This release has some great improvements:

At the beginning of this development cycle we added Nick Sieger as a committer
to JRuby. Nick has been a welcome addition to the team.

Special thanks to Marcin Mielżyński for his tireless work in rewriting a
number of core classes to be much more correct and quick. His attention to
detail has rooted out many corner cases.

The amount of IRC conversations, mailing list threads, bug reports, patches,
and blog entries in the community has been a great help and our community is
really making a huge difference in how fast JRuby is improving. The amount
of progress is really staggering....
