Java Edition 13w01b

13w01b is the second snapshot for 1.5, and was released to fix some of the bugs and crashes in the 13w01a snapshot.

Blocks

 * Chests
 * All containers output a redstone signal when a Comparator is placed against it directly.
 * The strength of it depends on how full the container is.
 * This works with Trapped Chests as well, meaning it can provide two redstone signals with different causes at the same time.


 * Hoppers
 * Can now shift-click rails onto the block to empty Chest Minecarts.\


 * Locked Chests
 * Texture was changed with an additional redstone block.
