A new feature was enabled to improve the performance of the iptables mode of `kube-proxy` in large clusters. No action was required, however:
  
  1. If you experienced problems with Services not syncing to iptables correctly, you can disable the feature by passing `--feature-gates=MinimizeIPTablesRestore=false` to kube-proxy (and file a bug if this fixes it). (This might also be detected by seeing the value of kube-proxy's `sync_proxy_rules_iptables_partial_restore_failures_total` metric...

* GCE: provide an option to disable docker's live-restore on COS/ubuntu ([#55260](https://github.com/kubernetes/kubernetes/pull/55260), [@yujuhong](https://github.com/yujuhong))

- Prevent watch cache starvation by moving its watch to separate RPC and add a SeparateCacheWatchRPC feature flag to disable this behavior ([#123694](https://github.com/kubernetes/kubernetes/pull/123694), [@mengqiy](https://github.com/mengqiy)) [SIG API Machinery]

for resizing existing persistent volumes.

### NonPreemptingPriority to Stable

This feature adds [a new option to PriorityClasses](https://github.com/kubernetes/enhancements/issues/902),
which can enable or disable pod preemption.

### Storage Plugin Migration

There is work under way to [migrate the internals of in-tree storage plugins](https://github.com/kubernetes/enhancements/issues/625) to call out to CSI Plugins,

 - End-to-end testing has been migrated from Ginkgo v1 to v2.

- Added consistent vanity import to files and provided tooling for verifying and updating them. ([#120642](https://github.com/kubernetes/kubernetes/pull/120642), [@jcchavezs](https://github.com/jcchavezs))

`false` (it is enabled by default). An API server fronted by an L7 load balancer that already mitigates these http/2 attacks may choose to disable the kube-apiserver mitigation to avoid disrupting load balancer -> kube-apiserver connections if http/2 requests from multiple clients share the same backend connection. An API server on a private network may opt to disable the kube-apiserver mitigation to prevent performance regressions for unauthenticated clients. Authenticated requests rely on the fix in...

- API Server tracing root span name for opentelemetry is changed from `KubernetesAPI` to `HTTP GET`. ([#112545](https://github.com/kubernetes/kubernetes/pull/112545), [@dims](https://github.com/dims))
