#### Bug fixes

    * Added --config-map and --config-map-namespace command line options.
    * If --config-map is set, kube-dns will load dynamic configuration from the config map
      referenced by --config-map-namespace, --config-map. The config-map supports
      the following properties: "federations".
    * --federations flag is now deprecated. Prefer to set federations via the config-map.
