* The new metrics are:

	    * cloudprovider_gce_api_request_duration_seconds{request, region, zone}

	    * cloudprovider_gce_api_request_errors{request, region, zone}

	    * request is the specific function that is used.

	    * region is the target region (Will be "<n/a>" if not applicable)

	    * zone is the target zone (Will be "<n/a>" if not applicable)

 - Newly provisioned PVs by EBS plugin will no longer use the deprecated "failure-domain.beta.kubernetes.io/zone" and "failure-domain.beta.kubernetes.io/region" labels. It will use "topology.kubernetes.io/zone" and "topology.kubernetes.io/region" labels instead.

* Trust region if found from AWS metadata ([#38880](https://github.com/kubernetes/kubernetes/pull/38880), [@justinsb](https://github.com/justinsb))
* Remove duplicate calls to DescribeInstance during volume operations ([#39842](https://github.com/kubernetes/kubernetes/pull/39842), [@gnufied](https://github.com/gnufied))

    * regions ("failure-domain.beta.kubernetes.io/region") in favor of their GA equivalents:
    * "topology.kubernetes.io/zone" and "topology.kubernetes.io/region".
    * The beta labels "failure-domain.beta.kubernetes.io/zone" and "failure-domain.beta.kubernetes.io/region" will be removed in v1.21

- Reminder: The labels "failure-domain.beta.kubernetes.io/zone" and "failure-domain.beta.kubernetes.io/region" are deprecated in favor of "topology.kubernetes.io/zone" and "topology.kubernetes.io/region" respectively.  All users of the "failure-domain.beta..." labels should switch to the "topology..." equivalents.

- Kubernetes now supports configure TLS termination for AWS NLB([#74910](https://github.com/kubernetes/kubernetes/pull/74910), [@M00nF1sh](https://github.com/M00nF1sh))
- Kubernetes will now consume the AWS region list from the AWS SDK instead of a hard-coded list in the cloud provider. ([#75990](https://github.com/kubernetes/kubernetes/pull/75990), [@mcrute](https://github.com/mcrute))

- PersistentVolume API objects which set NodeAffinities using beta Kubernetes labels for OS, architecture, zone, region, and instance type may now be modified to use the stable Kubernetes labels.
