- Made legacy watch calls (`ResourceVersion` = 0 or unset) that generate init-events weigh higher in `API Priority and Fairness (APF)` seat usage. Properly accounting for their cost protects the API server from CPU overload. Users might see increased throttling of such calls as a result.

    * - unready but creation and last readiness change timestamps are apart more than 10s (pods that have formerly been ready and so metrics are in at least some cases (pod becoming unready because of overload) very useful).
* The `kubectl patch` command no longer exits with exit code 1 when a redundant patch results in a no-op ([#66725](https://github.com/kubernetes/kubernetes/pull/66725), [@juanvallejo](https://github.com/juanvallejo))
