Hibernate ORM 7.3 Final was released a few weeks ago and today 7.3.1 will be released.

Details about the release, as well as links to important resources, can be found at https://github.com/hibernate/hibernate-orm/releases/tag/7.3.0.

Some of the new features include -

  1. Addition of the new KeyType enum that allows find() and findMultiple() to perform a load based on natural id in addition to identifier.

  2. Addition of @NaturalIdClass which models a non-aggregated composite natural id for the purpose of loading, very much like @IdClass does for non-aggregated identifiers.

  3. Support for Jackson 3 JSON and XML FormatMapper implementations
