* Update amd64 kube-proxy base image to debian-iptables-amd64:v5 ([#39725](https://github.com/kubernetes/kubernetes/pull/39725), [@ixdy](https://github.com/ixdy))
* Update kube-proxy image to be based off of Debian 8.6 base image. ([#39695](https://github.com/kubernetes/kubernetes/pull/39695), [@ixdy](https://github.com/ixdy))

* kubectl rolling-update support for same image ([#24645](https://github.com/kubernetes/kubernetes/pull/24645), [@jlowdermilk](https://github.com/jlowdermilk))
* Add an entry to the salt config to allow Debian jessie on GCE. ([#25123](https://github.com/kubernetes/kubernetes/pull/25123), [@jlewi](https://github.com/jlewi))
    * As with the existing Wheezy image on GCE, docker is expected to already be installed in the image.

- Simple script based hyperkube image that bundles all the necessary binaries. This is an equivalent replacement for the image based on the go based hyperkube command + image. ([#84662](https://github.com/kubernetes/kubernetes/pull/84662), [@dims](https://github.com/dims))

### SIG Release

- Use debian-base instead of busybox as base image for server images ([#70245](https://github.com/kubernetes/kubernetes/pull/70245), [@ixdy](https://github.com/ixdy))
