===================
Fixed
-----
- Add default value for ``FLOW_PROCESSES_ALLOW_LIST`` and
``FLOW_PROCESSES_IGNORE_LIST`` in case of missing settings.
- User defined slug must not be changed
- Raise ``ValidationError`` when trying to get non-existent ``AnnotationField``
- Propagate arguments to parent save method in ``BaseCollection`` model
Added
-----
- Add ``extend_lock`` method to redis cache in listener
- Add extending processing lock task to the listener
- Add ``FLOW_KUBERNETES_PULL_POLICY`` setting to set the image pull policy in
``Kubernetes`` instead of using ``Always``
Changed
-------
- Wrap listener command processing in a transaction
- Return ``False`` when ``has_perm`` is called with ``obj`` set no None, since
object level permissions are granted using Django ``ModelBackend``
authentication backend
- Use ``keys`` instead of ``scan_iter`` in ``clear`` method of ``redis`` cache,
since ``scan_iter`` is much slower
- Do not allow deleting annotation field if annotation values are present
