Thanks guys!

Fixed #139. Overriding declared fields must now use serializers.SerializerMethodField() and are
handled by stock DRF. We don’t need any custom functionality for this.
Added support for Django REST Framework v3.10.x
Dropped Python 2.x support
v1.8.0¶
Release date: 2018-04-16
This release was pulled because of critical errors in the test suite.
Dropped support for Django v1.10.x and added support for Django v2.0.x
Updated minimum Django REST Framework requirement to v3.7

Bumping minimum support for Django to v1.10.
Bumping minimum support for Django REST Framework to v1.6.0
Adding support for Elasticsearch 2.x Haystack backend
Updated docs with correct name for libgeos-c1.
Updated .travis.yml with correct name for libgeos-c1.
Fixed an issue where queryset in the whould be evaluated if attribute is set but has no results,
thus triggering  the wrong clause in condition check. PR#88 closes #86.
Fixed #61. Introduction of custom serializers for serializing faceted objects contained a
breaking change.
This release include breaking changes to the API
Dropped support for Python 2.6, Django 1.5, 1.6 and 1.7
Will follow Haystack’s supported versions
Removed deprecated SQHighlighterMixin.
Removed redundant BaseHaystackGEOSpatialFilter. If name of indexes.LocationField needs to be changed, subclass the HaystackGEOSpatialFilter directly.
Reworked filters:
More consistent naming of methods.
All filters follow the same logic for building and applying filters and exclusions.
All filter classes use a QueryBuilder class for working out validation and building queries which are to be passed to the SearchQuerySet.
Most filters does not inherit from HaystackFilter anymore (except HaystackAutocompleteFilter and HaystackHighlightFilter) and will no longer do basic field filtering. Filters should be properly placed in the filter_backends class attribute in their respective order to be applied. This solves issues where inherited filters responds to query parameters they should ignore.
HaystackFacetSerializer narrow_url now returns an absolute url.
HaystackFacetSerializer now properly serializes MultiValueField and FacetMultiValueField items as a JSON Array.
HaystackGenericAPIView.get_object() optional model query parameter now requires a app_label.model instead of just the model.
Extracted internal fields and serializer from the HaystackFacetSerializer in order to ease customization.
HaystackFacetSerializer now supports all three builtin pagination classes, and a hook to support custom pagination classes.
Extracted the more-like-this detail route and facets list route from the generic HaystackViewSet.
Support for more-like-this is available as a drf_haystack.mixins.MoreLikeThisMixin class.
Support for facets is available as a drf_haystack.mixins.FacetMixin class.
Fixed a bug where ignore_fields on HaystackSerializer did not work unless exclude evaluates
to True.
Removed elasticsearch from install_requires. Elasticsearch should not be a mandatory requirement,
since it’s useless if not using Elasticsearch as backend.
Proper support for Multiple search indexes (Github #22).
Experimental support for Term Boost (This seems to have some issues upstreams,
so unfortunately it does not really work as expected).
Support for negate in filters.
Support for More Like This results (Github #10).
Deprecated SQHighlighterMixin in favor of HaystackHighlightFilter.
HaystackGenericAPIView now returns 404 for detail views if more than one entry is found (Github #19).
Added support for field lookups in queries, such as field__contains=foobar.
Check out Haystack docs
for details.
Added default permission_classes on HaystackGenericAPIView in order to avoid crash when
using global permission classes on REST Framework. See Permissions for details.
Fixed issues for Geo spatial filtering on django-haystack v2.4.x with Elasticsearch.
A serializer class now accepts a list or tuple of ignore_field to bypass serialization.
Added support for Highlighting.
HaystackGenericAPIView().get_object() now returns Http404 instead of an empty SearchQueryset
if no object is found. This mimics the behaviour from GenericAPIView().get_object().
Removed hard dependencies for geopy and libgeos (See Github #5). This means
that if you want to use the HaystackGEOSpatialFilter, you have to install these libraries
manually.
Fixed MissingDependency error when using another search backend than Elasticsearch.
Fixed converting distance to D object before filtering in HaystackGEOSpatialFilter.
Added Python 3 classifier.
