*   Kubelet now uses an explicit cm.GetDevicePluginResourceCapacity() function that makes it possible to more accurately determine what resources are inactive and return a more accurate view of available resources.
    *   Extends the device plugin checkpoint data to record registered resources so that we can finish resource removing devices even upon kubelet restarts.

### Storage

* You can now use `kubectl api-resources` to discover resources.
 ([#42873](https://github.com/kubernetes/kubernetes/pull/42873),  [@xilabao](https://github.com/xilabao))
* You can now display requests/limits of extended resources in node allocated resources. ([#46079](https://github.com/kubernetes/kubernetes/pull/46079), [@xiangpengzhao](https://github.com/xiangpengzhao))

* Fixes a flaw (CVE-2019-11253) in json/yaml decoding where large or malformed documents could consume excessive server resources. Request bodies for normal API requests (create/delete/update/patch operations of regular resources) are now limited to 3MB.
