ok, so i feel that a lot of people are WAAYYYYYY to hyped up about 1.6, and a lot of them are saying things that contradict each other. therefore, im going to list what i know about it. if you want to contradict me, agree with me, have an idea, or whatever, just reply. List: horses hay bales and.... those are the only things i've heard of that haven't been contradicted. please reply
