22.1

Version 22.1

Version 2.4.0

• SECURITY: Added a MaxValueValidator to the form field for
  NumberFilter. This prevents a potential DoS attack if numbers with very
  large exponents were subsequently converted to integers.

  The default limit value for the validator is 1e50.

  The new NumberFilter.get_max_validator() allows customising the used
  validator, and may return None to disable the validation entirely.

• Added testing against Django 3.1 and Python 3.9.

  In addition tests against Django main development branch are now required to
  pass.

Version 2.3.0

https://github.com/carltongibson/django-filter/blob/master/CHANGES.rst#version-230-2020-6-5

Version 2.2

Highlights:

• 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 2.1.0

• 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

2.0 introduced a number of small changes and tidy-ups.
