This guide discusses migration from Hibernate ORM version 5.1 to version 5.2. For migration from earlier versions, see any other pertinent migration guides as well.
Lots of work has been done for 6.0. One of the things 6.0 will need is a unified view of "type systems" including its own type system (Type, EntityPersister, CollectionPersister, etc) and JPA’s type system - which would mean unifying all of this in hibernate-core. Because of this and the other large changes slated for 6.0 we decided to release a 5.2 that showed a clear migration path to the changes in 6.0 but that still supported the older calls and expectations as much as possible.
