- KEP-3857: Recursive Read-only (RRO) mounts: promote to GA ([#130116](https://github.com/kubernetes/kubernetes/pull/130116), [@AkihiroSuda](https://github.com/AkihiroSuda)) [SIG Apps, Node and Testing]

SIG Storage is also introducing the following new storage features as alpha in Kubernetes 1.18:
- Windows CSI Support: Enabling containerized CSI node plugins in Windows via new [CSIProxy](https://github.com/kubernetes-csi/csi-proxy)
- Recursive Volume Ownership OnRootMismatch Option: Add a new “OnRootMismatch” policy that can help shorten the mount time for volumes that require ownership change and have many directories and files.

### Other notable announcements

- Deprecated the following kubectl run flags, which are ignored if set: `--cascade`, `--filename`, `--force`, `--grace-period`, `--kustomize`, `--recursive`, `--timeout`, `--wait`. ([#112261](https://github.com/kubernetes/kubernetes/pull/112261), [@brianpursley](https://github.com/brianpursley))

- Kube-apiserver: jsonpath expressions with consecutive recursive descent operators are no longer evaluated for custom resource printer columns ([#93408](https://github.com/kubernetes/kubernetes/pull/93408), [@joelsmith](https://github.com/joelsmith)) [SIG API Machinery]

### Skip Volume Ownership change graduates to GA

The feature to configure volume permission and ownership change policy for Pods moved to GA in 1.23.
This allows users to skip recursive permission changes on mount and speeds up the pod start up time.
