Minecraft's "Better Together" update, "the first big step toward unifying Minecraft for console, mobile and Windows 10," is now live. Originally revealed in June, the new version of the game enables cross-platform play between Windows 10, Xbox, mobile, and VR versions of the game, on "massive servers, with communities numbering in millions of players and eccentric minigames to suit every taste." 

Also on tap in the update are a host of new items, new world start and host options, game rules, and more. The "True Beauty of coarse dirt," which I guess is code for Minecraft blocks in 4K, is yours to behold for the first time ever, and Realm invite links can now be shared (although that's still a "coming soon" feature for the Xbox One).
