The JRuby community is pleased to announce the release of JRuby 1.4.0RC1

Homepage: [http://www.jruby.org/](http://www.jruby.org/)  
Download: [Downloads — JRuby.org](http://www.jruby.org/download)

JRuby 1.4.0 Release Candidate 1 ends a long release cycle in which we  
resolved a huge number of issues. The headline feature is a move to  
Ruby 1.8.7 support, in line with Rails’ own plans to make 1.8.7 the  
required  
minimum version of Ruby.

We have also gotten more serious about out 1.9 support (–1.9). The  
bigger applications mostly just work at this point, but we still have a  
ways to go on 1.9 support. Please try your 1.9 code in JRuby and help  
us  
firm things up.

Bug reports welcome and requested!

**Please try your apps against 1.4.0RC1 ASAP and report problems**

Highlights:

- JRuby is now compatible with 1.8.7 patchlevel 174

- New YAML parser Yecht (bug-for-bug compatible with Syck!)

- Improved Java Integration Support

- Windows installer

- New embedding framework

- Many 1.9 mode (–1.9) fixes

- rubygems 1.3.5

- Much better error reporting

- 205 bugs fixed since 1.3.1

David C. has done a great job wrestling with Rubyspec failures and  
coming up with patches.

Yoko H. has totally revamped our embedding APIs and created a new  
API  
called Red Bridge. This should address all of the reported embedding  
issues.
