Historical retained release note. The original note is evidence of a release record, not a verified deployment date.

Adds high-farm evidence for native 4K and 7K and farm-only filtering with key-mode checks. Sparse pools keep the star-rating boundary, prefer the best-fitting candidates, and can expand length and configured ranked-map age. They retain pass-count, quality, status, key-mode, and download gates.

An empty style preserves the previous pool under that historical implementation; later v6.6.14 style exhaustion fallback broadens native choices with notices.

This is an editorial summary of the original patch note. See Mania Farm, selection rules, and release history.
