Previously, copying a super object returned a copy of the instance invoking super(). Pickling a super object could pickle the instance invoking super() or fail, depending on its type and protocol. Now deep copying returns a new super object and pickling pickles the super object. Shallow copying returns the same super object.

There was a problem hiding this comment.
Should we give this a private name? All the existing ones also use public names, so I don't mind keeping this one public too.
