- Ginkgo: when e2e tests are invoked through ginkgo-e2e.sh, the default now is to use color escape sequences only when connected to a terminal. `GINKGO_NO_COLOR=y/n` can be used to override that default. ([#111633](https://github.com/kubernetes/kubernetes/pull/111633), [@pohly](https://github.com/pohly))

  After the connection closed(received GOAWAY), the client's other in-flight requests won't be affected, and the client will reconnect. 
  The flag min value is 0 (off), max is .02 (1/50 requests); .001 (1/1000) is a recommended starting point.

## Known Issues

- There is a known issue [coredns/coredns#2629](https://github.com/coredns/coredns/issues/2629) in CoreDNS 1.3.1, wherein if the Kubernetes API shuts down while CoreDNS is connected, CoreDNS will crash. The issue is fixed in CoreDNS 1.4.0 in [coredns/coredns#2529](https://github.com/coredns/coredns/pull/2529).

* Fix kubelet to correctly umounts mount points for glusterfs when transport endpoint is not connected and nfs when there is a stale file handle ([#58660](https://github.com/kubernetes/kubernetes/pull/58660), [@humblec](https://github.com/humblec))

- kubeadm now works better when not connected to the Internet. In addition,  common kubeadm commands will now work without an available networking interface. ([#67397](https://github.com/kubernetes/kubernetes/pull/67397), [@neolit123](https://github.com/neolit123))
