- `KMSv1` is deprecated and will only receive security updates going forward. Use `KMSv2` instead. In a future release, Set `--feature-gates=KMSv1=true` to use the deprecated KMSv1 feature. ([#119007](https://github.com/kubernetes/kubernetes/pull/119007), [@aramase](https://github.com/aramase))

- the `ClusterStatus` struct present in the kubeadm-config ConfigMap is deprecated and will be removed in a future version. It is going to be maintained by kubeadm until it gets removed. The same information can be found on `etcd` and `kube-apiserver` pod annotations, `kubeadm.kubernetes.io/etcd.advertise-client-urls` and `kubeadm.kubernetes.io/kube-apiserver.advertise-address.endpoint`...

deployed using the `federation/deploy/deploy.sh` script. This script does not depend on any of the development environment shell library/scripts. This is an alternative to the current `federation-up.sh`/`federation-down.sh` scripts. Both the scripts are going to co-exist in this release, but the `federation-up.sh`/`federation-down.sh` scripts might be removed in a future release in favor of `federation/deploy/deploy.sh` script.

- Removed legacy cloud provider integration code (undoing a previous reverted commit). ([#124886](https://github.com/kubernetes/kubernetes/pull/124886), [@carlory](https://github.com/carlory)) [SIG Cloud Provider and Release]

### API Change

  * deleteOptions.orphanDependents is going to be deprecated in 1.7. Please use deleteOptions.propagationPolicy instead.

### kubeadm

* Support for passing unknown provider names to the E2E test binaries is going to be deprecated. Use `--provider=skeleton` (no ssh access) or `--provider=local` (local cluster with ssh) instead. ([#70141](https://github.com/kubernetes/kubernetes/pull/70141), [@pohly](https://github.com/pohly))

## **Notable Features**

* fixed foreground deletion of podtemplates ([#60683](https://github.com/kubernetes/kubernetes/pull/60683), [@nilebox](https://github.com/nilebox))
* Timeout docker queries to prevent node going NotReady indefinitely. ([#56967](https://github.com/kubernetes/kubernetes/pull/56967), [@jsravn](https://github.com/jsravn))

* ReplicationController now shares its underlying controller implementation with ReplicaSet to reduce the maintenance burden going forward. However, they are still separate resources and there should be no externally visible effects from this change.
