==========================
- Drop Django REST Framework 3.3 support (239).
- Removed the Presets from the code (249).
- Removed from model serializers, and test code.
- Translation strings have been removed.
- Swagger documentation updated to reflect this API change.
- Removed fields that reference preset models in forms and preset args tables through a Django migration (259).
.. warning::
Validation rules are handled by field validations, and the historical Preset mechanism is now deprecated. Front-end integration should take into account that the form ``presets`` key is not sent to it anymore, and won't be taken into account if sent to the backend.
