> If a Mesos agent is upgraded to provide reliable feedback for operations on agent default resources and then later downgraded, the master may possess in-memory state related to operations requesting feedback which should be cleaned up. We should update the master to detect downgraded agents and clean up appropriately.
> This ticket does not include sending best-effort feedback to schedulers for operations on downgraded agents.
> The upgrade documentation should also be updated with a note about the impact of downgrades on operation feedback.
