Changelog

Version: 1.2.13
Date: 08. 09. 2026
  Changes:
    - Updated the mod for Factorio 2.1. It now requires Factorio 2.1.13 or later; stay on 1.2.7
      for Factorio 2.0.
  Graphics:
    - Planned trees are now drawn with the mod's own sapling graphic instead of the base game's
      tree sprites, so changes to the base game graphics no longer affect the mod.

Version: 1.2.7
Date: 06. 09. 2026
  Major Features:
    - Added a tree planting tool, available from the shortcut bar from the start of the game.
      Drag over an area to plan a forest of trees on plantable ground, and construction robots
      plant them using tree seeds from the logistic network.
    - Trees planted with the tool are protected from pollution damage exactly like trees
      planted by hand.
  Features:
    - Planned trees are previewed as small tree ghosts rather than as seeds on the ground.
    - Alt-dragging with the tool cancels planned trees inside the selected area.
    - Planning and cancelling can both be undone with Ctrl+Z.
    - Added a "Planting grid spacing" per-player setting, from 1 to 4 tiles.
    - Added a "Planting pattern" per-player setting. Natural places trees with a noise
      driven scatter that thickens into groves and opens into clearings, with no grid left
      in the result; Grid keeps them on exact staggered rows.
    - Large selections are planted progressively instead of being rejected, so a whole
      island can be planted in one drag without stalling the game. Up to 50000 trees per
      selection.
    - A chat message reports when a large planting job starts and when it finishes, so a
      slow one does not look like nothing happened.
  Changes:
    - Trees are only planned on ground types that tree seeds accept, and never on space
      platforms.
    - Trees planted by the tool are not registered with agricultural towers, so a tower in
      range will not harvest them.
  Bugfixes:
    - Fixed that protected trees could still slowly turn grey from pollution, because only
      the leaf stage was being restored.
    - Fixed that trees planted by construction robots were never protected.
    - Fixed that trees destroyed by fire, biters or other mods were left in the tracking
      list until the next refresh.
    - Fixed that event handlers registered from two different places could silently replace
      each other.
    - Fixed the changelog not being parsed by the game due to an invalid format.
  Optimizations:
    - Removing a tree from tracking is now a constant-time operation instead of a scan of
      every tracked tree.
    - The refresh sweep now runs in bounded batches on a fixed schedule instead of every
      tick, so large forests no longer cause a tick spike.
    - Tree removal is now detected through a single destruction registration instead of
      four separate mining and death events.
