The JRuby community is pleased to announce the release of JRuby 1.0.2. Homepage: [http://www.jruby.org/](http://www.jruby.org/) Download: [http://dist.codehaus.org/jruby/](http://dist.codehaus.org/jruby/) JRuby 1.0.2 is a minor release of our stable 1.0 branch. The fixes in this release include primarily obvious compatibility issues that we felt were low risk. We periodically push out point releases to continue supporting production users of JRuby 1.0.x. Highlights: - Fixed several nasty issues for users on Windows - Fixed a number of network compatibility issues - Includes support for Rails 1.2.5 - Reduced memory footprint - Improved File IO performance - trap() fix - 99 total issues resolved since JRuby 1.0.1 Special thanks to the new JRuby contributors who rose to Charlie’s challenge to write patches for some outstanding bugs: Riley Lynch, Mathias Biilmann Christensen, Peter Brant, and Niels Bech Nielsen.
