#### Storage
- A node that uses a CSI raw block volume needs to be drained before kubelet can be upgraded to 1.17. ([#74026](https://github.com/kubernetes/kubernetes/pull/74026), [@mkimuram](https://github.com/mkimuram))

#### Windows

- kube-controller-manager currently needs a writable `--cert-dir` (default is `/var/run/kubernetes`) for generating self-signed certificates, when no `--tls-cert-file` or `--tls-private-key-file` are provided.

* Action required: validation rule on metadata.initializers.pending[x].name is tightened. The initializer name needs to contain at least three segments separated by dots. If you create objects with pending initializers, (i.e., not relying on apiserver adding pending initializers according to initializerconfiguration), you need to update the initializer name in existing...

- When using `kubectl replace` (or the equivalent API call) on a Service, the caller no longer needs to do a read-modify-write cycle to fetch the allocated values for `.spec.clusterIP` and `.spec.ports[].nodePort`.  Instead the API server will automatically carry these forward from the original object when the new object does not specify them. ([...

- Online volume expansion (ExpandInUsePersistentVolumes) is now a beta feature. As such, it is...

* kube-proxy needs to be configured to override hostname in some environments. ([#857](https://github.com/kubernetes/kubeadm/issues/857), [@detiber](https://github.com/detiber))

* Bugfix: OpenAPI models may not get group-version-kind extension if kubernetes is vendored in another project (e.g. minikube). Kubectl 1.8 needs this extension to work with those projects. ([#53152](https://github.com/kubernetes/kubernetes/pull/53152), [@mbohlool](https://github.com/mbohlool))

    *    That means, now  VCP can handle cases where user changes VM inventory name.
    * - VCP can handle cases where VM migrates to other ESXi cluster or datacenter or vCenter.
    * The only requirement is the shared storage. VCP needs shared storage on all Node VMs.
* The RBAC bootstrapping policy now allows authenticated users to create selfsubjectrulesreviews. ([#56095](https://github.com/kubernetes/kubernetes/pull/56095), [@ericchiang](https://github.com/ericchiang))
