Changelog

Version: 0.3.7
Date: 2026-10-24
  Features:
    - Recover 5 alumina or 10 silica from 10 purified mineral residue, 10 sulfuric acid and 20 water in 10 seconds, retaining the ordinary mineral tailings. Each optional route requires the pack's existing oxide production and has fixed yields without productivity, quality or automatic recycling.

Version: 0.3.6
Date: 2026-10-24
  Features:
    - Add optional phosphoric-acid gallium extraction with the same yield and 20% longer processing time. Material packs using caustic leachate recovery retain their required chain.
    - Use arsenic oxide to fine glass or make poison capsules with 25% more output from the ordinary ingredients.
    - Use arsenic instead of phosphine to make existing doped silicon. Native silicon and argon requirements are preserved.
  Compatibility:
    - New alternatives follow their host research, respect recipe bypasses and preserve the original recipes and recycling basis.

Version: 0.3.5
Date: 2026-10-23
  Changes:
    - Require Factorio 2.1.23 or later in the 2.1 series.
    - Mention Brevven's BZ mods in the searchable summary.

Version: 0.3.4
Date: 2026-10-23
  Bugfixes:
    - Exclude Transport Drones delivery selectors from manufacturing integrations, preventing oversized semiconductor ingredient amounts and startup crashes.
    - Preserve delivery capacity, fuel requirements and recipe availability; ordinary processor manufacturing keeps its existing semiconductor cost.

Version: 0.3.3
Date: 2026-10-17
  Changes:
    - Connect external crystal factories through chemical preparation, foundry GaAs, circulating crucibles and wafer-finishing supplies.
    - These integration additions leave Fluffy-only recipes, machines and progression unchanged, with or without Space Age.
  Compatibility:
    - Coordinate Tellurium's external material chains and save-safe recipe upgrades; Fluffy-only gameplay remains unchanged.

Version: 0.3.2
Date: 2026-10-17
  Compatibility:
    - Refresh Cadmium 0.5.0 material chains, old recipe assignments and recycling after final family bills.

Version: 0.3.1
Date: 2026-10-17
  Changes:
    - Preserve final Phosphorus material-pack bills and buffered save inputs.

Version: 0.3.0
Date: 2026-10-16
  Features:
    - Material packs now require native chemical and mechanical supply chains: quicklime purification, caustic leaching with graphite recovery, nitric/manganese arsenic extraction and chemical-waste handling where reachable.
    - Early BZ foundries compound GaAs. Argon and reusable crucibles prepare solid growth charges; nucleation, growth and selection return the crucibles without extra productivity or quality gains.
    - External packs use phosphoric acid and Neodymium polishing powder in wafer finishing, native solder and nylon in electronics, and native alloys, motors, bearings, flow controllers, nylon parts and diamond in machinery. Fluffy-only recipes and research stay unchanged.
  Compatibility:
    - Integrations prove feedstocks and constructible machines at every research unlock, joining acyclic parallel research at the existing science tier. K2, Space Exploration and Space Age retain their native electronics and orbital rules.
    - Space Age with Planetfall uses one zirconia instead of unreachable tungsten carbide in starter machining tools, preserving the motor, articulator, drive belt, output and crafting time.
    - Existing boosted extraction and discounted machine IDs become hidden equal-bill aliases when the corresponding required chain activates.
  Changes:
    - Upgrade from 0.2.1 preserves old recipe inputs, recipe selections, blueprints and research. Displaced fluids move to nearby recovery tanks, with a retry queue when space is unavailable. Chemical GaAs lines need rebuilding in a foundry when that integration activates.

Version: 0.2.1
Date: 2026-10-12
  Compatibility:
    - Paracelsin has optional zinc purification with a 20% chance of 1 purified mineral residue and tetrahedrite processing with a 10% chance of 1 arsenic oxide. Both preserve the original ingredients, products, 4-second duration and pressure limit.
    - Paracelsin trace mineral recovery follows Gallium and arsenic recovery and zinc extraction. Produce 20 dirty zinc solution to unlock both routes without consuming gallium or arsenic.
    - Zinc purification keeps its fixed yields and returned copper cable cannot gain quality or productivity. Both recovery processes are excluded from automatic recycling.

Version: 0.2.0
Date: 2026-10-12
  Features:
    - Gleba can make its own semiconductor feedstock: leach 20 stone with 1 iron bacterium and 20 water into 4 purified mineral residue in 10 seconds in a biochamber. Gallium bioleaching unlocks after recovery and Jellynut by crafting 10 iron bacteria.
    - Arsenic reduction can use 1 carbon instead of 1 coal for the same 4 arsenic from 2 arsenic oxide.
    - Vulcanus copper smelting can recover arsenic oxide with a 10% chance per batch. The 20-second process uses 500 lava and 1 calcite, keeping 250 molten copper and 15 stone. With Tellurium, its lava recovery recipe supplies both byproducts after joint research.
    - Platforms can crush metallic asteroids for trace minerals: 1 chunk yields 10 iron ore and 2 purified mineral residue in 3 seconds, with a 20% chunk return. Meteoritic gallium follows orbital growth and advanced asteroid processing.
    - Infinite semiconductor productivity adds 10% per level to gallium refining, GaAs synthesis, scrap recovery and all wafer finishing routes. It uses red, green, blue, space and electromagnetic science. Seed and boule yields stay fixed.
  Changes:
    - Foundries can synthesize GaAs. Electromagnetic plants can build both Gallium solar panels. Cryogenic plants can run Gallium chemistry alongside the original chemical plants.
    - Dry platform wafer finishing now gains productivity, including research bonuses, while retaining its fixed speed and normal-quality output.
    - With Space Age, Gallium recipes that return their own input no longer roll quality, including ash returns and self-recycling. Quality remains available when finishing wafers and manufacturing equipment.
    - Aquilo still needs imported gallium or Galinstan for its first cryogenic plant and imported semiconductor feedstock for quantum processors.

Version: 0.1.12
Date: 2026-10-12
  Bugfixes:
    - Fix the load error "No categories defined" for bioluminescent-gallium-crystal-puller with Tenebris Prime. Tenebris Prime no longer makes bioluminescent variants of the crystal pullers and the precision slicer, which would skip the seed and orbit rules. Variants already built in a save become the ordinary Gallium machines.
    - Crystal pullers that a space platform builds from a ghost now need an installed seed, like any other puller. Before, a blueprinted orbital puller without seed modules ran until someone opened it.
    - The Recycling research lists processing unit, cryogenic plant and quantum processor recycling once instead of twice.
  Changes:
    - The orbital crystal puller can only be placed on space platforms, the only place where it works.
    - The cryogenic plant's description and a new Space Age tip, "Gallium for Aquilo", say that its 20 gallium (or Galinstan) cannot be made on Aquilo. Bring it on the first trip, together with the processing units Aquilo also imports.
  Balance:
    - With Tellurium, Tellurium-assisted semiconductor packaging can also run in the electromagnetic plant, like ordinary packaging.
    - Recycling GaAs no longer rolls quality. No recipe accepts better-quality GaAs.
    - Higher-quality electric ashing kilns now work faster, like other furnaces.
    - The orbital crystal puller weighs 200 kg, like Space Age's foundry and electromagnetic plant: five per rocket instead of twenty.

Version: 0.1.11
Date: 2026-10-05
  Features:
    - Selector combinators require one gallium semiconductor package per output. Preserve all existing
      decider combinators, circuits, crafting time and combinator behavior.
    - Advanced combinators require Gallium crystal growth at the existing blue-science tier. Basic
      constant, arithmetic and decider combinators keep their existing recipes and research.
  Compatibility:
    - Respect the recipe bypass, early or cyclic research placements, and electronics packs that hide
      the standalone package in favor of native components. Update selector recycling refunds.
    - Existing selector factories retain their recipes but need semiconductor packages after upgrading.
      Research Gallium crystal growth if its package recipe is not yet available.

Version: 0.1.10
Date: 2026-09-30
  Compatibility:
    - With Manganese (trikop), manganese-assisted arsenic extraction: 50 purified residue, 50 sulfuric acid, 100 water and 2 manganese plates make 7 arsenic oxide instead of 5. It unlocks after gallium recovery and manganese smelting.

Version: 0.1.9
Date: 2026-09-30
  Compatibility:
    - With Crushing Industry, pulverized coal is made from 1 crushed coal in its crushers instead of from raw coal in an assembler.
    - Pulverized coal then has crushed coal's fuel value, so the ash-recovery boiler makes the same steam per coal as burning crushed coal.
    - Assemblers set to the old pulverizing recipe lose it after the update. Build crushers for that step.

Version: 0.1.8
Date: 2026-09-30
  Bugfixes:
    - Fix the load error "No categories defined" for harene-infused-gallium-crystal-puller when Gallium loads after Rabbasca.
    - Rabbasca no longer makes harene-infused variants of the crystal pullers and the precision slicer. Those variants skipped the seed and orbit rules. Variants already built in a save become the ordinary Gallium machines.

Version: 0.1.7
Date: 2026-09-27
  Graphics:
    - Add a family-style periodic-table thumbnail and release branding.
    - Condense the production-chain gallery image into a readable 4:3 overview.
  Info:
    - Add a player-facing overview, FAQ, compatibility notes and release tooling.
  Features:
    - Add optional GaAs-assisted transceiver fabrication: four ordinary component batches plus two wafers per normal batch's output produce five batches of existing transceivers.
    - Preserve the original transceiver recipe, early radio research, host equipment and recycling. The alternative unlocks after crystal growth and the host radio technology.
    - Add peroxide wafer finishing when actual hydrogen-peroxide production is available: 8 blanks, 5 acid and 5 peroxide make 8 existing wafers.
    - Peroxide finishing takes 12 seconds with sulfuric acid, or 8 seconds with the Phosphorus finishing route; both halve ordinary acid use and fit an ordinary chemical plant.
    - Require the actual peroxide production research and relevant finishing research; preserve earlier recipes and respect integration bypasses.

Version: 0.1.6
Date: 2026-09-27
  Features:
    - Space platforms can dry-finish 32 existing wafer blanks with 2 asteroid carbon into 32 ordinary GaAs wafers in 20 seconds. Unlocks with orbital growth; fixed speed, no productivity or quality gains.
    - Add an alternative scrap-recovery route: 40 scrap, 20 sulfuric acid and 20 water yield 2 GaAs in a chemical plant. Ordinary scrap recycling is unchanged.
    - Space Age electromagnetic plants can finish ordinary wafers and make semiconductor packages with their native productivity.
    - Quantum processors consume two existing GaAs wafers per output processor, preserving their original chemistry and coolant loop.
    - Cryogenic plant construction uses 20 gallium metal, or 20 Galinstan when indium and tin production are reachable.
    - Update the production-chain diagram with the Space Age and platform routes. No new wafer item is introduced.

Version: 0.1.5
Date: 2026-09-27
  Balance:
    - Reduce alumina's trace recovery to a 1% chance of one purified mineral residue per ten-ore batch, 100 times less residue on average.
    - Scale all supported aluminium/zinc routes consistently by ore input, preserving the lower zinc recovery rate and excluding residue from productivity bonuses.
  Features:
    - Advanced processing units and high-voltage power regulators use one thermal-contact portion per existing recipe batch: Galinstan when indium and tin production are reachable, gallium metal otherwise.
    - In the full K2SE pack, one portion supports one advanced processing unit or ten power regulators. Existing ingredients, yields, crafting times and productivity are preserved.
    - Thermal interfaces work independently of Tellurium, with material research prerequisites, cycle protection and individual recipe bypasses.

Version: 0.1.4
Date: 2026-09-27
  Features:
    - Connect BZ Gold's CPU-based replacement electronics chain to GaAs wafers, including Tellurium-assisted CPU fabrication.
    - Existing aluminium and zinc ore processing now yields purified mineral residue as a probabilistic byproduct, including K2 enrichment and Cadmium zinc routes. Main products and previous byproducts are preserved.
    - Successful trace-recovery rolls give 10 residue for existing gallium or arsenic extraction. Normal extraction yields an average of one gallium per 100 aluminium ore or 200 zinc ore; enriched-ore smelting and casting do not recover it a second time.
    - Rename purified mineral ash to purified mineral residue, retaining the existing item and recipes for save compatibility.
    - Expand affected furnace output inventories when needed to fit the extra byproduct.
    - Thermoelectric components use gallium metal as a thermal contact material.
    - With reachable indium and tin production, use Galinstan instead: 7 gallium, 2 indium and 1 tin make 10 portions in a chemical plant.
    - Thermal alloying research follows metal recovery and the host metal unlocks; thermoelectric research requires the selected material.
    - Preserve host solder, heatsinks, batch yields and downstream recipes. Integration bypasses remain available.
  Graphics:
    - Dedicated liquid-metal Galinstan icon.

Version: 0.1.3
Date: 2026-09-27
  Graphics:
    - Purified mineral ash uses a fine pale powder icon instead of tinted stone.
    - Dedicated ash-to-metal recovery research artwork replaces the tinted sulfur crystals.
    - Joint research now shows its product and input material instead of reusing the crystal-growth boule.
    - Phosphoric finishing shows a wafer and phosphoric acid; its existing Phosphorus processing and crystal-growth prerequisites are retained.
  Changes:
    - Extraction keeps its mineral byproduct, using an existing early gravel or sand chain when available and stone otherwise.
    - Residue quantities follow the host's early stone-conversion ratio, including magnesia-assisted extraction.
  Info:
    - Added a production-chain gallery image and a reproducible renderer in the source workspace.

Version: 0.1.2
Date: 2026-09-27
  Graphics:
    - Replace the remaining uranium-235 placeholder for polycrystalline GaAs with dedicated fractured semiconductor crystal artwork.
    - GaAs items and synthesis recipes now share the crystal icon throughout the production chain.

Version: 0.1.1
Date: 2026-09-27
  Graphics:
    - Dedicated seed rods, grown boules, wafer blanks and patterned semiconductor wafers.
    - Counted tier badges and new growth technology icons.
    - Ash, pulverized coal, semiconductor, orbital-cell and detector artwork by Malcolm Riley (CC BY 4.0).
  Changes:
    - The electric ashing kiln upgrades a finished electric furnace and inherits its host-mod construction chain.
    - Electric ashing research follows recovery and the host electric-furnace research; the boiler remains the starter ash source.
    - Use electric motors in kiln construction where available, and the K2 crusher for coal pulverization with K2.
    - Refresh moved kiln unlocks in existing saves without removing placed machines or inventories.

Version: 0.1.0
Date: 2026-09-27
  Features:
    - Initial playable seeded gallium-arsenide semiconductor industry.
    - Recover trace metals from partially recycled ash and competing industrial residue routes.
    - Invest seed modules in crystal pullers, consume working seeds and split boules between wafers and seed stock.
    - Two terrestrial seed tiers and an orbital tier for Space Age and Space Exploration.
    - Electronics, solar and detector integrations with supported material and overhaul mods.
  Graphics:
    - Initial build uses tinted base-game artwork.
