[[Feature #20564]] + +## Modular GC + +* Alternative garbage collector (GC) implementations can be loaded dynamically + through the modular garbage collector feature. To enable this feature, + configure Ruby with `--with-modular-gc` at build time. GC libraries can be + loaded at runtime using the environment variable `RUBY_GC_LIBRARY`. + [[Feature #20351]] + +* Ruby's built-in garbage collector has been split into a separate file at + `gc/default/default.c` and interacts with Ruby using an API defined in + `gc/gc_impl.h`. The built-in garbage collector can now also be built as a + library using `make modular-gc MODULAR_GC=default` and enabled using the + environment variable `RUBY_GC_LIBRARY=default`. [[Feature #20470]] + +* An experimental GC library is provided based on [MMTk](https://www.mmtk.io/). + This GC library can be built using `make modular-gc MODULAR_GC=mmtk` and + enabled using the environment variable `RUBY_GC_LIBRARY=mmtk`. This requires + the Rust toolchain on the build machine. [[Feature #20860]] + + +## Language changes + +* String literals in files without a `frozen_string_literal` comment now behave + as if they were frozen. If they are mutated a deprecation warning is emitted. + These warnings can be enabled with `-W:deprecated` or by setting `Warning[:deprecated] = true`. + To disable this change, you can run Ruby with the `--disable-frozen-string-literal` + command line argument. [[Feature #20205]] + +* `it` is added to reference a block parameter. [[Feature #18980]] + +* Keyword splatting `nil` when calling methods is now supported. + `**nil` is treated similarly to `**{}`, passing no keywords, + and not calling any conversion methods. [[Bug #20064]] + +* Block passing is no longer allowed in index. [[Bug #19918]] + +* Keyword arguments are no longer allowed in index. [[Bug #20218]] + +## YJIT + +TL;DR: +* Better performance on most benchmarks on both x86-64 and arm64 platforms. +* Reduced memory usage of compilation metadata +* Multiple bug fixes. YJIT is now even more robust and better tested. + +New features: +* Add unified memory limit via `--yjit-mem-size` command-line option (default 128MiB) + which tracks total YJIT memory usage and is more intuitive than the + old `--yjit-exec-mem-size`. +* More statistics now always available via `RubyVM::YJIT.runtime_stats` +* Add compilation log to track what gets compiled via `--yjit-log` + * Tail of the log also available at run-time via `RubyVM::YJIT.log` +* Add support for shareable consts in multi-ractor mode +* Can now trace counted exits with `--yjit-trace-exits=COUNTER` + +New optimizations: +* Compressed context reduces memory needed to store YJIT metadata +* Improved allocator with ability to allocate registers for local variables +* When YJIT is enabled, use more Core primitives written in Ruby: + * `Array#each`, `Array#select`, `Array#map` rewritten in Ruby for better performance [[Feature #20182]]. +* Ability to inline small/trivial methods such as: + * Empty methods + * Methods returning a constant + * Methods returning `self` + * Methods directly returning an argument +* Specialized codegen for many more runtime methods +* Optimize `String#getbyte`, `String#setbyte` and other string methods +* Optimize bitwise operations to speed up low-level bit/byte manipulation +* Various other incremental optimizations + +## Core classes updates + +Note: We're only listing outstanding class updates. + +* Exception + + * `Exception#set_backtrace` now accepts an array of `Thread::Backtrace::Location`. + `Kernel#raise`, `Thread#raise` and `Fiber#raise` also accept this new format. [[Feature #13557]] + +* Range + + * `Range#size` now raises `TypeError` if the range is not iterable. [[Misc #18984]] + + + +## Compatibility issues + +Note: Excluding feature bug fixes. + +* Error messages and backtrace displays have been changed. + * Use a single quote instead of a backtick as a opening quote. [[Feature #16495]] + * Display a class name before a method name (only when the class has a permanent name). [[Feature #19117]] + * `Kernel#caller`, `Thread::Backtrace::Location`'s methods, etc. are also changed accordingly. + + ``` + Old: + test.rb:1:in `foo': undefined method `time' for an instance of Integer + from test.rb:2:in `
