- The dockershim now sets the "bandwidth" and "ipRanges" CNI capabilities (dynamic parameters). Plugin authors and administrators can now take advantage of this by updating their CNI configuration file. For more information, see the [CNI docs](https://github.com/containernetworking/cni/blob/master/CONVENTIONS.md#dynamic-plugin-specific-fields-capabilities--runtime-configuration) ([#64445](https:...

- `StatefulSet` names must be DNS labels, rather than subdomains. Any `StatefulSet`
  which took advantage of subdomain validation (by having dots in the name) can't

- Makes locally attached (non-network attached) storage available as a persistent volume source.
- Allows users to take advantage of the typically cheaper and improved performance of persistent local storage

The dynamic kubelet config feature graduated to beta, so it is enabled by default, simplifying management of the node object itself.  Kubelets that are configured to work with the CRI may take advantage of the log rotation feature, which is graduating to beta this release.

*   Block Storage (Cinder) V3 is now supported.

This work enables Kubernetes to take full advantage of the relevant services as exposed by OpenStack clouds. Refer to the [Cloud Providers](https://kubernetes.io/docs/concepts/cluster-administration/cloud-providers/#openstack) documentation for more information.
