While playing in 1.4.2 single player,waiting for the servers to be updated, I was working in my mind when i place some stairs next to the mine's stairwell ,so i dont have to waste energy and time jumping, and I noticed that the stairs was only 1/4 a whole block and the rest is half a block (stairs normally are 1/2 1 block 1/2 half bllock. I thought the texture was bugging out and tested it but it was true! The stairs connected with the other stair next to it making a corner stair! Is this new? I don't see it in the update list.
