Changelog

Version: 0.2.3
Date: 13.06.2026
  Changes:
    - Hydrocarbon Chunks can now be sourced two ways so the production line never clogs on a
      byproduct. A new "Carbonic Asteroid Crushing (Hydrocarbons only)" recipe produces chunks
      with no carbon output, so dedicating crushers to chunks no longer backs up carbon (and
      vice versa) — important on modded ground/pseudo-space planets where you cannot void
      excess into space. It yields 1 Hydrocarbon Chunk plus a 50% bonus chunk, and returns the
      carbonic asteroid chunk 20% of the time (matching the vanilla asteroid-crushing pattern).
  Balancing:
    - The dedicated hydrocarbon recipe out-yields the combined one (~1.9 vs 1.5 chunks per
      carbonic asteroid) precisely because it forgoes the carbon output — so both recipes stay
      worth using depending on whether you also need carbon.
    - The combined "Carbonic Asteroid Crushing (Carbon + Hydrocarbons)" recipe now drops
      Hydrocarbon Chunks at 75% chance and 2x amount (up from 50% / 1x) for players who consume
      both outputs and want maximum throughput.

Version: 0.2.2
Date: 11.06.2026
  Changes:
    - Synthetic Crude is now liquefied with steam in a chemical plant (1 Synthetic Crude +
      100 steam -> 1800 crude oil), mirroring vanilla Coal Liquefaction. The recipe now appears
      alongside the other oil-processing recipes in the Fluids tab.
    - Better Pumpjack and Better Pumpjack Mk2 can no longer be crafted at quality.
    - Added an alternative recipe: Synthetic Crude can be liquefied straight to petroleum gas
      (1 Synthetic Crude + 250 steam -> 990 petroleum gas), letting petroleum-only bases skip
      the refinery. Costs more steam than the crude recipe and yields less than fully cracking
      the crude path, so it trades throughput for simplicity.
  Balancing:
    - Space oil is now genuinely worth a dedicated platform. Synthetic Crude now processes into
      1800 crude oil per unit (up from 300).
    - Synthetic Crude now needs only 2 Hydrocarbon Chunks per unit (down from 4) and crafts in
      8 seconds (down from 15).
    - Hydrocarbon Chunks now come from a dedicated "Carbonic Asteroid Crushing (Hydrocarbons)"
      recipe (unlocked with Space Oil Synthesis) that drops them at 50% alongside carbon, instead
      of modifying the vanilla carbonic crushing recipe. This keeps existing crusher blueprints
      and other space mods/planets (e.g. Muluna) unaffected. Set crushers to this recipe to get
      chunks.
    - Synthetic Crude is now dense (5 kg): 200 fit in a single cargo pod, delivering
      360,000 crude oil to the surface per drop.
    - Eco-Friendly Pumpjack reworked: depletion rate halved (now 20x slower than vanilla, 5% net)
      and it gains a built-in +20% productivity bonus. It now squeezes meaningfully more total
      oil out of a patch, giving it a real identity beyond just being slow.
    - Better Pumpjack Mk2 module slots reduced from 4 to 3. It remains the fastest pump (4x);
      this reins in the beacon-fed single-pump-supplies-everything ceiling.
    - Better Pumpjack energy raised 170 -> 190 kW; Better Pumpjack Mk2 raised 420 -> 460 kW.
    - Better Pumpjack recipe cost raised slightly: steel-plate 20 -> 25, advanced-circuit 10 -> 15.

Version: 0.2.1
Date: 10.06.2026
  Changes:
    - Hydrocarbon Chunks can no longer be sent up by rocket. They must be synthesised into
      Synthetic Crude in space; only the Synthetic Crude is shipped down to the planet.

Version: 0.2.0
Date: 01.06.2026
  Features:
    - Upgrade planner now chains: Pumpjack → Better Pumpjack → Better Pumpjack Mk2.
  Changes:
    - Pumpjack tier speeds are now derived relative to the vanilla pumpjack in the final data
      stage, so they always hold even when another mod alters the vanilla pumpjack (e.g.
      Krastorio2 finite-oil): Better = 2× vanilla, Mk2 = 2× Better, Eco = 0.5× vanilla.
  Balancing:
    - Space Oil Synthesis: synthetic crude now yields 300 crude oil (down from 500).
    - Space Oil Synthesis inputs made cheaper: carbonic asteroid crushing now drops Hydrocarbon
      Chunks at 40% (up from 30%), and Synthetic Crude costs 4 chunks (down from 5).
    - Eco Pumpjack mining speed reduced from 1.0× to 0.5×: two Eco pumps equal one vanilla pump
      in output, but deplete the field ten times slower. Energy and depletion rate unchanged.
    - Better Pumpjack Mk2 energy usage raised from 300 kW to 420 kW.
  Recipe Reworks:
    - Better Pumpjack Mk2 crafting recipe replaced: now requires the Better Pumpjack as a base
      plus steel-plate (40), electric-engine-unit (12), processing-unit (8), and concrete (20).
      Removed module ingredients.
  Compatibility:
    - Space Age: Space Oil Synthesis technology now requires only space-science-pack (first
      rocket launch). Removed the metallurgic-science-pack (Vulcanus) requirement.
    - Krastorio 2: Better Pumpjack Mk2 recipe override updated to use kr-steel-beam,
      electric-engine-unit, kr-energy-control-unit, and concrete; energy raised to 420 kW.
  Bugfixes:
    - Fixed pumpjack collision_box on all three variants (Mk2, Mk3, Eco) to match the Factorio
      2.0 vanilla pumpjack. The mismatch broke the upgrade chain (pumpjack → Better Pumpjack).
    - Fixed Better Pumpjack (Mk2, Mk3, Eco) pipe connections not following entity rotation; pipe
      visuals and connection points now appear correctly for all four orientations.
    - Fixed item sort order so the Eco Pumpjack appears between Better Pumpjack and Mk2.
    - Fixed bop-synthetic-crude appearing in the extraction-machine item subgroup (alongside
      pumpjacks) instead of intermediate-product where it belongs.
    - Fixed all Eco Pumpjack descriptions stating it "depletes fields five times slower"; the
      actual figure is ten times slower.
    - Fixed all three pumpjack variants missing open/close sounds, hit-spark damage effects, and
      the drawing-box extension that keeps the horsehead animation from being clipped.
    - Renamed the space-side Hydrocarbon Synthesis recipe to "Space Hydrocarbon Synthesis" to
      make clear it is the space-only variant.
    - Fixed Space Oil Synthesis technology description omitting that ice asteroids are the water
      source needed for the space synthesis recipe.
    - Added missing tips-and-tricks entry for the Eco Pumpjack.
    - Krastorio 2: pumpjack stat scaling (Mk2 ×4, Mk3 ×8) now only activates when the finite-oil
      setting is enabled; with finite-oil off the default stats are used, preventing Mk2 from
      running at 4× vanilla instead of the intended 2×.
    - Krastorio 2: added missing pollution emissions overrides and recipe overrides for all
      three pumpjack variants.
    - Space Age: added heating_energy values for all pumpjacks for cold-planet survival.

Version: 0.1.7
Date: 27.05.2026
  Balancing:
    - Renamed Better Pumpjack Mk2 to Better Pumpjack and Mk3 to Better Pumpjack Mk2.
    - Better Pumpjack now extracts at exactly 2x vanilla speed (was 1.5x), energy 170kW.
    - Better Pumpjack Mk2 now extracts at exactly 4x vanilla speed (was 2.5x), energy 300kW.
    - Eco Pumpjack speed corrected to 1x (same as vanilla, was 0.9x), energy 55kW, drain 20%.
    - Krastorio 2: Better Pumpjack scales to 4x and Better Pumpjack Mk2 to 8x to stay
      meaningful relative to the K2 vanilla pumpjack baseline (mining_speed=2).

Version: 0.1.6
Date: 26.05.2026
  Balancing:
    - Mk2 now unlocks right after Advanced Oil Processing with chemical science only (250 count).
    - Eco Pumpjack now unlocks between Mk2 and Mk3: production science, 350 count.
    - Eco Pumpjack prerequisite changed from Advanced Oil Processing to Mk2.
    - Mk3 base game now requires utility science packs in addition to production science.
    - Mk3 Space Age variant now requires only space science packs (first space trip).
    - Space Oil Synthesis technology now gates behind metallurgic science pack (Vulcanus).

Version: 0.1.5
Date: 26.05.2026
  Bugfixes:

  Features:
    - Space Age: Added Hydrocarbon Synthesizer, a space-rated assembling machine.
    - Space Age: Carbonic asteroids now have a 30% chance to drop hydrocarbon chunks when crushed.
    - Space Age: New space oil synthesis chain: chunks and water into synthetic crude,
      then heat synthetic crude in a chemical plant to yield 500 crude oil per unit.
    - Space Age: Added bop-space-oil-synthesis technology.
  Compatibility:
    - Space Age: Pumpjacks Mk2, Mk3 and Eco restricted to atmosphere-bearing planets.
    - Space Age: Pumpjacks include heating energy for cold-planet survival.
    - Space Age: Mk3 and Eco technologies now require space-tier science packs.
