-            Added support for APK signature scheme v4:
+            **Android APK signature scheme v4** support added:
             * The signing directive `<apk-sign>` has been replaced with [`<create-apk-signature>`](/artifact-configuration/reference#create-apk-signature).
             * Because a v4 signature is added as a separate `.idsig` file, the `<apk-file>` element must be nested in a container such as a ZIP archive.
             * For compatibility reasons, the legacy `<apk-sign>` directive still exists, but will be removed in a future version (in this case no ZIP archive is required).
