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


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

- 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
