Changelog

Version: 2.1.0
Date: 2026-08-13
  Changes:
    - Updated to Factorio 2.1.
    - Depots now show a proper status in their GUI: working, no resource selected, no mining
      targets in range, missing required fluid, or no mining drones.
    - Depots handle being rotated: the bay, the drop off point and the mining area are rebuilt.
    - Depots built by script cloning are now registered and work.
    - Added get_depot_count, get_bonuses and reset_depots to the 'mining_drones' remote interface.
    - The mod setting and the technology effect descriptions can now be translated.
    - Disabled quality on the mining recipes.
  Bugfixes:
    - Fixed that mining drone productivity research did nothing. It has had no effect on the
      amount of ore delivered since the 2.0 update.
    - Fixed that the depot fluid box was converted to a hundredth of its old size in the 2.0
      update, so any resource needing more than 10 fluid could never be mined at all.
    - Fixed that a drone could be left standing in the field forever with no orders if the
      depot ran out of fluid at the exact moment it was being ordered.
    - Recipes for fluid gated resources now say which fluid they need.
    - Fixed that mining targets were never released when a depot was removed or had its recipe
      changed while it had queued path requests, which permanently reserved those ore entities
      so no other depot would mine them.
    - Fixed that the list of targeted resources was never cleaned up, growing forever as a patch
      was mined out.
    - Fixed that ore was silently destroyed when a drone came home to a depot with a full output.
      The drone now keeps what did not fit and waits.
    - Fixed that mining drones used the 'bullet' ammo category, so bullet damage upgrades were
      quietly speeding up mining. They now use their own category.
    - Fixed that the technology bonuses were cached in a way that could disagree with the force,
      for instance after a technology effects reset or a force merge.
    - Fixed that changing a depot recipe while path requests were queued could send drones of the
      new resource type to mine the old one.
    - Fixed a crash in the drone destruction handler that would have triggered if a drone was
      removed by another mod.
    - Fixed that the depot pipe graphics were rendered from the low resolution sheets.
    - Fixed that the drone smoke never faded out, and removed a pile of prototype properties that
      have not done anything since 2.0.
    - Removed the leftover proxy chest prototype, unused since 0.3.6.
    - Fixed that resources which mine into anything other than a plain item, which several mods
      use, got no mining recipe at all and so could never be mined by a depot.
    - Fixed that a depot kept using the force it was built on, so moving one to another force
      left it applying the wrong mining, walking, cargo and productivity bonuses.
    - Fixed that a depot kept the fluid requirement it first saw, so a mod update that changed
      what a recipe needs was ignored until the recipe was changed by hand.
    - Fixed that a single path request that never came back, which happens when its surface is
      deleted mid flight, permanently stopped every depot in the game from mining.
    - Fixed that a depot briefly reported itself as working when its recipe changed, and that it
      kept reporting itself as working when a rescan turned up nothing to mine.
    - Fixed that a mining drone joining a unit group destroyed the whole group, even when it
      belonged to another mod. Only groups made up entirely of drones are destroyed now.
    - Fixed that a resource asking for a fluid without saying how much of it broke the data stage.
  Optimizations:
    - Drone inventories are recycled instead of being created and destroyed for every mining trip.
    - Resources that only yield fluid, crude oil being the obvious one, no longer generate an
      attack proxy, four smoke prototypes and four pot animations that could never be reached.

Version: 0.3.1
Date: 2020-02-01

    - Added a startup mod setting to ignore rocks.
    - Changed how the depot hold resources, so it works smoother and has a large overflow buffer so you don't lose ore.
    - Reduced depot stack size to 5.
    - Increased each drone inventory size from 1 stack to 10 stacks (it only really matters with crazy high productivity).
    - Fixed an error when the script path request finished and the depot was destroyed.

Version: 0.3.0
Date: 2020-01-24
  Changes:
    - 0.18 update

Version: 0.2.1
Date: 2020-01-19
  Changes:
    - Fixed base game pathfinder crashes due to drone collision mask.
    - Fix error with missing attack proxy prototypes.
    - Fix error with some mods with certain tint definitions.

Version: 0.2.0
Date: 2020-01-13
  Changes:
    - Drones will now have a color matching the resource they are mining.
    - Fixed a desync with cyclic references and serpent serialisation.
    - Added a remote interface to get the number of active drones.
    - Tweaked the recipes, mining depot is a bit more expensive, drones are a bit cheaper.
    - Fixed mining things when resource prototypes change to require fluid midway through mining.

Version: 0.1.14
Date: 2019-12-28
  Changes:
    - Fixed that script path requests could say "try again later" and I would just not handle it. This should fix more cases of entities being mined out of order.

Version: 0.1.13
Date: 2019-12-28
  Changes:
    - Changed the target picking logic to help prevent drones mining things out of order.
    - This is also potentially a fix for some desyncs related to large lists. Serpent serialises them differently depending on length, and this fixes it (hopefully?).

Version: 0.1.12
Date: 2019-12-27
  Changes:
    - Changed the logic around when to spawn drones, so now its proportional to how full the depot is. Basically, if it is half full, it will send at most half of its drones.
    - Further attempts to stop dudes getting stuck on things.

Version: 0.1.11
Date: 2019-12-25
  Changes:
    - Optimized the resource searching logic, so extreme patches won't take 5 minutes to process.

Version: 0.1.10
Date: 2019-12-17
  Changes:
    - Fix not cleaning up proxy chests used for inventory management, leading to performance drops over time.

Version: 0.1.9
Date: 2019-12-16
  Changes:
    - Fixed that natural evolution enemies would make the drones drop alien poop.

Version: 0.1.8
Date: 2019-12-16
  Changes:
    - Switch to using a corpse for the 'caution plate' sprite.
      This lets the return path target an entity which has some internal engine logic to make the pathing work smoother.

Version: 0.1.7
Date: 2019-12-16
  Changes:
    - Drastically reduce cost of mining depot.
    - Rebalance cost of mining drone (More plate, but less gears and sticks), and reduce recipe time.
    - Fixed spazziness of drone mining resource on the deploy pad.

Version: 0.1.6
Date: 2019-12-15
  Changes:
    - Fix mining drones removing ghosts on top of the mining targets. (This needs a migration, so lots of drones will stop working briefly.)

Version: 0.1.5
Date: 2019-12-15
  Changes:
    - Make the dudes immune to belts. They kept getting stuck, and didn't add anything to the fun.
    - Lowered the mining sound volume a bit.
    - Fixed a startup crash due to some other mod.

Version: 0.1.4
Date: 2019-12-14
  Changes:
    - Try to stop drones suiciding so much.
    - And if they do suicide, they won't make an alert...

  Changes:
    - Fixed depleting infinite resources.

Version: 0.1.2
