### Upload Progress ([.kt][UploadProgressKotlin], [.java][UploadProgressJava])

Upload a file to a server (for example, Imgur) and report progress as the request body is being written. You can implement a ProgressListener to receive updates and wrap the original request body with ProgressRequestBody. This allows you to monitor how many bytes have been uploaded and calculate the percentage of completion.

   * Instead, copy the list using {@link ImmutableList#copyOf(Collection)} (for example), then
   * serialize the copy. Other methods similar to this do not implement serialization at all for
   * this reason.
   *
   * <p><b>Java 8+ users:</b> many use cases for this method are better addressed by {@link

 selector, fn) {\n  return function handler(event) {\n    const domElements = element.querySelectorAll(selector)\n\n    for (let { target } = event; target && target !== this; target = target.parentNode) {\n      for (const domElement of domElements) {\n        if (domElement !== target) {\n          continue\n        }\n\n        hydrateObj(event, { delegateTarget: target })\n\n        if (handler.oneOff) {\n          EventHandler.off(element, event.type, selector, fn)\n        }\n\n        return...

  Example: suppose you develop a custom plugin that denies Pods that have a `schedulable=false` label.

- Enhance Azure cloud provider code to support both AAD and ADFS authentication. ([#80841](https://github.com/kubernetes/kubernetes/pull/80841), [@rjaini](https://github.com/rjaini))
- kubeadm: implement support for concurrent add/remove of stacked etcd members ([#79677](https://github.com/kubernetes/kubernetes/pull/79677), [@neolit123](https://github.com/neolit123))

## Changelog since v1.15.0

* kubeadm: implement support for concurrent add/remove of stacked etcd members ([#79677](https://github.com/kubernetes/kubernetes/pull/79677), [@neolit123](https://github.com/neolit123))

  * New SchedulerExtender enables users to implement custom
out-of-(the-scheduler)-process scheduling predicates and priority functions,
for example to schedule pods based on resources that are not directly managed

- Added support in the Kubelet for monitoring the health of devices allocated via Dynamic Resource Allocation (DRA) and report it in the `pod.status.containerStatuses.allocatedResourcesStatus` field. This required the DRA plugin to implement the new v1alpha1 `NodeHealth` gRPC service. This feature was controlled by the `ResourceHealthStatus` feature gate.
