- Introducing new semantic for metric `volume_operation_total_seconds` to be the end to end latency of volume provisioning/deletion. Existing metric "storage_operation_duration_seconds" will remain untouched, however it is exposed to the following potential issues:

- Fixed a bug that a pod may remain unscheduled if any PreFilter plugin returns nodes that do not exist. ([#124764](https://github.com/kubernetes/kubernetes/pull/124764), [@chengjoey](https://github.com/chengjoey)) [SIG Scheduling and Testing]

* fix formatAndMount func issue on Windows ([#63248](https://github.com/kubernetes/kubernetes/pull/63248), [@andyzhangx](https://github.com/andyzhangx))
* Fixes an issue where Portworx PVCs remain in pending state when created using a StorageClass with empty parameters ([#64895](https://github.com/kubernetes/kubernetes/pull/64895), [@harsh-px](https://github.com/harsh-px))

- Scheduler framework permit plugins now run at the end of the scheduling cycle, after reserve plugins. Waiting on permit will remain in the beginning of the binding cycle. ([#88199](https://github.com/kubernetes/kubernetes/pull/88199), [@mateuszlitwin](https://github.com/mateuszlitwin)) [SIG Scheduling]

  - By default, injected tokens are given an extended lifetime so they remain valid even after a new refreshed token is provided. The metric `serviceaccount_stale_tokens_total` can be used to monitor for workloads that are depending on the extended lifetime and are continuing to use tokens even after a refreshed token is provided...

If the type is omitted, the constants take the
individual types of the corresponding expressions.
If the expression values are untyped <a href="#Constants">constants</a>,
the declared constants remain untyped and the constant identifiers
denote the constant values. For instance, if the expression is a
floating-point literal, the constant identifier denotes a floating-point

  This behavior will change to:
  - Services that have been set  IPFamilyPolicy = PreferDualstack will not be upgraded when the service object is updated. User can still change policy, type etc and existing behaviors remain the same.
