### SIG OpenStack

- Fixed cloud-controller-manager crash when using OpenStack provider and PersistentVolume initializing controller   ([#70459](https://github.com/kubernetes/kubernetes/pull/70459), [@mvladev](https://github.com/mvladev))

### SIG Release

- Fixed missing `kubelet_volume_stats_*` metrics. ([#133890](https://github.com/kubernetes/kubernetes/pull/133890), [@huww98](https://github.com/huww98)) [SIG Instrumentation and Node]
- Fixed occasional schedule delays when a static `PersistentVolume` is created. ([#133929](https://github.com/kubernetes/kubernetes/pull/133929), [@huww98](https://github.com/huww98)) [SIG Scheduling and Storage]

#### Storage

* [stable] Mount options

  * The ability to specify mount options for volumes is moved from beta to stable.

  * A new `MountOptions` field in the `PersistentVolume` spec is available to specify mount options. This field replaces an annotation.

  * A new `MountOptions` field in the `StorageClass` spec allows configuration of mount options for dynamically provisioned volumes.

- If a pvc has an empty storageClassName, persistentvolume controller won't try to assign a default StorageClass ([#122704](https://github.com/kubernetes/kubernetes/pull/122704), [@carlory](https://github.com/carlory)) [SIG Apps and Storage]

- Fixed a bug that occurred when the hostname label of a node did not match the node name, pods bound to a PersistentVolume with `nodeAffinity` using the hostname may be scheduled to the wrong node or experience scheduling failures.
