* Scale subresource now has a new <code>targetSelector</code> field in its status. This field supports the new set-based selectors supported
by Deployments, but in a serialized format.
     * Spec change:
        * Deployment’s [selector](http://kubernetes.io/docs/user-guide/labels/#label-selectors) is now more general (supports set-based selector; it only supported
equality-based selector in 1.1).

*   Refactor kube-scheduler configuration ([#52428](https://github.com/kubernetes/kubernetes/pull/52428))
    *   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. ([#52562](https://github.com/kubernetes/kubernetes/pull/52562),[ @ironcladlou](https://github.com/ironcladlou))
