conjunction with SIG Cloud Provider, is focusing on moving internal APIs that the OpenStack (and other providers) depends upon to staging to guarantee API stability. This work also included abstracting the in-tree Cinder API and refactoring code to the external Cinder provider to remove additional Cinder volume provider code.

Additional work was also done to implement an OpenStack driver for the Cluster API effort lead by SIG Cluster Lifecycle. For the external Cloud-Provider-OpenStack code, the...

* Move HighWaterMark to the top of the struct in order to fix arm ([#33117](https://github.com/kubernetes/kubernetes/pull/33117), [@luxas](https://github.com/luxas))

* add  `kubectl replace --raw` and `kubectl delete --raw` to have parity with create and get ([#79724](https://github.com/kubernetes/kubernetes/pull/79724), [@deads2k](https://github.com/deads2k))
* E2E tests no longer add command line flags directly to the command line, test suites that want that need to be updated if they don't use HandleFlags ([#75593](https://github.com/kubernetes/kubernetes/pull/75593), [@pohly](https://github.com/pohly))

  - `servicePort` -> `service.port.number` (for numeric values)
  - `pathType` no longer has a default value in v1; "Exact", "Prefix", or "ImplementationSpecific" must be specified

  Other Ingress API updates:
  - backends can now be resource or service backends

with which the Combined Work was made is also called the "Linked
Version".

  The "Minimal Corresponding Source" for a Combined Work means the
Corresponding Source for the Combined Work, excluding any source code
for portions of the Combined Work that, considered in isolation, are
based on the Application, and not on the Linked Version.

  The "Corresponding Application Code" for a Combined Work means the

- `kubectl delete` no longer scales down workload API objects before deletion.
  Users who depend on ordered termination for the Pods of their StatefulSets
  must use `kubectl scale` to scale down the StatefulSet before deletion.

- `kubectl run --env` no longer supports CSV parsing. To provide multiple environment
