Release Notes for OpenJPA

Overview

These notes describe the difference between OpenJPA release 1.0.2 and the preceding releases. 1.0 is the first major release since OpenJPA graduated to an Apache top level project (TLP), and contains many new features and bugfixes.

OpenJPA is a feature-rich implementation of the persistence part of Java Community Process JSR-220 (Enterprise JavaBeans 3.0), which is known as the Java Persistence API (JPA). OpenJPA can be used as a stand-alone POJO persistence layer, or it can be integrated into any EJB3.0 compliant container and many lightweight frameworks. This release of OpenJPA is 100% compliant with the JPA specification.
