 #### Gateway API gateways
 
-The Gateway API version `gateway.networking.k8s.io/v1` and `gateway.networking.k8s.io/v1alpha2` are supported.
+The Gateway API versions `gateway.networking.k8s.io/v1` and `gateway.networking.k8s.io/v1beta1` are supported.
 
 To enable automatic management of `DNSEntries`, annotate the Gateway API `Gateway` resource with `dns.gardener.cloud/dnsnames="*"`.
 The domain names are extracted from the `spec.listeners.hostnames` field and from the field `spec.hostnames` of related `HTTPRoute` resources.
