[[auto-cascade-persist]]
== Cascading persistence for `@Id` and `@MapsId` fields
Previously Hibernate automatically enabled `cascade=PERSIST` for association fields annotated `@Id` or `@MapsId`.
This was undocumented and unexpected behavior, and arguably against the intent of the Persistence specification.
Existing code which relies on this behavior should be modified by addition of explicit `cascade=PERSIST` to the association field.
