    * Note: for this change, the other allocators still exist and are the default.
    * It supports two modes:
        * CIDR range allocations done within the cluster that are then propagated out to the cloud provider.
        * Cloud provider managed IPAM that is then reflected into the cluster.
* Alpha list paging implementation ([#48921](https://github.com/kubernetes/kubernetes/pull/48921), [@smarterclayton](https://github.com/smarterclayton))

- Kube-proxy: delete stale conntrack UDP entries for loadbalancer...

Volume cloning enables users to specify another PVC as a "DataSource" when provisioning a new volume. If the underlying storage system supports this functionality and implements the "CLONE_VOLUME" capability in its CSI driver, then the new volume becomes a clone of the source volume.

These changes are reflected in the following Kubernetes enhancements:
([#625](https://github.com/kubernetes/enhancements/issues/625))

There is also a new way to run bleeding edge Windows features from scratch by compiling the windows kubelet and kube-proxy, then using them along with daily builds of other Kubernetes components.
