+  * A new `DRAINING` state has been added to Mesos agents. Once an agent is draining, all tasks running on that agent are gracefully
+    killed and no offers for that agent are sent to schedulers, preventing the launching of new tasks.
+    Operators can put an agent into `DRAINING` state by using the `DRAIN_AGENT` operator API call.
