Changelog

Sourced from django-filter's changelog.

Version 2.2 (2019-7-16)

• Added DjangoFilterBackend.get_schema_operation_parameters() for DRF 3.10+ OpenAPI schema generation. (#1086)
• Added lookup_expr to MultipleChoiceFilter (#1054)
• Dropped support for EOL Python 3.4

Version 2.1 (2019-1-20)

• Fixed a regression in FilterView introduced in 2.0. An empty QuerySet was incorrectly used whenever the FilterSet was unbound (i.e. when there were no GET parameters). The correct, pre-2.0 behaviour is now restored.

  A workaround was to set strict=False on the FilterSet. This is no longer necessary, so you may restore strict behaviour as desired.

• Added IsoDateTimeFromToRangeFilter. Allows From-To filtering using ISO-8601 formatted dates.

Version 2.0 (2018-7-13)

2.0 introduced a number of small changes and tidy-ups. Please see the migration guide:
