* Ensure expected load balancer is selected for Azure ([#62450](https://github.com/kubernetes/kubernetes/pull/62450), [@feiskyer](https://github.com/feiskyer))
* fix the issue that default azure disk fsypte(ext4) does not work on Windows ([#62250](https://github.com/kubernetes/kubernetes/pull/62250), [@andyzhangx](https://github.com/andyzhangx))

- Fixed a bug in CEL's common.UnstructuredToVal where `==` evaluates to false for identical objects when a field is present but the value is null.  This bug does not impact the Kubernetes API.
