Changelog

Version: 0.1.8
Date: 2026-09-20
  Changes:
    - Explosives technology now requires Electrolysis, explicitly locking the vanilla explosives branch behind GZ electrochemistry.
    - The existing Explosives unlock effects remain unchanged; only the research prerequisite is added.

Version: 0.1.7
Date: 2026-09-20
  Features:
    - Water Electrolysis now produces 100 Hydrogen Gas + 50 Oxygen Gas from 100 Water.
    - Added Oxygen Gas as the useful coproduct of electrolysis.
    - Added Advanced Glassmaking when the shared GZ sand/glass chain is present.
    - Advanced Glassmaking runs in the Foundry: 20 Sand + 10 Oxygen -> 10 Glass in 4 seconds.
    - A standard Space Age Foundry (crafting speed 4) therefore produces a nominal 10 Glass per second before productivity bonuses.
    - Advanced Glassmaking is unlocked by Electrolysis alongside the rest of the hydrogen/oxygen branch.

Version: 0.1.6
Date: 2026-09-20
  Features:
    - Added Electrolysis technology after Electric Energy Distribution 2 for 200 Automation, Logistic, and Chemical science packs.
    - Electrolysis now gates water electrolysis, Iron Catalyst, Hydrogen Fuel Cells, Hydrogen Rocket Fuel, and the Hydrogen Reactor.
    - Added an alternate Rocket Fuel recipe using 10 Solid Fuel + 100 Hydrogen Gas.
    - Moved reusable ownership of the compact 2x2 Hydrogen Reactor prototype into GZ-Chemistry.
    - Copies the compact Terra Hydrogen Reactor artwork directly into GZ-Chemistry so the reactor is self-contained and reusable without Terra.
    - Added a craftable Hydrogen Reactor recipe: 20 Steel Plate + 20 Advanced Circuits + 20 Copper Plate + 5 Iron Catalysts.
  Graphics:
    - Uses the approved bottle graphic for Hydrogen Gas.
    - Added the transparent electrolysis reactor artwork as the Electrolysis technology icon.

Version: 0.1.5
Date: 2026-09-20
  Features:
    - Added Hydrogen Gas with the generated bottle icon and a Chemical Plant water-electrolysis recipe.
    - Added Iron Catalyst: 2 Iron Plate + 1 Carbon Fiber + 10 Ammonia.
    - Added Empty Hydrogen Fuel Cell and a hydrogen filling recipe producing the existing shared Hydrogen Fuel Cell item.
    - Empty fuel-cell construction uses 1 GZ Chitin Membrane when available; otherwise it falls back to 2 Carbon Fiber.
    - Hydrogen Fuel Cells are single-use and never return an empty cell after burning.
  Compatibility:
    - Reuses GZ-Terra's existing `hydrogen-fuel` / `gz-hydrogen-fuel-cell` prototype contract so the new chemistry chain feeds the existing hydrogen reactor integration.

Version: 0.1.4
Date: 2026-09-20
  Changes:
    - Explosives recipes now require 10 Nitric Acid per craft.
    - The nitric-acid requirement is applied in final fixes so downstream explosive weapons inherit the chemistry cost through Explosives.

Version: 0.1.3
Date: 2026-09-20
  Changes:
    - Ammunition recipes now require 1 Saltpeter.
    - Grenade recipes now require 2 Saltpeter.
    - Recipe patching runs in final fixes so compatible ammunition/grenades from other mods are included automatically.

Version: 0.1.2
Date: 2026-09-19
  Features:
    - Added a resource autoplace control for saltpeter with frequency, size, and richness support.
    - Saltpeter geography remains unassigned so terrain/campaign mods can own placement.

Version: 0.1.1
Date: 2026-09-18
  Features:
    - Added the base Nitric Acid chemistry recipe.
    - 5 Saltpeter + 20 Sulfuric Acid -> 20 Nitric Acid + 5 Sulfate Waste in 4 seconds.
  Notes:
    - Sulfate Waste remains a solid chemistry byproduct for later fertilizer/mineral reclamation.
    - Chitin-specific macerates remain owned by GZ-Chitin.

Version: 0.1.0
Date: 2026-09-18
  Features:
    - Initial shared chemistry prototype layer.
    - Added Saltpeter item and resource prototype.
    - Added Sulfate Waste item.
    - Added Nitric Acid fluid.
  Notes:
    - Saltpeter has no built-in autoplace; terrain/campaign mods own placement.
    - Downstream macerates are intentionally not owned by GZ-Chemistry.
