Atlassian has released version 3.3 of JIRA, a $1200-$4800 payware J2EE-based bug tracking and project management server application. Version 3.3 adds multiple project filtering, new bulk move capabilities, extended date and number searching, and Italian and Slovakian translations, I've been using Jira lately with Jaxen and Apache. It's a definite improvement over Bugzilla. I'm not sure it really does anything that Bugzilla doesn't do (at least not anything I use) but the user interface is about a hundred times cleaner.
The Apache Jakarta Project has released Regexp 1.4, a 100% Pure Java, open source Regular Expression package. This is primarily maintenance release containing several bug fixes.
