- 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]

- `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`,

- 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...

* Action required: validation rule on metadata.initializers.pending[x].name is tightened. The initializer name needs to contain at least three segments separated by dots. If you create objects with pending initializers, (i.e., not relying on apiserver adding pending initializers according to initializerconfiguration), you need to update the initializer name in existing objects and in configuration files to comply to...
