The JRuby community is pleased to announce the release of JRuby 1.0.1.

JRuby 1.0.1 is a minor release of our stable branch. The fixes for this  
release are obvious compatibility issues that we feel are low risk. Our  
intention is to periodically push out point releases to help better  
support  
production uses of JRuby.

Highlights:

- Fixed a issue which caused most multipart processing to not work
- Fixed issue with sockets that affected some aspects of net/\* libraries
- Fixed network timeout issue for large packets
- 28 issues resolved
