Changelog

Version: 2.1.1
Date: 2026-08-13
  Changes:
    - Added planet and production facility restrictions for laser turret MK upgrades:
        MK1: Assembler 3 on Vulcanus
        MK2: Electromagnetic plant on Fulgora
        MK3: Cryogenic plant on Aquilo
        MK4: Cryogenic plant on a space platform
    - Adjusted item stack sizes: MK1=40, MK2=30, MK3=20, MK4=10.
    - Adjusted crafting times: MK1=20s, MK2=30s, MK3=40s, MK4=50s.
    - Optimized energy parameters for MK1–MK4:
        Energy per shot: 700kJ / 600kJ / 500kJ / 400kJ
        Buffer capacity: 901kJ / 1001kJ / 1101kJ / 1201kJ
        Input flow limit: 2200kW / 2000kW / 1800kW / 1600kW
        Drain: 22kW / 20kW / 18kW / 16kW
    - Removed specific numeric values from item and technology descriptions.
    - Added sci-fi flavored descriptions combining planet characteristics and materials.
    - Fixed base laser turret subgroup assignment to keep it with MK upgrades.
    - Created missing recipe categories (electromagnetics, cryogenics) automatically.
    - Added custom English and Chinese locale files.

Version: 2.1.0
Date: 2026-07-12
  Changes:
    - Fixed compatibility with Factorio 2.1: Changed recipe prototype field `category` to `categories` for MK3 and MK4 upgraded laser turret recipes, resolving a breaking API change that merged `category` and `additional_categories` into a single `categories` table.
    - MK1 and MK2 recipes now also explicitly specify `categories = {"crafting"}` for consistency and future safety.

Version: 1.1.1
Date: 2025-06-13
  Changes:
    - Added item weights to upgraded laser turrets based on rocket capacity reduction:
      MK1 50kg, MK2 66.667kg, MK3 100kg, MK4 200kg.
    - Weight progression follows the rule that each tier reduces rocket payload by 5
      (from the vanilla 25 payload, i.e., 40kg per turret).

Version: 1.1.0
Date: 2025-06-06
  Changes:
    - Increased damage modifiers to 4/8/12/20 per tier.
    - Overhauled energy system: buffer capacity, input flow limit, drain, and attack consumption now scale progressively, greatly improving sustained fire capability.
    - Updated recipes to use advanced Space Age materials: tungsten plates, tungsten carbide, superconductors, supercapacitors, carbon fiber, ammonia, quantum processors, promethium asteroid chunks, and cold fluoroketone.
    - MK3 and MK4 now require a cryogenic plant for final assembly.
    - Technology packs rebalanced: all tiers include space science packs; MK3 adds agricultural and cryogenic packs; MK4 adds promethium science pack.
    - Replaced manual animation building with recursive mask tinting (inherited from Rocket Turret upgrade logic), ensuring correct coloring across all turret states.
    - Unified custom icons for items, entities, and technologies.
    - Updated English and Chinese locale with full descriptions.

Version: 1.0.0
Date: 2025-05-01
  Changes:
    - Initial release. Adds MK1–MK4 laser turret upgrades with increased range, damage, fire rate, and reduced energy consumption.
