JRuby 1.1.3 was released today. This release includes “primarily obvious compatibility problems and performance enhancements.” The highlights of this release, per the official post by Thomas Enebo, are:
- RubyGems 1.2
- Greatly improved interpreter performance
- jrubyc compiler usability improvements and bug fixes
- Reduced memory usage and object churn
- Dozens of IO-related and core class RubySpec fixes + reduced memory for IO
- ThreadGroup fixes to resolve Mongrel “dead thread” issues
- New options/properties for tweaking JIT, thread pooling, and more
- Block invocation performance improvements
- Much faster Time performance
- Much better support for –debug
- Mentioning that context classloader fix would be nice (since it quite user visible, and many users seen/asked for it). JRUBY-2495
- 82 issues resolved since JRuby 1.1.2
