- kubeadm: Improved `kubeadm init` and `kubeadm join` to provide consistent error messages when the kubelet failed or when failed to wait for control plane components. ([#130040](https://github.com/kubernetes/kubernetes/pull/130040), [@HirazawaUi](https://github.com/HirazawaUi))

- We will no longer automatically delete all data when a failure is detected during creation of the volume data file on a CSI volume. Now we will only remove the data file and volume path. ([#96021](https://github.com/kubernetes/kubernetes/pull/96021), [@huffman...

  * The `--audit-policy-file` option is required if the `AdvancedAuditing` feature is not explicitly turned off (`--feature-gates=AdvancedAuditing=false`) on the API server.
  * The audit log file defaults to JSON encoding when using the advanced auditing feature gate.
  * An audit policy file without either an `apiVersion` or a `kind` field may be treated as invalid.
  * The webhook and log file now output the `v1beta1` event format.

* Fix image file system stats for windows nodes. ([#59743](https://github.com/kubernetes/kubernetes/pull/59743), [@feiskyer](https://github.com/feiskyer))

* Kubernetes will now return an error if New-SmbGlobalMapping failed when mounting an azure file on Windows. ([#59540](https://github.com/kubernetes/kubernetes/pull/59540), [@andyzhangx](https://github.com/andyzhangx))

- kube-apiserver now reloads the `--authorization-config` file when it changes. Reloads increment the `apiserver_authorization_config_controller_automatic_reload_last_timestamp_seconds` timestamp metric, with `status="success"` for successful reloads and `status="failed"` for failed reloads. Failed reloads keep using the previously loaded authorization configuration.

- Kube-log-runner: rotating log output into a new file when reaching a certain file size can be requested via the new `-log-file-size` parameter. `-log-file-age` enables automatical removal of old output files.  Periodic flushing can be requested through ` -flush-interval`. ([#127667](https://github.com/kubernetes/kubernetes/pull/127667), [@zylxjtu](h...
