Querydsl is a framework that enables the construction of statically typed SQL-like queries. Instead of writing queries as inline strings or externalizing them into XML files, they can be constructed via a fluentDSL/API like Querydsl. It supports JPA, JDO, Java Collections, SQL via JDBC, Lucene, and Hibernate Search.

Changes:
EclipseLink support was improved. UNION ALL support was added. Proper OSGI metadata was added in artifacts.
