For backwards compatibility, contrib operators, which currently push to XCOM by default, should be updated to activate XCOM explicitly, doing this way, other contrib operators will keep the current behavior of not using XCOM. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
