Protocol version


13w02b is the fourth snapshot for Java Edition 1.5, and was released to fix some of the bugs and crashes in the 13w02a snapshot.[1]



Activator Rails
  • Large/double chests can now release a redstone signal when connected to a Comparator depending on the number of stacks within.
    • Before, double chests would only emit a signal depending on how full each individual chest was (a double chest with only the top half full would emit a full signal from the side that the items were in).
  • Powering the block now also stops it from taking in items (see comparison between 13w02a and 13w02b).[3]
Trapped chests
  • Can now transmit signal downward through one block. This does not apply horizontally (through walls).[4]
