Title: Ruby 3.3.0-preview2 Released
Summary: We are pleased to announce the release of Ruby 3.3.0-preview2. Ruby 3.3 adds a new pure-Ruby JIT compiler named RJIT, uses Lrama as a parser generator, and many performance improvements especially YJIT.

RJIT


  Introduced a pure-Ruby JIT compiler RJIT and replaced MJIT.
    
      RJIT supports only x86_64 architecture on Unix platforms.
      Unlike MJIT, it doesn’t require a C compiler at runtime.
    
  
  RJIT exists only for experimental purposes.
    
      You should keep using YJIT in production.
    
  
  If you are interested in developing JIT for Ruby, please check out k0kubun’s presentation on Day 3 of RubyKaigi.


Use Lrama instead of Bison


  Replace Bison with Lrama LALR parser generator Feature #19637
    
      If you have interest, please see The future vision of Ruby Parser
    
  


YJIT


  Major performance improvements over 3.2
    
      Support for splat and rest arguments has been improved.
      Registers are allocated for stack operations of the virtual machine.
      More calls with optional arguments are compiled.
      Exception handlers are also compiled.
      Instance variables no longer exit to the interpreter
with megamorphic Object Shapes.
      Unsupported call types no longer exit to the interpreter.
      Integer#!=, String#!=, Kernel#block_given?, Kernel#is_a?,
Kernel#instance_of?, Module#=== are specially optimized.
      Now more than 3x faster than the interpreter on optcarrot!
    
  
  Metadata for compiled code uses a lot less memory.
  Generate more compact code on ARM64
  Option to start YJIT in paused mode and then later enable it manually
    
      --yjit-pause and RubyVM::YJIT.resume
      This can be used to enable YJIT only once your application is done booting
    
  
  ratio_in_yjit stat produced by --yjit-stats is now available in release builds,
a special stats or dev build is no longer required.
  Exit tracing option now supports sampling
    
      --trace-exits-sample-rate=N
    
  
  More thorough testing and multiple bug fixes


Other Notable New Features

IRB has received several enhancements, including but not limited to:


  Advanced irb:rdbg integration that provides an equivalent debugging experience to pry-byebug (doc).
  Pager support for commands like ls and show_cmds.
  More accurate and helpful information provided by the ls and show_source commands.


In addition, IRB has also undergone extensive refactoring and received dozens of bug fixes to facilitate easier future enhancements.
