- Remove storage metrics `storage_operation_errors_total`, since we already have `storage_operation_status_count`.And add new field `status` for `storage_operation_duration_seconds`, so that we can know about all status storage operation latency.

    * If your config files contains fields with wrong case, the config files will be now invalid.
* GCE: Fixes operation polling to adhere to the specified interval. Furthermore, operation errors are now returned instead of ignored. ([#64630](https://github.com/kubernetes/kubernetes/pull/64630), [@nicksardo](https://github.com/nicksardo))

* Fixes authentication problem faced during various vSphere operations. ([#57978](https://github.com/kubernetes/kubernetes/pull/57978), [@prashima](https://github.com/prashima))
* The getSubnetIDForLB() should return subnet id rather than net id. ([#58208](https://github.com/kubernetes/kubernetes/pull/58208), [@FengyunPan](https://github.com/FengyunPan))

- Apiserver adds two new metrics `etcd_requests_total` and `etcd_request_errors_total` that allow users to monitor requests to etcd storage, split by operation and resource type. ([#117222](https://github.com/kubernetes/kubernetes/pull/117222), [@iyear](https://github.com/iyear)) [SIG API Machinery]

- Number of errors reported to the metric `storage_operation_duration_seconds_count` for emptyDir decreased significantly because previously one error was reported for each projected volume created. ([#117022](https://github.com/kubernetes/kubernetes/pull/117022), [@mpatlasov](https://github.com/mpatlasov))...

- List operations against the API now return internal server errors instead of partially complete lists when a value cannot be transformed from storage. The updated behavior is consistent with all other operations that require transforming data from storage such as watch and get.

* Fix clustered datastore name to be absolute. ([#54438](https://github.com/kubernetes/kubernetes/pull/54438), [@pshahzeb](https://github.com/pshahzeb))
* Fix `kubeadm upgrade plan` for offline operation: ignore errors when trying to fetch latest versions from dl.k8s.io ([#54016](https://github.com/kubernetes/kubernetes/pull/54016), [@praseodym](https://github.com/praseodym))

      - `docker_operations` -> `docker_operations_total`
      - `docker_operations_latency_microseconds` -> `docker_operations_duration_seconds`
      - `docker_operations_errors` -> `docker_operations_errors_total`
      - `docker_operations_timeout` -> `docker_operations_timeout_total`
      - `network_plugin_operations_latency_microseconds` -> `network_plugin_operations_duration_seconds`

- You can now have different operation names for different storage operations. This still prevents two operations on same volume from happening concurrently but if the operation changes, it resets the exponential backoff.
