What if Ruby 4.0 features could be implemented in pure Ruby?
With TruffleRuby, that’s possible: 73% of the core library is written in Ruby itself.
We currently have 10 issues tagged [easy, pure Ruby] waiting for contributors: github.com/truffleruby/truff…

This release addresses several performance issues detected while getting a large Rails app running on TruffleRuby at Shopify. I’ll write up a blog post with more details soon-ish. In the meanwhile, please give it a try. It should run Rails applications quite well.
TruffleRuby 24.1 is released!🚀🎉 It updates to Ruby 3.2.4, gets a lot of compatibility and bug fixes, and significant performance improvements: github.com/oracle/trufflerub…
Available via ruby-install/ruby-build/rbenv/asdf/rvm/setup-ruby as usual.

Available via ruby-install/ruby-build/rbenv/asdf/rvm/setup-ruby as usual.
The main performance improvement is a complete review of all 100+ inline caches to ensure they use splitting to keep these inline caches as fast and monomoprhic as possible. You can find more information about splitting and inline caches in this talk: rubykaigi.org/2023/presentat…
