Changelog

Version: 2.1.3
Date: 2026-09-13
  Bugfixes:
    - Removing one tank from a connected group no longer spills fluid the rest of the
      group catches. Only what overflows the remaining tanks and pipes hits the ground

Version: 2.1.2
Date: 2026-09-08
  Features:
    - Destroying something that was holding fluid in barrels spills what was in them. A
      chest of oil barrels leaves one oil spill rather than nothing at all
    - Destroying a ripe yumako tree or jellystem lets go of the spores that picking it
      would have, and leaves its fruit on the ground to rot and give off as much again.
      Destroying anything holding fruit spills that too. Harvesting, by hand or by
      agricultural tower, is untouched: the fruit goes to whoever picked it
  Bugfixes:
    - Several spills from one wreck are thrown about a little instead of landing on the
      same tile with one hiding the others
  Changes:
    - Nothing happens on a planet that has no pollution of its own. Vulcanus, Fulgora,
      Aquilo and space platforms record nothing, so spills there sat on the ground doing
      nothing; none are made now, and any left over from an earlier version are cleared
      away
    - Wreckage puts nothing into the air by itself anywhere except Nauvis. On Gleba the
      spores come from the plants
    - Felling a tree no longer pollutes. Biters knocking trees down was putting pollution
      in places nobody had been, and a forest takes pollution out of the air rather than
      putting it in

Version: 2.1.1
Date: 2026-09-08
  Changes:
    - Water and steam are now recognised the same way everywhere. Nothing a player does
      changes, but the two lists behind it were kept in two places and could disagree

Version: 2.1.0
Date: 2026-09-08
  Other:
    - Update for Factorio 2.1
  Bugfixes:
    - Destroying anything that holds no fluid no longer breaks the game, which in 2.0 meant
      every chest, belt and biter
    - Loading a save made with an older version no longer breaks the game
    - Destroying a full chest pollutes for what was inside it again
  Changes:
    - A destroyed fluid wagon or fluid turret now spills what it was carrying

Version: 1.2.0
Date: 2024-09-15

    - Switch to real migrations instead of old "migration" code in control
