* In case StorageObjectInUse feature is disabled and Persistent Volume (PV) or Persistent Volume Claim (PVC) contains a finalizer and the PV or PVC is deleted it is not automatically removed from the system.

    *   Change `node.alpha.kubernetes.io/unreachable` to  `node.kubernetes.io/unreachable`
*   The `node.kubernetes.io/memory-pressure` taint now respects the configured whitelist.  To use it, you must add it to the whitelist.([#55251](https://github.com/kubernetes/kubernetes/pull/55251),[ @deads2k](https://github.com/deads2k))
*   Refactor kube-scheduler configuration ([#52428](https://github.com/kubernetes/kubernetes/pull/52428))

  Depending on the value returned from QueueingHintFn, the scheduling queue changes how it queues each Pod:
  - if more than one QueueingHintFn returns QueueImmediately, it queues Pod to activeQ.

* StatefulSet: The deprecated `pod.alpha.kubernetes.io/initialized` annotation for interrupting StatefulSet Pod management is now ignored. If you were setting it to `true` or leaving it unset, no action is required. However, if you were setting it to `false`, be aware that previously-dormant StatefulSets may become active after upgrading.

PodSecurityPolicy was initially [deprecated in v1.21](/blog/2021/04/06/podsecuritypolicy-deprecation-past-present-and-future/), and with the release of v1.25, it has been removed. The updates required to improve its usability would have introduced breaking changes, so it became necessary to remove it in favor of a more friendly replacement. That replacement is [Pod Security Admission](/docs/concepts/security/pod-security-admission/), which graduates to Stable with this release....

- The feature gate was mentioned as `csiMigrationRBD` where it should have been `CSIMigrationRBD` to be in parity with other migration plugins. This release correct the same and keep it as `CSIMigrationRBD`.
