The JRuby community is pleased to announce the release of JRuby 1.1.2!

JRuby 1.1.2 is the second 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:
- Startup time drastically reduced
- YAML symbol parsing >100x faster
- Performance, threading, and stack depth improvements for method calls
- Fixed several nested backref problems
- Fixed bad data race (JRUBY-2483)
- Gazillions of bigdecimal issues fixed (all?)
- 95 issues resolved since JRuby 1.1.1
