App_Details: V2.5.3 (B227)!,

Use the tag above to indicate the app info followed by the version string. This must be an exact match to the version string used by the App. Vn.n.n (Bn) where n represents digits. If there is a ‘!’ at the end of the version string, after the closing parenthesis, then the app will force the upgrade (will not function till updated). The entry after the ‘,’ is the URL used to install the new build. This expects an href tag.
