- The deprecated cloud providers `ovirt`, `cloudstack` and `photon` have been removed ([#72178](https://github.com/kubernetes/kubernetes/pull/72178), [@dims](https://github.com/dims))
  - The `Cinder` and `ScaleIO` volume providers have been deprecated and will be removed in a future release. ([#80099](https://github.com/kubernetes/kubernetes/pull/80099), [@dims](https://github.com/dims))

* Remove deprecated ScheduledJobs endpoints, use CronJobs instead. ([#49930](https://github.com/kubernetes/kubernetes/pull/49930), [@soltysh](https://github.com/soltysh))
* [Federation] Make the hpa scale time window configurable ([#49583](https://github.com/kubernetes/kubernetes/pull/49583), [@irfanurrehman](https://github.com/irfanurrehman))

### Internal Storage Layer
* **[stable]** The internal storage layer for kubernetes cluster state has been updated to use etcd v3 by default. Existing clusters will have to plan for a data migration window. ([docs](https://kubernetes.io/docs/tasks/administer-cluster/upgrade-1-6/))([kubernetes/features#44](https://github.com/kubernetes/enhancements/issues/44))

### kubeadm

    *   New `tf.data.Dataset.reduce()` API allows users to reduce a finite
        dataset to a single element using a user-provided reduce function.
    *   New `tf.data.Dataset.window()` API allows users to create finite windows
        of input dataset; when combined with the `tf.data.Dataset.reduce()` API,
        this allows users to implement customized batching.
