- Added `apiserver_longrunning_requests` metric to replace the soon to be deprecated `apiserver_longrunning_gauge` metric. ([#103799](https://github.com/kubernetes/kubernetes/pull/103799), [@jyz0309](https://github.com/jyz0309))
- Controller-manager: the following flags have no effect and would be removed in v1.24:

- Introduction of a new "sync_proxy_rules_no_local_endpoints_total" proxy metric. This metric represents the number of services with no internal endpoints. The "traffic_policy" label will contain both "internal" or "external". ([#108930](https://github.com/kubernetes/kubernetes/pull/108930), [@MaxRenaud](https://github.com/MaxRenaud))...

- Fix etcd_object_counts metric reported by kube-apiserver ([#94819](https://github.com/kubernetes/kubernetes/pull/94819), [@tkashem](https://github.com/tkashem)) [SIG API Machinery]
