+## 1.0.4 - 2019-01-01
+
+### Changes
+* Use the [Orchestrator API](https://github.com/github/orchestrator/blob/master/docs/using-the-web-api.md)
+to call `begin-downtime` before running `PlannedReparentShard` in the `preStopHook`, to make sure that Orchestrator
+doesn't try to run an external failover while Vitess is reparenting. When it is complete, it calls `end-downtime`.
+Also call `forget` on the instance after calling `vtctlclient DeleteTablet`. It will be rediscovered if/when
+the tablet comes back up. This eliminates most possible race conditions that could cause split brain.
