What's new

Hibernate ORM 6.0 is still in development:

  • some features may be incomplete;

  • newly introduced features may change in a backward-incompatible way before the stable release.

We encourage you to give it a try and to let us know of any bugs or problems you encounter.

Latest release announcement (2021-10-11): 6.0.0.Beta1.

A detailed list of new features, improvements and fixes in this series can be found on our issue tracker.

JDBC Performance

6.0 switches reading from JDBC ResultSet by name to reading by position. This required significant changes to the Hibernate type system.

HQL Translation Performance

6.0 switched from Antlr v2 to Antlr v4 for its HQL translation. Antlr v4 itself is more performant. Additionally we refactored the grammars to be more efficient

Criteria Translation Performance

In previous versions of Hibernate, JPA Criteria queries were translated by first rendering the Criteria as an HQL query. 6.0 changes this so that HQL and Criteria are both translated into the same form : the Semantic Query Model (SQM).
