+# EntityManager#getPartialReference() creates read-only entity
+
+Entities returned from EntityManager#getPartialReference() are now marked as read-only if they
+haven't been in the identity map before. This means objects of this kind never lead to changes
+in the UnitOfWork.
+
+# Fields omitted in a partial DQL query or a native query are never updated
+
+Fields of an entity that are not returned from a partial DQL Query or native SQL query
+will never be updated through an UPDATE statement.

 # Removed support for onUpdate in @JoinColumn
 
 The onUpdate foreign key handling makes absolutly no sense in an ORM. Additionally Oracle doesn't even support it. Support for it is removed.
