This release has largely been a stabilization release where we have spent
more focus on Ruby compatibility. We are gearing up for a 1.0 release. Here
are some of the more significant acheivements for 0.9.9:

Major compatibility and performance overhaul of String, Array, Hash
Many YAML and Marshalling issues have been fixed
Java Integration overhaul fixing many outstanding issues
180 Jira issues resolved
Several more bottlenecks removed
Rails applications like Mephisto and plugins like Goldberg are running without hitches
Performance has improved by 40% over 0.9.8 based on YARV benchmarks
With all the hard work done by Marcin Mielżyński and Bill Dortch we are adding
them as core committers. Their contributions have made a huge difference in
our progress as of late.
We also want to thank all people who hang out on IRC, triage/report/patch
issues, and communicate on our mailing lists. Their interest has really
helped shape JRuby into a better implementation.

Please take JRuby 0.9.9 for a spin and help us root out the last issues
before our 1.0 release!
