We’re pleased to announce that TruffleRuby 33.0.1 is now available. This is a bug fix release that notably adds support for structured event reporting in Rails 8.1 (and any other usage of Fiber storage). We’ve also addressed some non-UTF-8 encoding issues, Integer & Float ceil with negative precision, and mkmf.rb’s `—target-rbconfig`.
More details at:

We recommend all TruffleRuby users upgrade. Available now in common Ruby installers.
