Data version


19w36a is the third snapshot for Java Edition 1.15, released on September 4, 2019,[1] which adds many features originally from Bedrock Edition.


Command format[]



  • Added minecraft:beehive_inhabitors entity tag.



  • Trying to sleep in a bed during the daytime will now set the player's spawn location to that bed.
Bee hives
  • Will now ring if powered with a redstone signal.
  • Firework rockets dispensed from a dispenser now travel in the direction they were fired.
Wet sponges


Honey bottles




  • Obfuscation maps are now published with all future versions of the game, including this one.
    • Does not change the existing restrictions on what may or may not be done with game code or assets.
    • Links to the obfuscation mappings are included in the version's accompanying .json file.
Chunk format
  • Biome information now is stored in sixty-four 4×4 arrays, allowing biomes to be changed based on height; previously, biome values corresponded to only the X and Z coordinates.
    • The  Biomes array in the  Level tag for each chunk now contains 1024 integers instead of 256. Each number in the array is the biome for a 4x4x4 volume in the chunk. These 4×4×4 volumes are arranged by Z, then X, then Y. That is, the first 4×4 values in the array are for the 16×16 chunk, at Y-levels 0–3, the next 4×4 is for Y-levels 4–7, etc.
