 - reach GA, and deprecate the beta, or
 - have a new beta version _(and deprecate the previous beta)_.

If a REST API reaches the end of that nine-month countdown, then the next Kubernetes release will deprecate that API version. More information can be found on [the Kubernetes Blog](https://kubernetes.io/blog/2020/08/21/moving-forward-from-beta/).
