-	* array.c (ARY_SET): added.

-	  ARY_SET() is same functionality of RARRAY_ASET(), but
-	  it has an assertion (`ary' doesn't have shared array).
-
-Fri Apr 11 16:54:26 2014  Koichi Sasada  <ko1@atdot.net>
-
-	* array.c: make shared arrays WB-protected objects.
-
-	  Shared arrays were WB-unprotected object because
-	  sharing array can modify shared array's buffer
-	  if it occupied shared array.

-	             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)
-
-	  This patch insert WB() for `shared' if it is needed.

-	  array owner is promoted and a shared array is not promoted.
-
-	  Now, shared array is WB-unprotected so that shared arrays are not
-	  promoted.  All objects referred from shared array should be marked

-	* configure.in: Fix a build problem with clang and --with-opt-dir.
-	  If ruby is configured with --with-opt-dir=dir when using clang
-	  as compiler, a warning `clang: warning: argument unused during
-	  compilation: '-I dir'` is emitted almost every time clang
-	  compiles a file.  Unfortunately, RUBY_CHECK_PRINTF_PREFIX takes
-	  any output from the compiler as fatal error, and the check thus
-	  fails due to the warning.  This is an attempt to fix the problem
-	  by adding a flag -Qunused-arguments to CFLAGS locally in the
-	  function to suppress the warning. [ruby-dev:48062] [Bug #9658]

-	  is, dladdr may fail to detect the main function but detect
-	  as _start function. Therefore it must be after scanning

-= NEWS for Ruby 2.2.0
-
-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.
-
-== Changes since the 2.1.0 release
-
-=== Language changes
-
-=== Core classes updates (outstanding ones only)
-
-* Enumerable
-  * Extended methods:
-    * min, min_by, max and max_by supports optional argument to return
-      multiple elements.
-
-* Symbol
-  * New methods
-    * Symbol.find(str) returns whether given string is defined as symbol or not.
-  * Improvements
-    * Most symbols which are returned by String#to_sym and
-      String#intern are GC-able.
-
-* Matrix
-  * New methods:
-    * Matrix#first_minor(row, column) returns the submatrix obtained
-      by deleting the specified row and column.
-    * Matrix#cofactor(row, column) returns the (row, column) cofactor
-      which is obtained by multiplying the first minor by (-1)**(row + column).
-
-=== Core classes compatibility issues (excluding feature bug fixes)
-
-* IO
-  * incompatible changes:
-    * When flushing file IO, 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.
-* 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.
-
-=== Stdlib updates (outstanding ones only)
-
-* Find, Pathname
-  * Extended methods:
-    * find method accepts "ignore_error" keyword argument.
-
-=== Stdlib compatibility issues (excluding feature bug fixes)
-
-=== Built-in global variables compatibility issues
-
-=== C API updates
-
-* Deprecated APIs removed.  [Feature #9502]
-
-  Check_SafeStr -> SafeStringValue
-  rb_check_safe_str -> SafeStringValue
-  rb_quad_pack -> rb_integer_pack
-  rb_quad_unpack -> rb_integer_unpack
-  rb_read_check : access struct FILE internal. no replacement.
-  rb_struct_iv_get : internal function. no replacement.
-  struct rb_blocking_region_buffer : internal type. no replacement.
-  rb_thread_blocking_region_begin -> rb_thread_call_without_gvl family
-  rb_thread_blocking_region_end -> rb_thread_call_without_gvl family
-  TRAP_BEG -> rb_thread_call_without_gvl family
-  TRAP_END -> rb_thread_call_without_gvl family
-  rb_thread_select -> rb_thread_fd_select
-  struct rb_exec_arg : internal type. no replacement.
-  rb_exec : internal function. no replacement.
-  rb_exec_arg_addopt : internal function. no replacement.
-  rb_exec_arg_fixup : internal function. no replacement.
-  rb_exec_arg_init : internal function. no replacement.
-  rb_exec_err : internal function. no replacement.
-  rb_fork : internal function. no replacement.
-  rb_fork_err : internal function. no replacement.
-  rb_proc_exec_n : internal function. no replacement.
-  rb_run_exec_options : internal function. no replacement.
-  rb_run_exec_options_err : internal function. no replacement.
-  rb_thread_blocking_region -> rb_thread_call_without_gvl family
-  rb_thread_polling -> rb_thread_wait_for
-  rb_big2str0 : internal function. no replacement.
-  rb_big2ulong_pack -> rb_integer_pack
-  rb_gc_set_params : internal function. no replacement.
-
-* struct RBignum is hidden.  [Feature #6083]
-  Use rb_integer_pack and rb_integer_unpack instead.
-
-* 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.
-
-* struct RSymbol added. This represents a dynamic symbol as object in
-  Ruby's heaps.
