### Cluster Autoscaler
* If you are using (or planning to use) Cluster Autoscaler please wait for Kubernetes 1.6.1. In 1.6.0 Cluster Autoscaler
may occasionally increase the size of the cluster a bit more than it is actually needed, when there are
unschedulable pods, scale up is required and cloud provider is slow to set up networking for new nodes.

* Fixed an issue looking up cronjobs when they existed in more than one API version ([#52227](https://github.com/kubernetes/kubernetes/pull/52227), [@liggitt](https://github.com/liggitt))

* Windows runtime endpoints is now switched to 'npipe:////./pipe/dockershim' from 'tcp://localhost:3735'. ([#69516](https://github.com/kubernetes/kubernetes/pull/69516), [@feiskyer](https://github.com/feiskyer))

	Array types are comparable if their array element types are comparable.
	Two array values are equal if their corresponding element values are equal.
	The elements are compared in ascending index order, and comparison stops
	as soon as two element values differ (or all elements have been compared).

	Type parameters are comparable if they are strictly comparable (see below).

feature is now beta. As consequence, all volume mounts in containers are now "rslave" on Linux by default. To make this default work in all Linux environments you should have entire mount tree marked as shareable via "mount --make-rshared /". All Linux distributions that use systemd already have root directory mounted as rshared and hence they need not do anything. In Linux environments without systemd we  recommend running "mount --make-rshared /" during boot, before docker is started. ([#59252](htt...

### Storage

[SIG Storage](https://github.com/kubernetes/community/tree/master/sig-storage) is responsible for storage and volume plugin components.

    * kubeadm - Ensure that the etcd certificates are generated using a proper CN
    * kubeadm - Update generated etcd peer certificate to include localhost addresses for the default configuration.
    * kubeadm - Increase the manifest update timeout to make upgrades a bit more reliable.

- Make Azure clients only retry on specified HTTP status codes ([#88017](https://github.com/kubernetes/kubernetes/pull/88017), [@feiskyer](https://github.com/feiskyer)) [SIG Cloud Provider]

`kubeadm` applies a number of deprecations and removals of deprecated features in this release. More details are available in the Urgent Upgrade Notes and Kind / Deprecation sections.
