The JRuby community is pleased to announce the release of JRuby 1.2.0!

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

JRuby 1.2.0 has fixed many many compatibility issues and continued to
improve general performance. Due to popular demand we have a new versioning
system. 1.x.y was our old number system where x was the major release
and y
was the minor release. Our new system just chops off the vestigial '1.'
from
the front. 1.3, 1.4, ..., 1.x will just be minor releases of our current
major release.

Highlights:
- Improved Ruby 1.9 support (via --1.9)
- Compiler now works
- Almost all of the missing 1.9 methods have been added
- New experimental --fast flag which does more aggressive optimizations
- Large scale compiler and runtime cleanup and performance audit
- Parsing is 3-6x faster now.
- Preliminary android support (Ruboto)
- Rails pathname issue fixed on Windows
- Major bug triage since last release
- 1052 revisions since 1.1.6
- 256 bugs fixed since 1.1.6

In addition to thanking everyone in the JRuby community who always helps
us improve JRuby,
we also want to give a special thanks to all those who gave us feedback
during the release
candidate phase. This helped us find a number of serious blockers.
