Changelog

Version: 1.3.11
Date: 12. 09. 2026
  Changes:
    - Updated the mod for Factorio 2.1. It requires Factorio 2.1.13 or later; stay on 1.3.10 for
      Factorio 2.0.
    - Trees can now be planted on sand as well, following Space Age 2.1, which added the sands to
      the ground its tree seed accepts. This applies with and without the expansion.
    - With Space Age installed, planned trees are drawn from the base game's tree artwork rather
      than the expansion's, so later changes to the expansion's graphics cannot break them.

Version: 1.3.10
Date: 12. 09. 2026
  Major Features:
    - Space Age is now optional. The mod runs on vanilla Factorio, growing its own trees from
      its own seed. With the expansion installed it still plants Space Age's trees from Space
      Age's seeds, as it always has.
  Features:
    - Without Space Age the mod adds its own Tree seed, craftable from 2 wood with no research
      needed. Construction robots plant with it just as they do with the Space Age seed, and it
      can be placed by hand.
    - Without Space Age, planted seeds grow. A seed becomes a sapling that passes through four
      sizes over ten minutes before it turns into a tree, rather than appearing fully grown.
    - Without Space Age, growing saplings absorb pollution in proportion to their size, and the
      amount is shown on the pollution graph.
    - Protected trees now say so when hovered. Saplings report how far along they are as well.
  Graphics:
    - Without Space Age, a planted tree matches the ground it stands on. Deserts grow desert
      trees and grassland grows lush ones, using the base game's own artwork.
    - Planned trees and saplings are drawn as a small version of the tree they will become,
      shadow included, instead of a placeholder shape.
    - Added an icon for the tree seed, used for the item, the planting tool and the shortcut.
  Changes:
    - Without Space Age, trees can only be planted on the same natural ground the Space Age tree
      seed accepts: grass, dirt, dry dirt and red desert. Sand, concrete, stone paths, refined
      concrete, landfill and ore are refused, whether planting by hand or with the tool.
    - Paving over a sapling or a planned tree removes it and returns the seed, instead of leaving
      it stranded on ground where it could never become a tree.
    - Modded terrain is not supported without Space Age; seeds are refused on tiles the mod does
      not know.
    - With Space Age installed, planting itself is unchanged. What is different is cosmetic:
      planned trees use the mod's own artwork, the planting tool and its shortcut have a new
      icon, and protected trees now carry a tag when hovered.
    - Without Space Age the mod follows the expansion's planting closely rather than copying it.
      A sapling is the mod's own entity rather than a real plant, so it grows through a fixed
      set of sizes instead of being grown by the game itself.

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.
