## Impact

### Kubernetes CRDs API Group `traefik.containo.us`

In v2.10, the Kubernetes CRDs API Group `traefik.containo.us` is deprecated, and its support will end starting with Traefik v3. Please use the API Group `traefik.io` instead.

### Kubernetes CRDs API Version `traefik.io/v1alpha1`

The newly introduced Kubernetes CRD API Version `traefik.io/v1alpha1` will subsequently be removed in Traefik v3. The following version will be `traefik.io/v1`.
