* Serializers were including all superclass fields in their output. Now only local fields are included.
* Implicit OneToOne primary keys were not correctly added to the metamodel, so they were always marked to be serialized, even though they were primary
* Model saving was too aggressive about creating new parent class instances during deserialization. Raw save on a model now skips saving of the parent class.
