newforms-admin: Backwards-incompatible change: Refactored prepopulate_from. There's no longer a 'prepopulate_from' option on database Field classes. Instead, there's a new 'prepopulated_fields' option on the 'class Admin'. This should be a dictionary mapping field names (as strings) to lists/tuples of field names that prepopulate them
