This is a great Phoenix release!
Having auth built in has been one of my most wanted features for a long time and I think will help make it easier to build packages that make use of the unified system 
It’s also great to see LiveView becoming more and more refined with each release 
I am not sure whether there are any immediate plans for it, but I might wait to get back into reading Programming Phoenix until it is updated for 1.6 (I’ve still got Programming Erlang to finish first! 
)
