+Remove ``core``
+Remove the ``core`` argument from your model fields. It is no longer

+Work with file fields using the new API
+The internal implementation of :class:`django.db.models.FileField` have changed.
+A visible result of this is that the way you access special attributes (URL,
+filename, image size, etc) of these model fields has changed. You will need to
+make the following changes, assuming your model's
+:class:`~django.db.models.FileField` is called ``myfile``:

+:ref:`model API <ref-models-fields>` documentation.
