Migrations autodetector

• https://docs.djangoproject.com/en/dev/releases/4.0/#migrations-autodetector-changes

The migrations autodetector now uses model states instead of model classes .

Also, migration operations for ForeignKey and ManyToManyField fields no longer specify attributes which were not passed to the fields during initialization.

As a side-effect, running makemigrations might generate no-op AlterField operations for ManyToManyField and ForeignKey fields in some cases.
