### Network

* Fixed kube-proxy to work correctly with iptables 1.6.2 and later. ([#60978](https://github.com/kubernetes/kubernetes/pull/60978), [@danwinship](https://github.com/danwinship))

* Makes the kube-dns addon optional so that users can deploy their own DNS solution. ([#57113](https://github.com/kubernetes/kubernetes/pull/57113), [@wwwtyro](https://github.com/wwwtyro))

* Mark the LBaaS v1 of OpenStack cloud provider deprecated. ([#52821](https://github.com/kubernetes/kubernetes/pull/52821), [@FengyunPan](https://github.com/FengyunPan))
* Mark image as deliberately optional in v1 Container struct.  Many objects in the Kubernetes API inherit the container struct and only Pods require the field to be set. ([#48406](https://github.com/kubernetes/kubernetes/pull/48406), [@gyliu513](https://github.com/gyliu513))

* OpenStack cloud provider supports Cinder v3 API. ([#52910](https://github.com/kubernetes/kubernetes/pull/52910), [@FengyunPan](https://github.com/FengyunPan))
* kube-up: Add optional addon CoreDNS.  ([#55728](https://github.com/kubernetes/kubernetes/pull/55728), [@rajansandeep](https://github.com/rajansandeep))
    * Install CoreDNS instead of kube-dns by setting CLUSTER_DNS_CORE_DNS value to 'true'.
