[ANN] JRuby 1.2.0 Released


Thomas Enebo

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.'
the front. 1.3, 1.4, ..., 1.x will just be minor releases of our current
major release.

- 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.
