The internal ``EditHandler`` methods ``bind_to_model`` and ``bind_to_instance`` have been deprecated, in favour of a new combined ``bind_to`` method which accepts ``model``, ``instance``, ``request`` and ``form`` as optional keyword arguments. Any user code which calls ``EditHandler.bind_to_model(model)`` should be updated to use ``EditHandler.bind_to(model=model)`` instead; any user code which calls ``EditHandler.bind_to_instance(instance, request, form)`` should be updated to use ``EditHandler.bind_to(instance=instance, request=request, form=form)``.
