Before I start, I want to mention that Seam 3 is extremely green right now. The main motivation for jumping into now is to work out the kinks in the JSR-299 and JSF 2 implementations. Plus, I'm starting to get the word out about what's going on with Seam 3 so that you can help drive its future and be a part of the process.
With work on version 3.2 of Hibernate Search well underway and a range of very interesting features in the pipeline (eg programmatic configuration API, bulk indexing and dynamic boosting), we decided to provide some of the bug fixes also for the 3.1 version of Hibernate Search. Hence here is Hibernate Search 3.1.1 GA. On top of several bug fixes which are listed in the release notes we also upgraded Lucene from 2.4 to 2.4.1.
