Hey there
Unfortunately there’s no update right now. It’s still in Alpha phase as there can be some bugs here and there. Happy to send you a link so you could try it on a dev site though.
We’re currently more focused on making our projects work with Gutenberg, the new block editor that’s coming to WordPress 5.0. But of course we want to finally get 2.0 out of the door just as much as our users do.
Can you perhaps elaborate a bit on role based options? Anything in particular you’d like being able to do?
Right now in 2.0 each user can modify the admin menu to their own liking, but there’s probably gonna be an option to change the menu globally for all users as well.
