Title: OpenJPA 2.4.x

<a name="OpenJPA-2.4.3-OpenJPA-2.4.3"></a>
# OpenJPA 2.4.3

The Apache OpenJPA community is proud to announce the release of Apache
OpenJPA 2.4.3.
This distribution is based on the final [JSR 317 Java Persistence API,
Version 2.0](http://jcp.org/en/jsr/detail?id=317) 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).

Additional information on the OpenJPA project may be found at [the project web site](http://openjpa.apache.org).
