The Apache OpenJPA community is proud to announce the release of Apache OpenJPA 2.2.0. As with the prior 2.1.0 release, this distribution is based on the final JSR 317 Java Persistence API, Version 2.0 specification and passes the JPA 2.0 TCK, while remaining backwards compatible with the prior 1.2.x releases based on the Java Persistence API (JPA 1.0) part of Java Community Process JSR-220 (Enterprise JavaBeans 3.0). For a list of all the new features of JPA 2.0, please checkout the OpenJPA 2.1.0 release notes.
