* Fixed the webhook admission plugin so that webhook author could use the DNS name of the service as the CommonName when generating the server cert for the webhook.
    * Action required:

    * --alpha-endpoint-reconciler-type=(master-count, lease, none) (default
    * "master-count"). The original reconciler is 'master-count'. The 'lease'
    * reconciler uses the storageapi and a TTL to keep alive an endpoint within the
    * `kube-apiserver-endpoint` storage namespace. The 'none' reconciler is a noop
    * reconciler that does not do anything. This is useful for self-hosted

* Use "k8s.gcr.io" for container images rather than "gcr.io/google_containers".  This is just a redirect, for now, so should not impact anyone materially.   ([#54174](https://github.com/kubernetes/kubernetes/pull/54174), [@thockin](https://github.com/thockin))

Provider is expected to ship their own instance of this binary. Details for a Cloud Provider to create an instance of such a binary can be found [here](https://github.com/kubernetes/kubernetes/tree/master/staging/src/k8s.io/cloud-provider/sample).

Questions about the Cloud Controller Manager on a Managed Kubernetes solution should go to the relevant Cloud Provider. Questions about the Cloud Controller...

### kube-proxy
* **- Add tcp/udp userspace proxy support for Windows. ([#41487](https://github.com/kubernetes/kubernetes/pull/41487), [@anhowe](https://github.com/anhowe))**
* Add DNS suffix search list support in Windows kube-proxy. ([#41618](https://github.com/kubernetes/kubernetes/pull/41618), [@JiangtianLi](https://github.com/JiangtianLi))

- Cloud provider config CloudProviderBackoffMode has been removed since it won't be used anymore. ([#88463](https://github.com/kubernetes/kubernetes/pull/88463), [@feiskyer](https://github.com/feiskyer)) [SIG Cloud Provider]

The following PRs changed the API spec:
  * In the new v1alpha2 kubeadm Configuration API, the `.CloudProvider` and `.PrivilegedPods` fields don't exist anymore. Instead, you should use the out-of-tree cloud provider implementations, which are beta in v1.11.

#### Deployments
* [beta] Deployments uses a hashing collision avoidance mechanism that ensures new rollouts will not block on hashing collisions anymore. ([kubernetes/features#287](https://github.com/kubernetes/enhancements/issues/287))
