What do you mean by "updating?"  In tframe I modify a few functions like

     start <- function (x, ...) if (is.Ttframed(x)) start(tframe(x), 
...) else UseMethod("start")

If that can no longer be done then this is a serious fundamental change 
that breaks all my code. I hope that is not what you mean. I'm just 
going away for a week, but will follow up when I return.
