The latest update 1.8 is going to be one for the map makers out there I have not really posted about this update because I'm not much of a map maker if at all. However they're adding some pretty cool stuff.
Notable added stuff:
Spectator mode
Iron trapdoors
Lots of new features for command blocks mainly for mapmakers.
Other than that there's not much more apart from a but load of bug fixes (I mean a lot of bug fixes). So there you go a shortened down version of the latest updates.
