[opensuse-factory] delta ISO？

Hi, all, One simple question: do we still have delta ISO provided? Or it's been abandoned a long time ago before I join openSUSE? I can't find it at d.o.o, and the latest delta ISO news on line was for 11.1. Or I make my question more simple, I have a M3 ISO, I want to update it to beta1, what can I do? We still have wiki page telling delta ISO is good for testing purpose. If we drop that a long time ago, it's misunderstanding and will confuse users.
