorder variables.
+	  Before this patch, a method "def foo(k1: 1, kr1:, k2: 2, **krest, &b)"
+	  has parameter variables "k1, kr1, k2, &b, internal_id, krest",
+	  but this patch reorders to "kr1, k1, k2, internal_id, krest, &b".
+	  (locate a block variable at last)

+	    (ruby process)
+	    (... repeat (5), (6))
+	  (7) GC_ENTER
+	      (finish lazy sweep)
+	    - (8) GC_END_SWEEP
+	  (9) GC_EXIT
+
+	  2nd example (incremental major marking):
+	  (1) GC_ENTER
+	  - (2) GC_START (minor GC)
+	    (start incremental marking)
+	  (3) GC_EXIT
+	    (ruby process)
+	  (4) GC_ENTER
+	    (incremental marking)
+	  (5) GC_EXIT
+	     (ruby process)
+	     (... repeat (4), (5))
+	  (6) GC_ENTER
+	    (finish incremental marking)
+	  - (7) GC_END_MARK
+	    (start lazy sweep)
+	  (8) GC_EXIT
+	    (ruby process)
+	  (9) GC_ENTER
+	    (lazy sweep)
+	  (10) GC_EXIT
+	    (ruby process)
+	    (... repeat (9), (10))
+	  (11) GC_ENTER
+	    (finish lazy marking)
+	  - (12) GC_STOP_SWEEP
+	  (13) GC_EXIT

+	  This change also introduces the following changes.
+
+	  * Remove RGENGC_AGE2_PROMOTION and introduce object age (0 to 3).
+	    Age can be count with FL_PROMOTE0 and FL_PROMOTE1 flags in
+	    RBasic::flags (2 bit). Age == 3 objects become old objects.
+	  * WB_PROTECTED flag in RBasic to WB_UNPROTECTED bitmap.
+	  * LONG_LIVED bitmap to represent living objects while minor GCs
+	    It specifies (1) Old objects and (2) remembered shady objects.
+	  * Introduce rb_objspace_t::marked_objects which counts marked
+	    objects in current marking phase. marking count is needed to
+	    introduce incremental marking.
+	  * rename mark related function and sweep related function to
+	    gc_(marks|sweep)_(start|finish|step|rest|continue).
+	  * rename rgengc_report() to gc_report().

+	  never a serious bug.  But is annoying indeed to see warnings
+	  every time.  I added `=0` and all went healthy.
+
+	* configure.in: Also, I found that the problematic macro expansion
+	  only happens when we lack __typeof__ C extension, which shall
+	  not be the case of my compiler.  I added AC_C_TYPEOF to kick ass.

+	             write `buff' with WB(ary, &buff[i], obj)
+	             -> if `ary' and `shared' are old, then only `ary'
+	                will be remembered.
+	             -> traverse from `ary'. But `shared' is old, so
+	                that written `obj' is not marked.
+
+	  It cause WB miss so that shared arrays were WB-unprotected.
+	  (WB-unprotected objects are marked everytime if it is living)

+
+	  For example, this method is useful to test iseq dumper/loader

+
+	  Because this method is for such internal experimental usage,
+	  the interface is not matured. For example, this interface has

+
+	* vm_insnhelper.c: introduce new call handler for simple ISeqs.
+
+	  vm_call_iseq_setup_normal_0start() is simple, however it has
+	  some loops/conditions depends on ISeq::param.size and
+	  ISeq::local_size (in vm_push_frame(), inlined into this function).
+
+	  There are many simple methods which has a few parameters and local
+	  variables. So that this patch introduces several special functions
+	  generated in vm_call_iseq_optimized.inc by
+	  tool/mk_call_iseq_optimized.rb.
+
+	  This script makes
+	    vm_call_iseq_setup_normal_0start_Xparams_Ylocals()
+	  where X is 0 to 3 and Y is 1 to 6 (as current setting).
+	  In this case, X * Y = 24 functions are created.
+
+	  These functions creates fast method dispatch by inlining
+	  vm_push_frame() with immediate params/locals sizes.
+
+	  On my laptop, we can have the following results.
+
+	  vm2_method*       1.083 (8.3% faster)
+	  vm2_poly_method*  0.961 (3.4% slower)
+
+	  It shows 8.3% faster for inner loop method dispatch (hit inline
+	  cache), but 3.4% slower when inline cache miss because we need
+	  to find a suitable call handler.
+
+	* common.mk: add a rule for vm_call_iseq_optimized.inc.
+
+	* tool/mk_call_iseq_optimized.rb: added.
+

+
+	  Trying to deq from a closed empty queue return nil
+	  if exception parameter equals to false (default).
+
+	  If exception parameter is truthy, it raises
+	  ClosedQueueError (< StopIteration).
+	  ClosedQueueError inherits StopIteration so that you can write:
+
+	    loop{ e = q.deq; (using e) }
+
+	  Trying to close a closed queue raises ClosedQueueError.
+
+	  Blocking threads to wait deq for Queue and SizedQueue will be
+	  restarted immediately by returning nil (exception=false) or
+	  raising a ClosedQueueError (exception=true).
+
+	  Blocking threads to wait enq for SizedQueue will be

+
+	* ext/thread/thread.c: move definitions of Queue, SizedQueue
+	  and ConditionalVariables to thread_tools.c. In other words,
+	  such classes are built-in.
+	  [Feature #8919]
+
+	  At first, I planned to embed only a Queue class.
+	  However, rubygems requires 'thread.rb' (rubygems are
+	  required at first, when launch MRI without --disable-gems).
+	  So most of people require 'thread.rb' as an embedded library.
+
+	  Now, ext/thread/thread.c is empty, only for a dummy for
+	  compatibility.
+
+	* thread.c: move a definition of Mutex class to thread_tools.c.
+
+	  And define Mutex class under Thread (so now Mutex is Thread::Mutex).
+	  Because other thread related classes are also defined under Thread.
+	  We remain ::Mutex as Thread::Mutex. Only an inspect result is changed.
+
+	* common.mk: add dependency from thread.o to thread_tools.c.
+
+Sat Aug 22 05:31:37 2015  Koichi Sasada  <ko1@atdot.net>
+
+	* vm_opts.h, iseq.c, iseq.h: add compile option to force frozen
+	  string literals.
+	  [Feature #11473]
+
+	  This addition is not specification change, but to try frozen
+	  string literal world discussed on [Feature #11473].
+
+	  You can try frozen string literal world using this magical line:
+
+	    RubyVM::InstructionSequence.compile_option =
+	      {frozen_string_literal: true}
+
+	  Note that this is a global compilation option, so that you need to
+	  compile another script like that:
+
+	    p 'foo'.frozen? #=> false
+	    RubyVM::InstructionSequence.compile_option =
+	      {frozen_string_literal: true}
+	    p 'foo'.frozen? #=> false, because this line is already compiled.
+	    p eval("'foo'.frozen?") #=> true
+
+	  Details:
+	    * String literals are deduped by rb_fstring().
+	    * Dynamic string literals ("...#{xyz}...") is now only frozen,
+	      not deduped. Maybe you have other ideas.
+
+	  Now, please do not use this option on your productions :)
+	  Of course, current specification can be changed.
+
+	* compile.c: ditto.
+
+	* test/ruby/test_iseq.rb: add a test.

+
+	* method.h: introduce rb_callable_method_entry_t to remove
+	  rb_control_frame_t::klass.
+	  [Bug #11278], [Bug #11279]
+
+	  rb_method_entry_t data belong to modules/classes.
+	  rb_method_entry_t::owner points defined module or class.
+
+	    module M
+	      def foo; end
+	    end
+
+	  In this case, owner is M.
+
+	  rb_callable_method_entry_t data belong to only classes.
+	  For modules, MRI creates corresponding T_ICLASS internally.
+	  rb_callable_method_entry_t can also belong to T_ICLASS.
+
+	  rb_callable_method_entry_t::defined_class points T_CLASS or
+	  T_ICLASS.
+	  rb_method_entry_t data for classes (not for modules) are also
+	  rb_callable_method_entry_t data because it is completely same data.
+	  In this case, rb_method_entry_t::owner == rb_method_entry_t::defined_class.
+
+	  For example, there are classes C and D, and includes M,
+
+	    class C; include M; end
+	    class D; include M; end
+
+	  then, two T_ICLASS objects for C's super class and D's super class
+	  will be created.
+
+	  When C.new.foo is called, then M#foo is searched and
+	  rb_callable_method_t data is used by VM to invoke M#foo.
+
+	  rb_method_entry_t data is only one for M#foo.
+	  However, rb_callable_method_entry_t data are two (and can be more).
+	  It is proportional to the number of including (and prepending)
+	  classes (the number of T_ICLASS which point to the module).
+
+	  Now, created rb_callable_method_entry_t are collected when
+	  the original module M was modified. We can think it is a cache.
+
+	  We need to select what kind of method entry data is needed.
+	  To operate definition, then you need to use rb_method_entry_t.
+
+	  You can access them by the following functions.
+
+	  * rb_method_entry(VALUE klass, ID id);
+	  * rb_method_entry_with_refinements(VALUE klass, ID id);
+	  * rb_method_entry_without_refinements(VALUE klass, ID id);
+	  * rb_resolve_refined_method(VALUE refinements, const rb_method_entry_t *me);
+
+	  To invoke methods, then you need to use rb_callable_method_entry_t
+	  which you can get by the following APIs corresponding to the
+	  above listed functions.
+
+	  * rb_callable_method_entry(VALUE klass, ID id);
+	  * rb_callable_method_entry_with_refinements(VALUE klass, ID id);
+	  * rb_callable_method_entry_without_refinements(VALUE klass, ID id);
+	  * rb_resolve_refined_method_callable(VALUE refinements, const rb_callable_method_entry_t *me);
+
+	  VM pushes rb_callable_method_entry_t, so that rb_vm_frame_method_entry()
+	  returns rb_callable_method_entry_t.
+	  You can check a super class of current method by
+	  rb_callable_method_entry_t::defined_class.
+
+	* method.h: renamed from rb_method_entry_t::klass to
+	  rb_method_entry_t::owner.
+
+	* internal.h: add rb_classext_struct::callable_m_tbl to cache
+	  rb_callable_method_entry_t data.
+
+	  We need to consider about this field again because it is only
+	  active for T_ICLASS.

+	* class.c (method_entry_i): ditto.

+
+	* process.c (exec_with_sh, proc_exec_cmd): On Solaris 10,
+	  because ALWAYS_NEED_ENVP is 1 and envp_str is always generated,

+	  To guarantee this, execv() is replaced by a macro to print

+
+	* process.c (proc_exec_sh): Because proc_exec_sh() may be called
+	  by rb_proc_exec() with envp_str = Qfalse, execl() is replaced
+	  by a macro that calls execle() with "extern char **environ"
+	  traditional global variable on Solaris 10.
+	  TODO: This may be unsafe and should be changed in the future.
+	  Although rb_proc_exec() is not used from inside current version
+	  of ruby, it may be called by third-party extensions.

+	  * NOEX_VCALL       -> MISSING_VCALL (enum missing_reason)
+	  * NOEX_RESPONDS    -> BOUND_RESPONDS (macro)
+
+	  Now, NOEX_NOREDEF is not supported (I'm not sure it is needed).
+
+	  Background:
+	    I did not know what "NOEX" stands for.
+	    I asked Matz (who made this name) and his answer was "Nothing".
+	    "At first, it meant NO EXport (private), but the original
+	    meaning was gone."
+	    This is why I remove the mysterious word "NOEX" from MRI.

+	  children of [Old obj] at the beginning of marking.
+
+	  Added (but disabled) code changes current behaviour. This fix promote
+	  [New obj] to old and marks as a remembered old object. We can assume
+	  "new objects referred from old objects are maybe long-lived old
+	  objects".
+
+	  Disadvantage of added algorithm is we may promote unwilling
+	  short-lived objects. For example, consider many new objects push and
+	  pop to an old stack object. All of new objects (short-lived objects)
+	  promote to old objects unexpectedly.
+
+	  To compare these behaviour, I add this new code (but disabled it).

+
+	* internal.h: remove struct method_table_wrapper.
+	  struct method_table_wrapper was introduced to avoid duplicate marking
+	  for method tables.
+
+	  For example, `module M1; def foo; end; end` make one method table
+	  (mtbl) contains a method `foo`. M1 (T_MODULE) points mtbl.
+	  Classes C1 and C2 includes M1, then two T_ICLASS objects are created
+	  and they points mtbl too. In this case, three objects (one T_MODULE
+	  and two T_ICLASS objects) points same mtbl. On marking phase, these
+	  three objects mark same mtbl. To avoid such duplication, struct
+	  method_table_wrapper was introduced.
+
+	  However, created two T_ICLASS objects have same or shorter lifetime
+	  than M1 (T_MODULE) object. So that we only need to mark mtbl from M1,
+	  not from T_ICLASS objects. This patch tries marking only from M1.
+	  In other words, original module (M1) has responsibility to mark mtbl.
+	  Because of no duplicate marking, we don't need method_table_wrapper
+	  any more.
+
+	  Note that one `Module#prepend` call creates two T_ICLASS objects.
+	  One for referring to a prepending Module object, same as
+	  `Module#include`. We don't need to care this T_ICLASS.
+	  One for moving original mtbl from a prepending class. We need to
+	  mark such mtbl from this T_ICLASS object. To mark the mtbl,
+	  we need to use `RCLASS_ORIGIN(klass)` on marking from a prepended
+	  class `klass`.

+	  2) Prohibit GC while invoking T_DATA/T_FILE data structure

+
+	  This patch can introduce another memory consuming issue because
+	  Ruby-level finalizers can run after (2), GC is disabled.
+	  However, basically object consistency was broken at (2) as I
+	  described above. So that running Ruby-level finalizers contains
+	  danger originally. Because of this point, I need to suggest to
+	  remove these 3 lines (invoking remaining finalizers). And add a
+	  rule to add that finalizers should not add new finalizers, or
+	  say there is no guarantee to invoke finalizers that added by
+	  another finalizer.

+
+	* configure.in (WARN_UNUSED_RESULT): moved to here.
+
+	* configure.in (RUBY_FUNC_ATTRIBUTE): change function declaration
+	  to return int rather than void, because it makes no sense for a
+	  warn_unused_result attributed function to return void.
+
+	  Funny thing however is that it also makes no sense for noreturn
+	  attributed function to return int.  So there is a fundamental
+	  conflict between them.  While I tested this, I confirmed both
+	  GCC 6 and Clang 3.8 prefers int over void to correctly detect
+	  necessary attributes under this setup.  Maybe subject to change
+	  in future.
+
+	* internal.h (UNINITIALIZED_VAR): renamed to MAYBE_UNUSED, then

+
+	* string.c (rb_str_modify_expand): Check that the new length is in the

+	  Therefore simply rshift and cast as signed long works fine.

+	  is not defined when ext/openssl is built with OpenSSL 1.1.0.

+Sun Jun 19 21:25:43 2016  Kazuki Yamaguchi  <k@rhe.jp>
+
+	* ext/openssl/ossl_ocsp.c: Add OCSP::SingleResponse that represents an
+	  OCSP SingleResponse structure. Also add two new methods #responses
+	  and #find_response to OCSP::BasicResponse. A BasicResponse has one or
+	  more SingleResponse. We have OCSP::BasicResponse#status that returns
+	  them as an array of arrays, each containing the content of a
+	  SingleResponse, but this is not useful. When validating an OCSP
+	  response, we need to look into the each SingleResponse and check their
+	  validity but it is not simple. For example, when validating for a
+	  certificate 'cert', the code would be like:
+
+	    # certid_target is an OpenSSL::OCSP::CertificateId for cert
+	    basic = res.basic
+	    result = basic.status.any? do |ary|
+	      ary[0].cmp(certid_target) &&
+	        ary[4] <= Time.now && (!ary[5] || Time.now <= ary[5])
+	    end
+
+	  Adding OCSP::SingleResponse at the same time allows exposing
+	  OCSP_check_validity(). With this, the code above can be rewritten as:
+
+	    basic = res.basic
+	    single = basic.find_response(certid_target)
+	    result = single.check_validity

+	  objects. Currently they accepts only relative seconds from the current
+	  time. This is inconvenience, especially for revocationTime. When
+	  Integer is passed, they are still treated as relative times. Since the
+	  type check is currently done with rb_Integer(), this is a slightly
+	  incompatible change. Hope no one passes a relative time as String or
+	  Time object...
+	  Also, allow passing nil as nextUpdate. It is optional.

+
+	* ext/openssl/ossl_ssl.c (ossl_sslctx_s_alloc): Enable the automatic
+	  curve selection for ECDH by calling SSL_CTX_set_ecdh_auto(). With
+	  this a TLS server automatically selects a curve which both the client
+	  and the server support to use in ECDH. This changes the default
+	  behavior but users can still disable ECDH by excluding 'ECDH' cipher
+	  suites from the cipher list (with SSLContext#ciphers=). This commit
+	  also deprecate #tmp_ecdh_callback=. It was added in Ruby 2.3.0. It
+	  wraps SSL_CTX_set_tmp_ecdh_callback() which will be removed in OpenSSL
+	  1.1.0. Its callback receives two values 'is_export' and 'keylength'
+	  but both are completely useless for determining a curve to use in

+
+	  (ossl_sslctx_set_ecdh_curves): Add SSLContext#ecdh_curves=. Wrap

+
+	* ext/openssl/lib/openssl/ssl.rb (SSLSocket): Move the implementation of
+	  SSLSocket#initialize to C. Initialize the SSL (OpenSSL object) in it.
+	  Currently this is delayed until ossl_ssl_setup(), which is called from
+	  SSLSocket#accept or #connect. Say we call SSLSocket#hostname= with an
+	  illegal value. We expect an exception to be raised in #hostname= but
+	  actually we get it in the later SSLSocket#connect. Because the SSL is
+	  not ready at #hostname=, the actual call of SSL_set_tlsext_host_name()
+	  is also delayed.
+	  This also fixes: [ruby-dev:49376] [Bug #11724]
+
+	* ext/openssl/ossl_ssl.c (ossl_ssl_initialize): Added. Almost the same

+
+	  (ossl_ssl_setup): Adjust to the changes. Just set the underlying IO to
+	  the SSL.

+	  (ssl_started): Added. Make use of SSL_get_fd(). This returns -1 if not

+	  (ossl_ssl_data_get_struct): Removed. Now GetSSL() checks that the SSL
+	  exists.

+	  (ossl_ssl_set_session): Don't call ossl_ssl_setup() here as now the
+	  SSL is already instantiated in #initialize.

+
+	  (Init_ossl_ssl): Add method declarations of SSLSocket#{initialize,

+Mon Apr  4 17:43:45 2016  Koichi Sasada  <ko1@atdot.net>
+
+	* gc.c: change default value of
+	  RUBY_GC_HEAP_FREE_SLOTS_MIN_RATIO 0.3 -> 0.2
+	  RUBY_GC_HEAP_FREE_SLOTS_MAX_RATIO 0.8 -> 0.65
+
+	  These values are same as Ruby 2.0.0.
+
+	  This change cause GC counts.
+	  However, generational GC reduced each (minor) GC time and
+	  increase memory locality. So that not so big impact on my
+	  benchmarking results.
+	  (surprisingly, this fix speed up programs on some cases)
+
+	  You can change these values by environment variables
+	  if you feel wrong.
+
+Mon Apr  4 17:36:52 2016  Koichi Sasada  <ko1@atdot.net>
+
+	* gc.c (get_envparam_double): take an upper_bound.
+
+	  And also take an accept_zero flag which allow to accept zero
+	  even if lower_bound is set.
+
+	* gc.c (ruby_gc_set_params): fix parameters.
+
+	  RUBY_GC_HEAP_FREE_SLOTS_MAX_RATIO set 0.9 as *lower_bound*, so that
+	  it should be upper_bound.
+	  Set RUBY_GC_HEAP_FREE_SLOTS_MIN_RATIO as lower bound.
+
+	  Also set lower/upper bound of RUBY_GC_HEAP_FREE_SLOTS_GOAL_RATIO to
+	  RUBY_GC_HEAP_FREE_SLOTS_MIN/MAX_RATIO.

+
+Fri Apr  1 20:58:33 2016  Martin Duerst  <duerst@it.aoyama.ac.jp>
+
+	* enc/unicode/case-folding.rb, casefold.h: Data generation to implement
+	  swapcase functionality for titlecase characters. Swapcase isn't defined
+	  by Unicode, because the purpose/usage of swapcase is unclear anyway.
+	  The implementation follows a proposal from Nobu, swapping the case of
+	  each component of a titlecase character individually.
+	  This means that the titlecase characters have to be decomposed.
+
+	* enc/unicode.c: Code using the above data.
+
+	* test/ruby/enc/test_case_mapping.rb: Tests for the above.
+
+Fri Apr  1 14:55:28 2016  Kazuki Yamaguchi  <k@rhe.jp>
+
+	* configure.in (AC_CONFIG_FILES): $srcdir/.git can be a file pointing
+	  the real git_dir, such as when the git working tree is a "linked
+	  working tree" (a working tree created by git-worktree). So use
+	  git-rev-parse --git-dir to check if $srcdir is the top-level of a git
+	  repository, not just checking if the $srcdir/.git directory does exist
+	  or not.  [ruby-core:74759] [Bug #12239]
+
+	* tool/change_maker.rb: use tool/vcs.rb to detect VCS. This used to have
+	  its own VCS detection code, while we have tool/vcs.rb.
+
+	* tool/vcs.rb (detect): remove code duplication

+
+Thu Mar 31 19:16:16 2016  Koichi Sasada  <ko1@atdot.net>
+
+	* gc.c: need to set initial value of GC_HEAP_FREE_SLOTS_GOAL_RATIO.
+
+Thu Mar 31 17:50:27 2016  Koichi Sasada  <ko1@atdot.net>
+
+	* gc.c: change additional allocation policy.
+
+	  Introduce new environment variable
+	  RUBY_GC_HEAP_FREE_SLOTS_GOAL_RATIO (goal_ratio) to calculate the
+	  ratio of additional memory.
+
+	  Before this change, we add pages with the following formula
+	  (when free_slots < total_pages * RUBY_GC_HEAP_FREE_SLOTS_MIN_RATIO):
+	    next_pages = total_pages * RUBY_GC_HEAP_GROWTH_FACTOR
+
+	  This addition can allocate too much.
+
+	  With this change, we increase pages to satisfy the following formula:
+	    next_free_slots = next_total_slots * goal_ratio
+	  where
+	    next_free_slots = free_slots + adding_slots
+	    next_total_slots = total_slots + adding_slots.
+
+	  If you want to prepare many free slots, increase this ratio.
+
+	  If this variable is 0, then simply multiply
+	  RUBY_GC_HEAP_GROWTH_FACTOR.
+
+	* gc.c (get_envparam_double): enable to accept 0.
+
+Thu Mar 31 17:48:25 2016  Koichi Sasada  <ko1@atdot.net>
+
+	* gc.c (gc_marks_finish): fix syntax error.
+
+Thu Mar 31 16:49:36 2016  Koichi Sasada  <ko1@atdot.net>
+
+	* gc.c: simplify allocate/free detecting logic at the end of marking.
+
+	  Before this change, heap_pages_min_slots are calculated at the
+	  beginning sweeping phase. And this value is used at the end of
+	  *next* marking phase.
+
+	  To simplify it, we use this value at the end of this marking phase.
+	  It means that we don't need to store this value as global state.
+
+	  Also heap_pages_max_slots is calculated at the begging of sweeping
+	  phase and used at the end of sweeping phase.
+	  To simplify this logic, we introduced new global value
+	  heap_pages_freeable_pages it means extra pages count we can free.
+	  gc_sweep_step() checks this value and moves empty pages to tomb_heap
+	  not more than this value.
+
+	  Because of this fix, heap_pages_swept_slots is no longer needed.
+
+	* gc.c (rb_objspace_t::heap_pages): restruct the objspace global
+	  status.
+
+	  remove the following fields
+	    * swept_slots (and heap_pages_swept_slots)
+	    * min_free_slots (and heap_pages_min_free_slots)
+	    * max_free_slots (and heap_pages_max_free_slots)
+	  And add the following filed.
+	    * freeable_pages (and heap_pages_freeable_pages)
+
+	* gc.c (heap_pages_free_unused_pages): unlink tomb heap pages
+	  because tomb heap should have only freeable pages.
+
+	* gc.c (heap_extend_pages): add parameters for future extension.
+
+Thu Mar 31 16:43:02 2016  Koichi Sasada  <ko1@atdot.net>
+
+	* gc.c: add GC parameters to configure the following values:
+	  * RUBY_GC_HEAP_FREE_SLOTS_MIN_RATIO:
+	    allocate additional pages when free slots is lower than
+	    the value (total_slots * (this ratio)).
+	  * RUBY_GC_HEAP_FREE_SLOTS_MAX_RATIO:
+	    allow to free pages when free slots is greater than
+	    the value (total_slots * (this ratio)).
+
+	  Before this change, these values are hard coded.
+
+	* gc.c (ruby_gc_params_t): ditto.
+
+	* gc.c (ruby_gc_set_params): ditto.
+
+Thu Mar 31 15:59:17 2016  Koichi Sasada  <ko1@atdot.net>

+
+	* gc.c (gc_verify_heap_pages): check also tomb heap.
+

+
+	* gc.c (gc_page_sweep): return free slots count.
+
+	* gc.c (gc_sweep_step): use returned free slots count.
+
+	* gc.c (gc_sweep_step): change variable name `next'
+	  to `next_sweep_page'.

+
+	  r53381 changed to accept only Symbol or String for accessors, but
+	  there are several rubygems that pass classes (e.g. Array,
+	  Hash, ...) as accessors. Prior r53381, it was accepted because Class#to_s
+	  returns its class name. After r53381 given accessors are checked
+	  with define_method, but it accepts only Symbol or String, otherwise
+	  raises TypeError.
+
+	      def_delegator Foo, :some_method
+
+	  This change is to revert unexpected incompatibility. But this behavior
+	  may change in the future.

+= NEWS for Ruby 1.8.7
+
+This document is a list of user visible feature changes made between
+releases except for bug fixes.
+
+Note that each entry is kept so brief that no reason behind or
+reference information is supplied with.  For a full list of changes
+with all sufficient information, see the ChangeLog file.
+
+== Changes since the 1.8.6 release
+
+=== Configuration changes
+
+* default C flags
+
+  Some C compiler flags may be added by default depending on your
+  environment.  Specify optflags=.. and warnflags=.. as necessary to
+  override them.
+
+* vendor_ruby directory
+
+  A new library directory named `vendor_ruby' is introduced in
+  addition to `site_ruby'.  The idea is to separate libraries
+  installed by the package system (`vendor') from manually (`site')
+  installed libraries preventing the former from getting overwritten
+  by the latter, while preserving the user option to override vendor
+  libraries with site libraries. (`site_ruby' takes precedence over
+  `vendor_ruby')
+
+  If you are a package maintainer, make each library package configure
+  the library passing the `--vendor' option to `extconf.rb' so that
+  the library files will get installed under `vendor_ruby'.
+
+  You can change the directory locations using configure options such
+  as `--with-sitedir=DIR' and `--with-vendordir=DIR'.

+
+=== Interpreter Implementation
+
+* passing a block to a Proc [experimental]
+
+  This implementation in current shape is known to be buggy/broken,
+  especially with nested block invocation.  Take this as an
+  experimental feature.
+
+* stack trace
+
+  On non-SystemStackError exception, full stack trace is shown.
+
+=== Compatibility issues (excluding feature bug fixes)
+
+* String#slice! had some unintentional bugs and they have been fixed
+  because either they disagreed with documentation or their respective
+  behavior of #slice.  Unfortunately, this causes some
+  incompatibilities in the following (somewhat rare) cases.
+
+  * #slice! no longer expands the array when an out-of-boundary value
+    is given.
+
+      # Ruby 1.8.6
+      a = [1,2]
+      a.slice!(4,0)   #=> nil
+      a               #=> [1,2,nil,nil]
+
+      # Ruby 1.8.7
+      a = [1,2]
+      a.slice!(4,0)   #=> nil
+      a               #=> [1,2]
+
+  * #slice! no longer raises an exception but returns nil when a
+    negative length or out-of-boundary negative position is given.
+
+      # Ruby 1.8.6
+      a = [1,2]
+      a.slice!(1,-1)  #=> (raises IndexError)
+      a.slice!(-5,1)  #=> (raises IndexError)
+
+      # Ruby 1.8.7
+      a = [1,2]
+      a.slice!(1,-1)  #=> nil
+      a.slice!(-5,1)  #=> nil
+
+* String#to_i, String#hex and String#oct no longer accept a sequence
+  of underscores (`__') as part of a number.
+
+    # Ruby 1.8.6
+    '1__0'.to_i     #=> 10
+    '1__0'.to_i(2)  #=> 2  # 0b10
+    '1__0'.oct      #=> 8  # 010
+    '1__0'.hex      #=> 16 # 0x10
+
+    # Ruby 1.8.7
+    '1__0'.to_i     #=> 1
+    '1__0'.to_i(2)  #=> 1
+    '1__0'.oct      #=> 1
+    '1__0'.hex      #=> 1
+
+  The old behavior was inconsistent with Ruby syntax and considered as
+  a bug.
+
+* date
+
+  * Date.parse
+
+    '##.##.##' (where each '#' is a digit) is now taken as 'YY.MM.DD'
+    instead of 'MM.DD.YY'.  While the change may confuse you, you can
+    always use Date.strptime() when you know what you are dealing
+    with.
+
+* REXML
+
+  * REXML::Document.entity_expansion_limit=
+
+    New method to set the entity expansion limit. By default the limit is
+    set to 10000.  See the following URL for details.
+
+    https://www.ruby-lang.org/en/news/2008/08/23/dos-vulnerability-in-rexml/
+
+* stringio
+
+  * StringIO#each_byte
+
+    The return value changed from nil to self.  This is what the
+    document says and the same as each_line() does.
+
+* tempfile
+
+  * The file name format has changed.  No dots are included by default
+    in temporary file names any more.  See above for how to specify a
+    suffix.
+
+* uri
+
+  * See above for details.
+
+== Changes since the 1.8.5 release
+
+=== New platforms/build tools support
+
+* IA64 HP-UX
+
+* Visual C++ 8 SP1
+
+* autoconf 2.6x
+
+=== Global constants
+
+* RUBY_PATCHLEVEL
+
+  New constant since 1.8.5-p1.
+
+=== Library updates (outstanding ones only)
+
+* builtin classes
+
+  * New method: Kernel#instance_variable_defined?
+
+  * New method: Module#class_variable_defined?
+
+  * New feature: Dir::glob() can now take an array of glob patterns.
+
+* date
+
+  * Updated based on date2 4.0.3.
+
+* digest
+
+  * New internal APIs for C and Ruby.
+
+  * Support for autoloading.
+
+      require 'digest'
+
+      # autoloads digest/md5
+      md = Digest::MD5.digest("string")
+
+  * New digest class methods: file
+
+  * New digest instance methods: clone, reset, new, inspect,
+    digest_length (alias size or length), block_length()
+
+  * New library: digest/bubblebabble
+
+  * New function: Digest(name)
+
+* fileutils
+
+  * New option for FileUtils.cp_r(): :remove_destination
+
+* nkf
+
+  * Updated based on nkf as of 2007-01-28.
+
+* thread
+
+  * Replaced with much faster mutex implementation in C.  The former
+    implementation, which is slow but considered to be stable, is
+    available with a configure option `--disable-fastthread'.
+
+* tk
+
+  * Updated Tile extension support based on Tile 0.7.8.
+
+  * Support --without-X11 configure option for non-X11 versions of
+    Tcl/Tk (e.g. Tcl/Tk Aqua).
+
+  * New sample script: irbtkw.rbw -- IRB on Ruby/Tk. It has no trouble
+    about STDIN blocking on Windows.
+
+* webrick
+
+  * New method: WEBrick::Cookie.parse_set_cookies()
+
+=== Compatibility issues (excluding feature bug fixes)
+
+* builtin classes
+
+  * String#intern now raises SecurityError when $SAFE level is greater
+    than zero.
+
+* date
+
+  * Time#to_date and Time#to_datetime are added as private methods.
+    They cause name conflict error in ActiveSupport 1.4.1 and prior,
+    which comes with Rails 1.2.2 and prior.  Updating ActiveSupport
+    and/or Rails to the latest versions fixes the problem.
+
+* digest
+
+  * The constructor does no longer take an initial string to feed.
+    The following examples show how to migrate:
+
+      # Before
+      md = Digest::MD5.new("string")
+      # After (works with any version)
+      md = Digest::MD5.new.update("string")
+
+      # Before
+      hd = Digest::MD5.new("string").hexdigest
+      # After (works with any version)
+      hd = Digest::MD5.hexdigest("string")
+
+  * Digest::Base#==
+
+    * self == string
+
+      Automatic detection between binary digest values and hexadecimal
+      digest values has been dropped.  It is always assumed that a
+      hexadecimal digest value is given for comparison.
+
+    * self == md
+
+      Digest objects are compared by the resulting digest values, not
+      by the exact vector states.
+
+* fileutils
+
+  * A minor implementation change breaks Rake <=0.7.1.
+    Updating Rake to 0.7.2 or higher fixes the problem.
+
+* tk
+
+  * Tk::X_Scrollable (Y_Scrollable) is renamed to Tk::XScrollable
+    (YScrollable). Tk::X_Scrollable (Y_Scrollable) is still available,
+    but it is an alias name.

+= NEWS for Ruby 1.9.1
+
+This document is a list of user visible feature changes made between
+releases except for bug fixes.
+
+Note that each entry is kept so brief that no reason behind or
+reference information is supplied with.  For a full list of changes
+with all sufficient information, see the ChangeLog file.
+
+== Changes since the 1.8.7 release
+See doc/NEWS-1.8.7 for changes between 1.8.6 and 1.8.7.
+
+=== Compatibility issues
+
+* language core
+
+    * New syntax and semantics
+          o Block arguments are always local
+          o New semantics for block arguments
+          o defined? and local variables
+          o Parser expects that your source code has only valid byte
+            sequence in some character encoding.  Use magic comments
+            to tell the parser which encoding you use.
+          o New semantics for constant definition in instance_eval
+            or in module_eval.
+
+    * Deprecated syntax
+          o colon (:) instead of "then" in if/unless or case expression.
+          o retry in a loop or an iterator.
+
+* builtin classes and objects
+
+    * Kernel and Object
+          o Kernel#methods and #singleton_methods used to return an
+            array of strings but now they return an array of symbols.
+    * Class and Module
+          o Module#attr works as Module#attr_reader by default.
+	    Optional boolean argument is obsolete.
+          o Module#instance_methods, #private_instance_methods and
+            #public_instance_methods used to return an array of
+            strings but now they return an array of symbols.
+          o Extra subclassing check when binding UnboundMethods
+
+    * Exceptions
+          o Exceptions are equal to each other if they belong to
+            the same class and have the same message and backtrace.
+          o SystemStackError used to be a subclass of StandardError
+            but not it is a direct subclass of Exception.
+          o SecurityError: ditto
+          o Removed Exception#to_str [Ruby2]
+
+    * Enumerable and Enumerator
+          o Enumerable::Enumerator, compatibility alias of Enumerator,
+            is removed.
+          o Enumerable#{map,collect} called without a block returns
+            an enumerator.
+          o Even more builtin and bundled libraries have been made to
+            return an enumerator when called without a block.
+    * Array
+          o Array#nitems was removed (use count {|i| !i.nil?})
+          o Array#choice was removed (use sample)
+          o Array#[m,n] = nil places nil in the array.
+    * Hash
+          o Hash#to_s is equivalent to Hash#inspect
+          o Semantics for Hash#each and Hash#each_pair
+          o Hash#select returns a hash
+          o Hash#key is the new name for #index which has been
+            deprecated.
+          o Hash preserves order.  It enumerates its elements in the
+            order in which the keys are inserted.
+          o Most of the changes in Hash apply to hash like interfaces
+            such as ENV and *DBM.
+    * IO operations
+          o Many methods used to act byte-wise but now some of those act
+            character-wise. You can use alternate byte-wise methods.
+          o IO#getc
+          o Non-blocking IO
+          o Kernel#open takes "t" for newline conversion
+          o Kernel#open takes encoding specified
+          o IO automatically converts byte sequence from a character
+            encodings into another if specified.
+          o StringIO#readpartial
+          o IO.try_convert
+          o IO.binread
+          o IO.copy_stream
+          o IO#binmode?
+          o IO#close_on_exec= and IO#close_on_exec?
+          o Limit input in IO#gets, IO#readline, IO#readlines,
+            IO#each_line, IO#lines, IO.foreach, IO.readlines,
+            StringIO#gets, StringIO#readline, StringIO#each,
+            StringIO#readlines
+          o IO#ungetc, StringIO#ungetc
+          o IO#ungetbyte, StringIO#ungetbyte
+          o IO#internal_encoding, IO#external_encoding,
+            IO#set_encoding
+          o IO.pipe takes encoding option
+          o Directive %u behaves like %d for negative values in
+            printf-style formatting.
+    * File and Dir operations
+          o #to_path is called as necessary in File.path, File.chmod,
+            File.lchmod, File.chown, File.lchown, File.utime,
+            File.unlink, etc..
+          o File.world_readable?
+          o File.world_writable?
+          o Dir.[], Dir.glob
+          o Dir.exist?
+          o Dir.exists?
+    * File::Stat
+          o File::Stat#world_readable?
+          o File::Stat#world_writable?
+    * String
+          o No longer an Enumerable: use each_line/lines for line
+            oriented operation
+          o Encoding-awareness
+              o Character-wise semantics in many methods instead of
+                byte-wise.
+                  o String#[]: Indexing a String with an integer returns a
+                    single character String instead of an integer.
+                  o String#[]=: No longer takes an integer as right
+                    side value.  Note that "str[i] = ?c" because of
+                    the following change.
+                  o ?c is evaluated to a single character string
+                    instead of an integer.
+    * Regexp
+          o Encoding-awareness
+          o Regexp matches only with strings which is encoded in a
+            compatible character encoding to the regexp's.
+          o Regexp#kcode is removed. use Regexp#encoding.
+    * Symbols: restriction on literal symbols
+    * Numeric
+          o Numeric#div always rounds as Integer#div has done.
+          o Numeric#fdiv: ditto.
+    * Integer
+          o Integer(nil) raises TypeError
+    * Fixnum
+          o Fixnum#id2name removed
+          o Fixnum#to_sym removed
+    * Struct
+          o Struct#inspect

+          o Kernel#to_a
+          o Kernel#getc, #gsub, #sub

+            and come back in future version.
+          o Symbol#to_int and Symbol#to_i
+          o $KCODE is no longer effective.  Use Encoding related
+            features of each class.
+          o VERSION and friends
+
+* bundled libraries
+
+    * Pathname
+          o No longer has #to_str nor #=~.
+    * time and date
+          o Time.parse and Date.parse interprets slashed numerical dates
+	    as "dd/mm/yyyy".
+    * Readline
+          o If Readline uses libedit, Readline::HISTORY[0] returns the
+            first of the history.
+    * Continuation
+          o as above
+

+          o Win32API library: use dl.
+          o dl library: Reimplemented and API changed. use the new
+	    version of dl or ffi gem.

+= NEWS for Ruby 1.9.3
+
+This document is a list of user visible feature changes made between
+releases except for bug fixes.
+
+Note that each entry is kept so brief that no reason behind or
+reference information is supplied with.  For a full list of changes
+with all sufficient information, see the ChangeLog file.
+
+== Changes since the 1.9.2 release
+=== License
+
+* Ruby's License is changed from a dual license with GPLv2
+  to a dual license with 2-clause BSDL.
+
+=== Known platform dependent issues
+==== OS X Lion
+
+* You have to configure ruby with '--with-gcc=gcc-4.2' if you're using
+  Xcode 4.1, or, if you're using Xcode 4.2, you have to configure ruby
+  with '--with-gcc=clang'.
+
+=== C API updates
+
+* rb_scan_args() is enhanced with support for option hash argument
+  extraction.
+
+* ruby_vm_at_exit() added.  This enables extension libs to hook a VM
+  termination.
+
+* rb_reserved_fd_p() added.  If you want to close all file descriptors,
+  check using this API.  [ruby-core:37759]
+
+=== Library updates (outstanding ones only)
+
+* builtin classes
+
+  * ARGF
+    * new methods:
+      * ARGF.print
+      * ARGF.printf
+      * ARGF.putc
+      * ARGF.puts
+      * ARGF.read_nonblock
+      * ARGF.to_write_io
+      * ARGF.write
+
+  * Array
+    * extended method:
+      * Array#pack supports endian modifiers
+
+  * Bignum
+    * Multiplication algorithm for Bignums with a large number of digits over
+      150 BDIGITs is changed in order to reduce its calculation time.
+      Now such large Bignums are multiplied by using Toom-3 algorithm.
+
+  * Encoding
+    * new encodings:
+      * CP950
+      * CP951
+      * UTF-16
+      * UTF-32
+    * change alias:
+      * SJIS is Windows-31J
+
+  * File
+    * new constant:
+      * File::NULL
+        name of NULL device.
+      * File::DIRECT
+        name of O_DIRECT.
+
+  * IO
+    * extended method:
+      * IO#putc supports multibyte characters
+    * new methods:
+      * IO#advise
+      * IO.write(name, string, [offset] )
+        Write `string` to file `name`.
+        Opposite with File.read.
+      * IO.binwrite(name, string, [offset] )
+        binary version of IO.write.
+
+  * Kernel
+    * move #__id__ to BasicObject.
+    * extended method:
+      * Kernel#rand supports range argument
+
+  * Module
+    * new methods:
+      * Module#private_constant
+      * Module#public_constant
+
+  * Random
+    * extended method:
+      * Random.rand supports range argument
+
+  * String
+    * extended method:
+      * String#unpack supports endian modifiers
+    * new method:
+      * String#prepend
+      * String#byteslice
+
+  * Time
+    * extended method:
+      * Time#strftime supports %:z and %::z.
+
+  * Process
+    * Process#maxgroups and Process#maxgroups= now raise NotImplementedError if
+      the platform don't support supplementary groups concept.
+
+* bigdecimal
+
+  * BigDecimal#power and BigDecimal#** support non-integral exponent.
+
+  * Kernel.BigDecimal and BigDecimal.new now accept instances of Integer,
+    Rational, Float, and BigDecimal.  If you pass a Rational or a Float to
+    them, you must specify the precision to produce the digits of a BigDecimal.
+
+  * The behavior of BigDecimal#coerce with a Rational is changed.  It uses
+    the precision of the receiver BigDecimal to produce the digits of a
+    BigDecimal from the given Rational.
+
+* bigdecimal/util
+
+  * BigDecimal#to_d and Integer#to_d are added.
+
+  * Float#to_d accepts a precision.
+
+  * Rational#to_d raises ArgumentError when passing zero or negative
+    precision.
+
+  * Rational#to_d
+
+    * Zero and an implicit precision is deprecated.
+      This feature is removed at the next release of bigdecimal.
+
+    * A negative precision isn't supported.
+      Be careful it is an incompatible change.
+
+* date
+
+  * Accepts flonum explicitly with limitations.
+    * If the given offset is flonum, DateTime assumes its precision is
+      at most second.
+
+      DateTime.new(2001,2,3,0,0,0,3.0/24) ==
+      DateTime.new(2001,2,3,0,0,0,'+03:00')
+        #=> true
+
+    * If the given operand for -/+ is flonum, DateTime assumes its
+      precision is at most nanosecond.
+
+      DateTime.new(2001,2,3) + 0.5 == DateTime.new(2001,2,3,12)
+        #=> true
+
+    * Precision of offset is always at most second.
+
+      Rational('0.5') == Rational('0.500001')  #=> false
+      DateTime.new(2001,2,3,0,0,0,Rational('0.5')) ==
+      DateTime.new(2001,2,3,0,0,0,Rational('0.500001'))
+        #=> true
+
+  * Ignores long offset and far reform day (with warning).
+
+    * Now accepts only:
+
+      -1<=offset<=1 (-24:00..+24:00)
+      2298874<=start<=2426355 or -/+oo
+        (proleptic Gregorian/Julian mean -/+oo)
+
+  * A method strftime cannot produce huge output (same as Time's one).
+
+    * Even though Date/DateTime can handle far dates, the following causes
+      an exception.
+
+      DateTime.new(1<<10000).strftime('%Y')  # Errno::ERANGE
+
+  * Changed the format of inspect.
+  * Changed the format of marshal (but, can load old dumps).
+
+* io/console
+  * new methods:
+    * IO#noecho {|io| }
+    * IO#echo=
+    * IO#echo?
+    * IO#raw {|io| }
+    * IO#raw!
+    * IO#getch
+    * IO#winsize
+    * IO.console
+
+* json
+  * updated to v1.5.4.
+
+* matrix
+  * new classes:
+    * Matrix::EigenvalueDecomposition
+    * Matrix::LUPDecomposition
+  * new methods:
+    * Matrix#diagonal?
+    * Matrix#eigen
+    * Matrix#eigensystem
+    * Matrix#hermitian?
+    * Matrix#lower_triangular?
+    * Matrix#lup
+    * Matrix#lup_decomposition
+    * Matrix#normal?
+    * Matrix#orthogonal?
+    * Matrix#permutation?

+    * Vector#normalize
+  * extended methods:
+    * Matrix#each and #each_with_index can iterate on a subset of the elements
+    * Matrix#find_index returns [row, column] and can iterate on a subset
+      of the elements
+    * Matrix#** implements Numeric exponents (using the eigensystem)
+    * Matrix.zero can build rectangular matrices
+
+* minitest
+  * Minitest has been updated to version 2.2.2.
+  * For full details, see https://github.com/seattlerb/minitest/blob/master/History.txt
+
+* net/http
+  * SNI (Server Name Indication) supported for HTTPS.
+
+  * Allow to configure to wait server returning '100 continue' response
+    before sending HTTP request body. Set Net::HTTP#continue_timeout AND pass
+    'expect' => '100-continue' to a extra HTTP header.
+
+    For example, the following code sends HTTP header and waits for getting
+    '100 continue' response before sending HTTP request body. When 0.5 [sec]
+    timeout occurs or the server send '100 continue', the client sends HTTP
+    request body.
+      http.continue_timeout = 0.5

+    ensured by (already existing) fallbacks during creation.
+  * OpenSSL::ASN1::Constructive#new and OpenSSL::ASN1::Primitive#new

+    * added LoadError#path method to return the file name that could not be
+      loaded.
+
+* Module
+  * added method:

+      the same object.
+
+* Process

+    * added getsid for getting session id (unix only).
+
+* Range
+  * added method:

+    * added Range#bsearch for binary search.
+
+* RubyVM (MRI specific)

+    from a method or a block.
+  * added RubyVM::InstructionSequence#path, #absolute_path, #label,
+    #base_label and #first_lineno to retrieve information from where
+    the instruction sequence was defined.
+  * added Environment variables to specify stack usage:
+    * RUBY_THREAD_VM_STACK_SIZE: vm stack size used at thread creation.
+      default: 128KB (32bit CPU) or 256KB (64bit CPU).

+      are specified.
+
+* String
+  * added method:

+      instance variable names.
+
+* Thread
+  * added method:
+    * added Thread#thread_variable_get for getting thread local variables
+      (these are different than Fiber local variables).

+    * added Thread#backtrace_locations which returns similar information of
+      Kernel#caller_locations.
+  * new class Thread::Backtrace::Location to hold backtrace location
+    information. These are returned by Thread#backtrace_locations and
+    Kernel#caller_locations.
+  * incompatible changes:
+    * Thread#join and Thread#value now raises a ThreadError if target thread
+      is the current or main thread.
+
+* Time
+  * change return value:

+
+* toplevel
+  * added method:
+    * added main.define_method which defines a global function.
+    * added main.using, which imports refinements into the current file or
+      eval string. [experimental]
+
+=== Core classes compatibility issues (excluding feature bug fixes)
+
+* Array#values_at
+
+  See above.
+
+* String#lines
+* String#chars
+* String#codepoints
+* String#bytes
+
+  These methods no longer return an Enumerator, although passing a
+  block is still supported for backwards compatibility.
+
+  Code like str.lines.with_index(1) { |line, lineno| ... } no longer
+  works because str.lines returns an array.  Replace lines with
+  each_line in such cases.
+
+* IO#lines
+* IO#chars
+* IO#codepoints
+* IO#bytes
+* ARGF#lines
+* ARGF#chars
+* ARGF#bytes
+* StringIO#lines
+* StringIO#chars
+* StringIO#codepoints
+* StringIO#bytes
+* Zlib::GzipReader#lines
+* Zlib::GzipReader#bytes
+
+  These methods are deprecated in favor of each_line, each_byte,
+  each_char and each_codepoint.
+
+* Proc#==
+* Proc#eql?
+
+  These methods were removed. Two procs are == only when they are
+  the same object.
+
+* Fixnum
+* Bignum
+* Float
+
+  Fixnums, Bignums and Floats are frozen.
+
+* Signal.trap
+
+  See above.
+
+* Merge Onigmo.
+  https://github.com/k-takata/Onigmo
+
+* The :close_others option is true by default for system() and exec().
+  Also, the close-on-exec flag is set by default for all new file descriptors.
+  This means file descriptors doesn't inherit to spawned process unless
+  explicitly requested such as system(..., fd=>fd).
+
+* Kernel#respond_to? against a protected method now returns false
+  unless the second argument is true.
+
+* Kernel#respond_to_missing?
+* Kernel#initialize_clone
+* Kernel#initialize_dup
+
+  These methods are now private.
+
+* Thread#join, Thread#value
+
+  See above.
+
+* Mutex#lock, Mutex#unlock, Mutex#try_lock, Mutex#synchronize and Mutex#sleep
+
+  See above.
+
+=== Stdlib updates (outstanding ones only)
+
+* cgi
+  * Add HTML5 tag maker.
+  * CGI#header has been renamed to CGI#http_header and
+    aliased to CGI#header.
+  * When HTML5 tagmaker called, overwrite CGI#header,
+    CGI#header function is to create a <header> element.
+
+* CSV
+  * Removed CSV::dump and CSV::load to protect users from dangerous
+    serialization vulnerability
+
+* iconv
+  * Iconv has been removed. Use String#encode instead.
+
+* io/console
+  * new methods:
+    * added IO#cooked which sets the terminal to cooked mode within the given block.
+    * added IO#cooked! which sets the terminal to cooked.
+  * extended method:
+    * IO#raw, IO#raw!, and IO#getch accept keyword arguments, :min and :time.
+
+* io/wait
+  * new features:
+    * added IO#wait_writable method.
+    * added IO#wait_readable method as alias of IO#wait.
+
+* json
+  * updated to 1.7.7.
+
+* net/http
+  * new features:
+    * Proxies are now automatically detected from the http_proxy environment
+      variable.  See Net::HTTP::new for details.
+    * gzip and deflate compression are now requested for all requests by
+      default.  See Net::HTTP for details.
+    * SSL sessions are now reused across connections for a single instance.
+      This speeds up connection by using a previously negotiated session.
+    * Requests may be created from a URI which sets the request_uri and host
+      header of the request (but does not change the host connected to).
+    * Responses contain the URI requested which allows easier implementation of
+      redirect following.
+  * new methods:
+    * Net::HTTP#local_host
+    * Net::HTTP#local_host=
+    * Net::HTTP#local_port
+    * Net::HTTP#local_port=
+  * extended method:
+    * Net::HTTP#connect uses local_host and local_port if specified.
+
+* net/imap
+  * new methods:
+    * Net::IMAP.default_port
+    * Net::IMAP.default_imap_port
+    * Net::IMAP.default_tls_port
+    * Net::IMAP.default_ssl_port
+    * Net::IMAP.default_imaps_port
+
+* objspace
+  * new method:
+    * ObjectSpace.reachable_objects_from(obj)
+
+* openssl
+  * Consistently raise an error when trying to encode nil values. All instances
+    of OpenSSL::ASN1::Primitive now raise TypeError when calling to_der on an
+    instance whose value is nil. All instances of OpenSSL::ASN1::Constructive
+    raise NoMethodError in the same case. Constructing such values is still
+    permitted.
+  * TLS 1.1 & 1.2 support by setting OpenSSL::SSL::SSLContext#ssl_version to
+    :TLSv1_2, :TLSv1_2_server, :TLSv1_2_client or :TLSv1_1, :TLSv1_1_server
+    :TLSv1_1_client. The version being effectively used can be queried
+    with OpenSSL::SSL#ssl_version. Furthermore, it is also possible to
+    blacklist the new TLS versions with OpenSSL::SSL:OP_NO_TLSv1_1 and
+    OpenSSL::SSL::OP_NO_TLSv1_2.
+  * Added OpenSSL::SSL::SSLContext#renegotiation_cb. A user-defined callback
+    may be set which gets called whenever a new handshake is negotiated. This
+    also allows to programmatically decline (client) renegotiation attempts.
+  * Support for "0/n" splitting of records as BEAST mitigation via
+    OpenSSL::SSL::OP_DONT_INSERT_EMPTY_FRAGMENTS.
+  * The default options for OpenSSL::SSL::SSLContext have changed to
+    OpenSSL::SSL::OP_ALL & ~OpenSSL::SSL::OP_DONT_INSERT_EMPTY_FRAGMENTS
+    instead of OpenSSL::SSL::OP_ALL only. This enables the countermeasure for
+    the BEAST attack by default.
+  * OpenSSL requires passwords for decrypting PEM-encoded files to be at least
+    four characters long. This led to awkward situations where an export with
+    a password with fewer than four characters was possible, but accessing the
+    file afterwards failed. OpenSSL::PKey::RSA, OpenSSL::PKey::DSA and
+    OpenSSL::PKey::EC therefore now enforce the same check when exporting a
+    private key to PEM with a password - it has to be at least four characters
+    long.
+  * SSL/TLS support for the Next Protocol Negotiation extension. Supported
+    with OpenSSL 1.0.1 and higher.
+  * OpenSSL::OPENSSL_FIPS allows client applications to detect whether OpenSSL
+    is FIPS-enabled. OpenSSL.fips_mode= allows turning on and off FIPS mode
+    manually in order to adapt to situations where FIPS mode would be an
+    explicit requirement.
+  * Authenticated Encryption with Associated Data (AEAD) is supported via
+    Cipher#auth_data= and Cipher#auth_tag/Cipher#auth_tag=.
+    Currently (OpenSSL 1.0.1c), only GCM mode is supported.
+
+* ostruct
+  * new methods:
+    * OpenStruct#[], []=
+    * OpenStruct#each_pair
+    * OpenStruct#eql?
+    * OpenStruct#hash
+    * OpenStruct#to_h converts the struct to a hash.
+  * extended method:
+    * OpenStruct.new also accepts an OpenStruct / Struct.
+
+* pathname
+  * extended method:
+    * Pathname#find returns an enumerator if no block is given.
+
+* rake
+  * rake has been updated to version 0.9.5.
+
+    This version is backwards-compatible with previous rake versions and
+    contains many bug fixes.
+
+    See
+    http://rake.rubyforge.org/doc/release_notes/rake-0_9_5_rdoc.html for a list
+    of changes in rake 0.9.3, 0.9.4 and 0.9.5.
+
+* RDoc
+  * RDoc has been updated to version 4.0
+
+    This version is largely backwards-compatible with previous rdoc versions.
+    The most notable change is an update to the ri data format (ri data must
+    be regenerated for gems shared across rdoc versions).  Further API changes
+    are internal and won't affect most users.
+
+    Notable changes include:
+
+    * Page support for ri.  Try `ri ruby:` for a list of pages in ruby or
+      `ri ruby:syntax/literals` for the syntax documentation for literals.
+
+      This also works for gems such as `ri rspec:README` for the rspec gem's
+      README file.
+    * Markdown support.  See ri RDoc::Markdown for details.
+
+    See https://github.com/rdoc/rdoc/blob/master/History.rdoc for a full list
+    of changes in rdoc 4.0.
+
+* resolv
+  * new methods:
+    * Resolv::DNS#timeouts=
+    * Resolv::DNS::Config#timeouts=
+
+* rexml
+  * REXML::Document#write supports Hash arguments.
+  * REXML::Document#write supports new :encoding option. It changes
+    XML document encoding. Without :encoding option, encoding in
+    XML declaration is used for XML document encoding.
+
+* RubyGems
+  * Updated to 2.0.0
+
+    RubyGems 2.0.0 features the following improvements:
+
+    * Improved support for default gems shipping with ruby 2.0.0+
+    * A gem can have arbitrary metadata through Gem::Specification#metadata
+    * `gem search` now defaults to --remote and is anchored like gem list.
+    * Added --document to replace --rdoc and --ri.  Use --no-document to
+      disable documentation, --document=rdoc to only generate rdoc.
+    * Only ri-format documentation is generated by default.
+    * `gem server` uses RDoc::Servlet from RDoc 4.0 to generate HTML
+      documentation.
+
+    For an expanded list of updates and bug fixes see:
+    https://github.com/rubygems/rubygems/blob/master/History.txt
+
+* shellwords
+  * Shellwords#shellescape now stringifies the given object using to_s.
+  * Shellwords#shelljoin accepts non-string objects in the given
+    array, each of which is stringified using to_s.
+
+* stringio
+  * deprecated methods:
+    * StringIO#lines, #bytes, #chars and #codepoints are deprecated.
+
+* syslog
+  * Added Syslog::Logger which provides a Logger API atop Syslog.
+  * Syslog::Priority, Syslog::Level, Syslog::Option and Syslog::Macros
+    are introduced for easy detection of available constants on a
+    running system.
+
+* tmpdir
+  * incompatible changes:
+    * Dir.mktmpdir uses FileUtils.remove_entry instead of
+      FileUtils.remove_entry_secure.  This means that applications should not
+      change the permission of the created temporary directory to make
+      writable from other users.
+
+* yaml
+  * Syck has been removed.  YAML now completely depends on libyaml being
+    installed.
+  * libyaml is now bundled with ruby, for cases where the library is not
+    installed locally.
+
+* zlib
+  * Added streaming support for Zlib::Inflate and Zlib::Deflate.  This allows
+    processing of a stream without the use of large amounts of memory.
+  * Added support for the new deflate strategies Zlib::RLE and Zlib::FIXED.
+  * Zlib streams are now processed without the GVL.  This allows gzip, zlib and
+    deflate streams to be processed in parallel.
+  * deprecated methods:
+    * Zlib::GzipReader#lines and #bytes are deprecated.
+
+=== Stdlib compatibility issues (excluding feature bug fixes)
+
+* OpenStruct new methods can conflict with custom attributes named
+  "each_pair", "eql?", "hash" or "to_h".
+
+* Dir.mktmpdir in lib/tmpdir.rb
+
+  See above.
+
+=== C API updates
+
+* NUM2SHORT() and NUM2USHORT() added. They are similar to NUM2INT, but short.
+
+* rb_newobj_of() and NEWOBJ_OF() added. They create a new object of a given class.

+Note that each entry is kept so brief that no reason behind or
+reference information is supplied with.  For a full list of changes
+with all sufficient information, see the ChangeLog file.
+
+== Changes since the 2.0.0 release
+
+=== Language changes
+
+* Now the default values of keyword arguments can be omitted.  Those
+  "required keyword arguments" need giving explicitly at the call time.
+
+* Added suffixes for integer and float literals: 'r', 'i', and 'ri'.
+  * "42r" and "3.14r" are evaluated as Rational(42, 1) and 3.14.rationalize,
+    respectively.  But exponential form with 'r' suffix like "6.022e+23r" is
+    not accepted because it is misleading.
+  * "42i" and "3.14i" are evaluated as Complex(0, 42) and Complex(0, 3.14),
+    respectively.
+  * "42ri" and "3.14ri" are evaluated as Complex(0, 42r) and Complex(0, 3.14r),
+    respectively.
+
+* def-expr now returns the symbol of its name instead of nil.
+
+=== Core classes updates (outstanding ones only)
+
+* Array
+  * New methods
+    * Array#to_h converts an array of key-value pairs into a Hash.
+
+* Binding
+  * New methods
+    * Binding#local_variable_get(symbol)
+    * Binding#local_variable_set(symbol, obj)
+    * Binding#local_variable_defined?(symbol)
+
+* Enumerable
+  * New methods
+    * Enumerable#to_h converts a list of key-value pairs into a Hash.
+
+* Exception
+  * New methods
+    * Exception#cause provides the previous exception which has been caught
+      at where raising the new exception.
+
+* GC
+  * improvements:
+    * introduced the generational GC a.k.a RGenGC.
+  * added environment variables:
+    * RUBY_GC_HEAP_INIT_SLOTS
+    * RUBY_GC_HEAP_FREE_SLOTS
+    * RUBY_GC_HEAP_GROWTH_FACTOR
+    * RUBY_GC_HEAP_GROWTH_MAX_SLOTS
+    * RUBY_GC_MALLOC_LIMIT_MAX
+    * RUBY_GC_MALLOC_LIMIT_GROWTH_FACTOR
+    * RUBY_GC_OLDMALLOC_LIMIT
+    * RUBY_GC_OLDMALLOC_LIMIT_MAX
+    * RUBY_GC_OLDMALLOC_LIMIT_GROWTH_FACTOR
+  * obsoleted environment variables:
+    * RUBY_FREE_MIN (Use RUBY_GC_HEAP_FREE_SLOTS instead)
+    * RUBY_HEAP_MIN_SLOTS (Use RUBY_GC_HEAP_INIT_SLOTS instead)
+
+* Integer
+  * New methods
+    * Fixnum#bit_length
+    * Bignum#bit_length
+  * Bignum performance improvement
+    * Use GMP if available.
+      GMP is used only for several operations:
+      multiplication, division, radix conversion, GCD
+
+* IO
+  * extended methods:
+    * IO#seek supports SEEK_DATA and SEEK_HOLE as whence.
+    * IO#seek accepts symbols (:CUR, :END, :SET, :DATA, :HOLE) for 2nd argument.
+    * IO#read_nonblock accepts optional `exception: false` to return symbols
+    * IO#write_nonblock accepts optional `exception: false` to return symbols
+
+* Kernel
+  * New methods:
+    * Kernel#singleton_method
+
+* Module
+  * New methods:
+    * Module#using, which activates refinements of the specified module only
+      in the current class or module definition.
+    * Module#singleton_class? returns true if the receiver is a singleton class
+      or false if it is an ordinary class or module.
+  * extended methods:
+    * Module#refine is no longer experimental.
+    * Module#include and Module#prepend are now public methods.
+
+* Mutex
+  * misc
+    * Mutex#owned? is no longer experimental.
+
+* Numeric
+  * extended methods:
+    * Numeric#step allows the limit argument to be omitted, in which
+      case an infinite sequence of numbers is generated.  Keyword
+      arguments `to` and `by` are introduced for ease of use.
+      `by` can be 0, in which case the same value will be generated
+      indefinitely.
+
+* Process
+  * New methods:
+    * alternative methods to $0/$0=:
+      * Process.argv0() returns the original value of $0.
+      * Process.setproctitle() sets the process title without affecting $0.
+    * Process.clock_gettime
+    * Process.clock_getres
+
+* String
+  * "literal".freeze is now optimized to return the same object
+  * New methods:
+    * String#scrub and String#scrub! verify and fix invalid byte sequence.
+      If you want to use this function with older Ruby,
+      consider to use string-scrub.gem.
+
+* Symbol
+  * All symbols are now frozen.
+
+* pack/unpack (Array/String)
+  * Q! and q! directives for long long type if platform has the type.
+
+* toplevel
+  * extended methods:
+    * main.using is no longer experimental. The method activates refinements
+      in the ancestors of the argument module to support refinement
+      inheritance by Module#include.
+
+=== Core classes compatibility issues (excluding feature bug fixes)
+
+* Hash
+  * incompatible changes:
+    * Hash#reject will return plain Hash object in the future versions, that
+      is the original object's subclass, instance variables, default value,
+      and taintedness will be no longer copied, so now warnings are emitted
+      when called with such Hash.
+
+* IO
+  * incompatible changes:
+    * open ignore internal encoding if external encoding is ASCII-8BIT.
+
+* Kernel#eval, Kernel#instance_eval, and Module#module_eval.
+  * Copies the scope information of the original environment, which means
+    that private, protected, public, and module_function without arguments
+    do not affect the environment outside the eval string.
+    For example, `class Foo; eval "private"; def foo; end; end' doesn't make
+    Foo#foo private.
+
+* Kernel#untrusted?, untrust, and trust
+  * These methods are deprecated and their behavior is same as tainted?,
+    taint, and untaint, respectively.  If $VERBOSE is true, they show warnings.
+
+* Module#ancestors
+  * The ancestors of a singleton class now include singleton classes,
+    in particular itself.
+
+* Module#define_method and Object#define_singleton_method
+  * Now they return the symbols of the defined methods, not the methods/procs
+    themselves.
+
+* Numeric#quo
+  * Raises TypeError instead of ArgumentError if the receiver doesn't have
+    to_r method.
+
+* Proc
+  * Returning from lambda proc now always exits from the Proc, not from the
+    method where the lambda is created.  Returning from non-lambda proc exits
+    from the method, same as the former behavior.
+
+String
+  * If invalid: :replace is specified for String#encode, replace
+    invalid byte sequence even if the destination encoding equals to
+    the source encoding.
+
+=== Stdlib updates (outstanding ones only)
+
+* CGI::Util
+  * All class methods modulized.
+
+* Digest
+  * extended methods:
+    * Digest::Class.file takes optional arguments for its constructor
+
+* Matrix
+  * Added Vector#cross_product.
+
+* Net::SMTP
+  * Added Net::SMTP#rset to implement the RSET command
+
+* objspace
+  * new method:
+    * ObjectSpace.trace_object_allocations
+    * ObjectSpace.trace_object_allocations_start
+    * ObjectSpace.trace_object_allocations_stop
+    * ObjectSpace.trace_object_allocations_clear
+    * ObjectSpace.allocation_sourcefile
+    * ObjectSpace.allocation_sourceline
+    * ObjectSpace.allocation_class_path
+    * ObjectSpace.allocation_method_id
+    * ObjectSpace.allocation_generation
+    * ObjectSpace.reachable_objects_from_root
+    * ObjectSpace.dump
+    * ObjectSpace.dump_all
+
+* OpenSSL::BN
+  * extended methods:
+    * OpenSSL::BN.new allows Fixnum/Bignum argument.
+
+* open-uri
+  * Support multiple fields with same field name (like Set-Cookie).
+
+* Pathname
+  * New methods:
+    * Pathname#write
+    * Pathname#binwrite
+
+* rake
+  * Updated to 10.1.0.  Major changes include removal of the class namespace,
+    Rake::DSL to hold the rake DSL methods and removal of support for legacy
+    rake features.
+
+    For a complete list of changes since rake 0.9.6 see:
+
+    http://rake.rubyforge.org/doc/release_notes/rake-10_1_0_rdoc.html
+
+    http://rake.rubyforge.org/doc/release_notes/rake-10_0_3_rdoc.html
+
+* RbConfig
+  * New constants:
+    * RbConfig::SIZEOF is added to provide the size of C types.
+
+* RDoc
+  * Updated to 4.1.0.  Major enhancements include a modified default template
+  * and accessibility enhancements.
+
+    For a list of minor enhancements and bug fixes see:
+    https://github.com/rdoc/rdoc/blob/v4.1.0.preview.1/History.rdoc
+
+* Resolv
+  * New methods:
+    * Resolv::DNS.fetch_resource
+  * One-shot multicast DNS support
+  * Support LOC resources
+
+* REXML::Parsers::SAX2Parser
+  * Fixes wrong number of arguments of entitydecl event. Document of the event
+    says "an array of the entity declaration" but implementation passes two
+    or more arguments. It is an implementation bug but it breaks backward
+    compatibility.
+
+* REXML::Parsers::StreamParser
+  * Supports "entity" event.
+
+* REXML::Text
+  * REXML::Text#<< supports method chain like 'text << "XXX" << "YYY"'.
+  * REXML::Text#<< supports not "raw" mode.
+
+* Rinda::RingServer, Rinda::RingFinger
+  * Rinda now supports multicast sockets.  See Rinda::RingServer and
+    Rinda::RingFinger for details.
+
+* RubyGems
+  * Updated to 2.2.0.  Notable new features include:
+
+    * Gemfile or gem.deps.rb support including Gem.file.lock (experimental)
+    * Improved, iterative resolver (compared to RubyGems 2.1 and earlier)
+    * Support for a sharing a GEM_HOME across ruby platforms and versions
+
+    For a complete list of enhancements and bug fixes see:
+    https://github.com/rubygems/rubygems/tree/master/History.txt
+
+* Set
+  * New methods:
+    * Set#intersect?
+    * Set#disjoint?
+
+* Socket
+  * New methods:
+    * Socket.getifaddrs
+
+* StringScanner
+  * extended methods:
+    * StringScanner#[] supports named captures.
+
+* Syslog::Logger
+  * Added facility.
+
+* Tempfile
+  * New methods:
+    * Tempfile.create
+
+* Timeout
+  * The exception to terminate the given block can no longer be rescued
+    inside the block, by default, unless the exception class is given
+    explicitly.
+
+* TSort
+  * New methods:
+    * TSort.tsort
+    * TSort.tsort_each
+    * TSort.strongly_connected_components
+    * TSort.each_strongly_connected_component
+    * TSort.each_strongly_connected_component_from
+
+* WEBrick
+  * The body of a response may now be a StringIO or other IO-like that responds
+    to #readpartial and #read.
+
+* XMLRPC::Client
+  * New methods:
+    * XMLRPC::Client#http. It returns Net::HTTP for the client. Normally,
+      it is not needed. It is useful when you want to change minor HTTP client
+      options. You can change major HTTP client options by XMLRPC::Client
+      methods. You should use XMLRPC::Client methods for changing major
+      HTTP client options instead of XMLRPC::Client#http.
+
+=== Stdlib compatibility issues (excluding feature bug fixes)
+
+* Set
+  * incompatible changes:
+    * Set#to_set now returns self instead of generating a copy.
+
+* URI
+  * incompatible changes:
+    * URI.decode_www_form follows current WHATWG URL Standard.
+      It gets encoding argument to specify the character encoding.
+      It now allows loose percent encoded strings, but denies ;-separator.
+    * URI.encode_www_form follows current WHATWG URL Standard.
+      It gets encoding argument to convert before percent encode.
+      UTF-16 strings aren't converted to UTF-8 before percent encode by default.
+
+* curses
+  * Removed.
+    curses is now available as a gem.
+    See https://rubygems.org/gems/curses for details.
+
+=== Built-in global variables compatibility issues
+
+* $SAFE
+  * $SAFE=4 is obsolete.  If $SAFE is set to 4 or larger, an ArgumentError
+    is raised.
+
+=== C API updates
+
+* rb_gc_set_params() is deprecated. This is only used in Ruby internal.
+
+* rb_gc_count() added. This returns the number of times GC occurred.
+
+* rb_gc_stat() added. This allows access to specific GC.stat() values from C
+  without any allocation overhead.
+
+* rb_gc_latest_gc_info() added. This allows access to GC.latest_gc_info().
+
+* rb_postponed_job_register() added. Takes a function callback which is invoked
+  when the VM is in a consistent state, i.e. to perform work from a C signal
+  handler.
+
+* rb_profile_frames() added. Provides low-cost access to the current ruby stack
+  for callstack profiling.
+
+* rb_tracepoint_new() supports new internal events accessible only from C:
+  * RUBY_INTERNAL_EVENT_NEWOBJ
+  * RUBY_INTERNAL_EVENT_FREEOBJ
+  * RUBY_INTERNAL_EVENT_GC_START
+  * RUBY_INTERNAL_EVENT_GC_END_MARK
+  * RUBY_INTERNAL_EVENT_GC_END_SWEEP
+  * Note that you *can not* specify "internal events" with normal events
+    (such as RUBY_EVENT_CALL, RUBY_EVENT_RETURN) simultaneously.

+      mode for redirect from [:out, :err].
+
+* String

+
+* Enumerable
+  * Enumerable#slice_before's state management deprecated.
+  * Enumerable#chunk's state management deprecated.
+
+* GC
+  * incompatible changes:
+    * Rename GC.stat entries. [Feature #9924]
+      See https://docs.google.com/spreadsheets/d/11Ua4uBr6o0k-nORrZLEIIUkHJ9JRzRR0NyZfrhEEnc8/edit?usp=sharing

+      { **hash1, **hash2 } contains values of hash2 for duplicated keys.
+
+* IO
+  * incompatible changes:
+    * When flushing file IO with IO#flush, you cannot assume that the metadata
+      of the file is updated immediately.  On some platforms (especially
+      Windows), it is delayed until the filesystem load is decreased.
+      Use IO#fsync if you want to guarantee updating metadata.
+
+* Math
+  * incompatible changes:
+    * Math.log now raises Math::DomainError instead of returning NaN if the
+      base is less than 0, and returns NaN instead of -infinity if both of
+      two arguments are 0.
+    * Math.atan2 now returns values like as expected by C99 if both two
+      arguments are infinity.
+
+* Proc
+  * incompatible changes:
+    * ArgumentError is no longer raised when lambda Proc is passed as a
+      block, and the number of yielded arguments does not match the formal
+      arguments of the lambda, if just an array is yielded and its length
+      matches.
+
+* Process

+    mode for redirect from [:out, :err].
+    Before Ruby 2.2, it was opened in read mode.
+
+=== Stdlib updates (outstanding ones only)
+
+* Continuation
+  * callcc is obsolete. use Fiber instead.
+
+* Digest
+
+  * Digest() should now be thread-safe.  If you have a problem with
+    regard to on-demand loading under a multi-threaded environment,
+    preload "digest/*" modules on boot or use this method instead of
+    directly referencing Digest::*.
+  * Digest::HMAC has been removed just as previously noticed.

+      which is obtained by multiplying the first minor by (-1)**(row + column).
+    * Matrix#adjugate returns the adjugate of the matrix.
+    * hstack and vstack are new instance and class methods to stack matrices
+      horizontally and vertically.
+    * Matrix#laplace_expansion(row_or_column: num) returns the laplace_expansion
+      along the +num+ -th row or column.
+    * Vector.basis(size:, index:) returns the specified basis vector.
+    * Unary - and + added for Vector and Matrix.
+    * Vector#cross_product generalized to arbitrary dimensions.
+    * Vector#dot and #cross are aliases for #inner_product and #cross_product.
+    * Vector#angle_with returns the angle with its argument
+    * New instance and class method independent? to test linear independence.
+
+* Pathname
+  * Pathname#/ is aliased to Pathname#+.
+  * New methods:
+    * Pathname#birthtime
+

+* struct RBignum is hidden.  [Feature #6083]
+  Use rb_integer_pack and rb_integer_unpack instead.
+
+* struct RRational is hidden.  [Feature #9513]
+  Use rb_rational_num and rb_rational_den instead.
+
+* rb_big_new and rb_big_resize takes a size_t instead of long.
+
+* rb_num2long returns a long instead of SIGNED_VALUE.
+
+* rb_num2ulong returns an unsigned long instead of VALUE.
+
+* st hash table uses power-of-two sizes for speed [Feature #9425].
+  Lookups are 10-25% faster if using appropriate hash functions.
+  However, weaknesses in hash distribution can no longer be masked
+  by prime number-sized tables, so extensions may need to tweak
+  hash functions to ensure good distribution.
+
+* rb_sym2str() added. This is almost same as `rb_id2str(SYM2ID(sym))`
+  but not pinning a dynamic symbol.
+
+* rb_str_cat_cstr() added. This is same as `rb_str_cat2()`.
+
+* `rb_str_substr()` and `rb_str_subseq()` will share middle of a string,
+  but not only the end of a string, in the future.  Therefore, result
+  strings may not be NUL-terminated, `StringValueCStr()` is needed
+  calling to obtain a NUL-terminated C string.
+
+* rb_tracepoint_new() supports new internal events accessible only from C:
+  * RUBY_INTERNAL_EVENT_GC_ENTER
+  * RUBY_INTERNAL_EVENT_GC_EXIT
+    r47528
+
+* rb_hash_delete() now does not call the block given to the current method.
+
+* rb_extract_keywords() and rb_get_kwargs() exported.  See README.EXT
+  for details.
+
+=== Build system updates
+
+* jemalloc is optionally supported via `./configure --with-jemalloc`
+  jemalloc may be suitable when system malloc is slow or prone
+  to fragmentation.  [Feature #9113]
+
+=== Implementation changes
+
+* GC
+    * Most symbols which are returned by String#to_sym and
+      String#intern are GC-able [Feature #9634]
+    * Introduce incremental marking for major GC. [Feature #10137]
+    * Enable lazy sweep on GC caused by malloc().
+
+* VM
+    * Use frozen string literals for Hash#[] and Hash#[]=
+    * Fast keyword arguments passing [Feature #10440]
+    * Allow to receive huge splatted array by a rest argument [Feature #10440]
+
+* Process
+    * Process creation methods, such as spawn(), uses vfork() system call.
+      vfork() is faster than fork() when the parent process uses huge memory.

+= NEWS for Ruby 2.3.0
+
+This document is a list of user visible feature changes made between
+releases except for bug fixes.
+
+Note that each entry is kept so brief that no reason behind or
+reference information is supplied with.  For a full list of changes
+with all sufficient information, see the ChangeLog file or Redmine
+(e.g. <tt>https://bugs.ruby-lang.org/issues/$FEATURE_OR_BUG_NUMBER</tt>)
+
+== Changes since the 2.2.0 release
+
+=== Language changes
+
+* frozen-string-literal pragma:
+
+  * new pragma, frozen-string-literal has been experimentally introduced. [Feature #8976]
+  * besides, --enable/--disable=frozen-string-literal options also have
+    been introduced. [Feature #8976]
+  * command line options --debug or --debug=frozen-string-literal enable
+    additional debugging mode which shows created location with at frozen
+    object error (RuntimeError). [Feature #11725]
+
+* safe navigation operator:
+
+  * new method call syntax, `object&.foo', method #foo is called on
+    `object' if it is not nil. [Feature #11537]
+
+    This is similar to `try!' in Active Support, except:
+    * method name is syntactically required
+          obj.try! {} # valid
+          obj&. {}    # syntax error
+    * arguments are evaluated only if a call is made:
+          obj.try!(:foo, bar())  # bar() is always evaluated
+          obj&.foo(bar())        # bar() is conditionally evaluated
+    * attribute assignment is valid
+          obj&.attr += 1
+
+* the did_you_mean gem:
+
+  * When a NameError or NoMethodError occurs because of a typo in the name,
+    the did_you_mean gem automatically suggests other names similar to the
+    method name.
+
+      "Yuki".starts_with?("Y")
+      # => NoMethodError: undefined method `starts_with?' for "Yuki":String
+      #    Did you mean?  start_with?
+
+* indented here document:
+
+  * new string literal, here document starts with `<<~`.
+    refer doc/syntax/literals.rdoc for more details. [Feature #9098]

+    this flag means to permit deleting opened file on Windows, but currently
+    this affect only files opened as binary.  [Feature #11218]
+
+  * new option parameter `flags' is added.
+    this parameter is bitwise-ORed to oflags generated by normal mode argument. [Feature #11253]
+
+  * IO#advise no longer raises Errno::ENOSYS in cases where it was
+    detected at build time but not available at runtime.  [Feature #11806]
+
+* Kernel

+    initial_state argument.  [Feature #10958]
+    Use a local variable instead to maintain a state.
+
+* File::Stat
+  * On Windows File::Stat#ino always returned 0, but now returns
+    BY_HANDLE_FILE_INFORMATION.nFileIndexHigh/Low.  [Feature #11216]
+
+* Hash
+  * Hash#inspect doesn't raise error even if its content returns
+    a string which is not compatible with Encoding.default_external

+* Net::HTTP
+  * default value of Net::HTTP#open_timeout is now 60 (was nil).
+
+* Net::Telnet

+
+=== Built-in global variables compatibility issues
+
+* $SAFE
+  * $SAFE=2 and $SAFE=3 are obsolete.  If $SAFE is set to 2 or larger,
+    an ArgumentError is raised.  [Feature #5455]
+
+=== C API updates
+
+* rb_define_class_id_under() now raises a TypeError exception when the
+  class is already defined but its superclass does not match the given
+  superclass, as well as definitions in ruby level.
+
+* rb_timespec_now() is added to fetch current datetime as struct timespec. [Feature #11558]
+
+* rb_time_timespec_new() is added to create a time object with epoch,
+  nanosecond, and UTC/localtime/time offset arguments.  [Feature #11558]
+
+* rb_autoload() deprecated, use rb_funcall() instead.  [Feature #11664]
+
+* rb_compile_error_with_enc(), rb_compile_error(), and rb_compile_bug()
+  deprecated.  these functions are exposed but only for internal use.
+  external libraries should not use them.
+
+=== Supported platform changes
+
+* OS/2 is no longer supported
+
+* BeOS is no longer supported
+
+* Borland-C is no longer supported
+
+* Haiku now stable and best effort
+
+=== Implementation improvements
+
+* Optimize Proc#call to eliminate method frame construction. [Feature #11569]
+
+* Reconsidering method entry data structure. [Bug #11278]
+
+* Introducing new table data structure for ID keys tables used by
+  method table and so on. New table structure is simple and fast
+  than st_table. [Feature #11420]
+
+* Machine code level tuning for object allocation and method calling
+  code. r52099, r52254
+
+* RubyVM::InstructionSequence is extended for future improvement. [Feature #11788]
+
+* Case dispatch is now optimized for all special constant literals
+  including nil, true, and false.  Previously, only literal strings,
+  symbols, integers and floats compiled to optimized case dispatch. [Feature #11769]
+
+* Instance variables on non-pure Ruby classes (T_DATA, T_FILE,
+  etc..) is less expensive to store than before. [Feature #11170]
+
+* All accesses to members of big Struct objects are performed in
+  constant-time.  Previously, Struct elements beyond the first 10
+  elements used a linear scan. [Feature #10585]
+
+* The Set class got several speed up. [Misc #10754], [r52591]
+
+* Socket and I/O-related improvements
+
+  * Calling overhead of most of new keyword-using I/O methods in
+    [Feature #11229] is reduced by avoiding the inefficient C API
+    to parse keywords.  [Feature #11339]
+
+  * The standard library is updated to use the improved
+    exception-free non-blocking I/O from [Feature #11229].
+    This has the additional benefit of quieter $DEBUG output in
+    addition to reducing expensive exceptions. [Feature #11044]
+
+  * (Linux-only) waiting on a single FD anywhere in the stdlib no longer
+    uses select(2), making it immune to slowdowns with high-numbered
+    FDs. [Feature #11081] [Feature #11377]
+
+* CGI.escapeHTML is optimized with C extension.

+  * Symbol#match now returns MatchData.  [Bug #11991]
+
+  * Symbol#match? [Feature #12898]
+
+  * Symbol#upcase, Symbol#downcase, Symbol#capitalize, and Symbol#swapcase now
+    work for all of Unicode. See the documentation of String#downcase
+    for details. [Feature #10085]
+
+* Thread
+
+  * Thread#report_on_exception and Thread.report_on_exception [Feature #6647]
+
+* TracePoint
+
+  * TracePoint#callee_id [Feature #12747]
+
+* Warning
+
+  * New module named Warning is introduced.  By default it has only
+    one singleton method, named warn.  This makes it possible for
+    3rd-party libraries to control the way warnings are handled. [Feature #12299]
+
+=== Stdlib updates (outstanding ones only)
+
+* CGI
+
+  * Don't allow , as a separator [Bug #12791]
+
+* CSV
+
+  * Add a liberal_parsing option. [Feature #11839]
+
+* IPAddr

+
+* IRB
+
+  * Binding#irb: Start a REPL session like `binding.pry` at r56624.
+
+* Logger
+
+  * Allow specifying logger parameters in constructor such
+    as level, progname, datetime_format, formatter. [Feature #12224]

+* Net::FTP
+
+  * Support TLS (RFC 4217).
+  * Support hash style options for Net::FTP.new.
+  * Add a new optional argument pathname to Net::FTP#status.
+    Contributed by soleboxy. [GH-1478] [Feature #12965]
+
+* OpenSSL
+
+  * Includes Ruby/OpenSSL 2.0. OpenSSL has been extracted as a Gem and is
+    maintained at a separate repository now: https://github.com/ruby/openssl.
+    It still remains as a 'default gem'.  [Feature #9612]
+    Refer to ext/openssl/History.md for the full release note.
+
+* optparse
+
+  * Add an into option. [Feature #11191]
+
+* pathname
+
+  * New method: Pathname#empty? [Feature #12596]
+
+* Readline
+
+  * Readline.quoting_detection_proc and Readline.quoting_detection_proc= [Feature #12659]
+
+* REXML
+
+  * REXML::Element#[]: If String or Symbol is specified, attribute
+    value is returned. Otherwise, Nth child is returned. This is
+    backward compatible change.
+
+* set
+
+  * New methods: Set#compare_by_identity and Set#compare_by_identity?. [Feature #12210]
+
+* WEBrick
+
+  * Don't allow , as a separator [Bug #12791]
+
+=== Compatibility issues (excluding feature bug fixes)
+
+* Array#sum and Enumerable#sum are implemented.  [Feature #12217]
+
+  Ruby itself has no compatibility problem because Ruby didn't have sum method
+  for arrays before Ruby 2.4.
+  However many third party gems, activesupport, facets, simple_stats, etc,
+  defines sum method.  These implementations are mostly compatible but
+  there are subtle differences.
+  Ruby's sum method should be mostly compatible but it is impossible to
+  be perfectly compatible with all of them.
+
+* Fixnum and Bignum are unified into Integer  [Feature #12005]
+
+  Fixnum class and Bignum class is removed.
+  Integer class is changed from abstract class to concrete class.
+  For example, 0 is an instance of Integer: 0.class returns Integer.
+  The constants Fixnum and Bignum is bound to Integer.
+  So obj.kind_of?(Fixnum) works as obj.kind_of?(Integer).
+  At C-level, Fixnum object and Bignum object should be distinguished by
+  FIXNUM_P(obj) and RB_TYPE_P(obj, T_BIGNUM).
+  RUBY_INTEGER_UNIFICATION can be used to detect this feature at C-level.
+  0.class == Integer can be used to detect this feature at Ruby-level.
+  The C-level constants, rb_cFixnum and rb_cBignum, are removed.
+  They can cause compilation failure.
+
+* String/Symbol#upcase/downcase/swapcase/capitalize(!) now work for all of
+  Unicode, not only for ASCII. [Feature #10085]
+
+  No change is needed if the data is in ASCII anyway or if the limitation
+  to ASCII was only tolerated while waiting for a more extensive implementation.
+  A change (using the :ascii option) is needed in cases where Unicode data
+  is processed, but the operation has to be limited to ASCII only.
+  A good example of this are internationalized domain names.
+
+* TRUE / FALSE / NIL
+
+  These constants are now obsoleted. [Feature #12574]
+  Use true / false / nil resp. instead.
+
+=== Stdlib compatibility issues (excluding feature bug fixes)
+
+* DateTime
+
+  * DateTime#to_time now preserves timezone.  [Bug #12189]
+
+* Psych
+
+  * Update to Psych 2.2.2
+
+* RDoc
+
+  * Update to RDoc 5.0.0
+
+* RubyGems
+
+  * Update to RubyGems 2.6.8
+
+* shellwords
+
+  * Shellwords.shellwords (shellsplit) treats the backslash as escape
+    character only when followed by one of the following characters:
+    $ ` " \ <newline> [Bug #10055]
+
+* Time
+
+  * Time#to_time now preserves timezone.  [Bug #12271]
+
+* thread
+
+  * the extension library is removed.  Till 2.0 it was a pure ruby script
+    "thread.rb", which has precedence over "thread.so", and has been provided
+    in $LOADED_FEATURES since 2.1.
+
+* Tk
+
+  * Tk is removed from stdlib.  [Feature #8539]
+
+    https://github.com/ruby/tk is the new upstream.
+
+* XMLRPC
+
+  * XMLRPC is removed from stdlib, and bundled as gem. [Feature #12160][ruby-core:74239]
+
+    https://github.com/ruby/xmlrpc is the new upstream.
+
+* Zlib
+
+  * Zlib.gzip and Zlib.gunzip [Feature #13020]
+
+=== C API updates
+
+* ruby_show_version() will no longer exits the process, if
+  RUBY_SHOW_COPYRIGHT_TO_DIE is set to 0.  This will be the default in
+  the future.
+
+* rb_gc_adjust_memory_usage() [Feature #12690]
+
+=== Supported platform changes
+
+* FreeBSD < 4 is no longer supported
+
+=== Implementation improvements
+
+* In some condition, `[x, y].max` and `[x, y].min` are optimized
+  so that a temporal array is not created.  The concrete condition is
+  an implementation detail: currently, the array literal must have no
+  splat, must have at least one expression but literal, the length must
+  be <= 0x100, and Array#max and min must not be redefined.  It will work
+  in most casual and real-life use case where it is written with intent
+  to `Math.max(x, y)`.
+
+* Thread deadlock detection now shows their backtrace and dependency. [Feature #8214]
+
+* st_table (st.c) internal data structure is improved. [Feature #12142]
+
+* Rational is extensively optimized. [Feature #12484]
+
+=== Miscellaneous changes
+
+* ChangeLog is removed from the repository.
+
+  It is generated from commit messages in Subversion by `make dist`.
+  Also note that now people should follow Git style commit message.
+  The template is written at {Short (50 chars or less) summary of
+  changes}[https://git-scm.com/book/ch5-2.html].  [Feature #12283]

+=== Stdlib updates (outstanding ones only)
+
+* BigDecimal
+
+  * Update to BigDecimal 1.3.4
+
+  * The following features are added:
+
+    * BigDecimal::VERSION
+
+  * The following features have been deprecated,
+    and are planned to be removed in the version 1.4.0:
+
+    * BigDecimal.new
+
+    * BigDecimal.ver
+
+  * BigDecimal#clone and #dup now do not make a new instance,
+    but returns the receiver itself.
+
+* Coverage
+
+  * Support branch coverage and method coverage measurement. [Feature #13901]
+    Branch coverage tells you which branches are executed, and which not.
+    Method coverage tells you which methods are invoked, and which not.
+    By running a test suite with this new feature, you can know which branches
+    and methods are executed by a test, and evaluate total coverage of a test
+    suite more strictly.
+
+    You can specify the measuring target by an option to `Coverage.start`:
+
+        Coverage.start(lines: true, branches: true, methods: true)
+
+    After some Ruby files are loaded, you can use `Coverage.result` to get
+    the coverage result:
+
+        Coverage.result
+        #=> { "/path/to/file.rb"=>
+        #     { :lines => [1, 2, 0, nil, ...],
+        #       :branches =>
+        #         { [:if, 0, 2, 1, 6, 4] =>
+        #             { [:then, 1, 3, 2, 3, 8] => 0,
+        #               [:else, 2, 5, 2, 5, 8] => 2
+        #             }
+        #         },
+        #       :methods => {
+        #          [Object, :foo, 1, 0, 7, 3] => 2
+        #       }
+        #     }
+        #   }
+
+    The result type of line coverage is not changed; it is just an array that
+    contains numbers, which means the count that each line was executed,
+    or `nil`s, which means that the line is not relevant.
+
+    The result type of branch coverage is:
+
+        { (jump base) => { (jump target) => (counter) } }
+
+    where jump base and targets have the format
+
+        [type, unique-id, start lineno, start column, end lineno, end column]
+
+    For example, `[:if, 0, 2, 1, 6, 4]` reads an `if` statement that ranges from
+    line 2 and column 1, to line 6 and column 4.  `[:then, 1, 3, 2, 3, 8]` reads
+    a `then` clause that ranges from line 3 and column 2, to line 3 and column 8.
+    Note that lineno starts from 1, and that columnno starts from 0.  So, the
+    above example shows a branch from the `if` to the `then` was never executed,
+    and a branch from the `if` to the `else` was executed twice.
+
+    The result type of method coverage is:
+
+        { (method key) => (counter) }
+
+    where method key has the format
+
+        [class, method-name, start lineno, start column, end lineno, end column]
+
+    For example, `[Object, :foo, 1, 0, 7, 3]` reads `Object#foo` that ranges from
+    line 1 and column 0, to line 7 and column 3.  The above example shows this
+    `Object#foo` was invoked twice.
+
+    Note: To keep compatibility, passing no option to `Coverage.start` will measure
+    only line coverage, and `Coverage.result` will return the old format:
+
+        Coverage.result
+        #=> { "/path/to/file.rb"=> [1, 2, 0, nil, ...] }
+
+* DRb
+
+  * ACL::ACLEntry.new no longer suppresses IPAddr::InvalidPrefixError.
+
+* ERB
+
+  * Add ERB#result_with_hash to render a template with local variables passed
+    with a Hash object. [Feature #8631]
+
+  * Default template file encoding is changed from ASCII-8BIT to UTF-8 in erb
+    command. [Bug #14095]
+
+  * Carriage returns are changed to be trimmed properly if trim_mode is specified
+    and used. Duplicated newlines will be removed on Windows. [Bug #5339] [Bug #11464]
+
+* IPAddr
+
+  * IPAddr no longer accepts invalid address mask. [Bug #13399]
+  * IPAddr#ipv4_compat and IPAddr#ipv4_compat? are marked for deprecation. [Bug #13769]
+
+  * New methods:
+
+    * IPAddr#prefix
+    * IPAddr#loopback?
+    * IPAddr#private? [Feature #11666]
+    * IPAddr#link_local? [Feature #10912]
+
+* IRB
+
+  * Print backtrace and error message in reverse order [Feature #8661] [experimental]
+  * `binding.irb` automatically requires irb and runs [Bug #13099] [experimental]
+  * `binding.irb` on its start shows source around the line where it was called [Feature #14124]
+
+* Matrix
+
+  * New methods:
+
+    * Matrix.combine and Matrix#combine [Feature #10903]
+    * Matrix#hadamard_product and Matrix#entrywise_product
+
+* Net::HTTP
+
+  * Net::HTTP.new supports no_proxy parameter [Feature #11195]
+  * Net::HTTP#min_version and Net::HTTP#max_version [Feature #9450]
+  * Add more HTTP status classes
+  * Net::HTTP::STATUS_CODES is added as HTTP Status Code Repository [Misc #12935]
+  * Net::HTTP#proxy_user and Net::HTTP#proxy_pass reflect http_proxy environment
+    variable if the system's environment variable is multiuser safe. [Bug #12921]
+
+* open-uri
+  * URI.open method defined as an alias to open-uri's Kernel.open.
+    open-uri's Kernel.open will be deprecated in future.
+
+* OpenSSL
+
+  * Updated Ruby/OpenSSL from version 2.0 to 2.1. Changes are noted in
+    "Version 2.1.0" section in ext/openssl/History.md.

+
+  * New method:
+
+    * Pathname#glob [Feature #7360]
+

+= NEWS for Ruby 2.6.0
+
+This document is a list of user visible feature changes made between
+releases except for bug fixes.
+
+Note that each entry is kept so brief that no reason behind or reference
+information is supplied with.  For a full list of changes with all
+sufficient information, see the ChangeLog file or Redmine
+(e.g. <tt>https://bugs.ruby-lang.org/issues/$FEATURE_OR_BUG_NUMBER</tt>)
+
+== Changes since the 2.5.0 release
+
+=== Language changes
+
+* <code>$SAFE</code> now is a process global state and can be set to 0 again. [Feature #14250]
+
+* Refinements take place at block passing.  [Feature #14223]
+
+* Refinements take place at Kernel#public_send.  [Feature #15326]
+
+* Refinements take place at Kernel#respond_to?.  [Feature #15327]
+
+* +else+ without +rescue+ now causes a syntax error.  [EXPERIMENTAL] [Feature #14606]
+
+* Constant names may start with a non-ASCII capital letter. [Feature #13770]
+
+* Endless ranges are introduced.  You can use a Range that has no end,
+  like <code>(0..)</code> (or similarly <code>(0...)</code>).  [Feature #12912]
+
+  The following shows typical use cases:
+
+    ary[1..]                              # identical to ary[1..-1]
+    (1...).each {|index| block }          # infinite loop from index 1
+    ary.zip(1..) {|elem, index| block }   # ary.each.with_index(1) { }
+
+* Non-Symbol keys in a keyword arguments hash cause an exception.
+
+* The "shadowing outer local variable" warning is removed.  [Feature #12490]
+
+  You can now write the following without warning:
+
+    user = users.find {|user| cond(user) }
+
+* Print +cause+ of the exception if the exception is not caught and printed
+  its backtraces and error message. [Feature #8257]
+
+* The flip-flop syntax is deprecated. [Feature #5400]
+
+=== Core classes updates (outstanding ones only)
+
+[Array]
+
+  [New methods]
+
+    * Added Array#union and Array#difference instance methods.  [Feature #14097]
+
+  [Modified method]

+    * Array#to_h now accepts a block that maps elements to new key/value pairs.  [Feature #15143]
+
+  [Aliased methods]
+
+    * Array#filter is a new alias for Array#select. [Feature #13784]
+    * Array#filter! is a new alias for Array#select!. [Feature #13784]
+
+[Binding]
+
+  [New method]
+
+    * Added Binding#source_location.  [Feature #14230]
+
+      This method returns the source location of the binding, a 2-element
+      array of <code>__FILE__</code> and <code>__LINE__</code>.
+      Traditionally, the same information could be retrieved by
+      <code>eval("[__FILE__, __LINE__]", binding)</code>, but we are
+      planning to change this behavior so that Kernel#eval ignores
+      binding's source location [Bug #4352].  So, users should use this
+      newly-introduced method instead of Kernel#eval.
+
+[Dir]
+
+  [New methods]
+
+    * Added Dir#each_child and Dir#children instance methods. [Feature #13969]

+    instance of this class from Numeric#step and Range#step.
+
+[Enumerator::Chain]
+
+  * This is a new class to represent a chain of enumerables that works as a
+    single enumerator, generated by such methods as Enumerable#chain and

+
+[Enumerator::Lazy]
+
+  [Aliased method]
+
+    * Enumerator::Lazy#filter is a new alias for

+
+  [Aliased methods]
+
+    * Hash#filter is a new alias for Hash#select.  [Feature #13784]
+
+    * Hash#filter! is a new alias for Hash#select!. [Feature #13784]
+
+[IO]
+
+  [New option]
+
+    * Added new mode character <code>'x'</code> to open files for exclusive
+      access. [Feature #11258]
+
+[Kernel]

+
+    * Kernel#system and Kernel#exec do not close non-standard file descriptors
+      (the default of the +:close_others+ option is changed to +false+,
+      but we still set the +FD_CLOEXEC+ flag on descriptors we
+      create).  [Misc #14907]
+
+[KeyError]
+
+  [New options]
+
+    * KeyError.new accepts +:receiver+ and +:key+ options to set receiver and
+      key in Ruby code.  [Feature #14313]

+  [Modified methods]
+
+    * Module#method_defined?, Module#private_method_defined?, and
+      Module#protected_method_defined? now accept the second
+      parameter as optional. If it is +true+ (the default value), it checks
+      ancestor modules/classes, or checks only the class itself. [Feature #14944]
+
+[NameError]
+
+  [New option]
+
+    * NameError.new accepts a +:receiver+ option to set receiver in Ruby
+      code.  [Feature #14313]

+    * Range#cover? now accepts a Range object. [Feature #14473]
+    * Range#step now returns an instance of the Enumerator::ArithmeticSequence

+  issues, see Compatibility issues section below for details.
+

+
+  [New options]
+
+    * Add +:oneshot_lines+ keyword argument to Coverage.start.
+
+    * Add +:stop+ and +:clear+ keyword arguments to Coverage.result.

+  * logger
+  * matrix
+  * mutex_m
+  * ostruct
+  * prime
+  * rexml
+  * rss
+  * shell
+  * sync
+  * thwait
+  * tracer
+
+[BigDecimal]
+
+  * The following methods are removed.
+
+    * BigDecimal.allocate
+    * BigDecimal.ver
+
+  * Every BigDecimal object is frozen. [Feature #13984]
+
+  * BigDecimal() parses the given string similar to Float().
+
+  * String#to_d parses the receiver string similar to String#to_f.
+
+  * BigDecimal.new will be removed in version 2.0.
+
+[Pathname]
+
+  * Pathname#read, Pathname#binread, Pathname#write, Pathname#binwrite,
+    Pathname#each_line and Pathname#readlines do not invoke external
+    commands even if the path starts with the pipe character <code>'|'</code>.
+    This follows [Feature #14245].
+
+=== Implementation improvements
+
+* Speedup Proc#call because we don't need to care about <code>$SAFE</code>
+  any more. [Feature #14318]
+
+  With +lc_fizzbuzz+ benchmark which uses Proc#call many times we can
+  measure x1.4 improvements.  [Bug #10212]
+
+* Speedup block.call where +block+ is passed block parameter. [Feature #14330]
+
+  Ruby 2.5 improves block passing performance. [Feature #14045]
+
+  Additionally, Ruby 2.6 improves the performance of passed block calling.
+
+* Introduce an initial implementation of a JIT (Just-in-time) compiler. [Feature #14235] [experimental]
+
+  * <tt>--jit</tt> command line option is added to enable JIT. <tt>--jit-verbose=1</tt>
+    is good for inspection.  See <tt>ruby --help</tt> for others.
+  * To generate machine code, this JIT compiler uses the C compiler used for building
+    the interpreter. Currently GCC, Clang, and Microsoft Visual C++ are supported for it.
+  * <tt>--disable-mjit-support</tt> option is added to configure. This is added for JIT debugging,
+    but if you get an error on building a header file for JIT, you can use this option to skip
+    building it as a workaround.
+  * rb_waitpid reimplemented on Unix-like platforms to maintain
+    compatibility with processes created for JIT [Bug #14867]
+
+* VM generator script renewal; makes the generated VM more optimized. [GH-1779]
+
+* Thread cache enabled for pthreads platforms (for Thread.new and
+  Thread.start).  [Feature #14757]
+
+* timer thread is eliminated for platforms with POSIX timers. [Misc #14937]
+
+* Transient Heap (theap) is supported. [Bug #14858] [Feature #14989]
+
+  theap is a managed heap for short-living memory objects. For example,
+  making a small and short-living Hash object is x2 faster. With rdoc benchmark,
+  we measured 6-7% performance improvement.
+
+* Native implementations (arm32, arm64, ppc64le, win32, win64, x86, amd64) of
+  coroutines to improve performance of Fiber significantly. [Feature #14739]
+
+=== Miscellaneous changes
+
+* On macOS, shared libraries no longer include a full version number of Ruby
+  in their names.  This eliminates the burden of each teeny upgrade on the
+  platform that users need to rebuild every extension library.

+
+== Changes since the 2.6.0 release
+
+=== Language changes
+
+==== Pattern matching
+
+* Pattern matching is introduced as an experimental feature. [Feature #14912]
+
+    case [0, [1, 2, 3]]
+    in [a, [b, *c]]
+      p a #=> 0
+      p b #=> 1
+      p c #=> [2, 3]
+    end
+
+    case {a: 0, b: 1}
+    in {a: 0, x: 1}
+      :unreachable
+    in {a: 0, b: var}
+      p var #=> 1
+    end
+
+    case -1
+    in 0 then :unreachable
+    in 1 then :unreachable
+    end #=> NoMatchingPatternError
+
+    json = <<END
+    {
+      "name": "Alice",
+      "age": 30,
+      "children": [{ "name": "Bob", "age": 2 }]
+    }
+    END
+
+    JSON.parse(json, symbolize_names: true) in {name: "Alice", children: [{name: name, age: age}]}
+
+    p name #=> "Bob"
+    p age  #=> 2
+
+    JSON.parse(json, symbolize_names: true) in {name: "Alice", children: [{name: "Charlie", age: age}]}
+    #=> NoMatchingPatternError
+
+* See the following slides for more details:
+  * https://speakerdeck.com/k_tsj/pattern-matching-new-feature-in-ruby-2-dot-7
+  * Note that the slides are slightly obsolete.
+
+* The warning against pattern matching can be suppressed with
+  {-W:no-experimental option}[#label-Warning+option].
+
+==== The spec of keyword arguments is changed towards 3.0
+
+* Automatic conversion of keyword arguments and positional arguments is
+  deprecated, and conversion will be removed in Ruby 3.  [Feature #14183]
+
+  * When a method call passes a Hash at the last argument, and when it
+    passes no keywords, and when the called method accepts keywords,
+    a warning is emitted.  To continue treating the hash as keywords,
+    add a double splat operator to avoid the warning and ensure
+    correct behavior in Ruby 3.
+
+      def foo(key: 42); end; foo({key: 42})   # warned
+      def foo(**kw);    end; foo({key: 42})   # warned
+      def foo(key: 42); end; foo(**{key: 42}) # OK
+      def foo(**kw);    end; foo(**{key: 42}) # OK
+
+  * When a method call passes keywords to a method that accepts keywords,
+    but it does not pass enough required positional arguments, the
+    keywords are treated as a final required positional argument, and a
+    warning is emitted.  Pass the argument as a hash instead of keywords
+    to avoid the warning and ensure correct behavior in Ruby 3.
+
+      def foo(h, **kw); end; foo(key: 42)      # warned
+      def foo(h, key: 42); end; foo(key: 42)   # warned
+      def foo(h, **kw); end; foo({key: 42})    # OK
+      def foo(h, key: 42); end; foo({key: 42}) # OK
+
+  * When a method accepts specific keywords but not a keyword splat, and
+    a hash or keywords splat is passed to the method that includes both
+    Symbol and non-Symbol keys, the hash will continue to be split, and
+    a warning will be emitted.  You will need to update the calling code
+    to pass separate hashes to ensure correct behavior in Ruby 3.
+
+      def foo(h={}, key: 42); end; foo("key" => 43, key: 42)   # warned
+      def foo(h={}, key: 42); end; foo({"key" => 43, key: 42}) # warned
+      def foo(h={}, key: 42); end; foo({"key" => 43}, key: 42) # OK
+
+  * If a method does not accept keywords, and is called with keywords,
+    the keywords are still treated as a positional hash, with no warning.
+    This behavior will continue to work in Ruby 3.
+
+      def foo(opt={});  end; foo( key: 42 )   # OK
+
+* Non-symbols are allowed as keyword argument keys if the method accepts
+  arbitrary keywords. [Feature #14183]
+
+  * Non-Symbol keys in a keyword arguments hash were prohibited in 2.6.0,
+    but are now allowed again.  [Bug #15658]
+
+      def foo(**kw); p kw; end; foo("str" => 1) #=> {"str"=>1}
+
+* <code>**nil</code> is allowed in method definitions to explicitly mark
+  that the method accepts no keywords. Calling such a method with keywords
+  will result in an ArgumentError. [Feature #14183]
+
+    def foo(h, **nil); end; foo(key: 1)       # ArgumentError
+    def foo(h, **nil); end; foo(**{key: 1})   # ArgumentError
+    def foo(h, **nil); end; foo("str" => 1)   # ArgumentError
+    def foo(h, **nil); end; foo({key: 1})     # OK
+    def foo(h, **nil); end; foo({"str" => 1}) # OK
+
+* Passing an empty keyword splat to a method that does not accept keywords
+  no longer passes an empty hash, unless the empty hash is necessary for
+  a required parameter, in which case a warning will be emitted.  Remove
+  the double splat to continue passing a positional hash.  [Feature #14183]
+
+    h = {}; def foo(*a) a end; foo(**h) # []
+    h = {}; def foo(a) a end; foo(**h)  # {} and warning
+    h = {}; def foo(*a) a end; foo(h)   # [{}]
+    h = {}; def foo(a) a end; foo(h)    # {}
+
+* Above warnings can be suppressed also with {-W:no-deprecated option}[#label-Warning+option].
+
+==== Numbered parameters
+
+* Numbered parameters as default block parameters are introduced. [Feature #4475]
+
+    [1, 2, 10].map { _1.to_s(16) }    #=> ["1", "2", "a"]
+    [[1, 2], [3, 4]].map { _1 + _2 }  #=> [3, 7]
+
+  You can still define a local variable named +_1+ and so on,
+  and that is honored when present, but renders a warning.
+
+    _1 = 0            #=> warning: `_1' is reserved for numbered parameter; consider another name
+    [1].each { p _1 } # prints 0 instead of 1
+
+==== proc/lambda without block is deprecated
+
+* Proc.new and Kernel#proc with no block in a method called with a block will
+  now display a warning.
+
+    def foo
+      proc
+    end
+    foo { puts "Hello" } #=> warning: Capturing the given block using Kernel#proc is deprecated; use `&block` instead
+
+  This warning can be suppressed with {-W:no-deprecated option}[#label-Warning+option].
+
+* Kernel#lambda with no block in a method called with a block raises an exception.
+
+    def bar
+      lambda
+    end
+    bar { puts "Hello" } #=> tried to create Proc object without a block (ArgumentError)
+
+==== Other miscellaneous changes
+
+* A beginless range is experimentally introduced.  It might be useful
+  in +case+, new call-sequence of the <code>Comparable#clamp</code>,
+  constants and DSLs.  [Feature #14799]
+
+     ary[..3]  # identical to ary[0..3]
+
+     case RUBY_VERSION
+     when ..."2.4" then puts "EOL"
+     # ...
+     end
+
+     age.clamp(..100)
+
+     where(sales: ..100)
+
+* Setting <code>$;</code> to a non-nil value will now display a warning. [Feature #14240]
+  This includes the usage in String#split.
+  This warning can be suppressed with {-W:no-deprecated option}[#label-Warning+option].
+
+* Setting <code>$,</code> to a non-nil value will now display a warning. [Feature #14240]
+  This includes the usage in Array#join.
+  This warning can be suppressed with {-W:no-deprecated option}[#label-Warning+option].
+
+* Quoted here-document identifiers must end within the same line.
+
+     <<"EOS
+     " # This had been warned since 2.4; Now it raises a SyntaxError
+     EOS
+
+* The flip-flop syntax deprecation is reverted. [Feature #5400]
+
+* Comment lines can be placed between fluent dot now.
+
+    foo
+      # .bar
+      .baz # => foo.baz
+
+* Calling a private method with a literal +self+ as the receiver
+  is now allowed. [Feature #11297] [Feature #16123]
+
+* Modifier rescue now operates the same for multiple assignment as single
+  assignment. [Bug #8279]
+
+    a, b = raise rescue [1, 2]
+    # Previously parsed as: (a, b = raise) rescue [1, 2]
+    # Now parsed as:         a, b = (raise rescue [1, 2])
+
+* +yield+ in singleton class syntax will now display a warning. This behavior
+  will soon be deprecated. [Feature #15575].
+
+   def foo
+     class << Object.new
+       yield #=> warning: `yield' in class syntax will not be supported from Ruby 3.0. [Feature #15575]
+     end
+   end
+   foo { p :ok }
+
+  This warning can be suppressed with {-W:no-deprecated option}[#label-Warning+option].
+
+* Argument forwarding by <code>(...)</code> is introduced. [Feature #16253]
+
+    def foo(...)
+      bar(...)
+    end
+
+  All arguments to +foo+ are forwarded to +bar+, including keyword and
+  block arguments.
+  Note that the parentheses are mandatory.  <code>bar ...</code> is parsed
+  as an endless range.
+
+* Access and setting of <code>$SAFE</code> will now always display a warning.
+  <code>$SAFE</code> will become a normal global variable in Ruby 3.0.  [Feature #16131]
+
+* <code>Object#{taint,untaint,trust,untrust}</code> and related functions in the C-API
+  no longer have an effect (all objects are always considered untainted), and will now
+  display a warning in verbose mode. This warning will be disabled even in non-verbose mode in
+  Ruby 3.0, and the methods and C functions will be removed in Ruby 3.2. [Feature #16131]
+
+* Refinements take place at Object#method and Module#instance_method. [Feature #15373]
+
+=== Command line options
+
+==== Warning option
+
+The +-W+ option has been extended with a following +:+, to manage categorized
+warnings.  [Feature #16345] [Feature #16420]
+
+* To suppress deprecation warnings:
+
+    $ ruby -e '$; = ""'
+    -e:1: warning: `$;' is deprecated
+
+    $ ruby -W:no-deprecated -e '$; = //'
+
+* It works with the +RUBYOPT+ environment variable:
+
+    $ RUBYOPT=-W:no-deprecated ruby -e '$; = //'
+
+* To suppress experimental feature warnings:
+
+    $ ruby -e '0 in a'
+    -e:1: warning: Pattern matching is experimental, and the behavior may change in future versions of Ruby!
+
+    $ ruby -W:no-experimental -e '0 in a'
+
+* To suppress both by using +RUBYOPT+, set space separated values:
+
+    $ RUBYOPT='-W:no-deprecated -W:no-experimental' ruby -e '($; = "") in a'
+
+See also Warning in {Core classes updates}[#label-Core+classes+updates+-28outstanding+ones+only-29].
+
+=== Core classes updates (outstanding ones only)
+
+[Array]
+
+  [New methods]
+
+    * Added Array#intersection. [Feature #16155]
+
+    * Added Array#minmax, with a faster implementation than Enumerable#minmax. [Bug #15929]
+
+[Comparable]
+
+  [Modified method]
+
+    * Comparable#clamp now accepts a Range argument. [Feature #14784]
+
+        -1.clamp(0..2) #=> 0
+         1.clamp(0..2) #=> 1
+         3.clamp(0..2) #=> 2
+        # With beginless and endless ranges:
+        -1.clamp(0..)  #=> 0
+         3.clamp(..2)  #=> 2
+
+
+[Complex]
+
+  [New method]
+
+    * Added Complex#<=>.
+      So <code>0 <=> 0i</code> will not raise NoMethodError. [Bug #15857]
+
+[Dir]
+
+  [Modified methods]
+
+    * Dir.glob and Dir.[] no longer allow NUL-separated glob pattern.
+      Use Array instead.  [Feature #14643]
+
+[Encoding]
+
+  [New encoding]
+
+    * Added new encoding CESU-8. [Feature #15931]
+
+[Enumerable]
+
+  [New methods]
+
+    * Added Enumerable#filter_map.  [Feature #15323]
+
+        [1, 2, 3].filter_map {|x| x.odd? ? x.to_s : nil } #=> ["1", "3"]
+
+    * Added Enumerable#tally.  [Feature #11076]
+
+        ["A", "B", "C", "B", "A"].tally #=> {"A"=>2, "B"=>2, "C"=>1}
+
+[Enumerator]
+
+  [New methods]
+
+    * Added Enumerator.produce to generate an Enumerator from any custom
+      data transformation.  [Feature #14781]
+
+        require "date"
+        dates = Enumerator.produce(Date.today, &:succ) #=> infinite sequence of dates
+        dates.detect(&:tuesday?) #=> next Tuesday
+
+    * Added Enumerator::Lazy#eager that generates a non-lazy enumerator
+      from a lazy enumerator.  [Feature #15901]
+
+        a = %w(foo bar baz)
+        e = a.lazy.map {|x| x.upcase }.map {|x| x + "!" }.eager
+        p e.class               #=> Enumerator
+        p e.map {|x| x + "?" }  #=> ["FOO!?", "BAR!?", "BAZ!?"]
+
+    * Added Enumerator::Yielder#to_proc so that a Yielder object
+      can be directly passed to another method as a block
+      argument.  [Feature #15618]
+
+[Fiber]
+
+  [New method]
+
+    * Added Fiber#raise that behaves like Fiber#resume but raises an
+      exception on the resumed fiber.  [Feature #10344]
+
+[File]
+
+  [Modified method]
+
+    * File.extname now returns a dot string for names ending with a dot on
+      non-Windows platforms.  [Bug #15267]
+
+          File.extname("foo.") #=> "."
+
+[FrozenError]
+
+  [New method]
+
+    * Added FrozenError#receiver to return the frozen object on which
+      modification was attempted.  To set this object when raising
+      FrozenError in Ruby code, FrozenError.new accepts a +:receiver+
+      option.  [Feature #15751]
+
+[GC]
+
+  [New method]
+
+    * Added GC.compact method for compacting the heap.
+      This function compacts live objects in the heap so that fewer pages may
+      be used, and the heap may be more CoW (copy-on-write) friendly. [Feature #15626]
+
+      Details on the algorithm and caveats can be found here:
+      https://bugs.ruby-lang.org/issues/15626
+
+[IO]
+
+  [New method]
+
+    * Added IO#set_encoding_by_bom to check the BOM and set the external
+      encoding.  [Bug #15210]
+
+[Integer]
+
+  [Modified method]
+
+    * Integer#[] now supports range operations.  [Feature #8842]
+
+         0b01001101[2, 4]  #=> 0b0011
+         0b01001100[2..5]  #=> 0b0011
+         0b01001100[2...6] #=> 0b0011
+         #   ^^^^
+
+[Method]
+
+  [Modified method]
+
+    * Method#inspect shows more information. [Feature #14145]
+
+[Module]
+
+  [New methods]
+
+    * Added Module#const_source_location to retrieve the location where a
+      constant is defined.  [Feature #10771]
+
+    * Added Module#ruby2_keywords for marking a method as passing keyword
+      arguments through a regular argument splat, useful when delegating
+      all arguments to another method in a way that can be backwards
+      compatible with older Ruby versions.  [Bug #16154]
+
+  [Modified methods]
+
+    * Module#autoload? now takes an +inherit+ optional argument, like
+      Module#const_defined?.  [Feature #15777]
+
+    * Module#name now always returns a frozen String. The returned String is
+      always the same for a given Module. This change is
+      experimental. [Feature #16150]
+
+[NilClass / TrueClass / FalseClass]
+
+  [Modified methods]
+
+    * NilClass#to_s, TrueClass#to_s, and FalseClass#to_s now always return a
+      frozen String. The returned String is always the same for each of these
+      values. This change is experimental. [Feature #16150]
+
+[ObjectSpace::WeakMap]
+
+  [Modified method]
+
+    * ObjectSpace::WeakMap#[]= now accepts special objects as either key or
+      values.  [Feature #16035]
+
+[Proc]
+
+  [New method]
+
+    * Added Proc#ruby2_keywords for marking the proc as passing keyword
+      arguments through a regular argument splat, useful when delegating
+      all arguments to another method or proc in a way that can be backwards
+      compatible with older Ruby versions.  [Feature #16404]
+
+[Range]
+
+  [New method]
+
+    * Added Range#minmax, with a faster implementation than Enumerable#minmax.
+      It returns a maximum that now corresponds to Range#max. [Bug #15807]
+
+  [Modified method]
+
+    * Range#=== now uses Range#cover? for String arguments, too (in Ruby 2.6, it was
+      changed from Range#include? for all types except strings). [Bug #15449]
+
+
+[RubyVM]
+
+  [Removed method]
+
+    * +RubyVM.resolve_feature_path+ moved to
+      <code>$LOAD_PATH.resolve_feature_path</code>.  [Feature #15903] [Feature #15230]
+
+[String]
+
+  [Unicode]
+
+    * Update Unicode version and Emoji version from 11.0.0 to
+      12.0.0.  [Feature #15321]
+
+    * Update Unicode version to 12.1.0, adding support for
+      U+32FF SQUARE ERA NAME REIWA.  [Feature #15195]
+
+    * Update Unicode Emoji version to 12.1. [Feature #16272]
+
+[Symbol]
+
+  [New methods]
+
+    * Added Symbol#start_with? and Symbol#end_with? methods.  [Feature #16348]
+
+[Time]
+
+  [New methods]
+
+    * Added Time#ceil method.  [Feature #15772]
+
+    * Added Time#floor method.  [Feature #15653]
+
+  [Modified method]
+
+    * Time#inspect is separated from Time#to_s and it shows
+      the time's sub second.  [Feature #15958]
+
+[UnboundMethod]
+
+  [New method]
+
+    * Added UnboundMethod#bind_call method.  [Feature #15955]
+
+      <code>umethod.bind_call(obj, ...)</code> is semantically equivalent
+      to <code>umethod.bind(obj).call(...)</code>.  This idiom is used in
+      some libraries to call a method that is overridden.  The added
+      method does the same without allocation of an intermediate Method
+      object.
+
+          class Foo
+            def add_1(x)
+              x + 1
+            end
+          end
+          class Bar < Foo
+            def add_1(x) # override
+              x + 2
+            end
+          end
+
+          obj = Bar.new
+          p obj.add_1(1) #=> 3
+          p Foo.instance_method(:add_1).bind(obj).call(1) #=> 2
+          p Foo.instance_method(:add_1).bind_call(obj, 1) #=> 2
+
+[Warning]
+
+  [New methods]
+
+    * Added Warning.[] and Warning.[]= to manage emitting/suppressing
+      some categories of warnings.  [Feature #16345] [Feature #16420]
+
+[$LOAD_PATH]
+
+  [New method]
+
+    * Added <code>$LOAD_PATH.resolve_feature_path</code>.  [Feature #15903] [Feature #15230]
+

+  * Now show "Did you mean?" for unknown options.  [Feature #16256]
+
+    test.rb:
+
+      require "optparse"
+      OptionParser.new do |opts|
+        opts.on("-f", "--foo", "foo") {|v| }
+        opts.on("-b", "--bar", "bar") {|v| }
+        opts.on("-c", "--baz", "baz") {|v| }
+      end.parse!
+
+    example:

+
+[StringScanner]
+
+  * Upgrade to 1.0.3.
+    See https://github.com/ruby/strscan/blob/master/NEWS.md.
+
+=== Compatibility issues (excluding feature bug fixes)
+
+* The following libraries are no longer bundled gems.
+  Install corresponding gems to use these features.
+  * CMath (cmath gem)
+  * Scanf (scanf gem)
+  * Shell (shell gem)
+  * Synchronizer (sync gem)
+  * ThreadsWait (thwait gem)
+  * E2MM (e2mmap gem)
+
+[Proc]
+  * The Proc#to_s format was changed. [Feature #16101]
+
+[Range]
+  * Range#minmax used to iterate on the range to determine the maximum.
+    It now uses the same algorithm as Range#max. In rare cases (e.g.
+    ranges of Floats or Strings), this may yield different results. [Bug #15807]
+
+=== Stdlib compatibility issues (excluding feature bug fixes)
+
+* Promote stdlib to default gems
+  * The following default gems were published on rubygems.org
+    * benchmark
+    * cgi
+    * delegate
+    * getoptlong
+    * net-pop
+    * net-smtp
+    * open3
+    * pstore
+    * readline
+    * readline-ext
+    * singleton
+  * The following default gems were only promoted at ruby-core,
+    but not yet published on rubygems.org.
+    * monitor
+    * observer
+    * timeout
+    * tracer
+    * uri
+    * yaml
+* The <tt>did_you_mean</tt> gem has been promoted up to a default gem from a bundled gem
+
+[pathname]
+
+  * Kernel#Pathname when called with a Pathname argument now returns
+    the argument instead of creating a new Pathname. This is more
+    similar to other Kernel methods, but can break code that modifies
+    the return value and expects the argument not to be modified.
+
+[profile.rb, Profiler__]
+
+  * Removed from standard library. It was unmaintained since Ruby 2.0.0.
+
+=== C API updates
+
+* Many <code>*_kw</code> functions have been added for setting whether
+  the final argument being passed should be treated as keywords. You
+  may need to switch to these functions to avoid keyword argument
+  separation warnings, and to ensure correct behavior in Ruby 3.
+
+* The <code>:</code> character in rb_scan_args format string is now
+  treated as keyword arguments. Passing a positional hash instead of
+  keyword arguments will emit a deprecation warning.
+
+* C API declarations with +ANYARGS+ are changed not to use +ANYARGS+.
+  See https://github.com/ruby/ruby/pull/2404
+
+=== Implementation improvements
+
+[Fiber]
+
+  * Allow selecting different coroutine implementations by using
+    +--with-coroutine=+, e.g.
+
+         $ ./configure --with-coroutine=ucontext
+         $ ./configure --with-coroutine=copy
+
+  * Replace previous stack cache with fiber pool cache. The fiber pool
+    allocates many stacks in a single memory region. Stack allocation
+    becomes O(log N) and fiber creation is amortized O(1). Around 10x
+    performance improvement was measured in micro-benchmarks.
+    https://github.com/ruby/ruby/pull/2224
+
+[File]
+  * File.realpath now uses realpath(3) on many platforms, which can
+    significantly improve performance. [Feature #15797]
+
+[Hash]
+  * Change data structure of small Hash objects. [Feature #15602]
+
+[Monitor]
+  * Monitor class is written in C-extension. [Feature #16255]
+
+[Thread]
+
+  * VM stack memory allocation is now combined with native thread stack,
+    improving thread allocation performance and reducing allocation related
+    failures. Around 10x performance improvement was measured in micro-benchmarks.
+
+[JIT]
+
+  * JIT-ed code is recompiled to less-optimized code when an optimization assumption is invalidated.
+
+  * Method inlining is performed when a method is considered as pure.
+    This optimization is still experimental and many methods are NOT considered as pure yet.
+
+  * The default value of +--jit-max-cache+ is changed from 1,000 to 100.
+
+  * The default value of +--jit-min-calls+ is changed from 5 to 10,000.
+
+[RubyVM]
+
+  * Per-call-site method cache, which has been there since around 1.9, was
+    improved: cache hit rate raised from 89% to 94%.
+    See https://github.com/ruby/ruby/pull/2583
+
+[RubyVM::InstructionSequence]
+
+  * RubyVM::InstructionSequence#to_binary method generates compiled binary.
+    The binary size is reduced. [Feature #16163]
+
+=== Miscellaneous changes
+
+* Support for IA64 architecture has been removed. Hardware for testing was
+  difficult to find, native fiber code is difficult to implement, and it added
+  non-trivial complexity to the interpreter. [Feature #15894]
+
+* Require compilers to support C99. [Misc #15347]
+
+  * Details of our dialect: https://bugs.ruby-lang.org/projects/ruby-master/wiki/C99
+
+* Ruby's upstream repository is changed from Subversion to Git.
+
+  * https://git.ruby-lang.org/ruby.git
+
+  * RUBY_REVISION class is changed from Integer to String.
+
+  * RUBY_DESCRIPTION includes Git revision instead of Subversion's one.
+
+* Support built-in methods in Ruby with the <code>_\_builtin_</code> syntax. [Feature #16254]
+
+  Some methods are defined in *.rb (such as trace_point.rb).
+  For example, it is easy to define a method which accepts keyword arguments.

+= Bug Triaging Guide
+
+This guide discusses recommendations for triaging bugs in Ruby's bug tracker.
+
+== Bugs with Reproducible Examples
+
+These are the best bug reports.  First, consider whether the bug reported is
+actually an issue or if it is expected Ruby behavior.  If it is expected Ruby
+behavior, update the issue with why the behavior is expected, and set the
+status to Rejected.
+
+If the bug reported appears to be an actual bug, try reproducing the bug with
+the master branch.  If you are not able to reproduce the issue on the master
+branch, try reproducing it on the latest version for the branch the bug was
+reported on.  If you cannot reproduce the issue in either case, update
+the issue stating you cannot reproduce the issue, ask the reporter if they
+can reproduce the issue with either the master branch or a later release,
+and set the status to Feedback.
+
+If you can reproduce the example with the master branch, try to figure out
+what is causing the issue.  If you feel comfortable, try working on a
+patch for the issue, update the issue, and attach the patch.  Try to figure
+out which committer should be assigned to the issue, and set them as the
+assignee, and set the status to Assigned.
+
+If you cannot reproduce the example with the master branch, but can reproduce
+the issue on the latest version for the branch, then it is likely the bug has
+already been fixed, but it has not been backported yet.  Try to determine
+which commit fixed it, and update the issue noting that the issue has been
+fixed but not yet backported.  If the Ruby version is in the security
+maintenance phase or no longer supported, change the status to Closed. This
+change can be made without adding a note to avoid spamming the mailing list.
+
+For issues that may require backwards incompatible changes or may benefit from
+general committer attention or discussion, consider adding them as agenda
+items for the next committer meeting (https://bugs.ruby-lang.org/issues/14770).
+
+== Crash Bugs Without Reproducers
+
+Many bugs reported have little more than a crash report, often with no way to
+reproduce the issue.  These bugs are difficult to triage as they often do not
+contain enough information.
+
+For these bugs, if the Ruby version is the master branch or is the latest
+release for the branch and the branch is in normal maintenance phase, look at
+the backtrace and see if you can determine what could be causing the issue.
+If you can guess what could be causing the issue, see if you can put together
+a reproducible example (this is in general quite difficult).  If you cannot
+guess what could be causing the issue, or cannot put together a reproducible
+example yourself, please ask the reporter to provide a reproducible example,
+and change the status to Feedback.
+
+If the Ruby version is no longer current (e.g. 2.5.0 when the latest version
+on the Ruby 2.5 branch is 2.5.5), add a note to the issue asking the reporter
+to try the latest Ruby version for the branch and report back, and change the
+status to Feedback.  If the Ruby version is in the security maintenance phase
+or no longer supported, change the status to Closed. This change can be made
+without adding a note.
+
+== Crash Bugs With 3rd Party C Extensions
+
+If the crash happens inside a 3rd party C extension, try to figure out inside
+which C extension it happens, and add a note to the issue to report the
+issue to that C extension, and set the status to Third Party's Issue.
+
+== Non-Bug reports
+
+Any issues in the bug tracker that are not reports of problems should have
+the tracker changed from Bug to either Feature (new features or performance
+improvements) or Misc. This change can be made without adding a note.
+
+== Stale Issues
+
+There are many issues that are stale, with no updates in months or even years.
+For stale issues in Feedback state, where the feedback has not been received,
+you can change the status to Closed without adding a note.  For stale issues
+in Assigned state, you can reach out to the assignee and see if they can update
+the issue.  If the assignee is no longer an active committer, remove them
+as the assignee and change the status to Open.

+= Contributing to Ruby
+
+Ruby has a vast and friendly community with hundreds of people contributing to
+a thriving open-source ecosystem. This guide is designed to cover ways for
+participating in the development of CRuby.
+
+There are plenty of ways for you to help even if you're not ready to write
+code or documentation.  You can help by reporting issues, testing patches, and
+trying out beta releases with your applications.
+
+== How To Report
+
+If you've encountered a bug in Ruby please report it to the redmine issue
+tracker available at {bugs.ruby-lang.org}[https://bugs.ruby-lang.org/].  Do not
+report security vulnerabilities here, there is a {separate
+channel}[rdoc-label:label-Reporting+Security+Issues] for them.
+
+There are a few simple steps you should follow in order to receive feedback
+on your ticket.
+
+* If you haven't already,
+  {sign up for an account}[https://bugs.ruby-lang.org/account/register] on the
+  bug tracker.
+* Try the latest version.
+
+  If you aren't already using the latest version, try installing a newer
+  stable release. See
+  {Downloading Ruby}[https://www.ruby-lang.org/en/downloads/].
+* Look to see if anyone already reported your issue, try
+  {searching on redmine}[https://bugs.ruby-lang.org/projects/ruby-master/issues]
+  for your problem.
+* If you can't find a ticket addressing your issue,
+  {create a new one}[https://bugs.ruby-lang.org/projects/ruby-master/issues/new].
+* Choose the target version, usually current. Bugs will be first fixed in the
+  current release and then {backported}[rdoc-label:label-Backport+Requests].
+* Fill in the Ruby version you're using when experiencing this issue
+  (<code>ruby -v</code>).
+* Attach any logs or reproducible programs to provide additional information.
+  Reproducible scripts should be as small as possible.
+* Briefly describe your problem.  A 2-3 sentence description will help give a
+  quick response.
+* Pick a category, such as core for common problems, or lib for a standard
+  library.
+* Check the {Maintainers
+  list}[https://bugs.ruby-lang.org/projects/ruby/wiki/Maintainers] and assign
+  the ticket if there is an active maintainer for the library or feature.
+* If the ticket doesn't have any replies after 10 days, you can send a
+  reminder.
+* Please reply to feedback requests. If a bug report doesn't get any feedback,
+  it'll eventually get rejected.
+
+=== Reporting to downstream distributions
+
+You can report downstream issues for the following distributions via their bug tracker:
+
+* {debian}[https://bugs.debian.org/cgi-bin/pkgreport.cgi?src=ruby-defaults]
+* {freebsd}[http://www.freebsd.org/cgi/query-pr-summary.cgi?text=ruby]
+* {redhat}[https://bugzilla.redhat.com/buglist.cgi?bug_status=NEW&bug_status=ASSIGNED&bug_status=REOPENED&bug_status=MODIFIED]
+* {macports}[https://trac.macports.org/query?status=assigned&status=new&status=reopened&port=~ruby]
+* etc (add your distribution bug tracker here)
+
+=== Platform Maintainers
+
+For platform specific bugs in Ruby, you can assign your ticket to the current
+maintainer for a specific platform.
+
+The current active platform maintainers are as follows:
+
+[mswin64 (Microsoft Windows)]
+  NAKAMURA Usaku (usa)
+[mingw32 (Minimalist GNU for Windows)]
+  Nobuyoshi Nakada (nobu)
+[AIX]
+  Yutaka Kanemoto (kanemoto)
+[FreeBSD]
+  Akinori MUSHA (knu)
+[Solaris]
+  Naohisa Goto (ngoto)
+[RHEL, CentOS]
+  KOSAKI Motohiro (kosaki)
+[macOS]
+  Kenta Murata (mrkn)
+[OpenBSD]
+  Jeremy Evans (jeremyevans0)
+[cygwin, ...]
+  none. (Maintainer WANTED)
+
+== Reporting Security Issues
+
+Security vulnerabilities receive special treatment since they may negatively
+affect many users. There is a private mailing list that all security issues
+should be reported to and will be handled discretely. Email the
+mailto:security@ruby-lang.org list and the problem will be published after
+fixes have been released. You can also encrypt the issue using {the PGP public
+key}[https://www.ruby-lang.org/security.asc] for the list.
+
+== Reporting Other Issues
+
+If you're having an issue with the website, or maybe the mailing list, you can
+contact the webmaster to help resolve the problem.
+
+The current webmaster is:
+
+* Hiroshi SHIBATA (hsbt)
+
+You can also report issues with the ruby-lang.org website on the issue tracker:
+
+* {issue tracker}[https://github.com/ruby/www.ruby-lang.org/issues]
+
+== Resolve Existing Issues
+
+As a next step beyond reporting issues you can help the core team resolve
+existing issues. If you check the Everyone's Issues list in GitHub Issues,
+you will find a lot of issues already requiring attention. What can you do for
+these? Quite a bit, actually:
+
+When a bug report goes for a while without any feedback, it goes to the bug
+graveyard which is unfortunate. If you check the {issues
+list}[https://bugs.ruby-lang.org/projects/ruby-master/issues] you will find lots
+of delinquent bugs that require attention.
+
+You can help by verifying the existing tickets, try to reproduce the reported
+issue on your own and comment if you still experience the bug. Some issues
+lack attention because of too much ambiguity, to help you can narrow down the
+problem and provide more specific details or instructions to reproduce the
+bug. You might also try contributing a failing test in the form of a patch,
+which we will cover later in this guide.
+
+It may also help to try out patches other contributors have submitted to
+redmine, if gone without notice. In this case the +patch+ command is your
+friend, see <code>man patch</code> for more information. Basically this would
+go something like this:
+
+  cd path/to/ruby
+  patch -p0 < path/to/patch
+
+You will then be prompted to apply the patch with the associated files. After
+building ruby again, you should try to run the tests and verify if the change
+actually worked or fixed the bug. It's important to provide valuable feedback
+on the patch that can help reach the overall goal, try to answer some of these
+questions:
+
+* What do you like about this change?
+* What would you do differently?
+* Are there any other edge cases not tested?
+* Is there any documentation that would be affected by this change?
+
+If you can answer some or all of these questions, you're on the right track.
+If your comment simply says "+1", then odds are that other reviewers aren't
+going to take it too seriously. Show that you took the time to review the
+patch.
+
+== How To Request Features
+
+If there's a new feature that you want to see added to Ruby, you will need to
+write a convincing proposal and patch to implement the feature.
+
+For new features in CRuby, use the {'Feature'
+tracker}[https://bugs.ruby-lang.org/projects/ruby-master/issues?set_filter=1&tracker_id=2]
+on ruby-master. For non-CRuby dependent features, features that would apply to
+alternate Ruby implementations such as JRuby and Rubinius, use the {CommonRuby
+tracker}[https://bugs.ruby-lang.org/projects/common-ruby].
+
+When writing a proposal be sure to check for previous discussions on the
+topic and have a solid use case. You will need to be persuasive and convince
+Matz on your new feature. You should also consider the potential compatibility
+issues that this new feature might raise.
+
+Consider making your feature into a gem, and if there are enough people who
+benefit from your feature it could help persuade ruby-core. Although feature
+requests can seem like an alluring way to contribute to Ruby, often these
+discussions can lead nowhere and exhaust time and energy that could be better
+spent fixing bugs. Choose your battles.
+
+A good template for a feature proposal should look something like this:
+
+[Abstract]
+  Summary of your feature
+[Background]
+  Describe current behavior and why it is problem. Related work, such as
+  solutions in other language helps us to understand the problem.
+[Proposal]
+  Describe your proposal in details
+[Details]
+  If it has complicated feature, describe it
+[Usecase]
+  How would your feature be used? Who will benefit from it?
+[Discussion]
+  Discuss about this proposal. A list of pros and cons will help start
+  discussion.
+[Limitation]
+  Limitation of your proposal
+[Another alternative proposal]
+  If there are alternative proposals, show them.
+[See also]
+  Links to the other related resources
+
+== Backport Requests
+
+When a new version of Ruby is released, it starts at patch level 0 (p0), and
+bugs will be fixed first on the master branch. If it's determined that a bug
+exists in a previous version of Ruby that is still in the bug fix stage of
+maintenance, then a patch will be backported. After the maintenance stage of a
+particular Ruby version ends, it goes into "security fix only" mode which
+means only security related vulnerabilities will be backported. Versions in
+End-of-life (EOL) will not receive any updates and it is recommended you
+upgrade as soon as possible.
+
+If a major security issue is found or after a certain amount of time since the
+last patch level release, a new patch-level release will be made.
+
+When submitting a backport request please confirm the bug has been fixed in
+newer versions and exists in maintenance mode versions. There is a backport
+tracker for each major version still in maintenance where you can request a
+particular revision merged in the affected version of Ruby.
+
+Each major version of Ruby has a release manager that should be assigned to
+handle backport requests. You can find the list of release managers on the
+{wiki}[https://bugs.ruby-lang.org/projects/ruby/wiki/ReleaseEngineering].
+
+=== Branches
+
+Status and maintainers of branches are listed on the
+{wiki}[https://bugs.ruby-lang.org/projects/ruby/wiki/ReleaseEngineering].
+
+== Running tests
+
+In order to help resolve existing issues and contributing patches to Ruby you
+need to be able to run the test suite.
+
+CRuby uses git for source control, the {git homepage}[https://git-scm.com/]
+has installation instructions with links to documentation for learning more
+about git. There is a mirror of the repository on {github}[https://github.com/ruby/ruby].
+For other resources see the {ruby-core documentation on
+ruby-lang.org}[https://www.ruby-lang.org/en/community/ruby-core/].
+
+Install the prerequisite dependencies for building the CRuby interpreter to
+run tests.
+
+* C compiler
+* autoconf - 2.67 or later, preferably 2.69.
+* bison - 2.0 or later, preferably 3.4.
+* gperf - 3.0.3 or later, preferably 3.1.
+* ruby - Ruby itself is prerequisite in order to build Ruby from source.
+  You should use [a maintained version of Ruby](https://www.ruby-lang.org/en/downloads/).
+
+You should also have access to development headers for the following
+libraries, but these are not required:
+
+* NDBM/QDBM
+* GDBM
+* OpenSSL/LibreSSL
+* readline/editline(libedit)
+* zlib
+* libffi
+* libyaml
+* libexecinfo (FreeBSD)
+
+Now let's build CRuby:
+
+* Checkout the CRuby source code:
+
+    git clone https://github.com/ruby/ruby.git ruby-master
+
+* Generate the configuration files and build:
+
+    cd ruby-master
+    autoconf
+    mkdir build && cd build # its good practice to build outside of source dir
+    mkdir ~/.rubies # we will install to .rubies/ruby-master in our home dir
+    ../configure --prefix="${HOME}/.rubies/ruby-master"
+    make up && make install
+
+After adding Ruby to your PATH, you should be ready to run the test suite:
+
+    make test
+
+You can also use +test-all+ to run all of the tests with the RUNRUBY
+interpreter just built. Use TESTS or RUNRUBYOPT to pass parameters, such as:
+
+    make test-all TESTS=-v
+
+This is also how you can run a specific test from our build dir:
+
+    make test-all TESTS=drb/test_drb.rb
+
+You can run +test+ and +test-all+ at once by +check+ .
+
+    make check
+
+For older versions of Ruby you will need to run the build setup again after
+checking out the associated branch in git, for example if you wanted to
+checkout 1.9.3:
+
+    git clone https://github.com/ruby/ruby.git --branch ruby_1_9_3
+
+Once you checked out the source code, you can update the local copy by:
+
+    make up
+
+Or, update, build, install and check, by just:
+
+    make love
+
+== Contributing Documentation
+
+If you're interested in contributing documentation directly to CRuby there is
+some information available at
+{Contributing}[https://github.com/ruby/ruby#contributing].
+
+There is also the {Ruby Reference
+Manual}[https://github.com/rurema/doctree/wiki] in Japanese.
+
+== Contributing A Patch
+
+=== Deciding what to patch
+
+Before you submit a patch, there are a few things you should know:
+
+* Pay attention to the maintenance policy for stable and maintained versions of Ruby.
+* Released versions in security mode will not merge feature changes.
+* Search for previous discussions on ruby-core to verify the maintenance policy
+* Patches must be distributed under Ruby's license.
+* This license may change in the future, you must join the discussion if you don't agree to the change
+
+To improve the chance your patch will be accepted please follow these simple rules:
+
+* Bug fixes should be committed on master first
+* Format of the patch file must be a unified diff (ie: diff -pu, svn diff, or git diff)
+* Don't introduce cosmetic changes
+* Follow the original coding style of the code
+* Don't mix different changes in one commit
+
+First thing you should do is check out the code if you haven't already:
+
+  git clone https://github.com/ruby/ruby.git ruby-master
+
+Now create a dedicated branch:
+
+  cd ruby-master
+  git checkout -b my_new_branch
+
+The name of your branch doesn't really matter because it will only exist on
+your local computer and won't be part of the official Ruby repository. It will
+be used to create patches based on the differences between your branch and
+master, or edge Ruby.
+
+=== Coding style
+
+Here are some general rules to follow when writing Ruby and C code for CRuby:
+
+* Indent 4 spaces for C without tabs (old codes might use tabs for eight-space indentation,
+  but newer codes recommend to use spaces only)
+* Indent 2 space tabs for Ruby
+* Do not use TABs in ruby codes
+* ANSI C style for 1.9+ for function declarations
+* Follow C90 (not C99) Standard
+* PascalStyle for class/module names.
+* UNDERSCORE_SEPARATED_UPPER_CASE for other constants.
+* Capitalize words.
+* ABBRs should be all upper case.
+* Do as others do
+
+=== Commit messages
+
+When you're ready to commit:
+
+   git commit path/to/files
+
+This will open your editor in which you write your commit message.
+Use the following style for commit messages:
+
+* Use a succinct subject line.
+* Include reasoning behind the change in the commit message, focusing on why
+  the change is being made.
+* Refer to redmine issue (such as Fixes [Bug #1234] or Implements
+  [Feature #3456]), or discussion on the mailing list
+  (such as [ruby-core:12345]).
+* For GitHub issues, use [GH-#] (such as [Fixes GH-234]).
+* Follow the style used by other committers.
+
+=== Contributing your code
+
+Now that you've got some code you want to contribute, let's get set up to
+generate a patch. Start by forking the github mirror, check the {github docs on
+forking}[https://help.github.com/articles/fork-a-repo] if you get stuck here.
+You will only need a github account if you intend to host your repository
+on github.
+
+Next copy the writable url for your fork and add it as a git remote, replace
+"my_username" with your github account name:
+
+    git remote add my_fork git@github.com:my_username/ruby.git
+    # Now we can push our branch to our fork
+    git push my_fork my_new_branch
+
+In order to generate a patch that you can upload to the bug tracker, we can use
+the github interface to review our changes just visit
+https://github.com/my_username/ruby/compare/master...my_new_branch
+
+Next, you can simply add '.patch' to the end of this URL and it will generate
+the patch for you, save the file to your computer and upload it to the bug
+tracker. Alternatively you can submit a pull request, but for the best chances
+to receive feedback add it is recommended you add it to redmine.
+
+Since git is a distributed system, you are welcome to host your git repository
+on any {publicly accessible hosting
+site}[https://git.wiki.kernel.org/index.php/GitHosting], including {hosting your
+own}[https://www.kernel.org/pub/software/scm/git/docs/user-manual.html#public-repositories]
+You may use the {'git format-patch'}[https://git-scm.com/docs/git-format-patch]
+command to generate patch files to upload to redmine.  You may also use
+the {'git request-pull'}[https://git-scm.com/docs/git-request-pull] command for
+formatting pull request messages to redmine.
+
+=== Updating the official repository
+
+If you are a committer, you can push changes directly into the official
+repository:
+
+    git push origin your-branch-name:master
+
+However, it is likely will have become outdated, and you will have to
+update it.  In that case, run:
+
+    git fetch origin
+    git rebase remotes/origin/master
+
+and then try pushing your changes again.
