    * kubeadm - Ensure that the etcd certificates are generated using a proper CN
    * kubeadm - Update generated etcd peer certificate to include localhost addresses for the default configuration.
    * kubeadm - Increase the manifest update timeout to make upgrades a bit more reliable.

- Kubeadm: during execution of the "check expiration" command, treat the etcd CA as external if there is a missing etcd CA key file (etcd/ca.key) and perform the proper validation on certificates signed by the etcd CA. Additionally, make sure that the CA for all entries in the output table is included - for both certificates on disk and in kubeconfig files.

in kubectl, as well as finishing [kubectl diff which is based on server-side dry-run feature](https://kubernetes.io/docs/concepts/overview/working-with-objects/object-management/#how-to-create-objects). We’ve continued separating kubectl code to prepare for extraction out of main repository. Finally, thanks to the awesome support and feedback from community we’ve managed to promote the new [plugin mechanism to Beta](https://kubernetes.io/docs/tasks/extend-kubectl/kubectl-plugins/).

* addon-resizer flapping behavior was removed. ([#46850](https://github.com/kubernetes/kubernetes/pull/46850), [@x13n](https://github.com/x13n))
* Change default `httpGet` probe `User-Agent` to `kube-probe/<version major.minor>` if none specified, overriding the default Go `User-Agent`. ([#47729](https://github.com/kubernetes/kubernetes/pull/47729), [@paultyng](https://github.com/paultyng))

* Adds optional group and version information to the discovery interface, so that if an endpoint uses non-default values, the proper value of "kind" can be determined. Scale is a common example. ([#49971](https://github.com/kubernetes/kubernetes/pull/49971), [@deads2k](https://github.com/deads2k))

- `kubeadm`: Started using a named port `probe-port` for all probes in the static pod manifests generated by `kubeadm` for the `kube-apiserver`, `kube-controller-manager`, `kube-scheduler`, and related components. If probe port values were previously patched using `kubeadm` patches, the corresponding named port under the container’s `ports` field must now also be patched. ([#1327...

unschedulable pods, scale up is required and cloud provider is slow to set up networking for new nodes.
Anyway, the cluster should get back to the proper size after 10 min.
