* Add official support for Django 5.1 Following the supported Python versions: https://docs.djangoproject.com/en/stable/faq/install/ * Add tests to cover compat with Django's 5.1 LoginRequiredMiddleware * First pass to create DRF's LoginRequiredMiddleware * Attempt to fix the tests * Revert custom middleware implementation * Disable LoginRequiredMiddleware on DRF views * Document how to integrate DRF with LoginRequiredMiddleware * Move login required tests under a separate test case * Revert redundant change * Disable LoginRequiredMiddleware on ViewSets * Add some integrations tests to cover various view types
