JRuby

The JRuby community is pleased to announce the release of JRuby 1.2.0RC2

Homepage: https://www.jruby.org/

Download: https://dist.codehaus.org/jruby/

JRuby 1.2.0RC2 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.

***Please try your apps against 1.2.0RC2 ASAP and report problems***

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

- 232 bugs fixed since 1.1.6
