- Added driver-owned fields in `ResourceClaim.Status` to report device status data for each allocated device. ([#128240](https://github.com/kubernetes/kubernetes/pull/128240), [@LionelJouin](https://github.com/LionelJouin)) [SIG API Machinery, Network, Node and Testing]

    * [Huge pages](https://www.kernel.org/doc/Documentation/vm/hugetlbpage.txt) can now be used with empty dir volume plugin.
* Alpha support for pre-allocated hugepages ([#50859](https://github.com/kubernetes/kubernetes/pull/50859), [@derekwaynecarr](https://github.com/derekwaynecarr))

* The LocalStorageCapacityIsolation feature is beta and enabled by default.  The LocalStorageCapacityIsolation feature added a new resource type ResourceEphemeralStorage "ephemeral-storage" so that this resource can be allocated, limited, and consumed as the same way as CPU/memory. All the features related to resource management (resource request/limit, quota, limitrange) are available for local ephemeral storage. This local ephemeral storage represents the storage for root...

- Enabled use of pods with volumes and user namespaces. The feature gate...

      // independent of the initial capacity, except that it won't be lower than the threshold
      // computed from that capacity. Because the internal table is only allocated on the first
      // write, we won't see copying because of the new threshold. So it is always OK to use the
      // calculation here.

- New feature gate, ServiceIPStaticSubrange, to enable the new strategy in the Service IP allocators, so the IP range is subdivided and dynamic allocated ClusterIP addresses for Services are allocated preferently from the upper range.

- During device plugin allocation, resources requested by the pod can only be allocated if the device plugin has registered itself to kubelet AND healthy devices are present on the node to be allocated. If these conditions are not sattsfied, the pod would fail with `UnexpectedAdmissionError` error. ([#117738](https://github.com/kubernetes/kubernetes/pull/117738), [@swatisehgal](https://g...

          // there's a way around creating the separate sortedKeys array, and if we're allocating
          // one array of size n, we might as well allocate two -- to say nothing of the allocation

          for (int i = 0; i < size; i++) {
            // We're careful to put only K instances in.
