What's new

V6.0.0 Changelog

  • Improved performance: Reduced repeated area scanning, limited container-checking workloads and improved handling of busy multiplayer areas.
  • Simpler setup: Crouch and use a reusable clock to open setup and administration.
  • Cheat-free administration: Cheats, experiments and manual admin-tag commands are no longer required for normal setup.
  • Secure staff access: Added operator-controlled enrollment, PIN login, access revocation and persistent login lockouts.
  • Stronger transfer protection: Improved bundle, hopper, dropper and hopper-minecart checks, including while container menus are open.
  • Safer join/leave checks: Replaced the old full-cursor rule with item-total comparisons to identify excess items.
  • Clearer reporting: Automatic or uncertain detections are recorded without assigning player violations or public accusations.
  • Updated guidance: Rewritten setup instructions and feature explanations for easier use.
