 The question most you’re probably asking now is, “What’s my migration path onto apps/v1 and how soon should I plan on migrating?” All of the group versions prior to apps/v1 are deprecated as of Kubernetes 1.9, and all new code should be developed against apps/v1, but, as discussed above, many of our users treat extensions/v1beta1 as if it were GA.
