Java Edition 19w03a

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

Additions

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 turns into level 8, which is the harvestable stage, yielding 1 bone meal when used.
- Some composted items are consumed without adding a level. The chance a level is 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.

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.
