Upgrading Django 1.9.5 from DjangoCMS 3.2.3 to 3.2.4 causes South issue with migration

[JoeJasinski]

I just upgraded a working copy of DjangoCMS 3.2.3 to DjangoCMS 3.2.4. It looks like the migration "0009_added_meta_fields.py" has references to south, which no longer exists. This causes migrate to break. Migrate works with DjangoCMS 3.2.3.

>>> import south
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: No module named south
>>> import django
>>> django.VERSION
(1, 9, 5, 'final', 0)
>>> import cms
>>> cms.__version__
'3.2.4'

/Users/jjasinski/Sites/joejasinski/envs/joejasinski/lib/python2.7/site-packages/cms/migrations/0009_added_meta_fields.py

# -*- coding: utf-8 -*-
import datetime
from south.db import db
from south.v2 import SchemaMigration
from django.db import models

Here is the actual error:

./manage.py migrate --list
..
