JRuby 1.1.4 Released

The JRuby project, an implementation of the Ruby language on the JVM, has released version 1.1.4. Though a minor (maintenance) release, the new version introduces a number of improvements, including:

• A substantially re-written Ruby-Java integration layer.
• Big improvements in performance: about 2-20x.
• Reduction of garbage collection cycles (efficient memory usage).
• Experimental support for Ruby 1.9 (via the --1/9 flag)
• Started support for the win32 API
• Ported Rubinius' FFI subsystem for integrating with C libraries
• Addition of OSGi metadata to the jruby.jar
• Lots of bug fixes (72 issues resolved since version 1.1.3)
