* Added warning msg for `kubectl get` ([#28352](https://github.com/kubernetes/kubernetes/pull/28352), [@vefimova](https://github.com/vefimova))
* Removed support for HPA in extensions client. ([#30504](https://github.com/kubernetes/kubernetes/pull/30504), [@piosz](https://github.com/piosz))
* Implement DisruptionController. ([#25921](https://github.com/kubernetes/kubernetes/pull/25921), [@mml](https://github.com/mml))

**Who is affected?**

Only Kubernetes 1.5.0-1.5.4 installations that do all of the following:
* Enable the PodSecurityPolicy API (which is not enabled by default):
  * `--runtime-config=extensions/v1beta1/podsecuritypolicy=true`
* Enable the PodSecurityPolicy admission plugin (which is not enabled by default):
  * `--admission-control=...,PodSecurityPolicy,...`

### Network

In v1.9 SIG Network has implemented alpha support for IPv6, and alpha support for CoreDNS as a drop-in replacement for kube-dns. Additionally, SIG Network has begun the deprecation process for the extensions/v1beta1 NetworkPolicy API in favor of the networking.k8s.io/v1 equivalent.

### Apps

- The `.spec.rollbackTo` field of the Deployment kind is deprecated in `extensions/v1beta1`.

- The `kubernetes.io/created-by` annotation is deprecated and will be removed in version 1.9.

* kube-apiserver now includes all registered API groups in discovery, including registered extension API group/versions for unavailable extension API servers. ([#66932](https://github.com/kubernetes/kubernetes/pull/66932), [@nilebox](https://github.com/nilebox))



# v1.10.7

- `kubectl get ingress` now prefers the `networking.k8s.io/v1` over `extensions/v1beta1` (deprecated since v1.14). To explicitly request the deprecated version, use `kubectl get ingress.v1beta1.extensions`.
