    <!--caution>
      <para>
        If you are upgrading JS60 from a previously installed old version,
        save all work and exit your GNOME Session if you have one running.
        Replacing the JS60 binary will cause the GNOME Shell to crash and return
        you to your display manager or TTY. After installing the new version,
        reinstall <xref linkend="gjs"/>. Polkit is unaffected.
