*   In `Layer.call`, `AutoCastVariable`s will no longer be casted within
        `MirroredStrategy.run` or `ReplicaContext.merge_call`. This is because a
        thread local variable is used to determine whether `AutoCastVariable`s
        are casted, and those two functions run with a different thread. Note
        this only applies if one of these two functions is called within
        `Layer.call`; if one of those two functions calls `Layer.call`,

### Avoiding permanent beta

From Kubernetes 1.20 onwards, SIG Architecture will implement a new policy to transition all REST APIs out of beta within nine months. The idea behind the new policy is to avoid features staying in beta for a long time. Once a new API enters beta, it will have nine months to either:

 - reach GA, and deprecate the beta, or
