    * It's now possible to use [Starlette's `StreamingResponse`](https://www.starlette.io/responses/#streamingresponse) with iterators, like [file-like](https://docs.python.org/3/glossary.html#term-file-like-object) objects (as those returned by `open()`).
    * It's now possible to use the low level utility `iterate_in_threadpool` from `starlette.concurrency` (for advanced scenarios).

SIG Storage worked on bringing CSI to feature parity with in-tree functionality, including functionality like resizing, inline volumes, and more. SIG Storage introduces new alpha functionality in CSI that doesn't exist in the Kubernetes Storage subsystem yet, like volume cloning.

Volume cloning enables users to specify another PVC as a "DataSource" when provisioning a new volume. If the underlying storage system supports...

    * If you have to use the legacy in-tree cloud providers, you can rearrange your config like the example below. In case you need the `cloud-config` file (located in `{cloud-config-path}`), you can mount it into the API Server and controller-manager containers using ExtraVolumes like the example below.

    * The body size limit does not apply to subresources like pods/proxy that proxy request content to another server.

* If a pod has a running instance, the stats of its previously terminated instances will not show up in the kubelet summary stats any more for CRI runtimes like containerd and cri-o. ([#77426](https://github.com/kubernetes/kubernetes/pull/77426), [@Random-Liu](https://github.com/Random-Liu))
