- Non-graceful node shutdown handling is enabled for stateful workload failovers ([#108486](https://github.com/kubernetes/kubernetes/pull/108486), [@sonasingh46](https://github.com/sonasingh46))

   The `read_vs_write_current_requests` metric histogram is adjusted, in the case of using API Priority and Fairness instead of max-in-flight, to divide by the relevant limit: sum of queue capacities for waiting requests, sum of seat limits for executing requests. ([#110164](https://github.com/kubernetes/kubernetes/pull/110164), [@MikeSpreitzer](https://github.com/MikeSpreitzer))

- Fixed `kubectl explain` to show enum for field types if they were defined. ([#123023](https://github.com/kubernetes/kubernetes/pull/123023), [@ah8ad3](https://github.com/ah8ad3))

- CEL cost estimator no longer treats enums as unbounded strings when determining its length. Instead, the length is set to the longest possible enum value. ([#121085](https://github.com/kubernetes/kubernetes/pull/121085), [@jiahuif](https://github.com/jiahuif)) [SIG API Machinery]

- `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))

- Removed `resizeStatus` enum from `pvc.Status` and replaced with `AllocatedResourceStatus`. ([#116335](https://github.com/kubernetes/kubernetes/pull/116335), [@gnufied](https://github.com/gnufied)) [SIG API Machinery, Apps, Auth, Node, Storage and Testing]
