TWM (87) and FVWM (93) are still maintained today.

  Don't forget CDE (93) and XFWM (96), still getting releases.

    Xfwm has been rewritten from scratch at least 2 times. I can't imagine there is any code left from the original releases. Plus it used to be a CDE clone and that was dropped around version 2 when it became a light Gnome clone.
