* Adds optional group and version information to the discovery interface, so that if an endpoint uses non-default values, the proper value of "kind" can be determined. Scale is a common example. ([#49971](https://github.com/kubernetes/kubernetes/pull/49971), [@deads2k](https://github.com/deads2k))

- `kubeadm`: Started using a named port `probe-port` for all probes in the static pod manifests generated by `kubeadm` for the `kube-apiserver`, `kube-controller-manager`, `kube-scheduler`, and related components. If probe port values were previously patched using `kubeadm` patches, the corresponding named port under the container’s `ports` field must now also be patched. ([#1327...

unschedulable pods, scale up is required and cloud provider is slow to set up networking for new nodes.
Anyway, the cluster should get back to the proper size after 10 min.

### Deployment

- Kubeadm: avoid panicing if the user has malformed the kubeconfig in the cluster-info config map to not include a valid current context. Include proper validation at the appropriate locations and throw errors instead.

## Changelog since v1.23.0-beta.0

## Changes by Kind

### API Change

- Add gRPC probe to Pod.Spec.Container.{Liveness,Readiness,Startup}Probe (#106463, @SergeyKanzhelev) [SIG API Machinery, Apps, CLI, Node and Testing]

- Revert kubelet prober metrics `pod` tag to include actual pod name ([#118549](https://github.com/kubernetes/kubernetes/pull/118549), [@a7i](https://github.com/a7i)) [SIG Node]

### (No, really, you MUST read this before you upgrade)

- Kubeadm: make sure the etcd static pod startup probe uses /health?serializable=false while the liveness probe uses /health?serializable=true&exclude=NOSPACE. The NOSPACE exclusion would allow administrators to address space issues one member at a time. ([#110744](https://github.com/kubernetes/kubernetes/pull/110744), [@neolit1...
