JRuby 9.1.8.0 Released

Monday, March 06 2017

The JRuby community is pleased to announce the release of JRuby 9.1.8.0

JRuby 9000 is the newest major version of JRuby, representing years of effort and large-scale reboots of several JRuby subsystems. It is expected to be compatible with Ruby 2.x and stay in sync with C Ruby. JRuby 9.1.8.0 is our latest releaseā€¦

Major features of JRuby 9000:

  • Ruby 2.x compatibility
  • A new optimizing runtime based on a traditional compiler design
  • New POSIX-friendly IO and Process
  • Fully ported encoding/transcoding logic from MRI

If you do find issues then report them on using our issue tracker at http://bugs.jruby.org. We also encourage users to join our IRC channel (#jruby on Freenode) and mailing lists. You may also follow @jruby on Twitter for updates.

  • Fixed intermittent DynamicScope size errors
  • Concurrency fixes to jitting of blocks (mostly seen as previous bullet).
