I am giving a talk next week (Weds 12:15-12:45) at RubyConf on implementing an esoteric programming langage in Ruby. This talk will describe the language and then delve into how I optimize the language to make it run faster and faster. #rubyconf

I am going to be testing out blue sky to see how it feels. I am enebō.bsky.social if you are on there.

We have released jar-dependencies 0.5.2, now that JRuby 9.4.10.0 can safely handle upgrading it independent of JRuby itself. This finally fixes issues sourcing jar dependencies from Maven in containerized environments (previously partially fixed by updating ruby-maven-libs).

JRuby 9.4.12.0 has been released with two important fixes: a thread-safety patch for recent Class#subclasses logic and an update for jar-dependencies to fix issues parsing Maven output on Java 9+. Let us know if you run into any new issues! buff.ly/4hQOCSh

We have just released JRuby 10.0.1.0, our first update to JRuby 10! There's dozens of patches including full support (finally) for Zeitwerk and a bunch of Ruby 3.4 language fixes. Upgrade today and let us know how it goes! jruby.org/2025/07/17/jru…

JRuby 10.0.2.0 is released! This is a small release to fix an ArgumentError regression in JRuby 10.0.1.0 plus a few other small fixes. Recommended upgrade for all, but let us know if you run into any issues! jruby.org/2025/08/07/jru…
