- Kubeadm: deprecated the kubeadm `RootlessControlPlane` feature gate (previously alpha), given that the core K8s `UserNamespacesSupport` feature gate graduated to beta in 1.30.

  // containers as root without actually having root privileges on the host.
  // This field is alpha-level and is only honored by servers that enable the UserNamespacesSupport feature.
  // +k8s:conversion-gen=false
  // +optional
  optional bool hostUsers = 37;

  // SchedulingGates is an opaque list of values that if specified will block scheduling the pod.

- Enabled use of pods with volumes and user namespaces. The feature gate was renamed from `UserNamespacesStatelessPodsSupport` to `UserNamespacesSupport`. ([#118691](https://github.com/kubernetes/kubernetes/pull/118691), [@giuseppe](https://github.com/giuseppe))
