- Kube-apiserver: the componentstatus API is deprecated. This API provided status of etcd, kube-scheduler, and kube-controller-manager components, but only worked when those components were local to the API server, and when kube-scheduler and kube-controller-manager exposed unsecured health endpoints. Instead of this API, etcd health is included in the kube-apiserver health check and kube-scheduler/kube-controller-manager health checks can be made directly against those components' health endpoints....

- Performance of the inter-pod affinity/anti-affinity feature is improved over 100X via algorithmic optimization.
- DaemonSet pods, which used to be scheduled by the DaemonSet controller, will be scheduled by the default scheduler in 1.12. This change allows DaemonSet pods to enjoy all the scheduling features of the default scheduler.

* Default scheduler code is moved out of the plugin directory. ([#57852](https://github.com/kubernetes/kubernetes/pull/57852), [@misterikkit](https://github.com/misterikkit))
    * plugin/pkg/scheduler -> pkg/scheduler
    * plugin/cmd/kube-scheduler -> cmd/kube-scheduler
