Version 3.14.0 proposal (#8599)

* Version 3.14.0

* Update docs/community/release-notes.md to use proper links.

Co-authored-by: Adam Johnson <me@adamj.eu>

* Add community announcement page for version 3.14

* Remove deprecated NullBooleanField.

* Change openapi _get_reference removal to 3.15

This deprecation was never released in the 3.13.x series and therefore
can't be removed at the same time the replacement is released.

* Removing deprecated openapi methods.

+# Django REST framework 3.14
+
+## Django 4.1 support
+
+The latest release now fully supports Django 4.1.
+
+Our requirements are now:
+
+* Python 3.6+
+* Django 4.1, 4.0, 3.2, 3.1, 2.2 (LTS)
+
+## `raise_exceptions` argument for `is_valid` is now keyword-only.
+
+Calling `serializer_instance.is_valid(True)` is no longer acceptable syntax.
+If you'd like to use the `raise_exceptions` argument, you must use it as a
+keyword argument.
+
+See Pull Request [#7952](https://github.com/encode/django-rest-framework/pull/7952) for more details.
+
+## `ManyRelatedField` supports returning the default when the source attribute doesn't exist.
+
+Previously, if you used a serializer field with `many=True` with a dot notated source field
+that didn't exist, it would raise an `AttributeError`. Now it will return the default or be
+skipped depending on the other arguments.
+
+See Pull Request [#7574](https://github.com/encode/django-rest-framework/pull/7574) for more details.
+
+
+## Make Open API `get_reference` public.
+
+Returns a reference to the serializer component. This may be useful if you override `get_schema()`.
+
+## Change semantic of OR of two permission classes.
+
+When OR-ing two permissions, the request has to pass either class's `has_permission() and has_object_permission()`.
+
+Previously, both class's `has_permission()` was ignored when OR-ing two permissions together.
+
+See Pull Request [#7522](https://github.com/encode/django-rest-framework/pull/7522) for more details.
+
+## Minor fixes and improvements
+
+There are a number of minor fixes and improvements in this release. See the [release notes](release-notes.md) page for a complete listing.
