JRuby 1.1.3 has been released, with JRuby versions available for download at Codehaus. The major changes in this maintenance release, from the release notes:- RubyGems 1.2
- Greatly improved interpreter performance
- jrubyc compiler usability improvements and bug fixes
- Reduced memory usage and object churn
- Dozens of IO-related and core class RubySpec fixes + reduced memory for IO
- ThreadGroup fixes to resolve Mongrel "dead thread" issues
- New options/properties for tweaking JIT, thread pooling, and more
- Block invocation performance improvements
- Much faster Time performance
- Much better support for --debug
- Mentioning that context classloader fix would be nice (since it quite user visible, and many users seen/asked for it). JRUBY-2495
- 82 issues resolved since JRuby 1.1.2
In the past, we even had to increase the memory limits for JRuby up to 500Mb so that RubyGems could work without out of memory errors. Not anymore! RubyGems 1.2 is a fantastic release that speed things up dramatically, and JRuby 1.1.3 comes with it by default. Just try it and you'll be amazed, I promise! :) Not only that, but RubyGems 1.2 is much easier to customize to suit the needs of particular implementations/platforms, and we've taken full advantage of that, eliminating essentially all custom JRuby-specific patches over the RubyGems sources.The number of JRuby libraries and integration support keeps on growing. A new project aims to provide support for Rubinius Foreign Function Interface (FFI). The first mention comes from Charles Nutter in a mail to the jruby-dev list:
Welcome Wayne Meissner! Wayne is one of the primary folks behind JNA, which has totally saved us (chmod, symlink, other posix, UNIX sockets, and more). He's also implemented jruby-ffi, which should have its first release soon...and manages to pass many specs for Rubinius's fully FFI-based zlib.rb.Wayne Meissner is now a JRuby committer. The Github mirror of the JRuby repository shows a recent commit with the message "Merge branch 'ffi'", and a search for 'ffi' in the commit messages allows to track progress of the FFI support.
