Ruby 3.1 was released on 25 December 2021.<ref name="Ruby 3.1.0 Released" /> It includes YJIT, a new, experimental, Just-In-Time Compiler developed by [[Shopify]], to enhance the performance of real world business applications. A new [[debugger]] is also included. There are some syntax enhancements and other improvements in this release. Network libraries for [[FTP]], [[SMTP]], [[IMAP]], and [[Post Office Protocol|POP]] are moved from default gems to bundled gems.<ref>{{cite web|url=https://www.ruby-lang.org/en/news/2021/12/25/ruby-3-1-0-released//|title=Ruby 3.1.0 Released|access-date=2021-12-26|archive-date=2021-12-26|archive-url=https://web.archive.org/web/20211226065055/https://www.ruby-lang.org/en/news/2021/12/25/ruby-3-1-0-released//|url-status=live}}</ref>

Ruby 3.2 was released on 25 December 2022.<ref name="Ruby 3.2.0 Released">{{Cite web|url=https://www.ruby-lang.org/en/news/2022/12/25/ruby-3-2-0-released/|title=Ruby 3.2.0 Released|access-date=2022-12-25|archive-date=2022-12-25|archive-url=https://web.archive.org/web/20221225084459/https://www.ruby-lang.org/en/news/2022/12/25/ruby-3-2-0-released/|url-status=live}}</ref> It brings support for being run inside of a [[WebAssembly]] environment via a WASI interface. [[Regular expression]]s also receives some improvements, including a faster, [[Memoizationmemoization|memoized]] matching algorithm to protect against certain [[ReDoS]] attacks, and configurable timeouts for regular expression matching. Additional debugging and syntax features are also included in this release, which include syntax suggestion, as well as error highlighting. The MJIT compiler has been re-implemented as a standard library module, while the YJIT, a [[Rust (programming language)|Rust]]-based [[Just-in-time compilation|JIT]] compiler now supports more architectures on Linux.

Ruby 3.3 was released on 25 December 2023.<ref name="Ruby 3.3.0 Released">{{Cite web|url=https://www.ruby-lang.org/en/news/2023/12/25/ruby-3-3-0-released/|title=Ruby 3.3.0 Released|access-date=2023-12-25|archive-date=2023-12-25|archive-url=https://web.archive.org/web/20231225071449/https://www.ruby-lang.org/en/news/2023/12/25/ruby-3-3-0-released/|url-status=live}}</ref> Ruby 3.3 introduces significant enhancements and performance improvements to the language. Key features include the introduction of the Prism parser for portable and maintainable parsing, the addition of the pure-Ruby JIT compiler RJIT, and major performance boosts in the YJIT compiler. Additionally, improvements in memory usage, the introduction of an M:N thread scheduler, and updates to the standard library contribute to a more efficient and developer-friendly Ruby ecosystem.

Line 208:

* Cardinal, an implementation for the [[Parrot virtual machine]]

* [[Ruby Enterprise Edition]], often shortened to ''ree'', an implementation optimized to handle large-scale [[Ruby on Rails]] projects

* [[HotRuby]], a [[JavaScript]] and [[ActionScript]] implementation of the [[Ruby programming language]]

The maturity of Ruby implementations tends to be measured by their ability to run the [[Ruby on Rails]] (Rails) framework, because it is complex to implement and uses many Ruby-specific features. The point when a particular implementation achieves this goal is called "the Rails singularity". The reference implementation, JRuby, and Rubinius<ref name="Rubinius"/> are all able to run Rails unmodified in a production environment.
