{% assign release = site.data.releases | where: "version", "3.3.0-preview1" | first %}
11+
12+
We are pleased to announce the release of Ruby {{ release.version }}. Ruby 3.3 adds a new pure-Ruby JIT compiler named RJIT, uses lrama as a parser generator, and many performance improvements especially YJIT.
13+
14+
## RJIT
15+
16+
* Introduced a pure-Ruby JIT compiler RJIT and replaced MJIT.
17+
* RJIT supports only x86\_64 architecture on Unix platforms.
18+
* Unlike MJIT, it doesn't require a C compiler at runtime.
19+
* RJIT exists only for experimental purposes.
20+
* You should keep using YJIT in production.
21+
* If you are interested in developing JIT for Ruby, please check out [k0kubun's presentation on Day 3 of RubyKaigi](https://rubykaigi.org/2023/presentations/k0kubun.html#day3).
22+
23+
## Use Lrama instead of Bison
24+
25+
* Replace Bison with [Lrama LALR parser generator](https://github.com/yui-knk/lrama) [Feature #19637]
26+
* If you have interest, please see [The future vision of Ruby Parser](https://rubykaigi.org/2023/presentations/spikeolaf.html)
27+
28+
## YJIT
29+
30+
* Significant performance improvements over 3.2
31+
* Splat and rest arguments support has been improved.
32+
* Registers are allocated for stack operations of the virtual machine.
33+
* More calls with optional arguments are compiled.
34+
* `Integer#!=`, `String#!=`, `Kernel#block_given?`, `Kernel#is_a?`,
35+
`Kernel#instance_of?`, `Module#===` are specially optimized.
36+
* Instance variables no longer exit to the interpreter
37+
with megamorphic Object Shapes.
38+
* Metadata for compiled code uses a lot less memory.
39+
* Improved code generation on ARM64
40+
* Option to start YJIT in paused mode and then later enable it manually
41+
* `--yjit-pause` and `RubyVM::YJIT.resume`
42+
* This can be used to enable YJIT only once your application is done booting
43+
* Exit tracing option now supports sampling
44+
* `--trace-exits-sample-rate=N`
45+
* Multiple bug fixes
46+
47+
48+
49+
## Other Notable New Features
50+
51+
### Language
52+
53+
54+
55+
## Performance improvements
56+
57+
* `defined?(@ivar)` is optimized with Object Shapes.
58+
59+
## Other notable changes since 3.2
60+
61+
62+
63+
## Compatibility issues
64+
65+
Note: Excluding feature bug fixes.
66+
67+
### Removed constants
68+
69+
The following deprecated constants are removed.
70+
71+
72+
73+
### Removed methods
74+
75+
The following deprecated methods are removed.
76+
77+
78+
79+
## Stdlib compatibility issues
80+
81+
### `ext/readline` is retired
82+
83+
* We have `reline` that is pure Ruby implementation compatible with `ext/readline` API. We rely on `reline` in the future. If you need to use `ext/readline`, you can install `ext/readline` via rubygems.org with `gem install readline-ext`.
84+
* We no longer need to install libraries like `libreadline` or `libedit`.
85+
86+
## C API updates

## What is Ruby
166+
167+
Ruby was first developed by Matz (Yukihiro Matsumoto) in 1993,
168+
and is now developed as Open Source. It runs on multiple platforms
169+
and is used all over the world especially for web development.
