SIG Node iterated on the ability to support more workloads with better performance and improved reliability.  Alpha features were improved around hardware accelerator support, device plugins enablement, and cpu pinning policies to enable us to graduate these features to beta in a future release.  In addition, a number of reliability and performance enhancements were made across the node to help operators in production.

### OpenStack

* Fix system container detection in kubelet on systemd. ([#26586](https://github.com/kubernetes/kubernetes/pull/26586), [@derekwaynecarr](https://github.com/derekwaynecarr))
    * This fixed environments where CPU and Memory Accounting were not enabled on the unit that launched the kubelet or docker from reporting the root cgroup when monitoring usage stats for those components.

 *
 * <p>"IPv4 mapped" addresses were originally a representation of IPv4 addresses for use on an IPv6
 * socket that could receive both IPv4 and IPv6 connections (by disabling the {@code IPV6_V6ONLY}
 * socket option on an IPv6 socket). Yes, it's confusing. Nevertheless, these "mapped" addresses
 * were never supposed to be seen on the wire. That assumption was dropped, some say mistakenly, in

   * copying non-null values only.

   * possibly replacing values that were previously non-null.
   *
   * @throws NullPointerException if {@code table} has a null key
   * @throws IllegalArgumentException if any of the provided table's row keys or column keys is not

* kubeadm: fix a bug where standard kubeconfig paths were searched even if the user provided /etc/kubernetes/admin.conf explicitly for commands that accept --kubeconfig, like kubeadm token. ([#71874](https://github.com/kubernetes/kubernetes/pull/71874), [@neolit123](https://github.com/neolit123))...

    * Old behavior:
      * environment variables explicitly whitelisted via --docker-env-metadata-whitelist were exported as `container_env_*=*`. Default is zero so by default non were exported
      * all docker labels were exported as `container_label_*=*`
    * New behavior:
      * Only `container_name`, `pod_name`, `namespace`, `id`, `image`, and `name` labels are exposed

In Python 3.10 there's also a **new syntax** where you can put the possible types separated by a <abbr title='also called "bitwise or operator", but that meaning is not relevant here'>vertical bar (`|`)</abbr>.

- Fixed a bug where a partial `EndpointSlice` update could cause node name information to be dropped from endpoints that were not updated. ([#108198](https://github.com/kubernetes/kubernetes/pull/108198), [@liggitt](https://github.com/liggitt))
