Key takeaways

  • New command: /stopsound stops sounds for a player, either all of them, one sound source or one specific sound.
  • Performance: fixes server lag from mob pathfinding (MC-94438, MC-17630) and collisions (MC-100692), and a 20 to 30% drop in chunk generation speed (MC-98994).
  • Stability: fixes a crash when trading too many items at once (MC-96526) and world corruption when teleporting to an infinite Y coordinate (MC-100410).
