== Changes since the 1.8.6 release

=== Library updates (outstanding ones only)

* new library

  * securerandom

* builtin classes

  * Integer#ord implemented.

  * Regexp.union accepts an array of patterns.

* ipaddr

  * New methods
    * IPAddr#<=>
    * IPAddr#succ

      IPAddr objects are now comparable and enumerable having these
      methods.  This also means that it is possible to have a Range
      object between two IPAddr objects.

    * IPAddr#to_range

      A new method to create a Range object for the (network) address.

  * Type coercion support
    * IPAddr#&
    * IPAddr#|
    * IPAddr#==
    * IPAddr#include?

      These methods now accept a string or an integer instead of an
      IPAddr object as the argument.

* openssl

  * New classes
    * OpenSSL::PKey::EC
    * OpenSSL::PKey::EC::Group
    * OpenSSL::PKey::EC::Point
    * OpenSSL::PKey::PKCS5
    * OpenSSL::SSL::Session

  * Documentation!

  * Various new methods (see documentation).

  * Remove redundant module namespace in Cipher, Digest, PKCS7, PKCS12.
    Compatibility classes are provided which will be removed in Ruby 1.9.

* shellwords

  * Add methods for escaping shell-unsafe characters:
    * Shellwords.join
    * Shellwords.escape
    * Array#shelljoin
    * String#shellescape

  * Add shorthand methods:
    * Shellwords.split (alias shellwords)
    * String#shellsplit

* tempfile

  * Tempfile.open and Tempfile.new now accept a suffix for the
    temporary file to be created.  To specify a suffix, pass an array
    of [basename, suffix] as the first argument.

      Tempfile.open(['image', 'jpg']) { |tempfile| ... }

* rss

  * 0.1.6 -> 0.2.1

  * Fix image module URI

  * Atom support

  * ITunes module support

  * Slash module support

  * content:encoded with RSS 2.0 support

=== Compatibility issues (excluding feature bug fixes)

* 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.

* tmpdir

  * New method:
    * Dir.mktmpdir


== Changes since the 1.8.5 release

=== New platforms/build tools support

* IA64 HP-UX

* Visual C++ 8 SP1

* autoconf 2.6x

=== 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")

* 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.
