Highlights

  • Major stability and diagnostics update for Minecraft 1.21.4.
  • Improved stutter, freeze, and tick-spike detection.
  • Added new classification categories:
    • Shader compilation
    • Disk I/O stalls
    • Entity overload
  • Improved /sa optimize so it can build a larger safe install plan instead of suggesting small install waves across multiple restarts.
  • Added dependency-aware optimization planning.
  • Added protection against missing dependencies, wrong loader files, incompatible mod combinations, duplicate installs, and unsafe candidates.
  • Fabric API is no longer treated as an optimization mod and will not be downloaded by /sa optimize.
  • Added log-tail caching to reduce disk reads during stutter detection.
  • Improved recent event retention so important severe/extreme events are kept longer.
  • Added JSON validation for internal rules and optimization databases.
  • Cleaned old command hints and outdated public-facing text.
  • Improved EN/RU localization consistency.
  • Reduced jar size by optimizing the mod icon.
