2.5.0` constitutes a major, backwards incompatible release that factors custom Django models and the `import_data` management command out of `django-councilmatic`. Instead, `django-councilmatic>=2.5.0` extends the Django implementation of the Open Civic Data standard, `python-opencivicdata`, and updates application code throughout to accomodate the model changes. Approaches for further extension of the base models are outlined in the README.
