- Remove storage metrics `storage_operation_errors_total`, since we already have `storage_operation_status_count`.And add new field `status` for `storage_operation_duration_seconds`, so that we can know about all status storage operation latency.

  The incorrect cost was evident when the result of a function was used in subsequent operations. ([#119809](https://github.com/kubernetes/kubernetes/pull/119809), [@jpbetz](https://github.com/jpbetz)) [SIG API Machinery, Auth and Cloud Provider]

* Use separate client for leader election in scheduler to avoid starving leader election by regular scheduler operations. ([#53793](https://github.com/kubernetes/kubernetes/pull/53793), [@wojtek-t](https://github.com/wojtek-t))

containers are only an alpha feature. To allow using CSI storage on Windows nodes, [CSIProxy](https://github.com/kubernetes-csi/csi-proxy) enables CSI node plugins to be deployed as unprivileged pods, using the proxy to perform privileged storage operations on the node.

Another feature moving to GA in v1.22 is CSI Service Account Token support. This feature allows CSI drivers to use pods' [bound service account tokens](https://kubernetes.io/docs/reference/access-authn-authz/service-ac...

- Support more than 100 disk mounts on Windows ([#105673](https://github.com/kubernetes/kubernetes/pull/105673), [@andyzhangx](https://github.com/andyzhangx))
- Support using negative array index in JSON patch replace operations. ([#105896](https://github.com/kubernetes/kubernetes/pull/105896), [@zqzten](https://github.com/zqzten))

- Updated the default API priority-and-fairness config to avoid endpoint/configmaps operations from controller-manager to all match leader-election priority level. ([#106725](https://github.com/kubernetes/kubernetes/pull/106725), [@wojtek-t](https://github.com/wojtek-t))

- [Conformance tests](https://github.com/kubernetes/kubernetes/pull/108592) added support for Windows
- New repository created for [Windows Operational Readiness](https://github.com/kubernetes-sigs/windows-operational-readiness)

### Moved container registry service from k8s.gcr.io to registry.k8s.io

   ([#122558](https://github.com/kubernetes/kubernetes/pull/122558), [@linxiulei](https://github.com/linxiulei))
- Fixed CEL estimated cost for expressions that perform operations on the result of `map()` operations (e.g., `.map(...).exists(...)` ) to have the correct estimated cost instead of an unbounded cost.
