## Airflow Master
+### Rename policy to task_policy
+
+Because Airflow introduced DAG level policy (`dag_policy`) we decided to
rename existing `policy`
+function to `task_policy` to make the distinction more profound and avoid any
confusion.
+
+Users using cluster policy need to rename their `policy` functions in
`airflow_local_settings.py`
+to `task_policy`.
+
Review comment:
I think we should deprecate it rather than remove.

Review comment:
Here we should check if 'policy' is defined and run it as well but with
deprecation warning.
