* hyperkube

  * The hyperkube image has been slimmed down and no longer includes addon manifests and other various scripts. These were introduced for the now removed docker-multinode setup system. ([#44555](https://github.com/kubernetes/kubernetes/pull/44555), [@luxas](https://github.com/luxas))

- Output for the `ScalingReplicaSet` event has changed from:

## Known Issues

- There is a known issue [coredns/coredns#2629](https://github.com/coredns/coredns/issues/2629) in CoreDNS 1.3.1, wherein if the Kubernetes API shuts down while CoreDNS is connected, CoreDNS will crash. The issue is fixed in CoreDNS 1.4.0 in [coredns/coredns#2529](https://github.com/coredns/coredns/pull/2529).

- `MaxUnavailable` for `StatefulSets`, allows faster `RollingUpdate` by taking down more than 1 pod at a time.
  The number of pods you want to take down during a `RollingUpdate` is configurable using `maxUnavailable` parameter.
