#### **API Server**

* kube-apiserver: the default `--endpoint-reconciler-type` is now `lease`. The `master-count` endpoint reconciler type is deprecated and will be removed in 1.13. ([#63383](https://github.com/kubernetes/kubernetes/pull/63383), [@liggitt](https://github.com/liggitt))

- Kube-apiserver: the `--master-count` flag and `--endpoint-reconciler-type=master-count` reconciler are deprecated in favor of the lease reconciler ([#108062](https://github.com/kubernetes/kubernetes/pull/108062), [@aojea](https://github.com/aojea))

    * and  DefaultStorageClass admission plugin can be used to preserve similar behavior of Kubernetes cluster,
    * see https://kubernetes.io/docs/user-guide/persistent-volumes/#class-1 for details.
* Reduce verbosity of volume reconciler when attaching volumes ([#36900](https://github.com/kubernetes/kubernetes/pull/36900), [@codablock](https://github.com/codablock))

- New staging repo has been created for the `EndpointSlice` reconciler. ([#118953](https://github.com/kubernetes/kubernetes/pull/118953), [@mskrocki](https://github.com/mskrocki))

### Bug or Regression

- Fix endpoint reconciler not being able to delete the apiserver lease on shutdown ([#114153](https://github.com/kubernetes/kubernetes/pull/114153), [@aojea](https://github.com/aojea)) [SIG API Machinery]

    * - clusters moving from IPv4 to duakstack will require no changes
    * - clusters moving from IPv6 (while not seen in the wild, we can not rule out their existence) to dualstack will require deleting backend pools (the reconciler will take care of creating correct backendpools)
* Promotes VolumePVCDataSource (Cloning) feature to beta for 1.16 release  ([#81792](https://github.com/kubernetes/kubernetes/pull/81792), [@j-griffith](https://github.com/j-griffith))
