- Topology Hints now excludes control plane notes from capacity calculations. ([#104744](https://github.com/kubernetes/kubernetes/pull/104744), [@robscott](https://github.com/robscott))

  - the node label `alpha.service-controller.kubernetes.io/exclude-balancer` which excludes a node from cloud load balancers (using Service Type=LoadBalancer) is deprecated in favor of `node.kubernetes.io/exclude-balancer`. Support for `alpha.service-controller.kubernetes.io/exclude-balancer` will be removed in v1.18.

- Messages of `DisruptionTarget` condition now excludes preemptor pod metadata ([#114914](https://github.com/kubernetes/kubernetes/pull/114914), [@mimowo](https://github.com/mimowo))

* Add a new feature gate for enabling an alpha annotation which, if present, excludes the annotated node from being added to a service load balancers. ([#54644](https://github.com/kubernetes/kubernetes/pull/54644), [@brendandburns](https://github.com/brendandburns))

  - The calculations for Pod topology spread skew now excludes nodes that
  don't match the node affinity/selector. This may lead to unschedulable pods if you previously had pods
  matching the spreading selector on those excluded nodes (not matching the node affinity/selector),

* Kubeadm now includes CoreDNS version 1.6.5 ([#85109](https://github.com/kubernetes/kubernetes/pull/85109), [@rajansandeep](https://github.com/rajansandeep))
    *  - `kubernetes` plugin adds metrics to measure kubernetes control plane latency.
    *  -  the `health` plugin now includes the `lameduck` option by default, which waits for a duration before shutting down.

- Kubernetes 1.12 includes a large number of metadata agent improvements, including expanding the metadata agent's access to all API groups and removing metadata agent config maps in favor of command line flags.
