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

Jakarta JPA 2.2 and 3.0

Hibernate ORM 5.5 adds new artifacts with the artifact id suffix "-jakarta" like hibernate-core-jakarta.

The hibernate-core-jakarta artifact implements the Jakarta JPA 3.0 specification, while the hibernate-core artifact still implements the Jakarta JPA 2.2 specification.

The artifacts are both certified as compatible implementations:

Please note that the Jakarta artifacts are still considered experimental.

Bytecode enhancement

The bytecode enhancement configuration was adapted to turn on enhancement-as-proxy by default and remove the switch for configuring this.
