19w03a is the fourteenth snapshot for Java Edition 1.14, released on January 16, 2019,[1] which adds composters.



  • Produces bone meal.
    • Using certain items on the composter has a chance to add 1 level of composting to the composter, up to 7 levels. After the composter reaches level 7, it will turn into level 8 which is the harvestable stage, yielding 1 bone meal when used.
    • Some composted items will be consumed without adding a level. The chance a level will be added depends on the quality of the item: larger or crafted items have a higher chance of adding a layer when used (e.g. Kelp has a low chance of about 10%, while pumpkin pie has a chance of 100%).
  • Crafted with 3 planks and 4 fences.



Barrels, blast furnaces, grindstones, smokers, and sweet berry bushes
  • Added sounds for the blocks or items.
Crops and nether wart
  • Added placement sounds.
  • Changed model and texture.
  • Now gives off light level 15.
  • Now scaffolding without blocks under it has a bottom that can be walked on.
  • Now possible to place scaffolding to the side, similar to how can be stacked upwards.
