The JRuby community is pleased to announce the release of JRuby 1.0.0RC3.

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

This will likely be our final release candidate before our 1.0 release.  
People are
encouraged to try out this release to help us find any remaining show 
stopper issues.  We
have spent a lot of time over the last month squashing compatibility 
bugs and we have
confidence that applications 'will just work' (tm)*.  Please try your 
applications and
libraries against JRuby and give us feedback.

In the last month we have had a record number of people come in and 
provide a patch or
report a bug.  Interest in JRuby has exploded since JavaOne and 
RailsConf, and many
development groups are now testing and deploying JRuby and JRuby on 
Rails apps in
production. This has really helped accelerate our progress and JRuby is 
looking much
better because of it.  A few honorable mentions go out to: Koichiro 
Ohba, Daniel Berger,
David Montag, Dr Nic Williams, and Jon Tirsen. 

We also want to thank all the people who hang out on IRC, 
triage/report/patch issues, and
communicate on our mailing lists.  Their interest has really helped 
shape JRuby into a
better implementation.

As we approach our 1.0 release, we encourage Ruby (and JRuby) community 
members to
contribute to a few projects key to the success of alternative 
implementations:

- The RubySpec Wiki (www.headius.com/rubyspec) has slowly been growing 
into a free,
community-driven specification of Ruby. Many people have contributed 
articles, and several
of those directly aided JRuby development. The more people contribute to 
the wiki--in any
way--the more it will begin to form a complete specification for Ruby 
the language and
Ruby the platform. Have you written RubySpec today?

- Both the Rubinius and JRuby projects have been building out their 
testing suites, to the
point that JRuby now runs more regression/compatibility tests than any 
other Ruby
implementation and Rubinius has the largest collection of RSpec 
specifications for Ruby.
We two projects have been coordinating and cooperating on these 
testing/spec suites, but
they need your help! Check out the JRuby or Rubinius source code and dig 
into the tests...
you'll be helping both projects and the community at large. For more 
test suites, check
out the RubyTests project on RubyForge, where it is hoped that all test 
suites will
eventually reside, and the ruby_test project under the Shards project on 
RubyForge.

JRuby's tests are at http://svn.codehaus.org/jruby/trunk/jruby in the 
test dir.
Rubinius's specs are at http://code.fallingsnow.net/svn/rubinius/trunk 
in the spec dir.
RubyTests is at http://rubyforge.org/projects/rubytests
RubySpec is at http://www.headius.com/rubyspec
