18w31a[1] is the third snapshot released for Java Edition 1.13.1, which adds some new features, changes some existing features, optimizes performance, and fixes many bugs.
Additions[]
General[]
- Added a concept of force-loaded chunks to the game, and a command (
/chunk
) to toggle force-loading on and off.
- Block tags
- Added the block tag
minecraft:underwater_bonemeals
.
Changes[]
Blocks[]
- Are now properly waterlogged.
Mobs[]
- Now have a 5% chance of dropping bone meal when killed.
- Now spawn only in rivers, oceans, or beaches.
Items[]
- When used in water of warm ocean biomes, it now has a chance to grow coral.
Command format[]
- The scoreboard operator
%=
was changed from using Java's native%
to usingMath.floorMod
. This causes the operator to use floored modulo instead of truncated modulo, so now-1 % 7
wraps to 6 instead of returning -1.[2]
- Functions
- Line numbers in function parse error logs now start with 1 (was 0).
General[]
- Performance has been optimized.
