    for more details.
+- `CustomResourceDefaulting`: Enable CRD support for default values in OpenAPI v3 validation schemas.
 - `CustomResourcePublishOpenAPI`: Enables publishing of CRD OpenAPI specs.
 - `CustomResourceSubresources`: Enable `/status` and `/scale` subresources

   to discover plugins such as [CSI volume drivers](/docs/concepts/storage/volumes/#csi).
 - `KubeletPodResources`: Enable the kubelet's pod resources grpc endpoint.
    See [Support Device Monitoring](https://git.k8s.io/community/keps/sig-node/compute-device-assignment.md) for more details.
+- `LegacyNodeRoleBehavior`: When disabled, legacy behavior in service load balancers and node disruption will ignore the `node-role.kubernetes.io/master` label in favor of the feature-specific labels.
 - `LocalStorageCapacityIsolation`: Enable the consumption of [local ephemeral storage](/docs/concepts/configuration/manage-compute-resources-container/) and also the `sizeLimit` property of an [emptyDir volume](/docs/concepts/storage/volumes/#emptydir).
 - `LocalStorageCapacityIsolationFSQuotaMonitoring`: When `LocalStorageCapacityIsolation` is enabled for [local ephemeral storage](/docs/concepts/configuration/manage-compute-resources-container/) and the backing filesystem for [emptyDir volumes](/docs/concepts/storage/volumes/#emptydir) supports project quotas and they are enabled, use project quotas to monitor [emptyDir volume](/docs/concepts/storage/volumes/#emptydir) storage consumption rather than filesystem walk for better performance and accuracy.
 - `MountContainers`: Enable using utility containers on host as the volume mounter.
 - `MountPropagation`: Enable sharing volume mounted by one container to other containers or pods.
   For more details, please see [mount propagation](/docs/concepts/storage/volumes/#mount-propagation).
+- `NodeDisruptionExclusion`: Enable use of the node label `node.kubernetes.io/exclude-disruption` which prevents nodes from being evacuated during zone failures.
 - `NodeLease`: Enable the new Lease API to report node heartbeats, which could be used as a node health signal.
 - `NonPreemptingPriority`: Enable NonPreempting option for PriorityClass and Pod. 
 - `PersistentLocalVolumes`: Enable the usage of `local` volume type in Pods.

 - `ServiceNodeExclusion`: Enable the exclusion of nodes from load balancers created by a cloud provider.

 - `StorageVersionHash`: Allow apiservers to expose the storage version hash in the discovery.
