- `kubeproxy_conntrack_reconciler_deleted_entries_total` metric can be used to track cumulative sum of conntrack flows cleared by reconciler. ([#130204](https://github.com/kubernetes/kubernetes/pull/130204), [@aroradaman](https://github.com/aroradaman))

- The scheduler no longer cleared the `nominatedNodeName` field for Pods. External components, such as Cluster Autoscaler and Karpenter, were responsible for managing this field when needed. ([#133276](https://github.com/kubernetes/kubernetes/pull/133276), [@macsko](https://github.com/macsko))...

- The helping message of commands which have sub-commands is now clearer and more instructive. It will show the full command instead of `kubectl <command> --help ...`
  

- Certain fields on  Service objects will be automatically cleared when changing the service's `type` to a mode that does not need those fields.  For example, changing from type=LoadBalancer to type=ClusterIP will clear the NodePort assignments, rather than forcing the user to clear them. ([#95196](https://githu...

- `kubectl prune v2`: Switched annotation from `contains-group-resources` to `contains-group-kinds`,

  the newer `apiVersion`. ([#116299](https://github.com/kubernetes/kubernetes/pull/116299), [@pohly](https://github.com/pohly))
- `volumes`: `resource.claims` is now cleared for PVC specs during create or update of a pod spec with inline PVC template or of a PVC because it has no effect. ([#115928](https://github.com/kubernetes/kubernetes/pull/115928), [@pohly](https://github.com/pohly))

### Feature

- Make PodSpec.Ports' description clearer on how this information is only informational and how it can be incorrect. ([#110564](https://github.com/kubernetes/kubernetes/pull/110564), [@j4m3s-s](https://github.com/j4m3s-s)) [SIG API Machinery, Network and Node]

* fix race condition issue for smb mount on windows ([#75371](https://github.com/kubernetes/kubernetes/pull/75371), [@andyzhangx](https://github.com/andyzhangx))
* UDP Service conntrack entries for ExternalIPs are now correctly cleared when endpoints are added  ([#75265](https://github.com/kubernetes/kubernetes/pull/75265), [@JacobTanenbaum](https://github.com/JacobTanenbaum))

- Fixed a bug that a pod's `.status.nominatedNodeName` is not cleared properly, and thus over-occupied system resources. ([#106816](https://github.com/kubernetes/kubernetes/pull/106816), [@Huang-Wei](https://github.com/Huang-Wei))
