    To address this, the new debian-hyperkube-base image (v1.1.0) uses the
    debian-iptables base image (v12.1.0), which includes iptables-wrapper, a
    script used to determine the correct iptables mode to run in. ([#92494](https://github.com/kubernetes/kubernetes/pull/92494), [@justaugustus](https://github.com/justaugustus)) [SIG Cluster Lifecycle and Release]

## Dependencies

* API discovery failures no longer crash the kube controller manager via the garbage collector. ([#55259](https://github.com/kubernetes/kubernetes/pull/55259), [@ironcladlou](https://github.com/ironcladlou))
* Fix bug where master startup script on GCP failed randomly due to concurrent iptables invocations. ([#55945](https://github.com/kubernetes/kubernetes/pull/55945), [@x13n](https://github.com/x13n))



# v1.8.4

- Projects which use k8s.io/code-generator and invoke `generate-groups` or `generate-internal-groups.sh` have a new, simpler script (`kube_codegen.sh`) they can use.  The old scripts are deprecated but remain intact. ([#117262](https://github.com/kubernetes/kubernetes/pull/117262), [@thockin](https://github.com/thockin)) [SIG API Machinery and Instrumentation]

can now be deployed using the `federation/deploy/deploy.sh` script. This script does not depend on any of the development environment shell library/scripts. This is an alternative to the current `federation-up.sh`/`federation-down.sh` scripts. Both the scripts are going to co-exist in this release, but the `federation-up.sh`/`federation-down.sh` scripts might be removed in a future release in favor of `federation/deploy/deploy.sh` script.

  * In very large clusters it may happen that a few nodes won’t register in API
server in a given timeframe for whatever reasons (networking issue, machine
failure, etc.). Normally when kube-up script will encounter even one NotReady
node it will fail, even though the cluster most likely will be working. We
added an environmental variable to kube-up ALLOWED\_NOTREADY\_NODES that
