JRuby 1.3.0 Released

Wednesday, June 03 2009

The JRuby community is pleased to announce the release of JRuby 1.3.0.

  • Homepage: http://www.jruby.org/
  • Download: http://dist.codehaus.org/jruby/

The fixes in this release are primarily obvious compatibility problems and performance enhancements. Our goal is to put out point releases more frequently for the next several months (about 3-4 weeks a release). We want a more rapid release cycle to better address issues brought up by users of JRuby.

Highlights:

  • Fixes so that JRuby runs in restricted environments better like GAE/J
  • Accessing primitive Java arrays are about 10x faster
  • timeout.rb is now ~40% faster
  • Method cache performance improvements
  • irb works in –1.9 mode now
    • Additional Miscellaneous 1.9 fixes
  • rubygems 1.3.3, rake 0.8.7, and rspec 1.2.6 upgrades
  • 66 bugs fixed since 1.2.0
