 Key:
 
 * `✓` Exactly the same features / API objects in both client-go and the Kubernetes
   version.
 * `+` client-go has features or api objects that may not be present in the
-  Kubernetes cluster. alpha/beta api present in the kubernetes cluster may not
-  be supported by client-go. Everything they have in common will work.
+  Kubernetes cluster, but everything they have in common will work. Please
+  note that alpha APIs may vanish or change significantly in a single release.
+* `†` client-go has new features or api objects, and some APIs running in the
+  cluster may have been deprecated and removed from client-go. But everything
+  they share in common (i.e., most APIs) will work.
 * `-` The Kubernetes cluster has features the client-go library can't use
   (additional API objects, etc).
