Version: 0.2.2
Date: 2026-03-09
  Features:
    - Added a complete 5-stage thermodynamic metallurgy chain (Dust -> Pellet/Sponge -> Fluid/Gas Intermediate -> Ingot -> Plate) for Magnesium, Aluminum, Nickel, Lead, Zinc, Gold, Silver, Rare-earth, and Titanium.
    - Introduced realistic chemical intermediate fluids with dynamic sprite tinting, including Molten Magnesium Chloride Salt, Alumina-Cryolite Melt, Toxic Nickel Carbonyl Gas, Pressurized Zinc Vapor, and Precious Metal Leach Solutions.
    - Implemented cross-metal technology dependencies: Titanium smelting now strictly requires the Kroll process, consuming Magnesium ingots as a reducing agent.
    - Added Hydrofluoric Acid processing from Fluorite dust.
    - Added full English localization (config.cfg) for all new chemical processing recipes, fluids, and intermediate products to enhance the realistic industrial immersion.
  Changes:
    - Temporarily reverted the supply area and wire distance of electric poles and substations to vanilla values for better gameplay stability while the thermodynamic power grid is being refined.
    - Optimized mod file size and memory usage by implementing palette swapping (sprite tinting) for fluids, ingots, and plates based on vanilla and Space Age assets instead of using duplicate image files.
  Bugfixes:
    - Fixed a critical load error caused by a missing string definition during the generation of the Titanium Sponge item.
    - Fixed an invalid file path concatenation error caused by an empty string in the pure dusts iteration array.
    - Added missing "main_product" definitions to all multi-product recipes (e.g., wet separation, casting with steam byproducts) to prevent UI icon rendering errors.

Version: 0.2.1
Date: 2026-03-05
  Features:
    - Life Support System Overhaul: Implemented a "Magnitude Gating" energy-drain mechanic. Environmental hazards now dynamically drain energy from "Host" equipment (e.g., Mask, APF, CLS) based on pollution levels and planetary conditions.
    - Tiered Protection & Override: Added a hierarchy system to life support. The script now automatically selects the highest-tier equipment (CLS > APF > Mask) in the player's grid to handle protection, preventing multi-tier energy waste and cross-system conflicts.
    - New Equipment Modules: Introduced the 1x1 Filter Box Equipment for early-game protection and the Ammonia Scrubber Interface specifically for Aquilo's atmospheric hazards.
    - Planetary Environmental Rules: Standardized survival requirements across all planets. Vulcanus, Fulgora, and Aquilo now strictly require CLS-tier interfaces or universal Gas Canister Docks to provide protection.
  Bugfixes:
    - Fixed Copper Mining Crash: Resolved a "non-recoverable error" caused by an empty item name string in the mining script. Standardized the resource collection logic to correctly process copper-ore into crushed-copper.
    - Fixed Burner Idle Issue: Implemented a forced-drain logic to ensure burner-based interfaces (generators) continue to consume filters even when high-tier power sources (like Nuclear Reactors) are present in the equipment grid.
    - Refined Flying Text: Adjusted the position of mining feedback text to prevent overlapping with vanilla item pickup indicators.
    - Equipment Prototype Fixes: Corrected several prototype definition errors, including missing "shape type" properties and invalid energy source configurations for battery and generator equipment.

Version: 0.2.0
Date: 2026-03-03
  Features:
    - Added 10 new advanced minerals & precipitates.
    - Implemented advanced stone processing.
    - Overhauled Sulfate Leachate extraction.
  Bugfixes:
    - Fixed 2.0 Probability Syntax Crash: Replaced legacy amount tags with the strictly required amount_min and amount_max in all probability-based recipe outputs.
    - Fixed Recipe Interceptor: Added a strict blacklist to the global script, preventing it from hijacking manual crafting recipes (e.g., pure stone crushing) and building entities.
    - Streamlined Waste Logistics: Merged redundant acidic byproduct fluids into a unified Acidic Waste loop to reduce late-game piping clutter.

Version: 0.1.9
Date: 2026-03-02
  Bugfixes:
    - Tech Tree Progression: Reorganized the technology tree prerequisites for a smoother transition from Automation to Logistic Science.
    - Resource Identity: Resolved an issue where crushed rocks and raw ores were not properly recognized by the early-game Crushers.
    - Science Packs: Adjusted the ingredients for the Logistic Science Pack to better fit the hardcore Wasteland theme.
    - Machine Categories: Corrected crafting categories and fluid box connections for several mid-tier furnaces (preparations for future updates).

Version: 0.1.8
Date: 2026-03-01
  Features:
    - Introduced the Hardcore Belt Power mechanic: All transport belts, underground belts, and splitters now require an active Drive Node to function.
    - Added 5 tiers of Belt Drive Nodes (Steam, Normal, Fast, Express, and Turbo), utilizing mechanical steam, electricity, or high-voltage fluids.
    - Added "Steam Transport Belt", a slow, early-game belt variant powered by early boiler steam.
    - Implemented a "Recipe Cloning" system for the Foundry: mass-production recipes (Casting Belts, Pipes, Drills) now exclusively exist in the Foundry and require High-Voltage Fluid, keeping early-game hand-crafting clean.
    - Added a new "Primary Steel Processing" technology to bridge the gap between Automation and advanced steel processing, unlocking Primary Carbon Steel.
  Changes:
    - Overhauled Crash Site loot: Both the starting containers and mined shipwreck debris now yield authentic early-wasteland materials (Pig Iron Plates, Cast Iron Gears) instead of pure vanilla metals.
    - Overhauled Early-Game Recipes: Automation/Logistic science packs, Inserters, Turrets, Firearms, Radars, and basic base-building items now strictly utilize Pig Iron, Blister Copper, and Carbon Steel.
    - Adjusted Research Triggers: Early technologies (like Steam Power and Electronics) now require crafting Pig Iron and Blister Copper instead of vanilla plates.
    - Buffed Mineralized Geode drops: All rock types across the map now have a guaranteed, highly consistent chance to drop Mineralized Geodes when mined.
  Bugfixes:
    - Fixed an issue where modifying belt recipes to `metallurgy` polluted the early game by forcing lubricant/fluid requirements into hand-crafting.
    - Fixed a Factorio 2.0 API crash caused by legacy `global` variables (migrated to the new `storage` system).
    - Fixed a recipe generation crash by updating legacy `result` definitions to the strict Factorio 2.0 `results` array format.
    - Fixed an entity definition crash by utilizing `storage-tank` prototypes for fluid-consuming drive nodes, bypassing the engine's strict `electric-energy-interface` limitations.
  Optimizations:
    - Designed a highly UPS-friendly "Node-Centric" scanning algorithm for the Belt Power mechanic. Belts immediately paralyze upon placement, and the script only scans entities within the active radius of placed Drive Nodes every 2 seconds, eliminating full-map surface scans.

Version: 0.1.7
Date: 2026-02-28
  Features:
    - New Mining Mechanics: Implemented a dedicated mining handler in scripts/mining_mechanic.lua. Manual mining now yields iron-ore, which must be crushed into usable ore.
    - Coal Chemistry Chain: Introduced a comprehensive coal processing overhaul, including Raw/Clean Coal Gas, Coal Tar, Washed Coal, Coal Pitch, and Activated Carbon.
    - High-Resolution Assets: Added numerous 128x128 high-definition PNG icons for items such as tungstic-acid-precipitate and calcite-powder to standardize visual quality.
  Changes:
    - Icon Standardization: Updated all item definitions to use the Factorio 2.0 icons dictionary format with an icon_size of 128.
    - Recipe Refactoring: Reconstructed all ore-processing and chemical recipes using the modular table.insert format for easier maintenance and compatibility.
    - Asset Cleanup: Removed the silicon-wafer item and deprecated legacy coal-chemistry overwrite scripts.
    - Resource Scaling: Increased the visual scale of surface iron and copper deposits to 0.8 to provide a more "bulky" wasteland aesthetic.
  Bugfixes:
    - Mining Event Isolation: Fixed a critical crash by strictly isolating on_player_mined_entity from robot or biter destruction triggers.
    - Prototype Errors: Fixed "Duplicate fluid ingredients" errors and corrected mismatched icon mipmap sizes.
    - Fluid Connections: Resolved "Position outside bounding box" errors for new 4x4 heavy mining drills and beacons.
  Translations:
    - Updated English and localizations for all new coal-chemistry products, mechanical components, and mining results.

    - Added 4 planetary Environmental Science Packs: Vulcanus, Gleba, Fulgora, and Aquilo.
    - Added cinematic nuclear blast effect: 45-radius lava lake with 2-minute dynamic cooling animation.
  Changes:
    - Rebalanced furnace tiers: Stone (Combustion), Steel/Alloy/Tungsten (Heat-based), Electric/Foundry (EM Fluid + DC Power).
    - Redesigned Electric Furnace and Foundry pipe connections: Moved to East/West sides with input-output flow for seamless cascading.
    - Overhauled Foundry recipe logic: Automatically injects High-Voltage EM Fluid requirements into all metallurgy/pressing recipes.
  Bugfixes:
    - Fixed critical crash on initialization by migrating from 'global' to Factorio 2.0 'storage' dictionary.
    - Fixed 'Duplicate fluid ingredients' error during recipe setup via new Safe-Injector logic.
    - Fixed 'Unknown tile name' crashes during nuclear detonations on specific planets.
    - Fixed visual artifacts where nuclear ground failed to merge with lava lakes.
  Translations:
    - Added English localization for all new science packs, furnaces, and EM fluids.

Version: 0.1.5
Date: 2026-02-20
  Features:
    - Removed player/robot mining destroy events, tweaked pollution and waste mechanics, updated data requires, and added a centrifuge entity update.
    - control.lua: stopped listening for on_player_mined_entity and on_robot_mined_entity (only on_entity_died remains).
    - data-updates.lua: reordered/restored requires and added updates.entities-updates.centrifuge.
    - scripts/tree_reaction.lua: changed pollution constants (tree absorption and release values) to alter tree death/pollution behavior.
    - scripts/waste_mechanic.lua: adjusted check interval, pollution per emission, and spread radius to change waste outfall behavior.
    - updates/entities-updates/centrifuge.lua: new file configuring centrifuge fluid_boxes and compatibility fixes.
  Changes:
    - These changes address gameplay balance and compatibility with recent engine/entity API adjustments.
