Changelog

Version: 2.7.2
Date: 28. 02. 2025
  Bugfixes:
    - Fixed crash when reading blueprints containing machines with modules (entity.items format handling for Factorio 2.0)

Version: 2.7.1
Date: 28. 02. 2025
  Bugfixes:
    - Fixed entity sprite scale — now matches vanilla constant-combinator size (scale 0.28)
    - Fixed sprite direction mapping — default placement (north) now correctly shows front view
    - Fixed shadow opacity — shadows were nearly invisible (alpha 44/255), now properly visible
    - Fixed shadow shape and direction — generated programmatically from entity silhouettes, extends to the right matching vanilla shadow style
    - Added custom circuit_wire_connection_points for all 4 directions — wire attach points now match visual connector positions on each rotation

Version: 2.7.0
Date: 28. 02. 2025
  Features:
    - Custom original graphics — unique entity sprites, item icon, technology icon and thumbnail
    - Module counting — pre-inserted modules inside blueprint machines are now included in output signals
  Optimizations:
    - Settings values (count-tiles) are now cached and updated via on_runtime_mod_setting_changed instead of read every tick
    - Quality list is cached after first access (reset on configuration change)
    - on_nth_tick cleanup now targets only own handler instead of clearing all nth_tick registrations
    - Safe table iteration — invalid entries collected first, removed after loop completes
    - Simplified process_blueprint_reader — single set_combinator_signals call instead of duplicate branches
  Bugfixes:
    - Removed unused elevated-rails optional dependency
    - Renamed internal variable from tinted_icons to item_icons (no longer uses tinting)
  Changes:
    - Replaced all base game constant-combinator graphics with custom artwork
    - Entity sprites use proper spritesheet (512x128) with separate shadow layer
    - Technology icon shows device alongside its crafting recipe components
    - Updated FAQ and README to reflect custom graphics and module counting

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
    - Nested blueprint book support: recursively reads active blueprints from books-within-books
    - 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
  Bugfixes:
    - Quality settings button no longer appears on regular constant combinators (only on Blueprint Reader)
    - Fixed missing migration: existing combinators are now re-registered on mod update/configuration change
    - Invalid entity references are cleaned up automatically
    - Removed unused storage.player_data
  Changes:
    - Removed redundant icon/icon_size fields where icons array was already defined
    - Simplified sprite tinting code
    - Settings changes (auto-update interval) apply immediately without game restart
