Changelog

Version: 0.1.5
Date: 04.01.2026
  Graphics:
    - Standardized all core icons to high-resolution mipmapped assets (256px, 4 levels).
    - Unified technology icons with building and item icons for better visual consistency.
    - Implemented layered recipe icons for Uranium Enrichment and Sand Filtration with correct scaling.
    - Updated item-group and sub-group icons to use high-resolution mipmapped versions.
  Bugfixes:
    - Fixed recipe duplication in Factoriopedia by correctly defining main_product for all recipes.
    - Fixed missing locale translations for item groups and subgroups ("Unknown key").
    - Corrected sand filtration icon overlay positioning for non-square image dimensions.
  Cleanup:
    - Removed obsolete and redundant technology graphics.

Version: 0.1.4
Date: 01.01.2026
  Bugfixes:
    - Fixed changelog formatting to comply with Factorio format specification.

Version: 0.1.3
Date: 29.12.2024
  Features:
    - All radioactive items now cause radiation burns (uranium-235, uranium-238, uranium-ore, fuel cells, nuclear fuel).
    - Damage scales by item type (waste=10, U-235=8, nuclear-fuel=7, fuel-cell=6, depleted-cell=4, U-238=3, ore=1).
  Bugfixes:
    - Fixed Isotope Magnetic Containment technology now unlocks after Nuclear Enrichment (not waste processing).
    - Fixed incorrect icon sizes in technology and item definitions.
    - Fixed entity icon references using wrong image files.

Version: 0.1.2
Date: 29.12.2024
  Bugfixes:
    - Fixed major performance issue causing game hitching/lag every second.
  Optimizations:
    - Player inventory now uses event-based detection (on_player_main_inventory_changed).
    - Containers are registered on build and tracked, no more periodic full surface scans.
    - Container checking spread across ticks (10 containers per tick max).
    - Lights only recreate when state actually changes.
    - Reduced GUI update frequency (30 ticks instead of 15).
    - Clean up of invalid container references on removal.

Version: 0.1.1
Date: 28.12.2024
  Features:
    - Isotope Magnetic Containment unit for radioactive storage.
    - Load-based overload system (capacity 500, critical 70%, danger 90%, explosion 100%).
    - Radioactive waste handling: only containment units can store waste safely.
    - Waste in player inventory or containers causes explosion and damage.
    - Ground waste decays after 5 minutes and creates contamination zone.
    - Dynamic glow effects based on containment load level.
  Balancing:
    - Radioactive load values: waste=5, U-235=3, sand=1.5, U-238=1, ore=0.5.
    - Waste vitrification time: 180s.
    - Sand filtration time: 90s.

Version: 0.1.0
Date: 21.12.2024
  Features:
    - Nuclear Enrichment Plant building (6x6 tiles) with 50% explosion risk per cycle.
    - Uranium enrichment: 50 ore + 10 U-238 = 5 U-235 + 10 waste (120s).
    - Explosions create contamination zones (10 min) with radiation damage.
    - Safety modules (Tier 1-3) reduce explosion risk but decrease speed.
    - Waste processing: radioactive waste = vitrified sand = stone.
  Balancing:
    - Safety Module 1: -10% explosion risk, -15% speed.
    - Safety Module 2: -15% explosion risk, -20% speed.
    - Safety Module 3: -20% explosion risk, -25% speed.
  Info:
    - Technologies: Nuclear Enrichment (requires Kovarex Enrichment Process).
    - Nuclear Waste Processing.
    - Advanced Safety Systems.
  Compatibility:
    - Factorio 2.0, Space Age, BZ Mods.
