Flexydually V1

Newer versions of Cura have removed the Flexydually toolhead from the choices. Is there a way to continue to use the toolhead without having to keep running the older version of Cura.

Bump! I have a Taz 5 with the Flexydually v1 toolhead and need some working firmware. Which version of Cura still has the v1 toolhead, and is there any reason not to go back to that version (i.e. what changed since then)?
