notatallshaw edited a comment on issue #6370: AIRFLOW-5701: Don't clear xcom explicitly before execution URL: https://github.com/apache/airflow/pull/6370#issuecomment-546647813 It should be worth noting where people are trying to get the last execution dates xcom value and are using `xcom_pull(key=key, include_prior_dates=True)` this will be a backwards compatibility break on retry if the push occurred before the failure of the task. I don't know how heavily that is relied on, most pushes are probably at the and of the task run. But worth noting maybe.
