> Download JRuby for free. JRuby is the effort to recreate the Ruby interpreter in Java. JRuby is tightly integrated with Java to allow both to script any Java class and to embed the interpreter into any Java application.

JRuby is a project to provide a Java implementation of  
the Ruby language and interpreter.

JRuby 0.8.3 has been released. This version fixes a  
huge number of problems and boasts the following notables:

- irb (jirb) works
- included Java classes are dramatically faster to load  
and use. A two minute Swing example now loads in  
approximately 5 seconds.
- binding works
- every constant scoping issue we knew of has been fixed
- interpreter redesign work improved stack depth and  
brings us closer to supporting continuations
- serious concurrency error when Ruby instances are passed  
back out to Java has fixed. This was a must for  
servlet-based solutions.
- adornment of Java classes with Ruby methods via  
‘extend\_proxy’ method

Thanks to all people on the project and mailing lists for  
making JRuby a much better piece of software. Special props  
out to Charles Nutter for working so hard this development  
cycle.

The next release is going to be targetted for the beginning  
of May. We want one more release out before JavaOne. We  
are getting close to having RubyGems and Ruby on Rails  
working.
