- Kubernetes API Go types removed runtime use of the `github.com/gogo/protobuf` library, and are no longer registered into the global gogo type registry. Kubernetes API Go types were not suitable for use with the `google.golang.org/protobuf` library, and no longer implement `ProtoMessage()` by default to avoid accidental incompatible use. If removal of these marker methods impacts your use, it can be re-enabled for one more release with...

* Removed the deprecated kubelet --configure-cbr0 flag, and with that the "classic" networking mode as well ([#34906](https://github.com/kubernetes/kubernetes/pull/34906), [@luxas](https://github.com/luxas))
* New client-go structure ([#34989](https://github.com/kubernetes/kubernetes/pull/34989), [@caesarxuchao](https://github.com/caesarxuchao))
