Overview

   These notes describe the difference between OpenJPA release 1.1.0 and the
   preceding releases, 0.9.6, 0.9.7, and 1.0.0. 

   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.

Prerequisites

   In normal usage, OpenJPA requires Java 5 or higher and a relational 
   database of some sort.

Documentation

   If you have questions about OpenJPA, a good source of information is the
   online product manual. You can find the manual for the current release as
   well as older releases of OpenJPA at
   http://openjpa.apache.org/documentation.html

   If you can't find what you're looking for in the manual or would like more
   clarification you please post to the OpenJPA development mailing list.
