The final chapter is being worked on while I add other stuff, so it's slowly getting there. If I just focused on it, I think I could wrap it up in 1-2 months. I am considering making a push for it at least, so maybe in 3-4 months I can have most of what I want/need for a 1.0 release in place. I might actually focus more on finishing the final chapter first, and then add some of the remaining stuff, we'll see. Anyway, I think we are getting there.
