- [KCCM - service controller]: enable connection draining for terminating pods upon node downscale by the cluster autoscaler. This is done by not reacting to the taint used by the cluster autoscaler to indicate that the node is going away soon, thus keeping the node referenced by the load balancer until the VM has been completely...

the Cluster Autoscaler, which provides improved performance and error reporting.

### SIG Cluster Lifecycle

[SIG Cluster Lifecycle][] is responsible for the user experience of deploying,
upgrading, and deleting clusters.

For the 1.8 release, SIG Cluster Lifecycle continued to focus on expanding the

- E2e framework: the `node-role.kubernetes.io/master` taint has been removed from the default value of `--non-blocking-taints` flag. You may need to set `--non-blocking-taints` explicitly if the cluster to be tested has nodes with the deprecated `node-role.kubernetes.io/master` taint. ([#118510](https://github.com/kubernetes/kubernetes/pull/118510), [@SataQiu](https://github.com/SataQiu)) [SIG Testing]

- Kubeadm: add support for the "ci/k8s-master" version label as a replacement for "ci-cross/*", which no longer exists. ([#86609](https://github.com/kubernetes/kubernetes/pull/86609), [@Pensu](https://github.com/Pensu)) [SIG Cluster Lifecycle]

### SIG Network

For 1.13, the areas of focus were in IPv6, DNS improvements and some smaller items:
CoreDNS is now the default cluster DNS passing all of the scale/resource usage tests

- Kubeadm: http://git.k8s.io/enhancements/keps/sig-cluster-lifecycle/kubeadm/2067-rename-master-label-taint/README.md ([#95382](https://github.com/kubernetes/kubernetes/pull/95382), [@neolit123](https://github.com/neolit123)) [SIG Cluster Lifecycle]
  - The label applied to control-plane nodes "node-role.kubernetes.io/master" is now deprecated and will be removed in a future release after a GA deprecation period.

### Detection

Kubernetes Audit logs may indicate if the user name was misspelled to bypass the restriction placed on which user is a pod allowed to run as.
