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.

- Enhanced the daemonset sync logic to avoid a problem where pods are thought to be unavailable when the controller's clock is slower than the node's clock. ([#77208](https://github.com/kubernetes/kubernetes/pull/77208), [@DaiHao](https://github.com/DaiHao))

- 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]
