- Migrated the `Deployment` controller (within `kube-controller-manager`) to use [contextual logging](https://k8s.io/docs/concepts/cluster-administration/system-logs/#contextual-logging) ([#113525](https://github.com/kubernetes/kubernetes/pull/113525), [@249043822](https...

- Seccomp support has graduated to GA. A new `seccompProfile` field is added...

- Pods which set `hostNetwork: true` and declare ports, get the `hostPort` field set automatically. Previously this would happen in the PodTemplate of a Deployment, DaemonSet or other workload API.  Now `hostPort` will only be set when an actual Pod is being created.  If this presents a problem, setting the feature gate "DefaultHostNetworkHostPortsInPodTemplates" to true will revert this behavior.  Please...

  select the same set of Pods, scaling now will be disabled for those HPAs with
  the reason `AmbiguousSelector`. This change also covers a case when multiple HPAs
  point to the same deployment.'

- 'Pod Security admission: the pod-security `warn` level will now default to
  the `enforce` level.'

- Fix kubectl annotate error when local=true is set ([#86952](https://github.com/kubernetes/kubernetes/pull/86952), [@zhouya0](https://github.com/zhouya0)) [SIG CLI]
- Fix kubectl create deployment image name ([#86636](https://github.com/kubernetes/kubernetes/pull/86636), [@zhouya0](https://github.com/zhouya0)) [SIG CLI]

- The deprecated kube-controller-manager flag '--deployment-controller-sync-period' has been removed, it is not used by the deployment controller. ([#107178](https://github.com/kubernetes/kubernetes/pull/107178), [@SataQiu](https://github.com/SataQiu))

### Documentation

- Added descriptions and examples for the situation of using `kubectl rollout restart` without specifying a particular deployment. ([#120118](https://github.com/kubernetes/kubernetes/pull/120118), [@Ithrael](https://github.com/Ithrael))

- Fixing a bug that was preventing updates from 1.10 to 1.11

The external cloud provider was established and reached feature parity with in-tree, and we expect to stabilize it and have it as preferred deployment model by 1.13. We are also getting started on externalizing the vSphere volume functionalities in a CSI plugin to fully reproduce the current in-tree storage functionality.

- kubeadm

  - The CoreDNS Deployment now checks readiness via the `ready` plugin.
  - The `proxy` plugin has been deprecated. The `forward` plugin is to be used instead.
  - `kubernetes` plugin removes the `resyncperiod` option.

  - PodSecurityPolicy resources will no longer be served from `extensions/v1beta1` in v1.16. Migrate to the `policy/v1beta1` API, available since v1.10. Existing persisted data can be retrieved via the `policy/v1beta1` API.
  - DaemonSet, Deployment, and ReplicaSet resources will no longer be served from `extensions/v1beta1`, `apps/v1beta1`, or `apps/v1beta2` in v1.16. Migrate to the `apps/v1` API, available since v1.9. Existing persisted data can be retrieved via the `apps/v1` API.
