- Structured logging of NamespacedName was inconsistent with klog.KObj. Now both use lower case field names and namespace is optional. ([#117238](https://github.com/kubernetes/kubernetes/pull/117238), [@pohly](https://github.com/pohly)) [SIG API Machinery, Architecture and Instrumentation]

## Dependencies

- Fixed a regression in kube-proxy where it might refuse to start if given
  single-stack IPv6 configuration options on a node that has both IPv4 and
  IPv6 IPs. ([#121008](https://github.com/kubernetes/kubernetes/pull/121008), [@danwinship](https://github.com/danwinship)) [SIG Network]

- Aggregated discovery supports both `v2beta1` and v2 types and feature is promoted to GA. ([#122882](https://github.com/kubernetes/kubernetes/pull/122882), [@Jefftree](https://github.com/Jefftree))

  an external cloud provider that has been updated to support the feature,
  you can pass comma-separated dual-stack `--node-ips` to `kubelet` and have
  the cloud provider take both IPs into account. ([#120275](https://github.com/kubernetes/kubernetes/pull/120275), [@danwinship](https://github.com/danwinship))

  The possibility of borrowing means that the old metric `apiserver_flowcontrol_request_concurrency_limit` can no longer mean both the configured concurrency limit and the enforced concurrency limit. Henceforth it means the configured concurrency limit.' ([#113485](https://github.com/kubernetes/kubernetes/pull/113485), [@MikeSpreitzer](https://github.com/MikeSpreitzer))
