Items

 * When used in water of warm ocean biomes, it now has a chance to grow coral.

Command format

 * Scoreboards
 * 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.


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

General

 * Performance has been optimized.
