Constants and class variables resolve through the + original class, consistent with inheritance and mixins. + [[Feature #21981]] + +## Core classes updates + +Note: We're only listing outstanding class updates. + +* Array + + * `Array#pack` accepts a new format `R` and `r` for unpacking unsigned + and signed LEB128 encoded integers. [[Feature #21785]] + * `Array#pack` accepts a new format `^` that returns the current offset. + Useful when combined with variable width formats like LEB128. [[Feature #21796]] + +* ENV + + * `ENV.fetch_values` is added. It returns an array of values for the + given names, raising `KeyError` for missing names unless a block is + given. [[Feature #21781]] + +* Kernel + + * `Kernel#autoload_relative` and `Module#autoload_relative` are added. + These methods work like `autoload`, but resolve the file path relative + to the file where the method is called, similar to `require_relative`. + This makes it easier to autoload constants from files in the same + directory without hardcoding absolute paths or manipulating `$LOAD_PATH`. + [[Feature #15330]] + +* MatchData + + * `MatchData#integer_at` is added. It converts the matched substring to + integer and return the result. [[Feature #21932]] + +* Regexp + + * All instances of `Regexp` are now frozen, not just literals. + Subclasses of `Regexp` are not frozen for compatibility. + [[Feature #8948]] + +* Set + + * A deprecated behavior, `Set#to_set`, `Range#to_set`, and + `Enumerable#to_set` accepting arguments, was removed. [[Feature #21390]] + +## Stdlib updates + +### The following bundled gems are added. + + +We only list stdlib changes that are notable feature changes. + +Other changes are listed in the following sections. We also listed release +history from the previous bundled version that is Ruby 3.4.0 if it has GitHub +releases. + +### The following bundled gems are promoted from default gems. + +* tsort 0.2.0 +* win32-registry 0.1.2 + +### The following default gem is added. + +### The following default gems are updated. + +* RubyGems 4.1.0.dev + * 4.0.3 to [v4.0.4][RubyGems-v4.0.4], [v4.0.5][RubyGems-v4.0.5], [v4.0.6][RubyGems-v4.0.6], [v4.0.7][RubyGems-v4.0.7], [v4.0.8][RubyGems-v4.0.8], [v4.0.9][RubyGems-v4.0.9], [v4.0.10][RubyGems-v4.0.10], [v4.0.11][RubyGems-v4.0.11], [v4.0.12][RubyGems-v4.0.12], [v4.0.13][RubyGems-v4.0.13] +* bundler 4.1.0.dev + * 4.0.3 to [v4.0.4][bundler-v4.0.4], [v4.0.5][bundler-v4.0.5], [v4.0.6][bundler-v4.0.6], [v4.0.7][bundler-v4.0.7], [v4.0.8][bundler-v4.0.8], [v4.0.9][bundler-v4.0.9], [v4.0.10][bundler-v4.0.10], [v4.0.11][bundler-v4.0.11], [v4.0.12][bundler-v4.0.12], [v4.0.13][bundler-v4.0.13] +* erb 6.0.4 + * 6.0.1 to [v6.0.1.1][erb-v6.0.1.1], [v6.0.2][erb-v6.0.2], [v6.0.3][erb-v6.0.3], [v6.0.4][erb-v6.0.4] +* ipaddr 1.2.9 + * 1.2.8 to [v1.2.9][ipaddr-v1.2.9] +* json 2.19.8 + * 2.18.0 to [v2.18.1][json-v2.18.1], [v2.19.0][json-v2.19.0], [v2.19.1][json-v2.19.1], [v2.19.2][json-v2.19.2], [v2.19.3][json-v2.19.3], [v2.19.4][json-v2.19.4], [v2.19.5][json-v2.19.5], [v2.19.6][json-v2.19.6], [v2.19.7][json-v2.19.7] +* openssl 4.0.2 + * 4.0.0 to [v4.0.1][openssl-v4.0.1], [v4.0.2][openssl-v4.0.2] +* prism 1.9.0 + * 1.7.0 to [v1.8.0][prism-v1.8.0], [v1.8.1][prism-v1.8.1], [v1.9.0][prism-v1.9.0] +* psych 5.4.0 +* resolv 0.7.1 + * 0.7.0 to [v0.7.1][resolv-v0.7.1] +* stringio 3.2.1.dev +* strscan 3.1.9.dev + * 3.1.6 to [v3.1.7][strscan-v3.1.7], [v3.1.8][strscan-v3.1.8] +* syntax_suggest 3.0.0 +* timeout 0.6.1 + * 0.6.0 to [v0.6.1][timeout-v0.6.1] +* zlib 3.2.3 + * 3.2.2 to [v3.2.3][zlib-v3.2.3] + +### The following bundled gems are updated. + +* minitest 6.0.6 +* rake 13.4.2 + * 13.3.1 to [v13.4.0][rake-v13.4.0], [v13.4.1][rake-v13.4.1], [v13.4.2][rake-v13.4.2] +* test-unit 3.7.7 + * 3.7.5 to [3.7.6][test-unit-3.7.6], [3.7.7][test-unit-3.7.7] +* net-imap 0.6.4 + * 0.6.2 to [v0.6.3][net-imap-v0.6.3], [v0.6.4][net-imap-v0.6.4] +* rbs 4.0.2 + * 3.10.0 to [v3.10.1][rbs-v3.10.1], [v3.10.2][rbs-v3.10.2], [v3.10.3][rbs-v3.10.3], [v3.10.4][rbs-v3.10.4], [v4.0.0.dev.5][rbs-v4.0.0.dev.5], [v4.0.0][rbs-v4.0.0], [v4.0.2][rbs-v4.0.2] +* typeprof 0.32.0 +* mutex_m 0.3.0 +* bigdecimal 4.1.2 + * 4.0.1 to [v4.1.0][bigdecimal-v4.1.0], [v4.1.1][bigdecimal-v4.1.1], [v4.1.2][bigdecimal-v4.1.2] +* resolv-replace 0.2.0 + * 0.1.1 to [v0.2.0][resolv-replace-v0.2.0] +* syslog 0.4.0 + * 0.3.0 to [v0.4.0][syslog-v0.4.0] +* repl_type_completor 0.1.15 + * 0.1.12 to [v0.1.13][repl_type_completor-v0.1.13], [v0.1.14][repl_type_completor-v0.1.14], [v0.1.15][repl_type_completor-v0.1.15] +* pstore 0.2.1 + * 0.2.0 to [v0.2.1][pstore-v0.2.1] +* rdoc 7.2.0 + * 7.0.3 to [v7.0.4][rdoc-v7.0.4], [v7.1.0][rdoc-v7.1.0], [v7.2.0][rdoc-v7.2.0] +* win32ole 1.9.3 + * 1.9.2 to [v1.9.3][win32ole-v1.9.3] +* irb 1.18.0 + * 1.16.0 to [v1.17.0][irb-v1.17.0], [v1.18.0][irb-v1.18.0] + +### RubyGems and Bundler + +Ruby 4.0 bundled RubyGems and Bundler version 4. see the following links for details. + +## Supported platforms + +## Compatibility issues + +## Stdlib compatibility issues + +## C API updates + +### Embedded TypedData + +* The `RUBY_TYPED_EMBEDDABLE` flag is now public and documented and can be used by C extensions. + It allows allocating C structs directly into Ruby object slots, which reduces pointer chasing, + and in some case memory usage. + See the C extension documentation for details.
