 * **External documentation link:** The source link configuration has [changed](https://docs.gradle.org/current/userguide/upgrading_version_8.html#deprecated_invalid_url_decoding). 
     The remote URL is now specified using the `URI` class instead of the `URL` class.

-    ```text
+    ```kotlin
     remoteUrl.set(URL("https://github.com/your-repo"))

 * **Custom assets:** The [`customAssets`](dokka-html.md#customize-assets) property now uses collections of files 
   ([`FileCollection`)](https://docs.gradle.org/8.10/userguide/lazy_configuration.html#working_with_files_in_lazy_properties)
