### Kubernetes Provider RBACs
Starting with v3.1, the Kubernetes Providers now use the [EndpointSlices API](https://kubernetes.io/docs/concepts/services-networking/endpoint-slices/) (Kubernetes >=v1.21) to discover service endpoint addresses.
It also brings NodePort load-balancing which requires Nodes resources lookup.
Therefore, in the corresponding RBACs (see [KubernetesIngress](../routing/providers/kubernetes-ingress.md#configuration-example), [KubernetesCRD](../reference/dynamic-configuration/kubernetes-crd.md#rbac), and [KubernetesGateway](../reference/dynamic-configuration/kubernetes-gateway.md#rbac) provider RBACs),
the `endpoints` right has to be removed and the following `endpointslices` right has to be added.

In v3.1, the KubernetesGateway Provider is no longer an experimental feature.

The `kubernetesgateway` option should be removed from the experimental section of the static configuration.
To configure `kubernetesgateway`, please check out the [KubernetesGateway Provider documentation](../providers/kubernetes-gateway.md).

### IngressClass Lookup
The Kubernetes Ingress provider option `disableIngressClassLookup` has been deprecated in v3.1.1, and will be removed in the next major version.
Please use the `disableClusterScopeResources` option instead to avoid cluster scope resources discovery (IngressClass, Nodes).
