Heads up. Apache Airflow github master <https://github.com/apache/incubator-airflow> is behind Apache Airflow master <https://git1-us-west.apache.org/repos/asf?p=incubator-airflow.git;a=summary> currently. I've opened a ticket to fix this -- currently, merges are not syncing back to master <https://github.com/apache/incubator-airflow>.
https://issues.apache.org/jira/browse/INFRA-16303 -s
