The Apache OpenJPA community is proud to release a SNAPSHOT distribution of
OpenJPA 2.4.2. 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 prior releases based on the
Java Persistence API (JPA 1.0) part of Java Community Process JSR-220
(Enterprise JavaBeans 3.0).
