Djangorestframework-jsonapi

Added

* Add new pagination classes based on JSON:API query parameter *recommendations*:
* `JsonApiPageNumberPagination` and `JsonApiLimitOffsetPagination`. See [usage docs](docs/usage.mdpagination).
* Add `ReadOnlyModelViewSet` extension with prefetch mixins
* Add support for Django REST framework 3.8.x
* Introduce `JSON_API_FORMAT_FIELD_NAMES` option replacing `JSON_API_FORMAT_KEYS` but in comparison preserving
values from being formatted as attributes can contain any [json value](https://jsonapi.org/format/#document-resource-object-attributes).
* Allow overwriting of `get_queryset()` in custom `ResourceRelatedField`

Deprecated

* Deprecate `PageNumberPagination` and `LimitOffsetPagination`. Use `JsonApiPageNumberPagination` and `JsonApiLimitOffsetPagination` instead.
* To retain deprecated values for `PageNumberPagination` and `LimitOffsetPagination` create new custom class like the following in your code base:
python
class CustomPageNumberPagination(PageNumberPagination):
page_query_param = "page"
page_size_query_param = "page_size"

class CustomLimitOffsetPagination(LimitOffsetPagination):
max_limit = None

and adjust `REST_FRAMEWORK['DEFAULT_PAGINATION_CLASS']` setting accordingly.
* Deprecate `JSON_API_FORMAT_KEYS`, use `JSON_API_FORMAT_FIELD_NAMES`.

Fixed

* Performance improvement when rendering included data

Added

* Add support for Django 2.0.

Removed

* Drop support for Django 1.8 - 1.10 (EOL)

Changed

Fixed
* When `JSON_API_FORMAT_KEYS` is False (the default) do not translate request

Added

* Add support for Django REST framework 3.5 and 3.6

* Fix wrong resource type for reverse foreign keys
* Fix documentation typos

Added

* Convert `include` field names back to snake_case
* Raise a `ParseError` if an `id` is not included in a PATCH request

Fixed

* Fix Django 1.10 compatibility
* Performance enhancements to reduce the number of queries in related payloads
* Fix issue where related `SerializerMethodRelatedField` fields were not included even if in `include`
* Fix bug that prevented `fields = ()` in a serializer from being valid
* Fix stale data returned in PATCH to-one relation
