Stairs

Stairs are a new block, found in Survival only after breaking down Coal. Instead of making the player jump, it simply lifts them half of a block and on top of the stair or the block after it. Upon being stacked by another, it becomes a full block. Breaking it down only gives you one instead of two, requiring the player to be resourceful. But if you stack a block on top of one single stair though, you will produce a full block.

In /indev/ mode, coal yields chunks that can be made into torches. Stairs are instead made with cobblestone, via crafting.
