Changelog

Version: 1.2.1
Date: 2026-10-30
  Bugfixes:
    - Fixed the mod failing to load on engine builds where the lava tile effect's texture list is
      named noise_textures instead of textures (space/data.lua: attempt to index field 'textures').
    - Fixed a crash when the solar station is first visited: the station's hidden power source was
      marked unminable with a property that is read only (LuaEntity::minable instead of minable_flag).

Version: 1.2.0
Date: 2026-10-08
  Compatibility:
    - Updated for Factorio 2.1 (factorio_version is now 2.1; this release does not load on 2.0,
      the 1.1.0 release is the one for 2.0). Science packs are item prototypes instead of tools,
      recipe category became categories, probability became independent_probability,
      fuel_category became fuel_categories, defines.inventory.assembling_machine_modules became
      crafter_modules, and linked fluidbox connections moved from entity.fluidbox to
      entity.add_fluid_box_linked_connection and entity.get_fluid_box_linked_connection.
  Bugfixes:
    - Fixed the heatsink and heatpump not receiving heat energy on 2.1. A recipe's ingredient now
      sets the machine's fluidbox filter, and linked ports only share fluid while their filters
      match, so the ingredients are pinned to their receivers' exact temperatures (160/800 for the
      heatsink, 40 for the heatpump).
    - Fixed the heatsink's steam and fluoroketone outputs showing a fluid mixing warning when
      connected to turbines and pipes. The output ports are now output-only like the vanilla heat
      exchanger's.
  Changes:
    - Deprecated the thermostat, since heat pipes can read their own temperature onto the circuit
      network natively. Existing thermostats (and item stacks of them) are converted to heat pipes
      automatically, along with their wire connections and configured signal. The recipe is
      hidden and no longer unlocked.

Version: 1.1.0
Date: 2026-10-07
  Bugfixes:
    - Fixed heat pipe ghosts (and real placements via robots/remote view) sometimes resolving to
      the superheated heat pipe item instead of a plain heat pipe, and then never being fulfilled
      since that item is uncraftable. The superheated pipe now places its own dedicated entity
      instead of reusing the plain heat-pipe entity, which is what caused the ambiguity. It reads
      as a normal heat pipe once placed and mines back into a normal heat pipe.
    - The superheated heat pipe item now has its proper name and a description.
    - Fixed the Electrolyte Terminal being unable to discharge once the network had run out of
      power. It was a tertiary consumer for its whole 520MW draw, so it could not get the power it
      needed to run the discharge that would have restored the network. The terminal itself is now
      a small (20MW) primary consumer, and charging is paid for by a hidden tertiary charger
      linked to it, so charging still only ever uses surplus power. A full charge still costs the
      same 1040MJ in total. Existing terminals are given their charger automatically.
    - Updated the heatsink tooltip: all four heat connections now feed the same machine.
    - Fixed the heatsink's water/coolant pipe connections silently getting no cover graphics due
      to referencing undefined globals instead of the intended util functions.
    - Fixed the solar station tips and tricks entry using a nonexistent item for its icon, and
      added its missing Polish text.
    - Fixed the Electrolyte Terminal's hidden generator charging its own 333MJ buffer from
      surplus power for a minute or two after a terminal was built, which showed up as a
      draw from the generator.
    - Fixed removing the special space tile not revealing the intended foundation underneath.
    - Hardened a few control.lua handlers against missing helper entities instead of erroring.
  Changes:
    - The surface around the solar station flows faster.
    - The tips and tricks entries now have simulations: flares passing a gun turret and a laser
      turret, the solar station, and a supercomputer venting heat through a heat pipe into a
      heatsink.
    - module-inserter is now an optional dependency instead of a required one.
    - halo-heatsink's 4 heat-pipe corners used to be split into two independently-heated
      networks (2 corners feeding the low-temperature side, 2 feeding the high-temperature
      side). They're now one real, shared heat network: all 4 corners feed the low-temperature
      receiver, which conducts to the high-temperature receiver through one ordinary internal
      heat connection between them. The fluid outputs stay completely separate, so there's no
      change to recipes, fluid boxes, or the building's footprint -- only how it's heated
      internally. Existing placed heatsinks are migrated to the new receiver layout, with their
      selected recipe preserved.
    - Split control.lua into per-feature files, mirroring the existing data.lua split.
