- Enabled in-place resizing of pod-level resources.  
  - Added `Resources` in `PodStatus` to capture resources set in the pod-level cgroup.  

    *   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

- API
  - Ingress resources are now available via `networking.k8s.io/v1beta1`. Ingress resources in `extensions/v1beta1` are deprecated and will no longer be served in v1.18. Existing persisted data is available via the new API group/version  ([#74057](https://github.com/kubernetes/kubernetes/pull/74057), [@liggitt](https://github.com/liggitt))

- Extended resources backed by DRA feature allowed cluster operator to specify `extendedResourceName` in `DeviceClass`, and application operator to continue using extended resources in pod's requests to request for DRA devices matching the DeviceClass.
  

- the following deprecated APIs can no longer be served:
  - All resources under `apps/v1beta1` and `apps/v1beta2` - use `apps/v1` instead
  - `daemonsets`, `deployments`, `replicasets` resources under `extensions/v1beta1` - use `apps/v1` instead
  - `networkpolicies` resources under `extensions/v1beta1` - use `networking.k8s.io/v1` instead

  - The following APIs are no longer served by default:

    - All resources under `apps/v1beta1` and `apps/v1beta2` - use `apps/v1` instead
    - `daemonsets`, `deployments`, `replicasets` resources under `extensions/v1beta1` - use `apps/v1` instead
    - `networkpolicies` resources under `extensions/v1beta1` - use `networking.k8s.io/v1` instead
    - `podsecuritypolicies` resources under `extensions/v1beta1` - use `policy/v1beta1` instead

* 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))

- Encryption of API Server at rest configuration now allows the use of wildcards in the list of resources.  For example, *.* can be used to encrypt all resources, including all current and future custom resources. ([#115149](https://github.com/kubernetes/kubernetes/pull/115149), [@nilekhc](https://github.com/nilekhc))

- Active watches of custom resources now terminate properly if the CRD is modified. ([#78029](https://github.com/kubernetes/kubernetes/pull/78029), [@liggitt](https://github.com/liggitt))
