 *  New: `Challenge` includes all authentication parameters.
 *  New: Upgrade to BouncyCastle 1.60, Conscrypt 1.4.0, and Okio 1.15.0. We don't yet require
    Kotlin-friendly Okio 2.x but OkHttp works fine with that series.

    ```kotlin
    implementation("org.bouncycastle:bcprov-jdk15on:1.60")
    implementation("org.conscrypt:conscrypt-openjdk-uber:1.4.0")
    implementation("com.squareup.okio:okio:1.15.0")
    ```

    - A new option cloudConfigType has been added to the cloud-config file. Supported values are: `file`, `secret` and `merge` (`merge` is the default value).
    - To allow Azure cloud provider to read secrets, the [RBAC rules](https://github.com/kubernetes/kubernetes/pull/78242) should be configured.
