* Dual stack services (Phase II of IPv6DualStack feature) are enabled via the IPVS proxier. iptables proxier does not support dualstack yet. Dualstack iptables proxier is WIP and should catchup soon. ([#82091](https://github.com/kubernetes/kubernetes/pull/82091), [@khenidak](https://github.com/khenidak))
    * to enable, kube-proxy must be have the following flags:

  The API Server will no longer proxy non-101 responses for upgrade requests. This could break proxied backends (such as an extension API server) that respond to upgrade requests with a non-101 response code.
