Place any gun in your turret to defend your base, A new ring road around the island to lead you to your favourite monument, Steam Rich Presence on your friends list and life stats added to the death screen as well as various other optimizations and improvements.
Let us know if there's more stats you want to see here in future updates!
The information that we show to your friends list is purposefully vague to limit the potential for griefing (we only show if you are in the menu, in a monument or in the wilderness), but the feature can be disabled entirely with the "global.richpresence" convar.
