- As of v1.25, the PodSecurity `restricted` level no longer requires pods that set .spec.os.name="windows" to also set Linux-specific securityContext fields. If a 1.25+ cluster has unsupported [out-of-skew](https://kubernetes.io/releases/version-skew-policy/#kubelet) nodes prior to v1.23 and wants to ensure namespaces enforcing the `restricted` policy continue to require Linux-specific securityContext fields on all pods, ensure a version of the `restricted` prior to v1.25...

- Support for proxying a request to a peer kube-apiserver if the local apiserver is not able to serve it due to version skew or in the case the requested api is disabled on the local apiserver ([#117740](https://github.com/kubernetes/kubernetes/pull/117740), [@Richabanker](https://github.com/Richabanker)) [SIG API Machinery, Apps, Auth, Cloud Provider, Network, Node and...

For stable features, the `kubectl` tool follows the Kubernetes [version skew policy](https://kubernetes.io/releases/version-skew-policy/);
however, kubectl v1.21 and older do not support the new API for ephemeral containers.

* The dynamic Kubelet config feature will now update the config in the event of a ConfigMap mutation, which reduces the chance for silent config skew. Only name, namespace, and kubeletConfigKey may now be set in `Node.Spec.ConfigSource.ConfigMap`. The least disruptive pattern for config management is still to create a new ConfigMap and incrementally roll out a new `Node.Spec.ConfigSource`. ([#6...

- Kubectl version changed to write a warning message to stderr if the client and server version difference exceeds the supported version skew of +/-1 minor version. ([#98250](https://github.com/kubernetes/kubernetes/pull/98250), [@brianpursley](https://github.com/brianpursley)) [SIG CLI]

- `DynamicKubeletConfig` feature gate has been removed from the API server.
  Dynamic kubelet reconfiguration now can't be used even when older nodes are still
  attempting to rely on it. This is aligned with the Kubernetes version skew policy.
   ([#112643](https://github.com/kubernetes/kubernetes/pull/112643), [@SergeyKanzhelev](https://github.com/SergeyKanzhelev))
- `kubectl wait` command with `jsonpath` flag will wait for target path until timeout.

- The calculations for Pod topology spread skew now exclude nodes that
  don't match the node affinity/selector. This may lead to unschedulable pods if you previously had pods
  matching the spreading selector on those excluded nodes (not matching the node affinity/selector),
