• Array#fetch_values was added. [[Feature #20702]]
• Exception#set_backtrace now accepts arrays of Thread::Backtrace::Location. Kernel#raise, Thread#raise and Fiber#raise also accept this new format. [[Feature #13557]]
• An optional Fiber::Scheduler#blocking_operation_wait hook allows blocking operations to be moved out of the
  event loop in order to reduce latency and improve multi-core processor utilization. [[Feature #20876]]
• GC.config added to allow setting configuration variables on the Garbage Collector. [[Feature #20443]]
• GC configuration parameter rgengc_allow_full_mark introduced. When false GC will only mark young objects. Default is true. [[Feature #20443]]
• Hash.new now accepts an optional capacity: argument, to preallocate the hash with a given capacity.
  This can improve performance when building large hashes incrementally by saving on reallocation and
  rehashing of keys. [[Feature #19236]]
• IO::Buffer#copy can release the GVL, allowing other threads to run while copying data. [[Feature #20902]]
• Integer#** used to return Float::INFINITY when the return value is large, but now returns an Integer.
  If the return value is extremely large, it raises an exception.
  [[Feature #20811]]
• MatchData#bytebegin and MatchData#byteend have been added. [[Feature #20576]]
• require in Ractor is allowed. The requiring process will be run on
  the main Ractor.
  Ractor._require(feature) is added to run requiring process on the
  main Ractor.
  [[Feature #20627]]
• Ractor.main? is added. [[Feature #20627]]
• Ractor.[] and Ractor.[]= are added to access the ractor local storage
  of the current Ractor. [[Feature #20715]]
• Ractor.store_if_absent(key){ init } is added to initialize ractor local
  variables in thread-safty. [[Feature #20875]]
• Range#size now raises TypeError if the range is not iterable. [[Misc #18984]]
• Range#step now consistently has a semantics of iterating by using + operator
  for all types, not only numerics. [[Feature #18368]]
• Rational#** used to return Float::INFINITY or Float::NAN
  when the numerator of the return value is large, but now returns an Integer.
  If it is extremely large, it raises an exception. [[Feature #20811]]
• Add RubyVM::AbstractSyntaxTree::Node#locations method which returns location objects
  associated with the AST node. [[Feature #20624]]
• Add RubyVM::AbstractSyntaxTree::Location class which holds location information. [[Feature #20624]]
• String#append_as_bytes was added to more easily and efficiently work with binary buffers and protocols.
  It directly concatenate the arguments into the string without any encoding validation or conversion.
  [[Feature #20594]]
• The string returned by Symbol#to_s now emits a deprecation warning when mutated, and will be
  frozen in a future version of Ruby.
  These warnings can be enabled with -W:deprecated or by setting Warning[:deprecated] = true.
  [[Feature #20350]]
• On Windows, now Time#zone encodes the system timezone name in UTF-8
  instead of the active code page, if it contains non-ASCII characters.
  [[Bug #20929]]
• Time#xmlschema, and its Time#iso8601 alias have been moved into the core Time
  class while previously it was an extension provided by the time gem. [[Feature #20707]]
• Add Warning.categories method which returns a list of possible warning categories.
  [[Feature #20293]]
• The keyword argument anonymous: true is implemented for Tempfile.create.
  Tempfile.create(anonymous: true) removes the created temporary file immediately.
  So applications don't need to remove the file.
  [[Feature #20497]]
• Refinement#refined_class has been removed. [[Feature #19714]]
• DidYouMean::SPELL_CHECKERS[]= and DidYouMean::SPELL_CHECKERS.merge! are removed.
• Removed the following deprecated constants:
  * Net::HTTP::ProxyMod
  * Net::NetPrivate::HTTPRequest
  * Net::HTTPInformationCode
  * Net::HTTPSuccessCode
  * Net::HTTPRedirectionCode
  * Net::HTTPRetriableCode
  * Net::HTTPClientErrorCode
  * Net::HTTPFatalErrorCode
  * Net::HTTPServerErrorCode
  * Net::HTTPResponseReceiver
  * Net::HTTPResponceReceiver
