+* Hash literal
+  * Symbol key followed by a colon can be quoted. [Feature #4276]
+
+* default argument
+  fixed a very longstanding bug that an optional argument was not
+  accessible in its default value expression.  [Bug #9593]
+
+=== Core classes updates (outstanding ones only)
+

+  * Extended methods:
+    * min, min_by, max and max_by supports optional argument to return
+      multiple elements.
+
+* Float
+  * New methods:
+    * Float#next_float

+    * Kernel#itself
+  * Improvements
+    * Kernel#throw raises UncaughtThrowError, subclass of ArgumentError when
+      there is no corresponding catch block, instead of ArgumentError.
+
+* Process
+  * Extended method:
+    * Process execution methods such as Process.spawn opens the file in write
+      mode for redirect from [:out, :err].
+
+* String
+  * New methods:
+    * String#unicode_normalize
+    * String#unicode_normalize!
+    * String#unicode_normalized?

+
+=== Core classes compatibility issues (excluding feature bug fixes)
+
+* Enumerable
+  * Enumerable#slice_before's state management deprecated.
+  * Enumerable#chunk's state management deprecated.
+
+* GC
+  * incompatible changes:

+      See https://docs.google.com/spreadsheets/d/11Ua4uBr6o0k-nORrZLEIIUkHJ9JRzRR0NyZfrhEEnc8/edit?usp=sharing
+
+* 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
+  * Process execution methods such as Process.spawn opens the file in write
+    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+  * callcc is obsolete.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.
+
+* DL
+  * DL has been removed from stdlib. Please use Fiddle instead!
+
+* Etc
+  * New methods:
+    * Etc.uname
+    * Etc.sysconf
+    * Etc.confstr
+    * IO#pathconf
+    * Etc.nprocessors
+
+* Find, Pathname
+  * Extended methods:
+    * find method accepts "ignore_error" keyword argument.
+
+* 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).
+    * 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
+
+* Rake

+    no block given.
+
+* XMLRPC

+
+=== Stdlib compatibility issues (excluding feature bug fixes)
+
+* lib/mathn.rb
+  * Show deprecated warning [Feature #10169]
+
+* ext/date/lib/date/format.rb
+  * Removed because it's empty file.

+
+* time.rb
+  * Time.parse, Time.strptime, Time.rfc2822, Time.xmlschema may produce
+    fixed-offset Time objects.
+    It is happen when usual localtime doesn't preserve the offset from UTC.
+  * Time.httpdate produces always UTC Time object.
+  * Time.strptime raises ArgumentError when no date information.
+
+* lib/rational.rb
+  * Removed because it is deprecated from 2009.
+
+* lib/complex.rb
+  * Removed because it is deprecated from 2009.
+
+* lib/prettyprint.rb

+  * ObjectSpace.memsize_of(obj) returns a size includes sizeof(RVALUE).
+    [Bug #8984]
+
+* Prime
+  * incompatible changes:
+    * Prime.prime? now returns false for negative numbers. This method
+      should not be used to know the number is composite or not. [Bug #7395]
+
+* Psych
+  * Removed Psych::EngineManager [Bug #8344]
+
+=== 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.
+  rb_io_mode_flags -> rb_io_modestr_fmode
+  rb_io_modenum_flags -> rb_io_oflags_fmode
+
+* 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.
