  - `apiserver_authorization_config_controller_last_config_info` metric after successfully loading the authorization configuration file.
  - `apiserver_encryption_config_controller_last_config_info` metric after successfully loading the encryption configuration file. ([#132299](https://github.com/kubernetes/kubernetes/pull/132299), [@aramase](https://github.com/aramase)) [SIG API Machinery, Auth and Testing]

- Kube-apiserver: the `--encryption-provider-config` file is now loaded with strict deserialization, which fails if the config file contains duplicate or unknown fields. This protects against accidentally running with config files that are malformed, mis-indented, or have typos in field names, and getting unexpected behavior. When `--encryption-provider-config-automatic-reload` is used, new encryption config files that contain typos after the kube-apiserver is running...

- Included an additional resource labeltransformation in on_operations_total metric which could be used for resource specific validations for example handling of encryption config by the apiserver.
