Changelog

Version: 0.2.0
Date: 2026-10-24
  Balance:
    - Balanced profile: Deep Mine 1.5 MW, Industrial Deep Mine 12 MW.
    - Expensive profile: Deep Mine 3.75 MW, Industrial Deep Mine 30 MW.
    - Default work time 2.0 s per regular ore; speed 0.5 / 5.0.
    - Exactly 60 basic or 6 industrial machines per 15 regular ore/s (no bonuses).
    - Industrial tier uses 20% less energy per ore before modules.
  Modules and quality:
    - Basic Deep Mine: 0 module slots, no beacon effects.
    - Industrial Deep Mine: 2 module slots; speed, consumption and pollution
      effects allowed; productivity effects remain opt-in via existing setting.
    - No quality modules; extraction recipes cannot produce quality resources.
    - Machine quality still affects crafting speed. Quality never adds module slots.
  Compatibility:
    - Preserved all existing machine, item, technology and recipe IDs.
    - Kept planetary conditions and research-productivity rules unchanged.
    - Existing saves with modules installed must be backed up and checked,
      since shrinking a machine's module slots can impact installed modules.
  Notes:
    - Testing build; validate on a backup of an existing 0.1.0 save.

Version: 0.1.0
Date: 2026-10-24
  Features:
    - Initial published release of deep extraction in Factorio 2.1.
    - Two profiles and planet-aware extraction with automatic physical conditions.
    - Research productivity, RU/EN and configurable extraction costs.

  Additional test build adjustment (unpublished 0.2.0):
    - Added independent startup checkboxes for Tier II speed and efficiency modules, enabled by default.
    - Updated productivity module checkbox default to enabled while retaining its identifier for old saves.
    - Kept quality modules disallowed and Mining Productivity research independent.
    - Other module categories from installed mods remain supported except quality.
