-
-==== 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 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 a keyword argument keys if 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)    # {}
-
-==== Numbered parameter
-
-* Numbered parameter as the default block parameter is introduced as an
-  experimental feature.  [Feature #4475]
-
-    [1, 2, 10].map { _1.to_s(16) } #=> ["1", "2", "a"]
-
-  You can still define a local variable named _1 and so on, and that is honored when present, but renders 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 is
-  warned now.
-
-    def foo
-      proc
-    end
-    foo { puts "Hello" } #=> warning: Capturing the given block using Kernel#proc is deprecated; use `&block` instead
-
-* 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 not be as useful
-  as an endless range, but would be good for DSL purpose.  [Feature #14799]
-
-     ary[..3]  # identical to ary[0..3]
-     where(sales: ..100)
-
-* Setting <code>$;</code> to non-nil value is warned now.  Use of it in
-  String#split is warned too.
-
-* Setting <code>$,</code> to non-nil value is warned now.  Use of it in
-  Array#join is warned too.
-
-* Quoted here-document identifier 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 <code>self</code> as the receiver
-  is now allowed. [Feature #11297] [Feature #16123]
-
-* Modifier rescue now operates the same for multiple assignment as single
-  assignment:
-
-    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 is warned and will be deprecated later [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 }
-
-* 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.  `bar ...` is parsed as an endless range.
-
-* Access and setting of <code>$SAFE</code> is now always warned. <code>$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 are now
-  warned 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]
-

-        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!?"]
-

-FrozenError::
-
-  New method::
-
-    * Added FrozenError#receiver to return the frozen object that

-      FrozenError in Ruby code, pass it as the second argument to
-      FrozenError.new. [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 friendly. [Feature #15626]
-
-      Details on the algorithm and caveats can be found here:
-      https://bugs.ruby-lang.org/issues/15626
-

-  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 as
-      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.
-      [Bug #15807]
-
-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]

-      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 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
-
-
-$LOAD_PATH::
-
-  New method::
-
-    * Added <code>$LOAD_PATH.resolve_feature_path</code>.  [Feature #15903] [Feature #15230]
-

-  * Object#DelegateClass accepts a block and module_evals it in the context
-    of the returned class, similar to Class.new and Struct.new.
-
-ERB::
-
-  * Prohibit marshaling ERB instance.
-
-IRB::
-

-
-OptionParser::
-
-  * Now show "Did you mean?" for unknown option.  [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:
-
-      $ ruby test.rb --baa
-      Traceback (most recent call last):
-      test.rb:7:in `<main>': invalid option: --baa (OptionParser::InvalidOption)
-      Did you mean?  baz
-                     bar
-

-
-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::
-  * Proc#to_s format was changed. [Feature #16101]
-
-=== Stdlib compatibility issues (excluding feature bug fixes)
-
-* Promote stdlib to default gems
-  * The following default gems was published at rubygems.org
-    * benchmark
-    * cgi
-    * delegate
-    * getoptlong
-    * net-pop
-    * net-smtp
-    * open3
-    * pstore
-    * singleton
-  * The following default gems only promoted ruby-core, Not yet published at rubygems.org.
-    * monitor
-    * observer
-    * timeout
-    * tracer
-    * uri
-    * yaml
-
-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. No one maintains it from 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+
-  https://github.com/ruby/ruby/pull/2404
-
-=== Implementation improvements
-
-Fiber::
-
-  * Allow selecting different coroutine implementation 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.
-
-File::
-  * File.realpath now uses realpath(3) on many platforms, which can
-    significantly improve performance.
-
-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. ~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.
-
-  * Default value of +--jit-max-cache+ is changed from 1,000 to 100
-
-  * Default value of +--jit-min-calls+ is changed from 5 to 10,000
-
-RubyVM::InstructionSequence::
-
-  * RubyVM::InstructionSequence#to_binary method generate 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-trunk/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 `__builtin_` 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.
-
-* Per-call-site method cache, which has been there since around 1.9, was
-  improved: cache hit rate raised from 89% to 94%.

+# NEWS for Ruby 3.2.0
+
+This document is a list of user-visible feature changes
+since the **3.1.0** release, except for bug fixes.
+
+Note that each entry is kept to a minimum, see links for details.
+
+## Language changes
+
+* Anonymous rest and keyword rest arguments can now be passed as
+  arguments, instead of just used in method parameters.
+  [[Feature #18351]]
+
+    ```ruby
+    def foo(*)
+      bar(*)
+    end
+    def baz(**)
+      quux(**)
+    end
+    ```
+
+* A proc that accepts a single positional argument and keywords will
+  no longer autosplat. [[Bug #18633]]
+
+    ```ruby
+    proc{|a, **k| a}.call([1, 2])
+    # Ruby 3.1 and before
+    # => 1
+    # Ruby 3.2 and after
+    # => [1, 2]
+    ```
+
+* Constant assignment evaluation order for constants set on explicit
+  objects has been made consistent with single attribute assignment
+  evaluation order. With this code:
+
+    ```ruby
+    foo::BAR = baz
+    ```
+
+    `foo` is now called before `baz`. Similarly, for multiple assignments
+    to constants,  left-to-right evaluation order is used. With this
+    code:
+
+    ```ruby
+    foo1::BAR1, foo2::BAR2 = baz1, baz2
+    ```
+
+    The following evaluation order is now used:
+
+    1. `foo1`
+    2. `foo2`
+    3. `baz1`
+    4. `baz2`
+
+    [[Bug #15928]]
+
+* "Find pattern" is no longer experimental.
+  [[Feature #18585]]
+
+* Methods taking a rest parameter (like `*args`) and wishing to delegate keyword
+  arguments through `foo(*args)` must now be marked with `ruby2_keywords`
+  (if not already the case). In other words, all methods wishing to delegate
+  keyword arguments through `*args` must now be marked with `ruby2_keywords`,
+  with no exception. This will make it easier to transition to other ways of
+  delegation once a library can require Ruby 3+. Previously, the `ruby2_keywords`
+  flag was kept if the receiving method took `*args`, but this was a bug and an
+  inconsistency. A good technique to find the potentially-missing `ruby2_keywords`
+  is to run the test suite, for where it fails find the last method which must
+  receive keyword arguments, use `puts nil, caller, nil` there, and check each
+  method/block on the call chain which must delegate keywords is correctly marked
+  as `ruby2_keywords`. [[Bug #18625]] [[Bug #16466]]
+
+    ```ruby
+    def target(**kw)
+    end
+
+    # Accidentally worked without ruby2_keywords in Ruby 2.7-3.1, ruby2_keywords
+    # needed in 3.2+. Just like (*args, **kwargs) or (...) would be needed on
+    # both #foo and #bar when migrating away from ruby2_keywords.
+    ruby2_keywords def bar(*args)
+      target(*args)
+    end
+
+    ruby2_keywords def foo(*args)
+      bar(*args)
+    end
+
+    foo(k: 1)
+    ```
+
+## Core classes updates
+
+Note: We're only listing outstanding class updates.
+
+* Fiber
+
+    * Introduce Fiber.[] and Fiber.[]= for inheritable fiber storage.
+      Introduce Fiber#storage and Fiber#storage= (experimental) for
+      getting and resetting the current storage.  Introduce
+      `Fiber.new(storage:)` for setting the storage when creating a
+      fiber. [[Feature #19078]]
+
+        Existing Thread and Fiber local variables can be tricky to use.
+        Thread-local variables are shared between all fibers, making it
+        hard to isolate, while Fiber-local variables can be hard to
+        share.  It is often desirable to define unit of execution
+        ("execution context") such that some state is shared between all
+        fibers and threads created in that context.  This is what Fiber
+        storage provides.
+
+        ```ruby
+        def log(message)
+          puts "#{Fiber[:request_id]}: #{message}"
+        end
+
+        def handle_requests
+          while request = read_request
+            Fiber.schedule do
+              Fiber[:request_id] = SecureRandom.uuid
+
+              request.messages.each do |message|
+                Fiber.schedule do
+                  log("Handling #{message}") # Log includes inherited request_id.
+                end
+              end
+            end
+          end
+        end
+        ```
+
+        You should generally consider Fiber storage for any state which
+        you want to be shared implicitly between all fibers and threads
+        created in a given context, e.g. a connection pool, a request
+        id, a logger level, environment variables, configuration, etc.
+
+* Fiber::Scheduler
+
+    * Introduce `Fiber::Scheduler#io_select` for non-blocking IO.select.
+      [[Feature #19060]]
+
+* IO
+
+    * Introduce IO#timeout= and IO#timeout which can cause
+      IO::TimeoutError to be raised if a blocking operation exceeds the
+      specified timeout. [[Feature #18630]]
+
+        ```ruby
+        STDIN.timeout = 1
+        STDIN.read # => Blocking operation timed out! (IO::TimeoutError)
+        ```
+
+    * Introduce `IO.new(..., path:)` and promote `File#path` to `IO#path`.
+      [[Feature #19036]]
+
+* Class
+
+    * Class#attached_object, which returns the object for which
+      the receiver is the singleton class. Raises TypeError if the
+      receiver is not a singleton class.
+      [[Feature #12084]]
+
+        ```ruby
+        class Foo; end
+
+        Foo.singleton_class.attached_object        #=> Foo
+        Foo.new.singleton_class.attached_object    #=> #<Foo:0x000000010491a370>
+        Foo.attached_object                        #=> TypeError: `Foo' is not a singleton class
+        nil.singleton_class.attached_object        #=> TypeError: `NilClass' is not a singleton class
+        ```
+
+* Data
+
+    * New core class to represent simple immutable value object. The class is
+      similar to Struct and partially shares an implementation, but has more
+      lean and strict API. [[Feature #16122]]
+
+        ```ruby
+        Measure = Data.define(:amount, :unit)
+        distance = Measure.new(100, 'km')            #=> #<data Measure amount=100, unit="km">
+        weight = Measure.new(amount: 50, unit: 'kg') #=> #<data Measure amount=50, unit="kg">
+        weight.with(amount: 40)                      #=> #<data Measure amount=40, unit="kg">
+        weight.amount                                #=> 50
+        weight.amount = 40                           #=> NoMethodError: undefined method `amount='
+        ```
+
+* Encoding
+
+    * Encoding#replicate has been deprecated and will be removed in 3.3. [[Feature #18949]]
+    * The dummy `Encoding::UTF_16` and `Encoding::UTF_32` encodings no longer
+      try to dynamically guess the endian based on a byte order mark.
+      Use `Encoding::UTF_16BE`/`UTF_16LE` and `Encoding::UTF_32BE`/`UTF_32LE` instead.
+      This change speeds up getting the encoding of a String. [[Feature #18949]]
+    * Limit maximum encoding set size by 256.
+      If exceeding maximum size, `EncodingError` will be raised. [[Feature #18949]]
+
+* Enumerator
+
+    * Enumerator.product has been added.  Enumerator::Product is the implementation. [[Feature #18685]]
+
+* Exception
+
+    * Exception#detailed_message has been added.
+      The default error printer calls this method on the Exception object
+      instead of #message. [[Feature #18564]]
+
+* Hash
+
+    * Hash#shift now always returns nil if the hash is
+      empty, instead of returning the default value or
+      calling the default proc. [[Bug #16908]]
+
+* Integer
+
+    * Integer#ceildiv has been added. [[Feature #18809]]
+
+* Kernel
+
+    * Kernel#binding raises RuntimeError if called from a non-Ruby frame
+      (such as a method defined in C). [[Bug #18487]]
+
+* MatchData
+
+    * MatchData#byteoffset has been added. [[Feature #13110]]
+    * MatchData#deconstruct has been added. [[Feature #18821]]
+    * MatchData#deconstruct_keys has been added. [[Feature #18821]]
+
+* Module
+
+    * Module.used_refinements has been added. [[Feature #14332]]
+    * Module#refinements has been added. [[Feature #12737]]
+    * Module#const_added has been added. [[Feature #17881]]
+    * Module#undefined_instance_methods has been added. [[Feature #12655]]
+
+* Proc
+
+    * Proc#dup returns an instance of subclass. [[Bug #17545]]
+    * Proc#parameters now accepts lambda keyword. [[Feature #15357]]
+
+* Process
+    * Added `RLIMIT_NPTS` constant to FreeBSD platform
+
+* Regexp
+
+    * The cache-based optimization is introduced.
+      Many (but not all) Regexp matching is now in linear time, which
+      will prevent regular expression denial of service (ReDoS)
+      vulnerability. [[Feature #19104]]
+
+    * Regexp.linear_time? is introduced. [[Feature #19194]]
+
+    * Regexp.new now supports passing the regexp flags not only as an Integer,
+      but also as a String.  Unknown flags raise ArgumentError.
+      Otherwise, anything other than `true`, `false`, `nil` or Integer will be warned.
+      [[Feature #18788]]
+
+    * Regexp.timeout= has been added. Also, Regexp.new new supports timeout keyword.
+      See [[Feature #17837]]
+
+* Refinement
+
+    * Refinement#refined_class has been added. [[Feature #12737]]
+
+* RubyVM::AbstractSyntaxTree
+
+    * Add `error_tolerant` option for `parse`, `parse_file` and `of`. [[Feature #19013]]
+      With this option
+
+        1. SyntaxError is suppressed
+        2. AST is returned for invalid input
+        3. `end` is complemented when a parser reaches to the end of input but `end` is insufficient
+        4. `end` is treated as keyword based on indent
+
+        ```ruby
+        # Without error_tolerant option
+        root = RubyVM::AbstractSyntaxTree.parse(<<~RUBY)
+        def m
+          a = 10
+          if
+        end
+        RUBY
+        # => <internal:ast>:33:in `parse': syntax error, unexpected `end' (SyntaxError)
+
+        # With error_tolerant option
+        root = RubyVM::AbstractSyntaxTree.parse(<<~RUBY, error_tolerant: true)
+        def m
+          a = 10
+          if
+        end
+        RUBY
+        p root # => #<RubyVM::AbstractSyntaxTree::Node:SCOPE@1:0-4:3>
+
+        # `end` is treated as keyword based on indent
+        root = RubyVM::AbstractSyntaxTree.parse(<<~RUBY, error_tolerant: true)
+        module Z
+          class Foo
+            foo.
+          end
+
+          def bar
+          end
+        end
+        RUBY
+        p root.children[-1].children[-1].children[-1].children[-2..-1]
+        # => [#<RubyVM::AbstractSyntaxTree::Node:CLASS@2:2-4:5>, #<RubyVM::AbstractSyntaxTree::Node:DEFN@6:2-7:5>]
+        ```
+
+    * Add `keep_tokens` option for `parse`, `parse_file` and `of`. Add `#tokens` and `#all_tokens`
+      for RubyVM::AbstractSyntaxTree::Node [[Feature #19070]]
+
+        ```ruby
+        root = RubyVM::AbstractSyntaxTree.parse("x = 1 + 2", keep_tokens: true)
+        root.tokens # => [[0, :tIDENTIFIER, "x", [1, 0, 1, 1]], [1, :tSP, " ", [1, 1, 1, 2]], ...]
+        root.tokens.map{_1[2]}.join # => "x = 1 + 2"
+        ```
+
+* Set
+
+    * Set is now available as a built-in class without the need for `require "set"`. [[Feature #16989]]
+      It is currently autoloaded via the Set constant or a call to Enumerable#to_set.
+
+* String
+
+    * String#byteindex and String#byterindex have been added. [[Feature #13110]]
+    * Update Unicode to Version 15.0.0 and Emoji Version 15.0. [[Feature #18639]]
+      (also applies to Regexp)
+    * String#bytesplice has been added.  [[Feature #18598]]
+    * String#dedup has been added as an alias to String#-@.  [[Feature #18595]]
+
+* Struct
+
+    * A Struct class can also be initialized with keyword arguments
+      without `keyword_init: true` on Struct.new [[Feature #16806]]
+
+        ```ruby
+        Post = Struct.new(:id, :name)
+        Post.new(1, "hello") #=> #<struct Post id=1, name="hello">
+        # From Ruby 3.2, the following code also works without keyword_init: true.
+        Post.new(id: 1, name: "hello") #=> #<struct Post id=1, name="hello">
+        ```
+
+* Thread
+
+    * Thread.each_caller_location is added. [[Feature #16663]]
+
+* Thread::Queue
+
+    * Thread::Queue#pop(timeout: sec) is added. [[Feature #18774]]
+
+* Thread::SizedQueue
+
+    * Thread::SizedQueue#pop(timeout: sec) is added. [[Feature #18774]]
+    * Thread::SizedQueue#push(timeout: sec) is added. [[Feature #18944]]
+
+* Time
+
+    * Time#deconstruct_keys is added, allowing to use Time instances
+      in pattern-matching expressions [[Feature #19071]]
+
+    * Time.new now can parse a string like generated by Time#inspect
+      and return a Time instance based on the given argument.
+      [[Feature #18033]]
+
+* SyntaxError
+    * SyntaxError#path has been added.  [[Feature #19138]]
+
+* TracePoint
+
+    * TracePoint#binding now returns `nil` for `c_call`/`c_return` TracePoints.
+      [[Bug #18487]]
+    * TracePoint#enable `target_thread` keyword argument now defaults to the
+      current thread if a block is given and `target` and `target_line` keyword
+      arguments are not passed. [[Bug #16889]]
+
+* UnboundMethod
+
+    * `UnboundMethod#==` returns `true` if the actual method is same. For example,
+      `String.instance_method(:object_id) == Array.instance_method(:object_id)`
+      returns `true`. [[Feature #18798]]
+
+    * `UnboundMethod#inspect` does not show the receiver of `instance_method`.
+      For example `String.instance_method(:object_id).inspect` returns
+      `"#<UnboundMethod: Kernel#object_id()>"`
+      (was `"#<UnboundMethod: String(Kernel)#object_id()>"`).
+
+* GC
+
+    * Expose `need_major_gc` via `GC.latest_gc_info`. [GH-6791]
+
+* ObjectSpace
+
+    * `ObjectSpace.dump_all` dump shapes as well. [GH-6868]
+
+## Stdlib updates
+
+* Bundler
+
+    * Bundler now uses [PubGrub] resolver instead of [Molinillo] for performance improvement.
+    * Add --ext=rust support to bundle gem for creating simple gems with Rust extensions.
+      [[GH-rubygems-6149]]
+    * Make cloning git repos faster [[GH-rubygems-4475]]
+
+* RubyGems
+
+    * Add mswin support for cargo builder. [[GH-rubygems-6167]]
+
+* CGI
+
+    * `CGI.escapeURIComponent` and `CGI.unescapeURIComponent` are added.
+      [[Feature #18822]]
+
+* Coverage
+
+    * `Coverage.setup` now accepts `eval: true`. By this, `eval` and related methods are
+      able to generate code coverage. [[Feature #19008]]
+
+    * `Coverage.supported?(mode)` enables detection of what coverage modes are
+      supported. [[Feature #19026]]
+
+* Date
+
+    * Added `Date#deconstruct_keys` and `DateTime#deconstruct_keys` same as [[Feature #19071]]
+
+* ERB
+
+    * `ERB::Util.html_escape` is made faster than `CGI.escapeHTML`.
+        * It no longer allocates a String object when no character needs to be escaped.
+        * It skips calling `#to_s` method when an argument is already a String.
+        * `ERB::Escape.html_escape` is added as an alias to `ERB::Util.html_escape`,
+          which has not been monkey-patched by Rails.
+    * `ERB::Util.url_encode` is made faster using `CGI.escapeURIComponent`.
+    * `-S` option is removed from `erb` command.
+
+* FileUtils
+
+    * Add FileUtils.ln_sr method and `relative:` option to FileUtils.ln_s.
+      [[Feature #18925]]
+
+* IRB
+
+    * debug.gem integration commands have been added: `debug`, `break`, `catch`,
+      `next`, `delete`, `step`, `continue`, `finish`, `backtrace`, `info`
+        * They work even if you don't have `gem "debug"` in your Gemfile.
+        * See also: [What's new in Ruby 3.2's IRB?](https://st0012.dev/whats-new-in-ruby-3-2-irb)
+    * More Pry-like commands and features have been added.
+        * `edit` and `show_cmds` (like Pry's `help`) are added.
+        * `ls` takes `-g` or `-G` option to filter out outputs.
+        * `show_source` is aliased from `$` and accepts unquoted inputs.
+        * `whereami` is aliased from `@`.
+
+* Net::Protocol
+
+    * Improve `Net::BufferedIO` performance. [[GH-net-protocol-14]]
+
+* Pathname
+
+    * Added `Pathname#lutime`. [[GH-pathname-20]]
+
+* Socket
+
+    * Added the following constants for supported platforms.
+        * `SO_INCOMING_CPU`
+        * `SO_INCOMING_NAPI_ID`
+        * `SO_RTABLE`
+        * `SO_SETFIB`
+        * `SO_USER_COOKIE`
+        * `TCP_KEEPALIVE`
+        * `TCP_CONNECTION_INFO`
+
+* SyntaxSuggest
+
+    * The feature of `syntax_suggest` formerly `dead_end` is integrated in Ruby.
+      [[Feature #18159]]
+
+* UNIXSocket
+
+    * Add support for UNIXSocket on Windows. Emulate anonymous sockets. Add
+      support for File.socket? and File::Stat#socket? where possible.
+      [[Feature #19135]]
+
+*   The following default gems are updated.
+
+    * RubyGems 3.4.1
+    * abbrev 0.1.1
+    * benchmark 0.2.1
+    * bigdecimal 3.1.3
+    * bundler 2.4.1
+    * cgi 0.3.6
+    * csv 3.2.6
+    * date 3.3.3
+    * delegate 0.3.0
+    * did_you_mean 1.6.3

+
+## Supported platforms
+
+* WebAssembly/WASI is added. See [wasm/README.md] and [ruby.wasm] for more details. [[Feature #18462]]
+
+## Compatibility issues
+
+* `String#to_c` currently treat a sequence of underscores as an end of Complex
+  string. [[Bug #19087]]
+
+* Now `ENV.clone` raises `TypeError` as well as `ENV.dup` [[Bug #17767]]
+
+### Removed constants
+
+The following deprecated constants are removed.
+
+* `Fixnum` and `Bignum` [[Feature #12005]]
+* `Random::DEFAULT` [[Feature #17351]]
+* `Struct::Group`
+* `Struct::Passwd`
+
+### Removed methods
+
+The following deprecated methods are removed.
+
+* `Dir.exists?` [[Feature #17391]]
+* `File.exists?` [[Feature #17391]]
+* `Kernel#=~` [[Feature #15231]]
+* `Kernel#taint`, `Kernel#untaint`, `Kernel#tainted?`
+  [[Feature #16131]]
+* `Kernel#trust`, `Kernel#untrust`, `Kernel#untrusted?`
+  [[Feature #16131]]
+* `Method#public?`, `Method#private?`, `Method#protected?`,
+  `UnboundMethod#public?`, `UnboundMethod#private?`, `UnboundMethod#protected?`
+  [[Bug #18729]] [[Bug #18751]] [[Bug #18435]]
+
+### Source code incompatibility of extension libraries
+
+* Extension libraries provide PRNG, subclasses of Random, need updates.
+  See [PRNG update] below for more information. [[Bug #19100]]
+
+### Error printer
+
+* Ruby no longer escapes control characters and backslashes in an
+  error message. [[Feature #18367]]
+
+### Constant lookup when defining a class/module
+
+* When defining a class/module directly under the Object class by class/module
+  statement, if there is already a class/module defined by `Module#include`
+  with the same name, the statement was handled as "open class" in Ruby 3.1 or before.
+  Since Ruby 3.2, a new class is defined instead. [[Feature #18832]]
+
+## Stdlib compatibility issues
+
+* Psych no longer bundles libyaml sources.
+  And also Fiddle no longer bundles libffi sources.
+  Users need to install the libyaml/libffi library themselves via the package
+  manager like apt, yum, brew, etc.
+
+    Psych and fiddle supported the static build with specific version of libyaml
+    and libffi sources. You can build psych with libyaml-0.2.5 like this.
+
+    ```bash
+    $ ./configure --with-libyaml-source-dir=/path/to/libyaml-0.2.5
+    ```
+
+    And you can build fiddle with libffi-3.4.4 like this.
+
+    ```bash
+    $ ./configure --with-libffi-source-dir=/path/to/libffi-3.4.4
+    ```
+
+    [[Feature #18571]]
+
+* Check cookie name/path/domain characters in `CGI::Cookie`. [[CVE-2021-33621]]
+
+* `URI.parse` return empty string in host instead of nil. [[sec-156615]]
+
+## C API updates
+
+### Updated C APIs
+
+The following APIs are updated.
+
+* PRNG update
+
+    `rb_random_interface_t` in ruby/random.h updated and versioned.
+    Extension libraries which use this interface and built for older
+    versions need to rebuild with adding `init_int32` function.
+
+### Added C APIs
+
+* `VALUE rb_hash_new_capa(long capa)` was added to created hashes with the desired capacity.
+* `rb_internal_thread_add_event_hook` and `rb_internal_thread_add_event_hook` were added to instrument threads scheduling.
+  The following events are available:
+    * `RUBY_INTERNAL_THREAD_EVENT_STARTED`
+    * `RUBY_INTERNAL_THREAD_EVENT_READY`
+    * `RUBY_INTERNAL_THREAD_EVENT_RESUMED`
+    * `RUBY_INTERNAL_THREAD_EVENT_SUSPENDED`
+    * `RUBY_INTERNAL_THREAD_EVENT_EXITED`
+* `rb_debug_inspector_current_depth` and `rb_debug_inspector_frame_depth` are added for debuggers.
+
+### Removed C APIs
+
+The following deprecated APIs are removed.
+
+* `rb_cData` variable.
+* "taintedness" and "trustedness" functions. [[Feature #16131]]
+
+## Implementation improvements
+
+* Fixed several race conditions in Kernel#autoload. [[Bug #18782]]
+* Cache invalidation for expressions referencing constants is now
+  more fine-grained. `RubyVM.stat(:global_constant_state)` was
+  removed because it was closely tied to the previous caching scheme
+  where setting any constant invalidates all caches in the system.
+  New keys, `:constant_cache_invalidations` and `:constant_cache_misses`,
+  were introduced to help with use cases for `:global_constant_state`.
+  [[Feature #18589]]
+* The cache-based optimization for Regexp matching is introduced.
+  [[Feature #19104]]
+* [Variable Width Allocation](https://shopify.engineering/ruby-variable-width-allocation)
+  is now enabled by default. [[Feature #18239]]
+* Added a new instance variable caching mechanism, called object shapes, which
+  improves inline cache hits for most objects and allows us to generate very
+  efficient JIT code. Objects whose instance variables are defined in a
+  consistent order will see the most performance benefits.
+  [[Feature #18776]]
+* Speed up marking instruction sequences by using a bitmap to find "markable"
+  objects.  This change results in faster major collections.
+  [[Feature #18875]]
+
+## JIT
+
+### YJIT
+
+* YJIT is no longer experimental
+    * Has been tested on production workloads for over a year and proven to be quite stable.
+* YJIT now supports both x86-64 and arm64/aarch64 CPUs on Linux, MacOS, BSD and other UNIX platforms.
+    * This release brings support for Mac M1/M2, AWS Graviton and Raspberry Pi 4.
+* Building YJIT now requires Rust 1.58.0+. [[Feature #18481]]
+    * In order to ensure that CRuby is built with YJIT, please install `rustc` >= 1.58.0
+      before running `./configure`
+    * Please reach out to the YJIT team should you run into any issues.
+* Physical memory for JIT code is lazily allocated. Unlike Ruby 3.1,
+  the RSS of a Ruby process is minimized because virtual memory pages
+  allocated by `--yjit-exec-mem-size` will not be mapped to physical
+  memory pages until actually utilized by JIT code.
+* Introduce Code GC that frees all code pages when the memory consumption
+  by JIT code reaches `--yjit-exec-mem-size`.
+    * `RubyVM::YJIT.runtime_stats` returns Code GC metrics in addition to
+      existing `inline_code_size` and `outlined_code_size` keys:
+      `code_gc_count`, `live_page_count`, `freed_page_count`, and `freed_code_size`.
+* Most of the statistics produced by `RubyVM::YJIT.runtime_stats` are now available in release builds.
+    * Simply run ruby with `--yjit-stats` to compute and dump stats (incurs some run-time overhead).
+* YJIT is now optimized to take advantage of object shapes. [[Feature #18776]]
+* Take advantage of finer-grained constant invalidation to invalidate less code when defining new constants. [[Feature #18589]]
+* The default `--yjit-exec-mem-size` is changed to 64 (MiB).
+* The default `--yjit-call-threshold` is changed to 30.
+
+### MJIT
+
+* The MJIT compiler is re-implemented in Ruby as `ruby_vm/mjit/compiler`.
+* MJIT compiler is executed under a forked Ruby process instead of
+  doing it in a native thread called MJIT worker. [[Feature #18968]]
+    * As a result, Microsoft Visual Studio (MSWIN) is no longer supported.
+* MinGW is no longer supported. [[Feature #18824]]
+* Rename `--mjit-min-calls` to `--mjit-call-threshold`.
+* Change default `--mjit-max-cache` back from 10000 to 100.

-## 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.  If `./configure` does not exist or is older than `configure.ac`, run
-    `autoconf` to (re)generate configure.
-
-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 `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`.
+in the mail body (not subject) to the address [ruby-talk-request@ruby-lang.org].
 
-    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.  Optionally, run `make update-gems` and `make extract-gems`.
-
-    If you want to install bundled gems, run `make update-gems` and
-    `make extract-gems` before running `make install`.
-
-9.  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}/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.

+ *
+ * 1:   RARRAY_EMBED_FLAG
+ *          The array is embedded (its contents follow the header, rather than
+ *          being on a separately allocated buffer).
+ * 2:   RARRAY_SHARED_FLAG (equal to ELTS_SHARED)
+ *          The array is shared. The buffer this array points to is owned by
+ *          another array (the shared root).
+ * if USE_RVARGC
+ * 3-9: RARRAY_EMBED_LEN
+ *          The length of the array when RARRAY_EMBED_FLAG is set.
+ * else
+ * 3-4: RARRAY_EMBED_LEN
+ *          The length of the array when RARRAY_EMBED_FLAG is set.
+ * endif
+ * 12:  RARRAY_SHARED_ROOT_FLAG
+ *          The array is a shared root that does reference counting. The buffer
+ *          this array points to is owned by this array but may be pointed to
+ *          by other arrays.
+ *          Note: Frozen arrays may be a shared root without this flag being
+ *                set. Frozen arrays do not have reference counting because
+ *                they cannot be modified. Not updating the reference count
+ *                improves copy-on-write performance. Their reference count is
+ *                assumed to be infinity.
+ * 13:  RARRAY_TRANSIENT_FLAG
+ *          The buffer of the array is allocated on the transient heap.
+ * 14:  RARRAY_PTR_IN_USE_FLAG
+ *          The buffer of the array is in use. This is only used during
+ *          debugging.

  *
- *  In the first form, if no arguments are sent, the new array will be empty.
- *  When a +size+ and an optional +default+ are sent, an array is created with
- *  +size+ copies of +default+.  Take notice that all elements will reference the
- *  same object +default+.
+ *  Returns a new \Array.
  *
- *  The second form creates a copy of the array passed as a parameter (the
- *  array is generated by calling to_ary on the parameter).
+ *  With no block and no arguments, returns a new empty \Array object.
  *
- *    first_array = ["Matz", "Guido"]
+ *  With no block and a single \Array argument +array+,
+ *  returns a new \Array formed from +array+:
  *

+ *    a = Array.new([:foo, 'bar', 2])
+ *    a.class # => Array
+ *    a # => [:foo, "bar", 2]
  *
- *    first_array.equal? second_array       #=> false
+ *  With no block and a single \Integer argument +size+,
+ *  returns a new \Array of the given size
+ *  whose elements are all +nil+:
  *
- *  In the last form, an array of the given size is created.  Each element in
- *  this array is created by passing the element's index to the given block
- *  and storing the return value.
+ *    a = Array.new(3)
+ *    a # => [nil, nil, nil]
  *
- *    Array.new(3) {|index| index ** 2}
- *    # => [0, 1, 4]
+ *  With no block and arguments +size+ and +default_value+,
+ *  returns an \Array of the given size;
+ *  each element is that same +default_value+:
  *
- *  == Common gotchas
+ *    a = Array.new(3, 'x')
+ *    a # => ['x', 'x', 'x']
  *
- *  When sending the second parameter, the same object will be used as the
- *  value for all the array elements:
+ *  With a block and argument +size+,
+ *  returns an \Array of the given size;
+ *  the block is called with each successive integer +index+;
+ *  the element for that +index+ is the return value from the block:
  *
- *     a = Array.new(2, Hash.new)
- *     # => [{}, {}]
+ *    a = Array.new(3) {|index| "Element #{index}" }
+ *    a # => ["Element 0", "Element 1", "Element 2"]
  *
- *     a[0]['cat'] = 'feline'
- *     a # => [{"cat"=>"feline"}, {"cat"=>"feline"}]
- *
- *     a[1]['cat'] = 'Felix'
- *     a # => [{"cat"=>"Felix"}, {"cat"=>"Felix"}]
- *
- *  Since all the Array elements store the same hash, changes to one of them
- *  will affect them all.
- *
- *  If multiple copies are what you want, you should use the block
- *  version which uses the result of that block each time an element
- *  of the array needs to be initialized:
- *
- *     a = Array.new(2) {Hash.new}
- *     a[0]['cat'] = 'feline'
- *     a # => [{"cat"=>"feline"}, {}]
+ *  Raises ArgumentError if +size+ is negative.
  *
+ *  With a block and no argument,
+ *  or a single argument +0+,
+ *  ignores the block and returns a new empty \Array.

- *  Each object in each array is compared (using the <=> operator).
+ *    [0, 1, 2] <=> [0, 1, 1] # => 1
  *
- *  Arrays are compared in an "element-wise" manner; the first element of +ary+
- *  is compared with the first one of +other_ary+ using the <=> operator, then
- *  each of the second elements, etc...
- *  As soon as the result of any such comparison is non zero (i.e. the two
- *  corresponding elements are not equal), that result is returned for the
- *  whole array comparison.
+ *  When all results are zero:
  *
- *  If all the elements are equal, then the result is based on a comparison of
- *  the array lengths. Thus, two arrays are "equal" according to Array#<=> if,
- *  and only if, they have the same length and the value of each element is
- *  equal to the value of the corresponding element in the other array.
+ *  - Returns -1 if +array+ is smaller than +other_array+:
  *
- *  +nil+ is returned if the +other_ary+ is not an array or if the comparison
- *  of two elements returned +nil+.
+ *      [0, 1, 2] <=> [0, 1, 2, 3] # => -1

- *     [ 1, 2 ]             <=> [ 1, :two ]         #=> nil
+ *  - Returns 1 if +array+ is larger than +other_array+:
+ *
+ *      [0, 1, 2] <=> [0, 1] # => 1
+ *
+ *  - Returns 0 if +array+ and +other_array+ are the same size:

 /*
- *  Arrays are ordered, integer-indexed collections of any object.
+ *  An \Array is an ordered, integer-indexed collection of objects, called _elements_.
+ *  Any object (even another array) may be an array element,
+ *  and an array can contain objects of different types.
+ *
+ *  == \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 and only 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 and only 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.
+ *
+ *  Although the effective index into an array is always an integer,
+ *  some methods (both within and outside of class \Array)
+ *  accept one or more non-integer arguments that are
+ *  {integer-convertible objects}[rdoc-ref:implicit_conversion.rdoc@Integer-Convertible+Objects].
  *
- *  Array indexing starts at 0, as in C or Java.  A negative index is assumed
- *  to be relative to the end of the array---that is, an index of -1 indicates
- *  the last element of the array, -2 is the next to last element in the
- *  array, and so on.
  *
  *  == 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:
+ *  You can create an \Array object explicitly with:
+ *
+ *  - An {array literal}[rdoc-ref:literals.rdoc@Array+Literals]:
  *
- *     ary = [1, "two", 3.0] #=> [1, "two", 3.0]
+ *      [1, 'one', :one, [2, 'two', :two]]
  *
- *  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).
+ *  - A {%w or %W: string-array Literal}[rdoc-ref:literals.rdoc@25w+and+-25W-3A+String-Array+Literals]:
  *
- *     ary = Array.new    #=> []
- *     Array.new(3)       #=> [nil, nil, nil]
- *     Array.new(3, true) #=> [true, true, true]
+ *      %w[foo bar baz] # => ["foo", "bar", "baz"]
+ *      %w[1 % *]       # => ["1", "%", "*"]
  *
- *  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.
+ *  - A {%i pr %I: symbol-array Literal}[rdoc-ref:literals.rdoc@25i+and+-25I-3A+Symbol-Array+Literals]:
  *
- *  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:
+ *      %i[foo bar baz] # => [:foo, :bar, :baz]
+ *      %i[1 % *]       # => [:"1", :%, :*]
  *
- *     Array.new(4) {Hash.new}    #=> [{}, {}, {}, {}]
- *     Array.new(4) {|i| i.to_s } #=> ["0", "1", "2", "3"]
+ *  - \Method Kernel#Array:
  *
- *  This is also a quick way to build up multi-dimensional arrays:
+ *      Array(["a", "b"])             # => ["a", "b"]
+ *      Array(1..5)                   # => [1, 2, 3, 4, 5]
+ *      Array(key: :value)            # => [[:key, :value]]
+ *      Array(nil)                    # => []
+ *      Array(1)                      # => [1]
+ *      Array({:a => "a", :b => "b"}) # => [[:a, "a"], [:b, "b"]]
  *
- *     empty_table = Array.new(3) {Array.new(3)}
- *     #=> [[nil, nil, nil], [nil, nil, nil], [nil, nil, nil]]
+ *  - \Method Array.new:
  *
- *  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.new               # => []
+ *      Array.new(3)            # => [nil, nil, nil]
+ *      Array.new(4) {Hash.new} # => [{}, {}, {}, {}]
+ *      Array.new(3, true)      # => [true, true, true]
  *
- *	Array({:a => "a", :b => "b"}) #=> [[:a, "a"], [:b, "b"]]
+ *    Note that the last example above populates the array
+ *    with references to the same object.
+ *    This is recommended only in cases where that object is a natively immutable object
+ *    such as a symbol, a numeric, +nil+, +true+, or +false+.
+ *
+ *    Another way to create an array with various objects, using a block;
+ *    this usage is safe for mutable objects such as hashes, strings or
+ *    other arrays:
+ *
+ *      Array.new(4) {|i| i.to_s } # => ["0", "1", "2", "3"]
+ *
+ *    Here is a way to create a multi-dimensional array:
+ *
+ *      Array.new(3) {Array.new(3)}
+ *      # => [[nil, nil, nil], [nil, nil, nil], [nil, nil, nil]]
+ *
+ *  A number of Ruby methods, both in the core and in the standard library,
+ *  provide instance method +to_a+, which converts an object to an array.

+          In many cases you will need to enclose your source code in single or double quotes.
+
+          If source code is not specified, it will default to 'self',
+          which is most likely useful only in a filter mode (-ml, -me, -mb).
+
+          If there is a .rexerc file in your home directory, it will be run as Ruby code
+          before processing the input.
+
+          If there is a REXE_OPTIONS environment variable, its content will be prepended
+          to the command line so that you can specify options implicitly
+          (e.g. `export REXE_OPTIONS="-r amazing_print,yaml"`)

 /*
+ *  Document-class: Data
+ *
+ *  \Class \Data provides a convenient way to define simple classes
+ *  for value-alike objects.
+ *
+ *  The simplest example of usage:
+ *
+ *     Measure = Data.define(:amount, :unit)
+ *
+ *     # Positional arguments constructor is provided
+ *     distance = Measure.new(100, 'km')
+ *     #=> #<data Measure amount=100, unit="km">
+ *
+ *     # Keyword arguments constructor is provided
+ *     weight = Measure.new(amount: 50, unit: 'kg')
+ *     #=> #<data Measure amount=50, unit="kg">
+ *
+ *     # Alternative form to construct an object:
+ *     speed = Measure[10, 'mPh']
+ *     #=> #<data Measure amount=10, unit="mPh">
+ *
+ *     # Works with keyword arguments, too:
+ *     area = Measure[amount: 1.5, unit: 'm^2']
+ *     #=> #<data Measure amount=1.5, unit="m^2">
+ *
+ *     # Argument accessors are provided:
+ *     distance.amount #=> 100
+ *     distance.unit #=> "km"
+ *
+ *  Constructed object also has a reasonable definitions of #==
+ *  operator, #to_h hash conversion, and #deconstruct/#deconstruct_keys
+ *  to be used in pattern matching.
+ *
+ *  ::define method accepts an optional block and evaluates it in
+ *  the context of the newly defined class. That allows to define
+ *  additional methods:
+ *
+ *     Measure = Data.define(:amount, :unit) do
+ *       def <=>(other)
+ *         return unless other.is_a?(self.class) && other.unit == unit
+ *         amount <=> other.amount
+ *       end
+ *
+ *       include Comparable
+ *     end
+ *
+ *     Measure[3, 'm'] < Measure[5, 'm'] #=> true
+ *     Measure[3, 'm'] < Measure[5, 'kg']
+ *     # comparison of Measure with Measure failed (ArgumentError)
+ *
+ *  Data provides no member writers, or enumerators: it is meant
+ *  to be a storage for immutable atomic values. But note that
+ *  if some of data members is of a mutable class, Data does no additional
+ *  immutability enforcement:
+ *
+ *     Event = Data.define(:time, :weekdays)
+ *     event = Event.new('18:00', %w[Tue Wed Fri])
+ *     #=> #<data Event time="18:00", weekdays=["Tue", "Wed", "Fri"]>
+ *
+ *     # There is no #time= or #weekdays= accessors, but changes are
+ *     # still possible:
+ *     event.weekdays << 'Sat'
+ *     event
+ *     #=> #<data Event time="18:00", weekdays=["Tue", "Wed", "Fri", "Sat"]>
+ *
+ *  See also Struct, which is a similar concept, but has more
+ *  container-alike API, allowing to change contents of the object
+ *  and enumerate it.
+ */
+
+/*
+ * call-seq:
+ *   define(*symbols) -> class
+ *
+ *  Defines a new \Data class.
+ *
+ *     measure = Data.define(:amount, :unit)
+ *     #=> #<Class:0x00007f70c6868498>
+ *     measure.new(1, 'km')
+ *     #=> #<data amount=1, unit="km">
+ *
+ *     # It you store the new class in the constant, it will
+ *     # affect #inspect and will be more natural to use:
+ *     Measure = Data.define(:amount, :unit)
+ *     #=> Measure
+ *     Measure.new(1, 'km')
+ *     #=> #<data Measure amount=1, unit="km">
+ *
+ *
+ *  Note that member-less \Data is acceptable and might be a useful technique
+ *  for defining several homogenous data classes, like

+ *     class HTTPFetcher
+ *       Response = Data.define(:body)
+ *       NotFound = Data.define
+ *       # ... implementation

+ *  representation:
+ *
+ *      #<data HTTPFetcher::Response body="<html...">
+ *      #<data HTTPFetcher::NotFound>
+ *
+ *  And are convenient to use in pattern matching:
+ *
+ *     case fetcher.get(url)
+ *     in HTTPFetcher::Response(body)
+ *       # process body variable
+ *     in HTTPFetcher::NotFound

- *  This method is similar to strftime() function defined in ISO C and POSIX.
- *
- *  While all directives are locale independent since Ruby 1.9, %Z is platform
- *  dependent.
- *  So, the result may differ even if the same format string is used in other
- *  systems such as C.
- *
- *  %z is recommended over %Z.
- *  %Z doesn't identify the timezone.
- *  For example, "CST" is used at America/Chicago (-06:00),
- *  America/Havana (-05:00), Asia/Harbin (+08:00), Australia/Darwin (+09:30)
- *  and Australia/Adelaide (+10:30).
- *  Also, %Z is highly dependent on the operating system.
- *  For example, it may generate a non ASCII string on Japanese Windows,
- *  i.e. the result can be different to "JST".
- *  So the numeric time zone offset, %z, is recommended.
- *
- *  Examples:
- *
- *    t = Time.new(2007,11,19,8,37,48,"-06:00") #=> 2007-11-19 08:37:48 -0600
- *    t.strftime("Printed on %m/%d/%Y")         #=> "Printed on 11/19/2007"
- *    t.strftime("at %I:%M %p")                 #=> "at 08:37 AM"

-# == Timezone Argument
-#
-# A timezone argument must have +local_to_utc+ and +utc_to_local+
-# methods, and may have +name+, +abbr+, and +dst?+ methods.
-#
-# The +local_to_utc+ method should convert a Time-like object from

-# The +name+ method is used for marshaling. If this method is not
-# defined on a timezone object, Time objects using that timezone
-# object can not be dumped by Marshal.
-#
-# The +abbr+ method is used by '%Z' in #strftime.
