   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.

- `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))
