This page covers a development version that has a critical issue under certain conditions.
Mining an empty jukebox creates an invisible "Air" item. Interacting with the item will crash the game and likely delete the chunk the jukebox was in.[1]

13w01b is the second snapshot for Java Edition 1.5, released on January 4, 2013[2] to fix some of the bugs and crashes in the 13w01a snapshot.
Changes
Blocks
- 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.[3]
- This works with trapped chests as well, meaning it can provide two redstone signals with different causes at the same time.
- Rails can now be placed on top of hoppers, which allows emptying chest minecarts.
Fixes
From released versions before 1.5
- MC-302 – TNT explosion delayed until exiting and re-entering world.
- MC-1619 – Infinite rail duplication glitch.
- MC-3287 – Inconsistency with pistons pushing items.
- MC-3339 – Tile entity crashing bug.
From the previous development version
- MC-5711 – Removing a block with a redstone torch on it will not remove the redstone torch.
- MC-5721 – Crash when using new inventory features.
- MC-5728 – Infinite loop caused by a comparator (on subtractor mode) feedback loop.
- MC-5729 – Only one block disappears when an Iron Golem or Snow Golem or Wither is created.
- MC-5746 – TNT render blocks invisible.
- MC-5748 – You can place anything in a container or Minecart or Furnace Minecart with the Hopper.
- MC-5759 – New inventory mechanics can break crafting.
- MC-5768 – TNT explosions that destroy the chest being viewed causes a crash.
- MC-5773 – Breaking a chest with another player viewing the contents will kick that player out of the server.
- MC-5786 – Players could not smelt Nether quartz ore.
- MC-5789 – Yellow text object counter (displaying a 0).
