+# Django REST framework 3.13
+
+## Django 4.0 support
+
+The latest release now fully supports Django 4.0.
+
+Our requirements are now:
+
+* Python 3.6+
+* Django 4.0, 3.2, 3.1, 2.2 (LTS)
+
+## Fields arguments are now keyword-only
+
+When instantiating fields on serializers, you should always use keyword arguments,
+such as `serializers.CharField(max_length=200)`. This has always been the case,
+and all the examples that we have in the documentation use keyword arguments,
+rather than positional arguments.
+
+From REST framework 3.13 onwards, this is now *explicitly enforced*.
+
+The most feasible cases where users might be accidentally omitting the keyword arguments
+are likely in the composite fields, `ListField` and `DictField`. For instance...
+
+```python
+aliases = serializers.ListField(serializers.CharField())
+```
+
+They must now use the more explicit keyword argument style...
+
+```python
+aliases = serializers.ListField(child=serializers.CharField())
+```
+
+This change has been made because using positional arguments here *does not* result in the expected behaviour.
+
+See Pull Request [#7632](https://github.com/encode/django-rest-framework/pull/7632) for more details.
