JRuby 1.6.0 Released

Tuesday, March 15 2011

The JRuby community is pleased to announce the release of JRuby 1.6.0.

JRuby 1.6.0 final is out!

JRuby 1.6.0 is the largest release of JRuby to date. This release fixes hundreds of user issues and brings compatibility with Ruby 1.9.2 to a very high level. We have made Windows a primary supported platform by adding it to our continuous integration environment. JRuby 1.6 will provide Windows-based Ruby users with the best experience yet. This release integrates experimental support for C extensions based on Ruby’s C API. And as with all major releases, we have improved stability and performance across the board in response to real-world user input.

Over the next month or two we plan on putting out quicker point releases in anticipation that 1.6.0 will get a new wave of feedback. Give JRuby 1.6.0 a try and let us know how things go.
