JRuby 1.1.5 is the fifth point release of JRuby 1.1.  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:
- Per-class method caching (improves _send_, respond_to?, and defined?)
- Constant cache dramatically improves constant lookup
- Reduced memory usage for compiled execution
- Several Java Integration regressions fixed
- Rubygems 1.3.1 and Rspec 1.1.11 upgrades
- Updated ffi (Foreign Function Interface) support
- More Ruby 1.9 mode support
- 113 bugs fixed since 1.1.4

The JRuby community is pleased to announce the release of JRuby 1.1.1!

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

JRuby 1.1.1 is the first point release of JRuby 1.1.  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:

• interpreter method dispatch speedup
• reduced memory consumption (permgen)
• fixed nasty concurrency bottleneck
• stat()/lstat() 300% faster
• improved startup time
• improved bigdecimal support
• 42 issues resolved since JRuby 1.1
