• 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
