This performance and stability focused beta is out http://in.relation.to/Bloggers/HibernateSearch310Beta2FocusOnLockContention Special thanks to Sanne for all the work on the Lucene backend. CR1 is planned mid-november-ish with a GA following shortly. The CR will contains some additional Lucene 2.4 alignments, performance optimization we have in mind and a few additional features (if time permits). -- Emmanuel Bernard http://in.relation.to/Bloggers/Emmanuel | http://blog.emmanuelbernard.com | http://twitter.com/emmanuelbernard Hibernate Search in Action (http://is.gd/Dl1)
