JRuby 1.6 Released: Ruby 1.9.2 Support and More

By Peter Cooper / March 15, 2011

It's a newsflash! JRuby 1.6.0 has been released today. Congratulations to the JRuby team. 1.6 is a significant and much awaited release and comes after a 9 month push of over 2500 commits.

Hit up the official release post for the full run-through but here are some of the highlights of the release:

  • Windows has been added to the JRuby team's continuous integration system meaning that Windows support is only going to get better
  • Ruby 1.9.2 language and API support (with the exception of Encoding::Converter and ripper)
  • Built in profiler
  • General performance improvements
  • Experimental support for C extensions (with provisos)
  • RSpec is no longer included (worth mentioning in case it catches you out..)

You can download binary and source releases direct from if you want to get up to date or update RVM with rvm get head and rvm reload before running rvm install jruby-1.6.0 :-)

Fingers crossed for some great JRuby tutorials and guides coming along in the next couple of months.
