Changelog

Version: 3.0.5
Date: 2025-06-27
  Bugs:
    - the agricultural tower distance was euclidean instead of manhattan
      (circular, not square)
    - add anti-dependency on concreep-redux.
    - remove a debug message
  Changes:
    - make some minor performance optimisations

Version: 3.0.4
Date: 2025-06-24
  Bugs:
    - applied patch by Nihilistzsche (https://github.com/utoxin/concreep-redux/commit/b9b65f83a9e10b24802d4bc5abb5b943a208d120.patch)
      should fix agriculture tower creep.

Version: 3.0.3
Date: 2024/11/03
  Added:
    - Setting for working in a circle instead of a square while placing ghosts. (End result doesn't change, just the way it places ghosts.)
    - Settings for disabling creep on specific surfaces if Space Age is enabled. (Issue #34)
  Known Issues:
    - Concreep will happily overwrite farming / soil tiles, both natural and artificial. Until I can figure out a better solution, disabling creep on Gleba or other locations where you have those tile types is your best solution.

Date: 2024/10/28
  Added:
    - Settings to disable the automatic deconstruction of cliffs, rocks, and trees. (Issue #37, Requested by Blastinburn)

Version: 2.3.1
Date: 2024/04/07
  Changes:
    - Adjusted the lower bound on usable bots to zero, so that it won't place a single tile ghost if you have 0 bots in the network. (Issue #24, Reported by skofisk)
  Known Issues:
    - Space Exploration Compatability: When attempting to place space scaffolding, it will error once per tile, but the creep will progress. (Issue #1)

Version: 2.2.1
Date: 2024/03/14
  Changes:
    - Fixed slight mis-alignment with area creep. (Reported by: Violet_Scarelli)
    - Partially fixed issues with SE space surfaces, allowing 'asteroid' tiles to be upgraded into space platform.

Version: 2.2.0
Date: 2024/03/13
  Added:
    - Added a mode that allows you to select tile types based on logistics/construction area. (Suggested by: Violet_Scarelli)
  Changes:
    - Refactored the code to separate the various creep types into their own methods.
    - Partially fixed issues with SE space surfaces, allowing 'asteroid' tiles to be upgraded into space platform.
  Optimizations:
    - Removed redundant / unused code.
  Info:
    - When attempting to place space scaffolding, it will error once per tile, but the creep will progress.

Version: 2.1.1
Date: 2024/03/10
  Changes:
    - Added the idle bot logic mentioned in the 2.0.0 changelog. It will now limit bots used for construction based on this setting.
    - Additionally, each active roboport will limit how many ghosts it places, attempting to spread the work around between active roboports.
  Optimizations:
    - Removed redundant / unused code.
    - Improved looping logic to avoid early exits, allowing more processing per iteration.
  Info:
    - There may be minor issues with SE space surfaces, and placing tiles on asteroids. If you know of a way to improve this, I'd love to hear about it.

Version: 2.1.0

    - Updated required Factorio version to 1.1.49.
    - Starting laying groundwork for a new setting to control how many idle bots the mod is allowed to use. Currently, non-functional.

Version: 1.3.8
Date: 2020/03/05

    - Updated for Factorio 0.18

Version: 1.3.6
Date: 2019/10/30
  Added:
    - Added setting for using concreep logic for laying bricks.  On by default.
  Changes:
    - Concreep will finish paving an area before looking for tiles to upgrade.

Version: 1.3.5

  Bugfixes:
    - Fixed bug to make the intended change in v1.3.4 work properly.

Version: 1.3.4
Date: 2019/09/20
  Bugfixes:
    - Added additional checks to ensure roboport tile matching works safely, like if dectorio is removed mid-game.

Version: 1.3.3
Date: 2019/09/19
  Bugfixes:
    - Added additional check to prevent placing brick when none are in the logistic network.

Version: 1.3.2
Date: 2019/09/18

    - Concreep can also upgrade brick to concrete or reinforced concrete.
    - Added settings to upgrade brick or concrete.
  Fixed:
    - Restored replicating Dectorio and most other placed tiles
    - Concreep once again respects the range setting.

Version: 1.3.1
Date: 2019/08/26
  Fixed:
    - Fixed a crash when adding this mod to a pre-existing save

Version: 1.3.0
Date: 2019/08/25
  Added:
    - Concreep performs much better than ever before!
    - Concreep lays down reinforced concrete first, then regular concrete, then seeks out regular concerete to upgrade.
    - Concreep marks cliffs for deconstruction rather than autoremoves them using previous logic.

Version: 1.2.0
Date: 2017/12/28
  Added:
    - Concreep now autoremoves cliffs as concrete is laid down.  Right now it auto-deducts the cliff-explosives from the logistic network instead of delivering it via bot.  Hoping to change this in the future.
  Note:
    - A roboport may fail to remove cliffs if insufficient cliff-explosives are available, and it can be stuck in a state where it won't check again.

Version: 1.1.0
Date: 2017/12/15
  Added:
    - Updated for 0.16
    - Added option to scale back the range roboports will build concrete.
    - Added option to ignore already built tiles (Brick, asphault, etc)
