* Turned-off etcd listening on public ports as potentially insecure. Removed ([#35192](https://github.com/kubernetes/kubernetes/pull/35192), [@jszczepkowski](https://github.com/jszczepkowski))
    * experimental support for master replication.
* Add support for vSphere Cloud Provider when deploying via kubeup on vSphere. ([#31467](https://github.com/kubernetes/kubernetes/pull/31467), [@kerneltime](https://github.com/kerneltime))

  To request this behaviour, your client software must enable the `WatchListClient` client-go feature gate. Additionally, streaming is only available if supported by the cluster; the API server that you connect to must also support streaming.
