## Metrics Changes

### Added metrics

- The metric `kube_proxy_sync_proxy_rules_last_timestamp_seconds` is now available, indicating the last time that kube-proxy successfully applied proxying rules. ([#74027](https://github.com/kubernetes/kubernetes/pull/74027), [@squeed](https://github.com/squeed))

* Fixes an issue where the resourceVersion of an object in a DELETE watch event was not the resourceVersion of the delete itself, but of the last update to the object. This could disrupt the ability of clients clients to re-establish watches properly. ([#58547](https://github.com/kubernetes/kubernetes/pull/58547), [@liggitt](https://github.com/liggitt))

### Feature

- Kubeadm: generate CA certificates with a start time that is offset 5 minutes in the past relative to the current system time to workaround cases of clock desync.

	// the last thing to check is pod spec equality.  If the pod specs are equal, then we can simply return the errors we have
	// so far and save the cost of a deep copy.

	// and doesn't spam the readiness endpoint too much
	//
	// If the probe is disabled, it is recommended to have delay=1s,period=2s,failureThreshold=30.
	// This ensures the startup is reasonable fast (polling every 2s). 1s delay is used since the startup is not often ready instantly.
