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.

        * Supplemental Groups
        * FSGroup - a special supplemental group
        * SELinux options
     * If a pod defines an FSGroup, that Pod’s system (emptyDir, secret, configMap,
etc) volumes and block-device volumes will be owned by the FSGroup, and each
container in the pod will run with the FSGroup as a supplemental group
  * Volumes that support SELinux labelling are now automatically relabeled with the

  these are intended for use in documentation, so please make it clear what
  you have done, and only do this where the benefit clearly outweighs the
  decrease in consistency.
* Note that Javadoc and block comments i.e. `/* ... */` are not formatted,
  but line comments i.e `// ...` are.
* Negative boolean expressions must use the form `foo == false` instead of
  `!foo` for better readability of the code. This is enforced via

- Switch to VM Update call in attach/detach disk operation, original CreateOrUpdate call may lead to orphaned VMs or blocked resources ([#81208](https://github.com/kubernetes/kubernetes/pull/81208), [@andyzhangx](https://github.com/andyzhangx))

- When the `StrictIPCIDRValidation` feature gate is enabled, Kubernetes will be
  slightly stricter about what values will be accepted as IP addresses and network
  address ranges (“CIDR blocks”).
  
  In particular, octets within IPv4 addresses are not allowed to have any leading
  `0`s, and IPv4-mapped IPv6 values (e.g. `::ffff:192.168.0.1`) are forbidden.
