SIG Storage made a lot of progress in the 1.18 release.
In particular, the following storage features are moving to GA in Kubernetes 1.18:
- Raw Block Support: Allow volumes to be surfaced as block devices inside containers instead of just mounted filesystems.
- Volume Cloning: Duplicate a PersistentVolumeClaim and underlying storage volume using the Kubernetes API via CSI.

- For raw block CSI volumes on Kubernetes, kubelet was incorrectly calling CSI NodeStageVolume for every single "map" (i.e. raw block "mount") operation for a volume already attached to the node. This PR ensures it is only called once per volume per node. ([#112403](https://github.com/kubernetes/kubernetes/pull/112403),...

  
  The CSI Migration feature for vSphere Volume also requires minimum vSphere vCenter/ESXi Version to be 7.0u1 and minimum HW Version to be VM version 15.
  

* The error handling behavior of `pkg/client/restclient.Result` has changed.  Calls to `Result.Raw()` will no longer parse the body, although they will still return errors that react to `pkg/api/errors.Is*()` as in previous releases.  Callers of `Get()` and `Into()` will continue to receive errors that are parsed from the body if the kind and apiVersion...

### Bug or Regression

- Allow deletion of pods that use raw block volumes on node reboot ([#122211](https://github.com/kubernetes/kubernetes/pull/122211), [@gnufied](https://github.com/gnufied)) [SIG Node and Storage]

        TPUs. See
        [usage guide](https://www.tensorflow.org/guide/keras/mixed_precision).
    *   Introduced the `TextVectorization` layer, which takes as input raw
        strings and takes care of text standardization, tokenization, n-gram
        generation, and vocabulary indexing. See this

- `kubectl create|delete|get|replace --raw` commands now honored the server root paths specified in the kubeconfig file. ([#131165](https://github.com/kubernetes/kubernetes/pull/131165), [@liggitt](https://github.com/liggitt))

### Other (Cleanup or Flake)

### SIG Storage

* AWS EBS, Azure Disk, GCE PD and Ceph RBD volume plugins now support dynamic provisioning of raw block volumes. ([#64447](https://github.com/kubernetes/kubernetes/pull/64447), [@jsafrane](https://github.com/jsafrane))

- DRA: ResourceClaim and PodSchedulingContext status updates no longer allow changing object meta data. ([#123730](https://github.com/kubernetes/kubernetes/pull/123730), [@pohly](https://github.com/pohly))
- Enabled deletion of pods that use raw block volumes on node reboot. ([#122211](https://github.com/kubernetes/kubernetes/pull/122211), [@gnufied](https://github.com/gnufied))
