- Kube-proxy in iptables mode now has separate `sync_full_proxy_rules_duration_seconds`
  and `sync_partial_proxy_rules_duration_seconds` (in addition to the existing
  `sync_proxy_rules_duration_seconds`), to give better information about how long
  each sync type is taking, rather than only giving a weighted average of the two

- Fixed bug in CPUManager with race on container map access ([#97427](https://github.com/kubernetes/kubernetes/pull/97427), [@klueska](https://github.com/klueska)) [SIG Node]

- `reflector_watches_total`

### Deprecated metrics

- `rest_client_request_latency_seconds` -> `rest_client_request_duration_seconds`
- `apiserver_proxy_tunnel_sync_latency_secs` -> `apiserver_proxy_tunnel_sync_duration_seconds`
- `scheduler_scheduling_latency_seconds` -> `scheduler_scheduling_duration_seconds`
- `kubelet_pod_worker_latency_microseconds` -> `kubelet_pod_worker_duration_seconds`

- In "large" clusters, kube-proxy in iptables mode will now sometimes
  leave unused rules in iptables for a while (up to `--iptables-sync-period`)
  before deleting them. This improves performance by not requiring it to
  check for stale rules on every sync. (In smaller clusters, it will still
  remove unused rules immediately once they are no longer used.)

* Provide kubernetes-controller-manager flags to control volume attach/detach reconciler sync.  The duration of the syncs can be controlled, and the syncs can be shut off as well. ([#39551](https://github.com/kubernetes/kubernetes/pull/39551), [@chrislovecnm](https://github.com/chrislovecnm))

- GCE Internal LoadBalancer sync loop will now release the ILB IP address upon sync failure. An error in ILB forwarding rule creation will no longer leak IP addresses. ([#97740](https://github.com/kubernetes/kubernetes/pull/97740), [@prameshj](https://github.com/prameshj)) [SIG Cloud Provider and Network]...

*   Added the concurrent service sync flag to the Cloud Controller Manager to allow changing the number of workers. (`--concurrent-service-syncs`) ([#55561](https://github.com/kubernetes/kubernetes/pull/55561),[ @jhorwit2](https://github.com/jhorwit2))
