While our focus has been on the exciting new improvements in Hibernate Search 4, since the release of the last stable release 3.4.0.Final we had much interesting feedback from the community, including bugreports and patches.
The Hibernate team is pleased to announce Hibernate Search 3.4 which comes with couple of new features most notably faceting: we are continuing the trend of 3.3 where the focus was on simplifying queries). But the bulk of the work has been around performance optimization, you should see the benefits in your applications especially when the domain model is getting complex.
Moving from Alpha1 to Beta1, I am happy to announce the release of Hibernate Search 3.4.0.Beta1. The release includes an upgrade to Hibernate Core 3.6.2 and the usual bug fixes (see Jira release notes for all the gory details).
