- Kube-apiserver: Each unique set of etcd server overrides specified with `--etcd-servers-overrides` surfaced health checks named `etcd-override-<index>` and `etcd-override-readiness-<index>`. These checks were still excluded by the `?exclude=etcd` and `?exclude=etcd-readiness` directives.

  - 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.

- Features:

- Azure cloud provider now supports unmanaged nodes (such as on-prem) that are labeled with `kubernetes.azure.com/managed=false` and `alpha.service-controller.kubernetes.io/exclude-balancer=true` ([#67984](https://github.com/kubernetes/kubernetes/pull/67984), [@feiskyer](https://github.com/feiskyer)) Courtesy of SIG Azure, and SIG Cloud Provider

- Revised the logic for `DaemonSet` rolling update to exclude nodes if scheduling constraints are not met. This eliminates the problem of rolling updates to a `DaemonSet` getting stuck around tolerations.

* You can now use `--ipvs-exclude-cidrs` to specify a list of CIDR's which the IPVS proxier should not touch when cleaning up IPVS rules. ([#62083](https://github.com/kubernetes/kubernetes/pull/62083), [@rramkumar1](https://github.com/rramkumar1))

* Fix problems with scaling up the cluster when unschedulable pods have some persistent volume claims. ([#44860](https://github.com/kubernetes/kubernetes/pull/44860), [@mwielgus](https://github.com/mwielgus))
* Exclude nodes labeled as master from LoadBalancer / NodePort; restores documented behaviour. ([#44745](https://github.com/kubernetes/kubernetes/pull/44745), [@justinsb](https://github.com/justinsb))

  * Fix corner-case with OnlyLocal Service healthchecks. ([#44313](https://github.com/kubernetes/kubernetes/pull/44313), [@thockin](https://github.com/thockin))
