 - 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. ([#99130](https://github.com/kubernetes/kubernetes/pull/99130), [@ayberk](https://github.com/ayberk))...

- Kube-proxy:...

* Deprecate the beta labels for zones ("failure-domain.beta.kubernetes.io/zone") and  ([#81431](https://github.com/kubernetes/kubernetes/pull/81431), [@andrewsykim](https://github.com/andrewsykim))
    * regions ("failure-domain.beta.kubernetes.io/region") in favor of their GA equivalents:
    * "topology.kubernetes.io/zone" and "topology.kubernetes.io/region".

### kube-dns
* Adds support for configurable DNS stub domains and upstream nameservers.
  The following configuration options have been added to the `kube-system:kube-dns` ConfigMap:
  ```
  "stubDomains": {
    "acme.local": ["1.2.3.4"]
  },
  ```
  is a map of domain to list of nameservers for the domain. This is used
  to inject private DNS domains into the kube-dns namespace. In the above

        * `beta.kubernetes.io/instance-type`
        * `beta.kubernetes.io/os`
        * `beta.kubernetes.io/arch`
        * `failure-domain.kubernetes.io/zone`
        * `failure-domain.kubernetes.io/region`
        * `failure-domain.beta.kubernetes.io/zone`
        * `failure-domain.beta.kubernetes.io/region`
        * `[*.]kubelet.kubernetes.io/*`
        * `[*.]node.kubernetes.io/*`

fetching of public verifying keys, by enabling the Alpha `ExternalServiceAccountTokenSigner` feature gate and specifying `--service-account-signing-endpoint`. The flag value can either be the location of a Unix domain socket on a filesystem, or be prefixed with an @ symbol and name a Unix domain socket in the abstract socket namespace.

	* Mechanism of adding `federation domain maps` to kube-dns deployment via `--federations` flag is superseded by adding/updating `federations` key in `kube-system/kube-dns` configmap. If user is using kubefed tool to join cluster federation, adding federation domain maps to kube-dns is already taken care by `kubefed join` and does not need further action.

### Scheduling

  - Opaque Integer Resources (OIRs) are deprecated and will be removed in
    version 1.9. Extended Resources (ERs) are a drop-in replacement for OIRs. You can use
    any domain name prefix outside of the `kubernetes.io/` domain instead of the
    `pod.alpha.kubernetes.io/opaque-int-resource-` prefix.
