To avoid creating so many joins, and also in general, we recommend that you use lazy fetching i.e. `@ManyToOne(fetch = FetchType.LAZY)` or `@OneToOne(fetch = FetchType.LAZY)` for most associations, but this is especially important if you have multiple self-referencing associations as you can see in the example. + +=== Removal of legacy Hibernate Criteria API + +The legacy Hibernate Criteria API which was deprecated back in Hibernate 5.x was removed in 6.0. +Usually, all queries using the legacy API can be modeled with the JPA Criteria API. +In some cases it is necessary to use the Hibernate JPA Criteria extensions. + +=== Removal of loader walkers + +The special walkers/visitors in the loader package were removed.
