- For kube-up and derived configurations, CoreDNS will honor master taints, for consistency with kube-dns behavior. ([#70868](https://github.com/kubernetes/kubernetes/pull/70868), [@justinsb](https://github.com/justinsb))

## Changelog since v1.15.6

### Other notable changes

* Change GCP ILB firewall names to contain the "k8s-fw-" prefix like the rest of the firewall rules. This is needed for consistency and also for other components to identify the firewall rule as k8s/service-controller managed.

- Previously, `kubectl scale` returned the error message `error: no objects passed to scale <GroupResource> "<ResourceName>" not found` when the specified resource did not exist. 

resource version option, when passed to a list call, is now consistently interpreted as the minimum allowed resource version.  Previously when listing resources that had the watch cache disabled clients could retrieve a snapshot at that exact resource version.  If the client requests a resource version newer than the current state, a TimeoutError is returned suggesting the client retry in a few seconds.  This behavior is now consistent for both single item retrieval and list calls, and for when the...
