 ## kubectl integration
 
-Since [v1.14][kubectl announcement] the kustomize build system has been included in kubectl.
+The kustomize build flow at [v2.0.3] was added
+to [kubectl v1.14][kubectl announcement].  The kustomize
+flow in kubectl has remained frozen at v2.0.3 while work
+to extract kubectl from the k/k repo, and work to remove
+kustomize's dependence on core k/k code ([#2506]) has proceeded.
+The reintegration effort is tracked in [#1500] (and its blocking
+issues).
