```release-note:bug
autopilot: **(Enterprise Only)** Previously servers in other zones would not be promoted when all servers in a second zone had failed. Now the actual behavior matches the docs and autopilot will promote a healthy non-voter from any zone to replace failure of an entire zone.
```
```release-note:feature
autopilot: A new `/v1/operator/autopilot/state` HTTP API was created to give greater visibility into what autopilot is doing and how it has classified all the servers it is tracking.
```
```release-note:improvement
autopilot: **(Enterprise Only)** Autopilot now supports using both Redundancy Zones and Automated Upgrades together.
```
```release-note:breaking-change
raft: Raft protocol v3 is no longer supported. If currently using protocol v2 then an intermediate upgrade to a version supporting both protocols will be necessary (1.0.0 - 1.8.x) 
```
