What's new

🐛 Fix

  • Fixed a rare client-side freeze that could occur while ModWhitelist scans and hashes installed mod files
  • SHA-256 file scanning is now performed asynchronously instead of blocking the Minecraft client thread, preventing connection timeouts on systems where scanning the mods folder takes significantly longer
  • Added client scan duration logging to make future scan-related issues easier to diagnose

🔧 Improvement

  • Mod scan responses are now sent only after the background file scan has completed, without blocking normal client rendering or network processing

This mod has no additional files
