* fixes a bug around using the Global config ElbSecurityGroup where Kuberentes would modify the passed in Security Group. ([#49805](https://github.com/kubernetes/kubernetes/pull/49805), [@nbutton23](https://github.com/nbutton23))
* Updates Cinder AttachDisk operation to be more reliable by delegating Detaches to volume manager. ([#50042](https://github.com/kubernetes/kubernetes/pull/50042), [@jingxu97](https://github.com/jingxu97))

### **OpenStack**

*   OpenStack Cinder support has been improved:
    *   Cinder version detection now works properly. ([#53115](https://github.com/kubernetes/kubernetes/pull/53115),[ @FengyunPan](https://github.com/FengyunPan))

 - OpenStack Cinder CSI migration is on by default, Clinder CSI driver must be installed on clusters on OpenStack for Cinder volumes to work. ([#98538](https://github.com/kubernetes/kubernetes/pull/98538), [@dims](https://github.com/dims)) [SIG Storage]
