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 gun 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 future safety.

Version: 1.1.3
Date: 2025-06-13
  Changes:
    - Added item weights for upgraded gun turrets: MK1 25kg, MK2 33.333kg, MK3 50kg, MK4 100kg.
    - These weights affect rocket transport capacity, making higher-tier turrets progressively heavier.

Version: 1.1.2
Date: 2025-06-13
  Changes:
    - Mod display name changed to "更好的机枪炮塔" (Better Gun Turrets).
    - Dependencies updated to require Space Age and Quality DLC (no longer optional).
    - Internal names, recipes, technologies, and all other data remain unchanged, ensuring full backward compatibility with existing saves.

Version: 1.1.1
Date: 2025-06-06
  Changes:
    - Added missing "modifier-description" locale entries for upgraded gun turrets, fixing "Unknown key" errors when dynamic technology patch applies turret-attack bonuses.

Version: 1.1.0
Date: 2025-06-06
  Changes:
    - Overhauled stats to match the Rocket Turret upgrade line: health, damage modifier, ammo slots, and automatic ammo count now scale identically.
    - Fire rate reworked: cooldown now decreases by 1 tick per tier (MK1: 5, MK2: 4, MK3: 3, MK4: 2).
    - Range now increases by 4 per tier (22/26/30/34).
    - Recipes updated:
        MK1: Standard gun turret + 20 tungsten plates + 20 tungsten carbide.
        MK2: MK1 + 20 superconductors + 20 supercapacitors.
        MK3: MK2 + 20 carbon fiber + 500 ammonia (fluid). Must be produced in a cryogenic plant.
        MK4: MK3 + 20 quantum processors + 20 promethium asteroid chunks + 200 fluoroketone (cold) (fluid). Must be produced in a cryogenic plant.
    - Technology packs rebalanced:
        MK1: Automation, Logistic, Military, Chemical, Metallurgic, Space.
        MK2: Automation, Logistic, Military, Chemical, Metallurgic, Electromagnetic, Space.
        MK3: Automation, Logistic, Military, Chemical, Metallurgic, Agricultural, Cryogenic, Space.
        MK4: Automation, Logistic, Military, Chemical, Metallurgic, Agricultural, Cryogenic, Space, Promethium.
    - Added a dynamic technology patch: all physical-projectile-damage technologies now automatically apply their turret-attack bonus to upgraded gun turrets (MK1–MK4), ensuring full compatibility with vanilla damage research.
    - Fully reworked visuals:
        Adopted the same recursive tinting logic used by the Rocket Turret upgrade mod, guaranteeing correct mask coloring on all turret states (folded, preparing, attacking, etc.).
        Custom icons for items, entities, and technologies have been polished and unified.
    - Entity, item, and technology graphics now exclusively use the custom high-quality icons.
    - Locale files updated with detailed descriptions for both English and Chinese.
    - Mod thumbnail and description updated.
    - Other minor fixes and performance improvements.
