  ``copy.deepcopy()`` to class attributes in ``TestCase.setUpTestData()`` is

  :attr:`.BaseCommand.requires_system_checks` is removed.

* The ``whitelist`` argument and ``domain_whitelist`` attribute of
  ``django.core.validators.EmailValidator`` are removed.

* The ``default_app_config`` application configuration variable is removed.

* ``TransactionTestCase.assertQuerysetEqual()`` no longer calls ``repr()`` on a
  queryset when compared to string values.

* The ``django.core.cache.backends.memcached.MemcachedCache`` backend is
  removed.
