Hibernate 6.5.0.Final
6.5 has gone final!
I had so many interesting new things to talk about in the summary of Jakarta Persistence 3.2 that I forgot to mention an important thing we’re taking away.
Hibernate ORM version 6.5
already received a couple candidate release versions, and a final release will follow shortly. This post highlights one of the improvements that comes with this version: efficient retrieval of non-identifier database generated values.
Jakarta Data is a new specification for persistence in Java, scheduled for release as part of the EE 11 platform. In a previous post I introduced the basic features of a Jakarta Data repository, with a strong emphasis on how Jakarta Data provides compile-time type safety, enabling static analysis performed by an annotation processor.
This involved moving some information that used to be expressed in procedural code into:
-
annotations like
@Query
and@Find
, and -
the names and types of repository method parameters.
Today we’re going to talk about some more dynamic features of Jakarta Data. You might anticipate that these would come with a loss of type safety, but we’ve found a way to avoid that. The essential ingredient is a static metamodel.
Hibernate 6.5.0.CR2
6.5 brings many new features, in addition to many improvements and fixes.
We are pleased to announce the releases of Hibernate Search 7.1.1.Final, 7.0.1.Final and 6.2.4.Final.
While these releases are mainly to address some minor documentation discrepancies, they also bring compatibility with newer versions of Elasticsearch and OpenSearch and a few bugfixes.
Today we’re excited to announce that Hibernate is moving to the Commonhaus Foundation. For the last 20 years, development of Hibernate has been funded and sponsored by JBoss, and then by Red Hat. This support will continue just as before, since Hibernate remains a critical component of JBoss EAP, WildFly, and Quarkus, but the project itself will now be hosted on neutral ground.

One of the most important experiences of my career was working with Linda DeMichiel from Sun, Mike Keith from TopLink, Evan Ireland from Sybase, and others, to design and write the first version of the Java Persistence specification.
Today this technology enjoys broad acceptance, even among former critics. But in recent years, despite a name change to Jakarta Persistence, the spec has not evolved rapidly. Not until now, that is. Over the last year or so, Lukas Jungmann from Oracle and I have been working rather hard to bring you the biggest release of Persistence in a long time.
This post will concentrate on new features we’ve added to Jakarta Persistence. It’s worth mentioning that quite a lot of work has gone into clarifying the semantics of existing features, and rewriting certain sections of the spec for clarity and readability. This is an ongoing effort. The spec is more than 500 pages in length; rewriting such text without accidentally changing its meaning is a slow and painstaking process.
In a previous post I talked about Jakarta Data. Alignment of the two specifications has been a further priority.

Jakarta Data is a new specification for persistence in Java, scheduled for release as part of the EE 11 platform. Whereas Jakarta Persistence provides a mature and extremely feature-rich foundation for object/relational mapping solutions like Hibernate, Jakarta Data aims to offer a somewhat simplified programming model, but one which is also suitable for use with non-relational databases.
