Read OP carefully
It is in beta stage so wait for stable release.

The initial post never said anything about deep sleep, not to mention plenty of features are working even though it is beta. So not sure how carefully reading OP is going to arrive at the same conclusion as you, especially when in the post it is written that everything is working except those that are specifically mentioned. The user you replied to had a point in wondering why questions on deep sleep were being ignored.
