- `kube-proxy` nftables mode is now compatible with kernel `5.4`. ([#122296](https://github.com/kubernetes/kubernetes/pull/122296), [@tnqn](https://github.com/tnqn))
- Renamed Label cluster to `storage_cluster_id` for `apiserver_storage_size_bytes metric` ([#124283](https://github.com/kubernetes/kubernetes/pull/124283), [dims](https://github.com/dims))

### Other (Cleanup or Flake)

- For apiserver_storage_size_bytes metric, we are renaming the label for etcd to be "storage_cluster_id" instead of "cluster" to to reduce conflict and be very specific.
