In case you haven't heard already we released a new version of OYE today. You can go here to get it. Some of the new stuff includes:
Advanced Search
More Customization Options
Firefox 2 Support
Metadata query support (limited fields)
More Languages Supported (but still no Klingon)
Performance Improvements
Updated Lucene Index
Updated JVM
Lots of bug fixes...
If I told you how many bugs there are you and my employer would probably kill me. :-)
