Surprised to find out that Chris is writing Taskjuggler3 from scratch, and this time, in Ruby:
TaskJuggler 3.x is a from-scratch rewrite of TaskJuggler. It’s currently in its infancy and only supports a minimum feature set. It is not intended for users yet.

There is a git repository in
in case you want to give it a look.
