 **Security and Setup** : Users concerned with security will find that [RBAC](https://kubernetes.io//docs/admin/authorization/rbac), now _beta_ adds a significant security benefit through more tightly scoped default roles for system components. The default RBAC policies in 1.6 grant scoped permissions to control-plane components, nodes, and controllers. RBAC allows cluster administrators to selectively grant particular users or service accounts fine-grained access to specific resources on a per-namespace basis. RBAC users upgrading from 1.5 to 1.6 should view the guidance [here](https://kubernetes.io//docs/admin/authorization/rbac.md#upgrading-from-15).

 **Advanced Scheduling** : This release adds a set of [powerful and versatile scheduling constructs](https://kubernetes.io/docs/user-guide/node-selection/) to give you greater control over how pods are scheduled, including rules to restrict pods to particular nodes in heterogeneous clusters, and rules to spread or pack pods across failure domains such as nodes, racks, and zones.
