### Provider-specific Notes

#### Various

   Core changes:

  * Support for load balancers with source ranges

#### AWS

Core changes:

  * Support for ELBs with complex configurations: better subnet selection with
multiple subnets, and internal ELBs
  * Support for VPCs with private dns names
  * Multiple fixes to EBS volume mounting code for robustness, and to support

    *   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`,

and PVC objects can be deleted properly.

* Use of subPath module with hostPath volumes can cause issues during reconstruction ([#61446](https://github.com/kubernetes/kubernetes/issues/61446)) and with containerized kubelets ([#61456](https://github.com/kubernetes/kubernetes/issues/61456)). The workaround for this issue is to specify the complete path in the hostPath volume. Use of subPathmounts nested within atomic writer volumes (configmap, secret, downwardAPI, projected) does not work...
