* The Kubelet now explicitly registers all of its command-line flags with an internal flagset, which prevents flags from third party libraries from unintentionally leaking into the Kubelet's command-line API. Many unintentionally leaked flags are now marked deprecated, so that users have a chance to migrate away from them before they are removed. In addition, one previously leaked flag, --cloud-provider-gce-lb-src-cidrs, has been entirely removed from the Kubelet's command-line...

*   The kube-scheduler command now supports a `--config` flag, which is the location of a file containing a serialized scheduler configuration. Most other kube-scheduler flags are now deprecated.
