 *  New: Connection coalescing. OkHttp may reuse HTTP/2 connections across calls that share an IP
    address and HTTPS certificate, even if their domain names are different.
 *  New: MockWebServer's `RecordedRequest` exposes the requested `HttpUrl` with `getRequestUrl()`.


## Version 3.6.0

- For volumes that allow attaches across multiple nodes, attach and detach operations across different nodes are now executed in parallel. ([#89239](https://github.com/kubernetes/kubernetes/pull/89239), [@verult](https://github.com/verult)) [SIG Apps, Node and Storage]

  - support for the `v1alpha3` configuration file format is deprecated and will be removed in 1.14. Use `kubeadm config migrate` to migrate `v1alpha3` configuration files to `v1beta1`, which provides improvements in image repository management, addons configuration, and other areas. The documentation for `v1beta1` can be found here: https://godoc.org/k8s.io/kubernetes/cmd/kubeadm/app/apis/kubeadm/v1beta1
