In about an hour I'll do my first solo JRuby workshop at RubyConf Austria! I've used this opportunity to start assembling a complete JRuby tutorial, and I'd love to include your ideas.

In addition to sponsoring #RubyKaigi2026 , our CTO, @headius, delivered the second-day keynote: "Twenty Years of JRuby".
What a great look back on the history of JRuby... and a look toward the future with the official announcement of the release of JRuby 10.1!

We're still working on updating our conference page at the new https://t.co/Hj9EMW184c , but we did get the incredible honor of being a sponsor for #RubyKaigi last month! More posts on our current and upcoming conferences soon!

It was an honor to attend and have our CTO, @headius speak at the inaugural @rbqconf in Austin, Texas!

Charles spoke about the latest @JRuby developments, showing a whole bunch of features that make JRuby the only choice for big businesses. Half the room had already used JRuby!

JRuby 10.0.5.0 is released! This round we fixed some memory leaks when embedding multiple JRuby instances, a few pesky Windows bugs, and several Ruby compatibility blockers. Enjoy!

I am excited and honored to be the keynote speaker for day 2 of #RubyKaigi 2026! My talk will explore 20 years of JRuby development, show how JRuby and CRuby have grown up together, and provide a hopeful look forward to the future of Ruby. It's been an amazing ride! 🤩

The Headius team will be at RBQ next week - will we see you there?

[Charles Oliver Nutter @headius]

Starting to look like we need an informal JRuby meetup in Austin for RBQ! I'll have a chat with the the decision makers and try to put something together. Let me know if you'll be there and interested!

[JRuby Dev Team @jruby]

JRuby 10.0.4.0 is released! A month after 10.0.3.0, we've addressed lots of one-off issues, a few memory and thread-safety fixes, and general compatibility and stabilization work. Enjoy!

JRuby 10.1 with Ruby 4.0 support is now on master and it's GREEN! 10.1 snapshots have been pushed for Maven and as "jruby-head" for Ruby installers and the setup-ruby GHA action. Docker Hub dev images will be available soon. Get in there and test it out!

[Charles Oliver Nutter @headius]

JRuby's support for Ruby 4.0 has been merged, only 2 months after the CRuby release! Just a handful of tests were excluded... 99% of 4.0 features are ready for JRuby 10.1. I'll spend the next few weeks on optimization experiments and stabilization.

[Charles Oliver Nutter @headius]

I am honored to be a keynote speaker at RubyKaigi 2026! Looking forward to meeting more of the Ruby world in Hakodate and finding new ways to support the Ruby community.

[Charles Oliver Nutter @headius]

Looks like a great lineup of speakers and also me! I'm thrilled to visit Wroclaw and speak at https://t.co/YvDRA3PxxU for the first time. Back to back with Ruby Kaigi so it's going to be an interesting trip!

[Charles Oliver Nutter @headius]

Just a few weeks left until RBQ Conf in Austin! My first trip back since Keep Ruby Weird in 2016. Looking forward to catching up with the local community and showing the latest and greatest JRuby use cases! Here's a discount code for https://t.co/VXIND8rgtu : ShareTheRBQ

New year, new logo! Watch for our new logo "Maximus" at a conference in 2026!

[JRuby Dev Team @jruby]

JRuby 10.0.3.0 is released! Over 80 issues and pull requests and 13 external contributors combined to help further stabilize our 10.0 series! There's lots of compatibility fixes, a few performance enhancements, and a number of library updates.

[Charles Oliver Nutter @headius]

JRuby 10.1 is just a few dozen tests away from being Ruby 4.0 compatible. We should be able to release in the next few weeks. Feels good to stay caught up and get our recent performance work out to users along with up-to-date compatibility!
