* Kubeadm is currently omitting etcd certificates in a self-hosted deployment; this will be fixed in a point relelase. ([#61322](https://github.com/kubernetes/kubernetes/issues/61322))

## Known Issues

### Summary API in kubelet doesn't have accelerator metrics

   * <p>Iterators returned by the returned iterable do not support the {@link Iterator#remove()}
   * method. The returned lists implement {@link RandomAccess}, whether or not the input list does.
   *
   * <p><b>Note:</b> The current implementation eagerly allocates storage for {@code size} elements.
   * As a consequence, passing values like {@code Integer.MAX_VALUE} can lead to {@link
   * OutOfMemoryError}.
   *

### Scheduling
* **Multiple schedulers**
  * Modify your PodSpecs that currently use the `scheduler.alpha.kubernetes.io/name` annotation on Pod, to instead use the `schedulerName` field in the PodSpec.

     * If the map does not contain the key, the specified value is associated with the key and the value is returned.
     * In either case, the returned value is the value currently associated with the key in the map.
     * </p>
     *
     * @param <K> the key type of {@link HashMap}
     * @param <V> the value type of {@link HashMap}
     * @param map the map

* The global flag "context" now gets applied to `kubectl config view --minify`. In previous versions, this command was only available for `current-context`. Now it will be easier for users to view other non current contexts when minifying. ([#64608](https://github.com/kubernetes/kubernetes/pull/64608), [@dixudx](https://github.com/dixudx))

### **OpenStack**

*   Remove the LbaasV1 of OpenStack cloud provider, currently only support LbaasV2. ([#52717](https://github.com/kubernetes/kubernetes/pull/52717),[ @FengyunPan](https://github.com/FengyunPan))

## Known Issues

    * NodeProblemDetector is a DaemonSet running on each node, monitoring node health and reporting node problems as NodeCondition and Event. Currently it already supports kernel log monitoring, and will support more problem detection in the future. It is enabled by default on gce now.
