Changelog

Version: 1.2.0
Date: 2026-09-23
  Features:
    - New "Only count ghosts in this logistic network" option. When enabled, the combinator
      must stand inside a roboport's supply area, and only reports demand inside the
      construction area of that roboport's logistic network. Anywhere else it outputs
      nothing. This stops requests for items no
      robot can deliver. On by default for newly placed combinators. Existing combinators and
      blueprints made before this version keep reporting the whole surface.
  Bugfixes:
    - Ghosts left behind when an entity is destroyed are now counted.
    - Fixed the changelog not being shown in the in-game mod browser.

Version: 1.1.0
Date: 2026-09-03
  Changes:
    - In response to user requests, Ghost Combinator technology now requires Construction robotics
      and Circuit network instead of Logistic system and Production science pack. The combinator
      is available earlier.
    - Research cost is now derived from those two prerequisites: every science pack either of
      them needs, at the higher amount, for the higher of their cycle counts
      and times. The cost is recalculated after all other mods load, so overhaul mods that re-cost
      Construction robotics or Circuit network should carry this technology along with them.
  Bugfixes:
    - Added missing padding to the combinator window.
    - The mod no longer fails to load if another mod removes one of its prerequisite
      technologies.

Version: 1.0.0
Date: 2026-08-15
  Features:
    - Added an output mode selector. Each combinator now reports one kind of construction
      demand: Builds (entity ghosts), Tiles (tile ghosts) or Upgrades (upgrade planner
      requests). To see more than one at once, place several combinators and wire their
      outputs together - the circuit network adds the signals.
    - Tile ghosts are now tracked: landfill, concrete and its variants, stone brick, space
      platform foundation, and the Space Age soils.
    - Upgrade requests are now tracked, reported as the target item.
  Bugfixes:
    - Combinators built by a space platform were never registered and output nothing.
    - Entities whose placing item differs from their name reported an invalid signal
      (stone brick tiles reported "stone-path", which is not an item).
    - Surface data for deleted surfaces is now discarded instead of accumulating.
  Changes:
    - Existing saves are rebuilt from a one-time full surface scan on update. This also
      picks up ghosts placed before the mod was installed, which were never counted before.
      All existing combinators keep their current behaviour (Builds mode).
    - Added /gc-rescan to rebuild tracking on demand.
