* The IP address and port for kube-proxy metrics server is now configurable via flag `--metrics-bind-address` ([#48625](https://github.com/kubernetes/kubernetes/pull/48625), [@mrhohn](https://github.com/mrhohn))
  * Special notice for kube-proxy in 1.7+ (including 1.7.0):
    * Healthz server (/healthz) will be served on 0.0.0.0:10256 by default.
    * Metrics server (/metrics and /proxyMode) will be served on 127.0.0.1:10249 by default.

* The implicit registration of Prometheus metrics for request count and latency have been removed, and a plug-able interface was added. If you were using our client libraries in your own binaries and want these metrics, add the following to your imports in the main package: "k8s.io/pkg/client/metrics/prometheus".
