Changelog

Version: 0.5.0
Date: 2026-10-25
  Graphics:
    - Refined the deep-well artwork to fit the 5x5 footprint and its four fluid connections.
    - Replaced the former opaque deep-well shadow with a transparent, softer contour shadow.
    - Corrected deep-well wreck size and removed inherited corpse ground/decay overlays causing an oversized dark patch.
    - Rebuilt the deep-well control-panel LEDs with small, aligned indicators: steady green status and slow amber activity pulse.
    - Slowed the eight-frame deep-well LED animation to approximately 3.33 seconds per cycle at 60 UPS.
    - Reworked precipitation-tank destroyed sprites with a damaged maintenance bridge, broken central structure, sludge and debris.
  Info:
    - The custom building graphics are provisional placeholder artwork. Their quality does not match the professional visual standard of Wube Software's original Factorio graphics.
    - Contributions or replacement graphics from experienced artists are very welcome.
    - Existing-save notice remains important: natural water sources become raw water and dependent production may need adjustment.

Version: 0.4.0
Date: 2026-10-24
  Changes:
    - Ported Water Processing Fork from Factorio 2.0.77 to the Factorio 2.1 API and metadata format.
    - Updated the base and optional Space Age dependency floor to Factorio 2.1.20.
    - Migrated 13 recipe category definitions and Krastorio 2 recipe patches from `category` to the Factorio 2.1 `categories` array.
    - Migrated the three probabilistic used-filter outputs from `probability` to `independent_probability`.
    - Preserved the existing fluid-box layout, natural-water to raw-water conversion, Space Age surface restrictions and Space Exploration deep-well runtime checks after API review.
  Compatibility:
    - Verified the release build on Factorio 2.1.23 Stable with Krastorio 2 2.1.4 and Space Exploration 0.7.63 in the combined K2SE stack.
    - Confirmed the final Water Processing compatibility contract with no reported errors in the tested K2SE modpack.
    - No additional Water Processing code changes were required between the original 2.1.20 port target and Factorio 2.1.23 Stable.
    - Replaced the precipitation-tank art package in the working test build with the approved simplified basin and 24-frame clarifier animation.
    - Added a first dedicated precipitation-tank remnant asset and linked it to a mod-owned corpse prototype for destruction tests.
  Info:
    - Existing-save warning remains unchanged: natural water tile sources can become raw water and existing offshore-pump supply chains may need rebuilding.
