- [PR #9764][fossedihelm] Cluster admins can enable ksm in a set of nodes via kv configuration
- [PR #9753][lyarwood] The following flags have been added to the `virtctl image-upload` command allowing users to associate a default instance type and/or preference with an image during upload. `--default-instancetype`, `--default-instancetype-kind`, `--default-preference` and `--default-preference-kind`. [See the user-guide documentation](https://kubevirt.io/user-guide/virtual_machines/instancetypes/#inferfromvolume) for more details on using the uploaded image with the `inferFromVolume` feature during `VirtualMachine` creation.
- [PR #9575][lyarwood] A new `v1beta1` version of the `instancetype.kubevirt.io` API and CRDs has been introduced.

- [PR #9747][lyarwood] action required - With the `v1.0.0` release of KubeVirt the storage version of all core `kubevirt.io` APIs will be moving to version `v1`. To accommodate the eventual removal of the `v1alpha3` version with KubeVirt >=`v1.2.0` it is recommended that operators deploy the [`kube-storage-version-migrator`](https://github.com/kubernetes-sigs/kube-storage-version-migrator) tool within their environment. This will ensure any existing `v1alpha3` stored objects are migrated to `v1` well in advance of the removal of the underlying `v1alpha3` version.

- [PR #9628][lyarwood] * The `kubevirt.io/v1` `apiVersion` is now the default storage version for newly created objects
- [PR #8293][daghaian] Add multi-arch support to KubeVirt. This allows a single KubeVirt installation to run VMs on different node architectures in the same cluster.
