- Kubeadm: added `show-join-command` as a new separate phase at the end of `kubeadm init`. You can skip printing the join information by using `kubeadm init --skip-phases=show-join-command`. Executing only this phase on demand will throw an error because the phase needs dependencies such as bootstrap tokens to be pre-populated.

- Azure virtual machine scale sets (VMSS) allow you to create and manage identical load balanced VMs that automatically increase or decrease based on demand or a set schedule.

### Pod resource metrics

On-demand metrics calculation is now available through `/metrics/resources`. [When enabled](

 You can continue to use code that depends on mutable selectors by calling
 the apps/v1beta1 API in this release, but you should start planning for code
 that does not depend on mutable selectors.

 - Extended Resources are fully-qualified resource names outside the
 `kubernetes.io` domain. Extended Resource quantities must be integers.

* The `PersistentVolumeLabel` admission controller is now disabled by default. If you depend on this feature (AWS/GCE) then ensure it is added to the `--enable-admission-plugins` flag on the kube-apiserver. ([#64326](https://github.com/kubernetes/kubernetes/pull/64326), [@andrewsykim](https://github.com/andrewsykim))

The merged fix enforces validation against the proxying address for a Node. In some cases, the fix can break clients that depend on the `nodes/proxy` subresource, specifically if a kubelet advertises a localhost or link-local address to the Kubernetes control plane. Configuring an egress proxy for egress to the cluster network can also mitigate this vulnerability.

- E2e.test and e2e_node.test: tests which depend on alpha or beta feature gates now have `Feature:Alpha` or `Feature:Beta` as Ginkgo labels. The inline text is `[Alpha]` or `[Beta]`, as before. ([#124350](https://github.com/kubernetes/kubernetes/pull/124350), [@pohly](https://github.com/pohly))...

semantics that replicas did prior to 1.7 ([#46669](https://github.com/kubernetes/kubernetes/pull/46669), [@kow3ns](https://github.com/kow3ns)).

* ControllerRevision type has been added for StatefulSet and DaemonSet history. Clients should not depend on the stability of this type as it may change, as necessary, in future releases to support StatefulSet and DaemonSet update and rollback. We enable this type as we do with beta features, because StatefulSet update and DaemonSet update are enabled....
