// A Cinder volume must exist before mounting to a container.
// The volume must also be in the same region as the kubelet.

- OpenStack Cinder CSI migration is now GA and switched on by default, Cinder CSI driver must be installed on clusters on OpenStack for Cinder volumes to work (has been since v1.21). ([#107462](https://github.com/kubernetes/kubernetes/pull/107462), [@dims](https://github.com/dims))

- When using the OpenStack legacy cloud provider, kubelet and KCM will ignore unknown configuration directives rather than failing to start. ([#109709](https://github.com/kubernetes/kubernetes/pull/109709), [@mdbooth](https://github.com/mdbooth))

- The in-tree cloud provider for OpenStack (and the cinder volume provider) has been removed. Please use the external cloud provider and csi driver from [cloud-provider-openstack](https://github.com/kubernetes/cloud-provider-openstack) instead.
