18w31a is the third snapshot for Java Edition 1.13.1, released on August 1, 2018[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 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 % 7wraps 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.
