- added query_cls keyword argument to sessionmaker(); allows user-defined Query subclasses to be generated by query(). - added @attributes.on_reconstitute decorator, MapperExtension.on_reconstitute, both receieve 'on_load' attribute event allowing non-__init__ dependent instance initialization routines. - push memusage to the top to avoid pointless heisenbugs - renamed '_foostate'/'_fooclass_manager' to '_sa_instance_state'/'_sa_class_manager' - removed legacy instance ORM state accessors - query._get() will use _remove_newly_deleted instead of expunge() on ObjectDeleted, so that transaction rollback restores the previous state - removed MapperExtension.get(); replaced by a user-defined Query subclass - removed needless **kwargs from query.get() - removed Session.get(cls, id); this is redundant against Session.query(cls).get(id) - removed Query.load() and Session.load(); the use case for this method has never been clear, and the same functionality is available in more explicit ways
