commit f185a5e8c0a3ad7cfaf5f956d1aafc1c94aa8de1
Author: Thomas Goirand <zigo at debian.org>

    Fixes for Django 1.10
    
    django.db.models.fields.subclassing has gone away entirely
    (the release notes mention that SubfieldBase has gone, but
    don't mention the removal of Creator - I'm guessing it was
    viewed as an internal API).
