minecraft 1.8 update

minecraft 1.8!

new mobs:

so far i have only heard of one new mob that is supposed to be very
creepy and tall and with long arms but so far i haven't heard a name
sorry if im wrong please comment if i am

features:
there are a few new features iv'e heard of but you probably know them
here they are

NPC villages,
more farming options,
randomely generated dungeons
and sprinting

and when he said randomely enerated dungeons i started thinking cause i was
deffinetely sure those were in the game already
so i did some research and all i found was that they would be either Harder or more rewarding
if you have the real answer please comment

so yeah these are all the facts i know up to today so thanks for reading.
