Java Edition 1.13.1

1.13.1 is an upcoming minor update, which will primarily add the ability for fish mobs to drop bone meal, allow coral to generate when using bone meal underwater, add dead coral, add a search bar in the world list, change the spawning conditions of squids, add the command, add tooltips to tropical fish buckets and fix bugs.

Additions

 * Blocks
 * Re-added punch-to-explode TNT using the  state (instead of the   state in 1.12)
 * Added dead coral
 * Dead variants of regular corals.
 * Can be placed on top of blocks.


 * Debug screen
 * Added to force a JVM crash, instead of a regular crash. However, currently it only triggers with right control.


 * Entities
 * Fish now have a 5% chance of dropping bone meal when killed.


 * Items
 * Bone meal used in water of warm ocean biomes now has a chance to grow coral.
 * Added tooltips to bucket of tropical fish.


 * World list
 * Added a search bar in the world list.


 * General
 * Added a concept of force-loaded chunks to the game, and a command to toggle force-loading on and off.
 * Added the block tag.

Changes

 * Blocks
 * Conduits are now properly waterlogged.
 * Coral
 * Can now be placed in air.
 * Unless adjacent to water, they will turn into dead coral after a short moment.
 * Purpur stairs
 * Can now be crafted using purpur pillars.


 * Command format
 * The scoreboard operator  was changed from using Java's native   to using  . This causes the operator to use floored modulo instead of truncated modulo, so now   wraps to 6 instead of returning -1.


 * Entities
 * Squids now spawn only in rivers, oceans, or beaches.


 * Functions
 * Line numbers in function parse error logs now start with 1 (was 0).


 * General
 * Performance has been optimized.
 * Improved the performance of liquids.
 * Improved the performance of rendering chunks
 * Improved the performance of spawning mobs
