The 1.10 update has finally been released, featuring a few new hostile and neutral mobs, new blocks and a lot of world generation updates affecting villages and mineshafts.
The game difficulty has been set to 'hard' which in turn adds harmful effects to some mobs, and how frequently they spawn.
The Nether and End worlds will reset late tomorrow afternoon (14th June). If you left anything in these worlds, please remove them or they will be lost forever. (We won't offer any refunds on items you lose.)
