* 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).

  // Exit status of 0 is treated as live/healthy and non-zero is unhealthy.

* Default values differ between the Kubelet's componentconfig (config file) API and the Kubelet's command line. Be sure to review the default values when migrating to using a config file. For example, the authz mode is set to "AlwaysAllow" if you rely on the command line, but defaults to the more secure "Webhook" mode if you load config from a file.

- client-go
  - The deprecated versionless API group accessors (like `clientset.Apps()`) have been removed. Use an explicit version instead (like `clientset.AppsV1()`) ([#74422](https://github.com/kubernetes/kubernetes/pull/74422), [@liggitt](https://github.com/liggitt))

    * clusters. When that var is set to true, the command line flag enabling kubelet
    * client certificate rotation will be added to the kubelet command line.
* Make sure that resources being updated are handled correctly by Quota system ([#52452](https://github.com/kubernetes/kubernetes/pull/52452), [@gnufied](https://github.com/gnufied))

- Metrics Server image bumped to v0.5.2 ([#106492](https://github.com/kubernetes/kubernetes/pull/106492), [@serathius](https://github.com/serathius))
- Modified command line errors (for example, `kubectl list` -> `unknown command`) that were printed as log message with escaped line breaks instead of a multi-line plain text, making the error hard to read.

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