Volumes (SMB 2.1 and 3.0) into a Pod. See [example](https://github.com/kubernetes/kubernetes/blob/release-1.2/examples/azure_file/README.md) for details.
  * Logs usage and root filesystem usage of a container, volumes usage of a pod and node disk usage are exposed through Kubelet new metrics API.

### Experimental Features

  * Dynamic Provisioning of PersistentVolumes: Kubernetes previously required all

### Bug or Regression

- Fix: delete non existing Azure disk issue ([#107406](https://github.com/kubernetes/kubernetes/pull/107406), [@andyzhangx](https://github.com/andyzhangx)) [SIG Cloud Provider]

		// https://en.wikipedia.org/wiki/Copy_protection so the incoming stream
		// is always going to be in-memory as we cannot re-read from what we
		// wrote to disk - since that amounts to "copying" from a "copy"
		// instead of "copying" from source, we need the stream to be seekable
		// to ensure that we can make fan-out calls concurrently.

### Bug or Regression

- Fixed PersistentolumeLabel providing wrong topology labels to Azure Disk PersistentVolumes when the external Azure cloud provider is used. ([#124528](https://github.com/kubernetes/kubernetes/pull/124528), [@jsafrane](https://github.com/jsafrane)) [SIG Cloud Provider]

### Bug or Regression

- Add `/sys/devices/virtual/powercap` to default masked paths. It avoids the potential security risk that the ability to read these files may offer a power-based sidechannel attack against any workloads running on the same kernel. ([#125970](https://github.com/kubernetes/kubernetes/pull/125970), [@carlory](https://github.com/carlory)) [SIG Node]

- Kubeadm: during the validation of existing kubeconfig files on disk, handle cases where the "ca.crt" is a bundle and has intermediate certificates. Find a common trust anchor between the "ca.crt" bundle and the CA in the existing kubeconfig on disk instead of treating "ca.crt" as a file containing a single CA.
