- The client label for apiserver_request_count and apiserver_request_total now no-opts and merely records an empty string. ([#87673](https://github.com/kubernetes/kubernetes/pull/87673), [@logicalhan](https://github.com/logicalhan)) [SIG API Machinery, Instrumentation and Scalability]

  * Fix a bug where Kubelet does not ignore pod manifest files starting with dots ([#45111](https://github.com/kubernetes/kubernetes/pull/45111), [@dwradcliffe](https://github.com/dwradcliffe))

- `StatefulSet` names must be DNS labels, rather than subdomains. Any `StatefulSet`
  which took advantage of subdomain validation (by having dots in the name) can't
  possibly have worked, because we eventually set `pod.spec.hostname` from the `StatefulSetName`,

### Node Components
* Kubelet config should ignore file start with dots.

* Bump GCI to gci-stable-56-9000-84-2.

* [Action required] The validation rule for metadata.initializers.pending[x].name is tightened. The initializer name must contain at least three segments, separated by dots. You can create objects with pending initializers and not rely on the API server to add pending initializers according to `initializerConfiguration`. If you do so, update the initializer name in the existing objects and the configuration files to comply...

* Deployment will stop adding pod-template-hash labels/selector to ReplicaSets and Pods it adopts. Resources created by Deployments are not affected (will still have pod-template-hash labels/selector).

- Added `--disable-compression` flag to `kubectl` (default = false). When true, it opts out of response compression for all requests to the `apiserver`. This can help improve list call latencies significantly when client-server network bandwidth is ample (>30MB/s) or if the server is CPU-constrained. ([#112580](https://github.com/kub...
