 ## v2.10
 
-### Nomad Namespace
+### Kubernetes CRDs
 
-In `v2.10`, the `namespace` option of the Nomad provider is deprecated, please use the `namespaces` options instead.
+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.
+
+As the Kubernetes CRD provider still works with both API Versions (`traefik.io/v1alpha1` and `traefik.containo.us/v1alpha1`),
+it means that for the same kind, namespace and name, the provider will only keep the `traefik.io/v1alpha1` resource.
+
+In addition, the Kubernetes CRDs API Version `traefik.io/v1alpha1` will not be supported in Traefik v3 itself.
+
+### Traefik Hub
+
+In `v2.10`, Traefik Hub is GA and the `experimental.hub` flag is deprecated.
