* [beta] A new `upgrade` subcommand allows you to automatically upgrade a self-hosted cluster created with kubeadm. ([#296](https://github.com/kubernetes/enhancements/issues/296), [@luxas](https://github.com/luxas))

- The in-tree GCE PD plugin `kubernetes.io/gce-pd` is now deprecated and will be removed in 1.21. Users that self-deploy Kubernetes on GCP should enable CSIMigration + CSIMigrationGCE features and install the GCE PD CSI Driver (https://github.com/kubernetes-sigs/gcp-compute-persistent-disk-csi-driver) to avoid disruption to existing Pod and PVC objects at that...

            or {@code combine.self} attributes to the children of the configuration element:</p>
            <ul>
            <li>{@code combine.children}: available values are {@code merge} (default) and {@code append},</li>

    when no certificates were pinned. This avoids an SSL failure in insecure
    “trust everyone” configurations, such as when talking to a development
    HTTPS server that has a self-signed certificate.

 *  Fix: Don't crash when finding the trust manager if the Play Services (GMS)
    security provider is installed.

- Kubeadm: deprecate self-hosting support. The experimental command "kubeadm alpha self-hosting" is now deprecated and will be removed in a future release. ([#95125](https://github.com/kubernetes/kubernetes/pull/95125), [@neolit123](https://github.com/neolit123)) [SIG Cluster Lifecycle]

    * or grant self-deletion permission explicitly:
        * `kubectl create clusterrole self-deleting-nodes --verb=delete --resource=nodes`
        * `kubectl create clusterrolebinding self-deleting-nodes --clusterrole=self-deleting-nodes --group=system:nodes`

* StatefulSet will now fill the `hostname` and `subdomain` fields if they're empty on existing Pods it owns. This allows it to self-correct the issue where StatefulSet Pod DNS entries disappear after upgrading to v1.7.x ([#48327](https://github.com/kubernetes/kubernetes/pull/48327)).
