- Kubelet.exe on Windows now checks that the process running as administrator and the executing user account is listed in the built-in administrators group.  This is the equivalent to checking the process is running as uid 0. ([#96616](https://github.com/kubernetes/kubernetes/pull/96616), [@perithompson](https://github.com/perithompson)) [SIG Node and Windows]...

- Adds feature gate `NodeLogQuery` which provides cluster administrators with a streaming view of logs using kubectl without them having to implement a client side reader or logging into the node. ([#96120](https://github.com/kubernetes/kubernetes/pull/96120), [@LorbusChris](https://github.com/LorbusChris))

* Allow remote admission controllers to be dynamically added and removed by administrators.  External admission controllers make an HTTP POST containing details of the requested action which the service can approve or reject.

### Kubernetes Node system swap support

Every system administrator or Kubernetes user has been in the same boat regarding setting up and using Kubernetes: disable swap space. With the release of Kubernetes 1.22, *alpha* support is available to run nodes with swap memory. This change lets administrators opt in to configuring swap on Linux nodes, treating a portion of block storage as additional virtual memory.

- Updating kubelet permissions check for Windows nodes to see if process is elevated instead of checking if process owner is in Administrators group ([#111079](https://github.com/kubernetes/kubernetes/pull/111079), [@marosset](https://github.com/marosset)) [SIG Node and Windows]

## Dependencies

### Added
_Nothing has changed._

- Kubeadm: make sure the etcd static pod startup probe uses /health?serializable=false while the liveness probe uses /health?serializable=true&exclude=NOSPACE. The NOSPACE exclusion would allow administrators to address space issues one member at a time. ([#110744](https://github.com/kubernetes/kubernetes/pull/110744), [@neolit123](https://github.com/neolit123)) [SIG Cluster Lifecycle]

- Updating kubelet permissions check for Windows nodes to see if process is elevated instead of checking if process owner is in Administrators group ([#108146](https://github.com/kubernetes/kubernetes/pull/108146), [@marosset](https://github.com/marosset))

- Added a "reason" field to the "image_garbage_collected_total" metric, allowing administrators to differentiate between images that were collected for reasons "age" vs "space".

  previous releases. When this happens, a `LifecycleHTTPFallback` event is recorded
  in the namespace of the pod and a `kubelet_lifecycle_handler_http_fallbacks_total`
  metric in the kubelet is incremented. Cluster administrators can opt out of the
  expanded lifecycle handler capabilities by setting
  `--feature-gates=ConsistentHTTPGetHandlers=false` in `kubelet`.'
