Today we announced the release of Apache Jackrabbit 2.3.0. It’s the result of over nine months of development since the Jackrabbit 2.2 release, and contains changes related to over a hundred new features, improvements and bug fixes. See the release notes for the full details.
Before you rush in an upgrade all your production systems to Jackrabbit 2.3, note that this release has explicitly been marked unstable. In fact all 2.3.x releases will be unstable development releases cut directly from trunk. A stable 2.4 maintenance branch will be created in a few months for production-ready releases. See the Jackrabbit roadmap for more details about our new unstable/stable release strategy.
