  Avoid unnecessary GCE API calls when adding IP alises or reflecting them in Node object in GCE cloud provider. ([#96864](https://github.com/kubernetes/kubernetes/pull/96864), [@tosi3k](https://github.com/tosi3k)) [SIG Apps, Cloud Provider and Network]

- 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...

* Fix VMWare VM freezing bug by reverting [#51066](https://github.com/kubernetes/kubernetes/pull/51066) ([#67825](https://github.com/kubernetes/kubernetes/pull/67825), [@nikopen](https://github.com/nikopen))

applied configuration. Removed fields which have no other owners are deleted from the live object, or reset to their default value if they have one. Safe ownership transfers, such as the transfer of a `replicas` field from a user to an HPA without resetting to the default value are documented in [Transferring Ownership](https://kubernetes.io/docs/reference/using-api/api-concepts/#transferring-ownership) ([#92661](https://github.com/kubernetes/kubernetes/pull/92661), [@jpbetz](https://github.com/jpbetz))...

Such an empty list is equivalent to the textual substitution of the
first preceding non-empty expression list and its type if any.

- Added support for CEL expressions to `v1alpha1 AuthorizationConfiguration` webhook `matchConditions`. ([#121223](https://github.com/kubernetes/kubernetes/pull/121223), [@ritazh](https://github.com/ritazh))
- Added support for projecting `certificates.k8s.io/v1alpha1` ClusterTrustBundle objects into pods. ([#113374](https://github.com/kubernetes/kubernetes/pull/113374), [@ahmedtd](https://github.com/ahmedtd))

* Changes secret, configMap, downwardAPI and projected volumes to mount read-only, instead of allowing applications to write data and then reverting it automatically. Until version 1.11, setting the feature gate ReadOnlyAPIDataVolumes=false will preserve the old behavior.
