These notes describe the difference between OpenJPA release 1.0.0 and the
preceding releases, 0.9.6 and 0.9.7. 1.0.0 is the first major release
since OpenJPA graduated to an Apache top level project (TLP), and contains
many new features and bugfixes.
** New Features
* [OPENJPA-92] - Support for H2 Database Engine
* [OPENJPA-93] - Sequence generation in a JTA environment should not require non-JTA datasource
* [OPENJPA-94] - Allow MappingTool and persistence.xml to support drop-create for database schema
* [OPENJPA-182] - db2 update lock syntax WITH <isolation> USE AND KEEP UPDATE LOCKS
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.
** Tasks
* [OPENJPA-36] - Add cwiki url to incubator status page
Additional information on the OpenJPA project may be found at the project
web site: http://openjpa.apache.org
** Tests
* [OPENJPA-40] - Testing OpenJPA and Spring integration fails

Prerequisites
OpenJPA requires Java 1.5 but will not compile with Java 6. For more
detail please see http://issues.apache.org/jira/browse/OPENJPA-5
Documentation
