#### General Fixes and Reliability

- On compatible systems, a mounter's Unmount implementation is changed to not return an error when the specified target can be detected as not a mount point. On Linux, the behavior of detecting a mount point depends on `umount` command is validated when the mounter is created. Additionally, mount point checks will be skipped in CleanupMountPoint/CleanupMountWithForce if the mounter's Unmount having the changed behavior of not returning error when target is not a...

- AzureFile and CephFS use the new Mount library that prevents logging of sensitive mount options. ([#88684](https://github.com/kubernetes/kubernetes/pull/88684), [@saad-ali](https://github.com/saad-ali)) [SIG Storage]

- Use force unmount for NFS volumes if regular mount fails after 1 minute timeout ([#96844](https://github.com/kubernetes/kubernetes/pull/96844), [@gnufied](https://github.com/gnufied)) [SIG Storage]
- Use network.Interface.VirtualMachine.ID to get the binded VM

#### 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.
