Updating Airflow

This file documents any backwards-incompatible changes in Airflow and assists people when migrating to a new version.

Airflow 1.8

Changes to Behavior

New DAGs are paused by default

Previously, new DAGs would be scheduled immediately. To retain the old behavior, add this to airflow.cfg:

[core]
dags_are_paused_at_creation = False

Deprecated Features

These features are marked for deprecation. They may still work (and raise a DeprecationWarning), but are no longer supported and will be removed entirely in Airflow 2.0

Operators no longer accept arbitrary arguments

Previously, Operator.__init__() accepted any arguments (either positional *args or keyword **kwargs) without complaint. Now, invalid arguments will be rejected.
