Changelog

Version: 2.6.0
Date: 15. 02. 2025
  Features:
    - Tile counting: blueprints now include concrete, refined concrete, stone brick, landfill and other tiles in output signals

    - Auto-update setting: optionally re-read blueprints on a configurable timer (0 = disabled by default)
    - New mod setting: toggle tile counting on/off
    - Linked containers now supported as blueprint source
  Optimizations:
    - Added C++ entity event filters — build/destroy handlers only fire for our combinator, not every entity in the game
    - All functions converted from global to local scope for faster Lua lookups
    - Entity-to-item name resolution is now cached (major speedup for large blueprints)
    - Combinator section management optimized: reuses existing section instead of destroy+recreate cycle
    - Leftover signal slots are properly cleared on update
