- kube-scheduler dropped support for configuration files with apiVersion `componentconfig/v1alpha1`. Ensure kube-scheduler is configured using command-line flags or a configuration file with apiVersion `kubescheduler.config.k8s.io/v1alpha1` before upgrading to 1.13.

- The /configz endpoint of kubelet, scheduler, cloud controller manager, and kube-proxy serializes the APIVersion and Kind fields as well as using public types instead of internal.

  - `response.patch` and `response.patchType` are not permitted from validating admission webhooks
  - `apiVersion: "admission.k8s.io/v1"` is required
  - `kind: "AdmissionReview"` is required

      Federations can be configured by settings the "federations" field to the value currently
      set in the command line.
    * Example:
      ```yaml
      kind: ConfigMap
      apiVersion: v1
      metadata:
        name: kube-dns
        namespace: kube-system
      data:
        federations: abc=def
      ```
