- Kubernetes cannot distinguish between GCE Zonal PDs and Regional PDs with the same name. To workaround this issue, precreate PDs with unique names. PDs that are dynamically provisioned do not encounter this issue. ([#70716](https://github.com/kubernetes/kubernetes/pull/70716), [@msau42](https://github.com/msau42))

## Known Issues

- CSI Migration: GCE PD access mode now reflects read only status of inline volumes - this allows multi-attach for read only many PDs ([#84809](https://github.com/kubernetes/kubernetes/pull/84809), [@davidz627](https://github.com/davidz627))

* Add storage-backend configuration option to kubernetes-master charm. ([#58830](https://github.com/kubernetes/kubernetes/pull/58830), [@wwwtyro](https://github.com/wwwtyro))

* Fixed dynamic provisioning of GCE PDs to round to the next GB (base 1000) instead of GiB (base 1024). ([#56600](https://github.com/kubernetes/kubernetes/pull/56600), [@edisonxiang](https://github.com/edisonxiang))
