Version: 1.0.5
Date: 2026-09-20
  Features:
    - Automatically keep quality modules needed by useful crafting recipes, including lower tiers required to make them. No configuration is needed.
    - Quality-only modules become ordinary, effect-free items that cannot be installed in machines or beacons. Unused items, recipes and research stay hidden.
    - Recycling, hidden recipes and quality-module upgrade chains alone do not keep quality modules available.
    - Update affected recipe and research availability in existing saves when useful recipes are added or removed, preserving completed research.

Version: 1.0.4
Date: 2026-09-20
  Changes:
    - Reissued 1.0.3 after withdrawing 2.0.0, restoring the required Quality dependency and the original implementation.
    - Gameplay code is identical to 1.0.3, including the enemy, asteroid and acid exclusions.

Version: 1.0.3
Date: 2026-09-20
  Bugfixes:
    - Fixed spitter, worm and stomper acid stopping or reversing movement instead of applying normal slowing effects.
    - Preserved the gradual recovery of enemy slowing effects, including vehicle speed, friction and speed limits.
  Changes:
    - Expanded regression checks to measure actual movement, overlapping acid, repeated hits, puddle escape, all enemy sizes, asteroid collisions on space platforms and hazard lifetimes.

Version: 1.0.2
Date: 2026-09-20
  Bugfixes:
    - Added an exclusion list so enemies, nests, worms, pentapods, demolishers and all asteroid variants keep normal health, attack damage and range.
    - Enemy acid impacts and lingering puddles retain their original damage.
    - Excluded nest acid clouds, demolisher ash-cloud damage and enemy slowing/disruption effect durations from quality bonuses.
    - Crash-site wrecks, containers and fires, natural Fulgoran lightning attractors and other excluded world objects retain normal stats.
    - Player factories, logistics, defences, characters and equipment retain their quality bonuses, including Spidertron parts shared with excluded entities.

Version: 1.0.1
Date: 2026-09-15
  Changes:
    - New thumbnail.

Version: 1.0.0
Date: 2026-09-12
  Features:
    - Initial release.
    - Removes the quality mechanic: quality badges, selectors, modules, technologies, Factoriopedia entries and tips are all gone.
    - Gives every item and entity the stats of the highest quality tier, so everything is legendary.
    - Generic implementation: all quality prototypes are flattened in data-final-fixes, so mod-added quality tiers and future base-game quality multipliers are covered without a mod update.
