Changes

You can either mine "up", "down" or level when mining a tile. Only the last mining action is relevant to determine the direction the mine shaft will take.Mining up or down represents the equivalent of a 20 dirt [[slope]].

There are slight deviation deviations in slope (up to 1 "dirt") when a mine shaft progresses. so So, "level" is actually 0 slope, 1 , or -1.Note that when connecting two mine shafts, the direction of the mining is irrelevant. ; one floor will connect to the other floor and ceilings will likewise connect.
