Protocol version


13w10b is the fifteenth and final snapshot for Java Edition 1.5, and was released to fix some of the bugs and crashes in the 13w10a snapshot.[1]



Dispensers and droppers
  • Will now only fire once when they receive a redstone signal.
    • To fire again, the signal must be turned off and on again. (Previously they would fire whenever they had a signal and a nearby block changed.)


24 issues fixed

  • MC-151 – Pushing TNT with a piston and activating it at the same time duplicates it.
  • MC-266 – Placing a solid block near TNT and above redstone torch won't update the TNT.
  • MC-846 – Dispenser and dropper shooting out when updated.
