The JRuby team is pleased to announce the release of JRuby 0.9.8.

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

This release has some great improvements:

- Ruby on Rails support. We have been working hard on getting Rails own unit
tests running and over 98%* of them now run successfully. We feel things are
running well enough to invite Ruby users to kick the tires and help root out
any final issues.
- Ruby classes can extend concrete/abstract Java classes and override methods
- New Java primitive array syntax
- Reimplementation of String, Numeric classes, and Array to be more correct
and performant
- Significant bottlenecks have been identified. In some cases IO is 6.5x
faster than previous releases. Java included classes are significantly
faster than in the past.
- 225 Jira issues resolved since last release

At the beginning of this development cycle we added Nick Sieger as a committer
to JRuby. Nick has been a welcome addition to the team.

Special thanks to Marcin Mielżyński for his tireless work in rewriting a
number of core classes to be much more correct and quick. His attention to
detail has rooted out many corner cases.

The amount of IRC conversations, mailing list threads, bug reports, patches,
and blog entries in the community has been a great help and our community is
really making a huge difference in how fast JRuby is improving. The amount
of progress is really staggering....

We are actively looking for folks with pure-Ruby Rails apps (i.e. no critical extensions) to help test them out on JRuby 0.9.8. I've already heard from a couple folks whose apps started up and "just worked". We know things aren't going to be perfect with Rails support, but it's pretty darn close.

Feel free to communicate with me or Tom directly about issues you find, or even better: join the mailing lists and report issues at jruby.org.
