Wondering if Ag skies is taking the back burner on development to the farm thing she does? She talk's about the other one on her twitter a lot more than ag skies, which hasn't been talked about lately.
As far as I know, Agrarian Skies 2, along with Jadedcat's recent personal modpacks, are only available in the Curse launcher for now. You can download it at http://beta.cursevoice.com/
