 === Core classes compatibility issues (excluding feature bug fixes)
-
-* Array#values_at
-
-  See above.
-
-* String#lines
-* String#chars
-* String#codepoints
-* String#bytes
-
-  These methods no longer return an Enumerator, although passing a
-  block is still supported for backwards compatibility.
-
-  Code like str.lines.with_index(1) { |line, lineno| ... } no longer
-  works because str.lines returns an array.  Replace lines with
-  each_line in such cases.
-
-* IO#lines
-* IO#chars
-* IO#codepoints
-* IO#bytes
-* ARGF#lines
-* ARGF#chars
-* ARGF#bytes
-* StringIO#lines
-* StringIO#chars
-* StringIO#codepoints
-* StringIO#bytes
-* Zlib::GzipReader#lines
-* Zlib::GzipReader#bytes
-
-  These methods are deprecated in favor of each_line, each_byte,
-  each_char and each_codepoint.
-
-* Proc#==
-* Proc#eql?
-
-  These methods were removed. Two procs are == only when they are
-  the same object.
-
-* Fixnum
-* Bignum
-* Float
-
-  Fixnums, Bignums and Floats are frozen.
-
-* Signal.trap
-
-  See above.
-
-* Merge Onigmo.
-  https://github.com/k-takata/Onigmo
-
-* The :close_others option is true by default for system() and exec().
-  Also, the close-on-exec flag is set by default for all new file descriptors.
-  This means file descriptors doesn't inherit to spawned process unless
-  explicitly requested such as system(..., fd=>fd).
-
-* Kernel#respond_to? against a protected method now returns false
-  unless the second argument is true.
-
-* Kernel#respond_to_missing?
-* Kernel#initialize_clone
-* Kernel#initialize_dup
-
-  These methods are now private.
-
-* Thread#join, Thread#value
-
-  See above.
-
-* Mutex#lock, Mutex#unlock, Mutex#try_lock, Mutex#synchronize and Mutex#sleep
-
-  See above.
-
 === Stdlib updates (outstanding ones only)
-
-* cgi
-  * Add HTML5 tag maker.
-  * CGI#header has been renamed to CGI#http_header and
-    aliased to CGI#header.
-  * When HTML5 tagmaker called, overwrite CGI#header,
-    CGI#header function is to create a <header> element.
-
-* CSV
-  * Removed CSV::dump and CSV::load to protect users from dangerous
-    serialization vulnerability
-
-* iconv
-  * Iconv has been removed. Use String#encode instead.
-
-* io/console
-  * new methods:
-    * added IO#cooked which sets the terminal to cooked mode within the given block.
-    * added IO#cooked! which sets the terminal to cooked.
-  * extended method:
-    * IO#raw, IO#raw!, and IO#getch accept keyword arguments, :min and :time.
-
-* io/wait
-  * new features:
-    * added IO#wait_writable method.
-    * added IO#wait_readable method as alias of IO#wait.
-
-* json
-  * updated to 1.7.7.
-
-* net/http
-  * new features:
-    * Proxies are now automatically detected from the http_proxy environment
-      variable.  See Net::HTTP::new for details.
-    * gzip and deflate compression are now requested for all requests by
-      default.  See Net::HTTP for details.
-    * SSL sessions are now reused across connections for a single instance.
-      This speeds up connection by using a previously negotiated session.
-    * Requests may be created from a URI which sets the request_uri and host
-      header of the request (but does not change the host connected to).
-    * Responses contain the URI requested which allows easier implementation of
-      redirect following.
-  * new methods:
-    * Net::HTTP#local_host
-    * Net::HTTP#local_host=
-    * Net::HTTP#local_port
-    * Net::HTTP#local_port=
-  * extended method:
-    * Net::HTTP#connect uses local_host and local_port if specified.
-
-* net/imap
-  * new methods:
-    * Net::IMAP.default_port
-    * Net::IMAP.default_imap_port
-    * Net::IMAP.default_tls_port
-    * Net::IMAP.default_ssl_port
-    * Net::IMAP.default_imaps_port
-
-* objspace
-  * new method:
-    * ObjectSpace.reachable_objects_from(obj)
-
-* openssl
-  * Consistently raise an error when trying to encode nil values. All instances
-    of OpenSSL::ASN1::Primitive now raise TypeError when calling to_der on an
-    instance whose value is nil. All instances of OpenSSL::ASN1::Constructive
-    raise NoMethodError in the same case. Constructing such values is still
-    permitted.
-  * TLS 1.1 & 1.2 support by setting OpenSSL::SSL::SSLContext#ssl_version to
-    :TLSv1_2, :TLSv1_2_server, :TLSv1_2_client or :TLSv1_1, :TLSv1_1_server
-    :TLSv1_1_client. The version being effectively used can be queried
-    with OpenSSL::SSL#ssl_version. Furthermore, it is also possible to
-    blacklist the new TLS versions with OpenSSL::SSL:OP_NO_TLSv1_1 and
-    OpenSSL::SSL::OP_NO_TLSv1_2.
-  * Added OpenSSL::SSL::SSLContext#renegotiation_cb. A user-defined callback
-    may be set which gets called whenever a new handshake is negotiated. This
-    also allows to programmatically decline (client) renegotiation attempts.
-  * Support for "0/n" splitting of records as BEAST mitigation via
-    OpenSSL::SSL::OP_DONT_INSERT_EMPTY_FRAGMENTS.
-  * The default options for OpenSSL::SSL::SSLContext have changed to
-    OpenSSL::SSL::OP_ALL & ~OpenSSL::SSL::OP_DONT_INSERT_EMPTY_FRAGMENTS
-    instead of OpenSSL::SSL::OP_ALL only. This enables the countermeasure for
-    the BEAST attack by default.
-  * OpenSSL requires passwords for decrypting PEM-encoded files to be at least
-    four characters long. This led to awkward situations where an export with
-    a password with fewer than four characters was possible, but accessing the
-    file afterwards failed. OpenSSL::PKey::RSA, OpenSSL::PKey::DSA and
-    OpenSSL::PKey::EC therefore now enforce the same check when exporting a
-    private key to PEM with a password - it has to be at least four characters
-    long.
-  * SSL/TLS support for the Next Protocol Negotiation extension. Supported
-    with OpenSSL 1.0.1 and higher.
-  * OpenSSL::OPENSSL_FIPS allows client applications to detect whether OpenSSL
-    is FIPS-enabled. OpenSSL.fips_mode= allows turning on and off FIPS mode
-    manually in order to adapt to situations where FIPS mode would be an
-    explicit requirement.
-  * Authenticated Encryption with Associated Data (AEAD) is supported via
-    Cipher#auth_data= and Cipher#auth_tag/Cipher#auth_tag=.
-    Currently (OpenSSL 1.0.1c), only GCM mode is supported.
-
-* ostruct
-  * new methods:
-    * OpenStruct#[], []=
-    * OpenStruct#each_pair
-    * OpenStruct#eql?
-    * OpenStruct#hash
-    * OpenStruct#to_h converts the struct to a hash.
-  * extended method:
-    * OpenStruct.new also accepts an OpenStruct / Struct.
-
-* pathname
-  * extended method:
-    * Pathname#find returns an enumerator if no block is given.
-
-* rake
-  * rake has been updated to version 0.9.5.
-
-    This version is backwards-compatible with previous rake versions and
-    contains many bug fixes.
-
-    See
-    http://rake.rubyforge.org/doc/release_notes/rake-0_9_5_rdoc.html for a list
-    of changes in rake 0.9.3, 0.9.4 and 0.9.5.
-
-* RDoc
-  * RDoc has been updated to version 4.0
-
-    This version is largely backwards-compatible with previous rdoc versions.
-    The most notable change is an update to the ri data format (ri data must
-    be regenerated for gems shared across rdoc versions).  Further API changes
-    are internal and won't affect most users.
-
-    Notable changes include:
-
-    * Page support for ri.  Try `ri ruby:` for a list of pages in ruby or
-      `ri ruby:syntax/literals` for the syntax documentation for literals.
-
-      This also works for gems such as `ri rspec:README` for the rspec gem's
-      README file.
-    * Markdown support.  See ri RDoc::Markdown for details.
-
-    See https://github.com/rdoc/rdoc/blob/master/History.rdoc for a full list
-    of changes in rdoc 4.0.
-
-* resolv
-  * new methods:
-    * Resolv::DNS#timeouts=
-    * Resolv::DNS::Config#timeouts=
-
-* rexml
-  * REXML::Document#write supports Hash arguments.
-  * REXML::Document#write supports new :encoding option. It changes
-    XML document encoding. Without :encoding option, encoding in
-    XML declaration is used for XML document encoding.
-
-* RubyGems
-  * Updated to 2.0.0
-
-    RubyGems 2.0.0 features the following improvements:
-
-    * Improved support for default gems shipping with ruby 2.0.0+
-    * A gem can have arbitrary metadata through Gem::Specification#metadata
-    * `gem search` now defaults to --remote and is anchored like gem list.
-    * Added --document to replace --rdoc and --ri.  Use --no-document to
-      disable documentation, --document=rdoc to only generate rdoc.
-    * Only ri-format documentation is generated by default.
-    * `gem server` uses RDoc::Servlet from RDoc 4.0 to generate HTML
-      documentation.
-
-    For an expanded list of updates and bug fixes see:
-    https://github.com/rubygems/rubygems/blob/master/History.txt
-
-* shellwords
-  * Shellwords#shellescape now stringifies the given object using to_s.
-  * Shellwords#shelljoin accepts non-string objects in the given
-    array, each of which is stringified using to_s.
-
-* stringio
-  * deprecated methods:
-    * StringIO#lines, #bytes, #chars and #codepoints are deprecated.
-
-* syslog
-  * Added Syslog::Logger which provides a Logger API atop Syslog.
-  * Syslog::Priority, Syslog::Level, Syslog::Option and Syslog::Macros
-    are introduced for easy detection of available constants on a
-    running system.
-
-* tmpdir
-  * incompatible changes:
-    * Dir.mktmpdir uses FileUtils.remove_entry instead of
-      FileUtils.remove_entry_secure.  This means that applications should not
-      change the permission of the created temporary directory to make
-      accessible from other users.
-
-* yaml
-  * Syck has been removed.  YAML now completely depends on libyaml being
-    installed.
-  * libyaml is now bundled with ruby, for cases where the library is not
-    installed locally.
-
-* zlib
-  * Added streaming support for Zlib::Inflate and Zlib::Deflate.  This allows
-    processing of a stream without the use of large amounts of memory.
-  * Added support for the new deflate strategies Zlib::RLE and Zlib::FIXED.
-  * Zlib streams are now processed without the GVL.  This allows gzip, zlib and
-    deflate streams to be processed in parallel.
-  * deprecated methods:
-    * Zlib::GzipReader#lines and #bytes are deprecated.
-
 === Stdlib compatibility issues (excluding feature bug fixes)
-
-* OpenStruct new methods can conflict with custom attributes named
-  "each_pair", "eql?", "hash" or "to_h".
-
-* Dir.mktmpdir in lib/tmpdir.rb
-
-  See above.
-
 === C API updates
-
-* NUM2SHORT() and NUM2USHORT() added. They are similar to NUM2INT, but short.
-
-* rb_newobj_of() and NEWOBJ_OF() added. They create a new object of a given class.
-
