Sounds like one or more functions changed their required arguments
between 26 and 28.  You would probably need to dig in a little more to
get some more specifics.  If you are not inclined towards that, it's
probably easiest just to stop using 26 altogether (unless there is
some compelling reason you must keep using it).
