  * A stable client library release\_1\_2 is added. The library is [here](pkg/client/clientset_generated/), and detailed doc is [here](docs/devel/generating-clientset.md#released-clientsets). We will keep the interface of this go client stable.
  * New Azure File Service Volume Plugin enables mounting Microsoft Azure File

- Changed kuberc configuration schema. Two new optional fields added to kuberc configuration, `credPluginPolicy` and `credPluginAllowlist`. This is documented in [KEP-3104](https://github.com/kubernetes/enhancements/blob/master/keps/sig-cli/3104-introduce-kuberc/README.md#allowlist-design-details) and documentation is added to the website by [kubernetes/website#52877](https://github.com/kubernetes/website/pull/52877) ([#134870](https://github.com/kubernetes/kubernetes/pull/134870),...

* After a kubelet rotates its client cert, it now closes its connections to the API server to force a handshake using the new cert. Previously, the kubelet could keep its existing connection open, even if the cert used for that connection was expired and rejected by the API server.
