What's new

Bug Fixes

  • Fixed a server crash caused by the World Cleaner and Force Clean command
  • Fixed a rare race condition in the Async System

New Features

  • Config is now split into a folder (config/lagshield/) with separate files for features and mob settings
  • /lagshield reload — reload all configs without restarting the server
  • Mob Spawn Controller — per-mob spawn control via mob_spawns.json. All mobs are auto-detected on startup. Set spawn weight, mob cap, and enable/disable individual mobs.
  • Tick Rate Controller — entities far from players tick less frequently, saving performance without removing them. Scales automatically with TPS.

Performance

  • Various internal optimizations reducing main thread overhead
