Changelog

Version: 2.13.0
Date: 2026-07-21
  Features:
    - The mining/pickup quality upgrade now also applies to construction bots. Bots harvesting trees/rocks (or, in "Everything" mode, deconstructing structures) get the same quality roll as hand-mining, via the on_robot_mined_entity event.

Version: 2.12.2
Date: 2026-07-21
  Changes:
    - Added a warning to the Quality Cap setting description: Force modes break vanilla hand-crafting (the hand-craft menu only accepts normal-quality ingredients), so craft in machines instead. This is a Factorio limitation, not a mod bug.
  Bugfixes:
    - Force mode produces the forced tier on machines again. Factorio 2.1 split the quality roll into two per-tier fields: "next_probability" (the initial upgrade) and a new "chain_probability" (each cascade step, defaulting to just 10%). The mod only forced next_probability, so machines got a guaranteed first step to uncommon and then crawled upward at 10% — legendary almost never. Hand-crafting was unaffected because it assigns the tier directly, bypassing the quality engine, which is why hand-crafting kept working while miners, smelters, and assemblers did not. Both fields are now forced to 100% for every tier below the cap.

Version: 2.12.1
Date: 2026-07-21
  Bugfixes:
    - Machine quality bonus was 10x too high: the default Quality Bonus of 15% was being applied as 150%, so machines (miners especially) could never produce normal-quality items. Machines now use the true percentage and match the hand-craft / hand-mining math.
  Changes:
    - Removed the "Quality research auto-unlocked!" chat message that printed on every load. Research is still auto-unlocked; it just no longer notifies you.

Version: 2.12.0
Date: 2026-07-21
  Features:
    - Consolidated the mining/pickup upgrade into a single "Pick-Up / Mining Quality Upgrade" dropdown: Off / World resources only / Everything. Defaults to World resources only (upgrades trees, rocks, ore, fish, plants but not structures). "Off" disables all pickup/mining upgrading; "Everything" also upgrades picked-up structures.
  Changes:
    - Replaces the separate "Mining Quality Upgrade" and "Pick-Up (Glove) Quality Upgrade" toggles from 2.11.0.

Version: 2.11.0
Date: 2026-07-21
  Bugfixes:
    - Picking up a placed structure (belt, machine, inserter) no longer re-rolls its quality. Previously you could upgrade structures for free by picking them up and re-placing them (belt-drag + rotate did this en masse), and it could silently change the tier of machines built at a different quality.
  Features:
    - New "Pick-Up (Glove) Quality Upgrade" setting to control the above. OFF by default; turn it on if you actually want picked-up structures upgraded.
  Changes:
    - Updated for Factorio 2.1.
    - Mining upgrade now applies only to natural world resources (trees, rocks, ore, fish, grown plants), keeping it separate from structure pickup.

Version: 2.10.0
Date: 2026-05-27
  Features:
    - Quality Cap / Force setting: cap the quality chain at a tier or force every produced item to an exact tier.
    - Hand-craft quality upgrade hook (runtime toggle).
    - Mining quality upgrade hook for trees, rocks, hand-mined ore and fish (runtime toggle).
  Changes:
    - data-final-fixes now duck-types every prototype for crafting_speed / mining_speed instead of using a type allowlist.
