When DRF 3.14 is released, these exception classes will be meaningless,
so we can delete them (this has always been done).
A previous PR removed the last incidence of `RemovedInDRF313Warning`,
but didn't outright delete the class for fear of shipping a breaking
change: https://github.com/encode/django-rest-framework/pull/8589
* 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.

* Change semantic of OR of two permission classes
The original semantic of OR is defined as: the request pass either of the two has_permission() check, and pass either of the two has_object_permission() check, which could lead to situations that a request passes has_permission() but fails on has_object_permission() of Permission Class A, fails has_permission() but passes has_object_permission() of Permission Class B, passes the OR permission check. This should not be the desired permission check semantic in applications, because such a request should fail on either Permission Class (on Django object permission) alone, but passes the OR or the two.
My code fix this by changing the semantic so that the request has to pass either class's has_permission() and has_object_permission() to get the Django object permission of the OR check.

* Fixes that namespaced views now also appear in the extra actions
Before this fix, namespaced views would not appear in the extra actions. With this fix they do.
* Flake fix
In the "Creating custom mixins" documentation, the code example recommends using
```python
if self.kwargs[field]
```
However, if the correct field is not present in kwargs, a KeyError arises.
A more secure option is tu use .get() to validate that the field is contained in the kwargs dictionary:
```python
if self.kwargs.get(field)
```
I found it unclear how the model was determined for `DjangoModelPermissions`. The docs say you need a `queryset` or `get_queryset`, but not that the value returned from those is what determines the model that is used.
Per the deprecation warnings (which have been raised since DRF 3.11),
`set_context()` was planned not to be supported in DRF 3.13. I think we
can safely delete it, in favor of `requires_context`.
From the 3.11 announcement:
> Previous our approach to this was that implementations could include a
> `set_context` method, which would be called prior to validation. However
> this approach had issues with potential race conditions. We have now
> move this approach into a pending deprecation state. It will continue to
> function, but will be escalated to a deprecated state in 3.12, and
> removed entirely in 3.13.
Why keep `RemovedInDRF313Warning` around?
=========================================
It's a bit odd that version 3.13 includes an exception class describing
things which are to be deleted in 3.13, but I've opted to keep the (now
unreferenced) class around, for fear of breaking others' setup.
(For example, if projects have a `filterwarnings` setup meant to
intercept `rest_framework.RemovedInDRF313Warning`, an error will be
thrown due to an unresolvable reference).
PR #7531 resolved issue #7433 by updating `ErrorDetails.__eq__` to correctly
handle the `NotImplemented` case. However, Python 3.9 continues to issue the
following warning:
DeprecationWarning: NotImplemented should not be used in a boolean context
This is because `__ne__` still doesn't handle the `NotImplemented` case
correctly. In order to avoid this warning, this commit makes the same change
for `__ne__` as previously made for `__eq__`.
Add a backwards compatibility shim for Django versions that have no (or an incompatible)
django.utils.http.parse_header_parameters implementation.
Thanks to Shai Berger for review.

If you set a custom timezone for a DateTimeField, the function
self.default_timezone() is still called, since fallback params to
getattr are still evaluated.
This rewrites to use hasattr, so the fallback case is only executed if
it will actually be used. If you render a lot of DateTimeFields in a
serializer, the time spent evaluating default_timezone() once for each
of them can accumulate to quite a bit, which is just unused work in the
case where timezone is already specified on the field.
* Handle unset fields with 'many=True'
The docs note:
When serializing fields with dotted notation, it may be necessary to
provide a `default` value if any object is not present or is empty
during attribute traversal.
However, this doesn't work for fields with 'many=True'. When using
these, the default is simply ignored.
The solution is simple: do in 'ManyRelatedField' what we were already
doing for 'Field', namely, catch possible 'AttributeError' and
'KeyError' exceptions and return the default if there is one set.
