====== v6.6.19: Expanded Mania catalogs and refreshed Farm ======

**Deployment record:** validated and queued for automatic empty-safe deployment on September 30, 2026. At this article's publication, v6.6.18 was active. Check the current-version notice on [[updates:start|the release index]] before treating these changes as live.

===== What changes =====
The completed Mania collection and chart analysis refresh the native 4K and 7K catalogs, structural styles, and Farm evidence. The rooms keep their separate key modes and existing difficulty, playable-length, pass-count, and repeat policies. Vetted osu!standard converts remain Variety-only; the figures below count native Mania charts.

Across **all supported star ratings and playable lengths (45–600 seconds)**, with Ranked/Approved status and at least 1,000 passes, the number of native charts that could potentially be selected rises from **20,071 to 20,641** (+570, about 2.8%). These are catalog-wide possibilities, not the number available in any one lobby range or moment.

^ Native Mania pool ^ Previous catalog ^ v6.6.19 catalog ^ Change ^
| 4K potentially selectable | 16,429 | 16,987 | +558 |
| 7K potentially selectable | 3,642 | 3,654 | +12 |
| Both rooms combined | 20,071 | 20,641 | +570 |

The refreshed catalogs have named structural style evidence for **16,675 4K** and **3,593 7K** charts; other eligible charts can still appear in Variety. Farm scores cover more charts, but a score is not the same as a strict ''.farm'' qualification. The recalibrated strict Farm pool has **4,406 4K** and **1,028 7K** qualifying charts under the same broad hard filters, or **5,434 total**. That is smaller than the previous **5,835** strict qualifiers because the new score cutoffs are more selective. For eligible 45–180-second charts, the cutoffs target roughly one quarter in each key mode.

''.farm'' still starts with the highest-scoring eligible fresh charts; if a style is exhausted, the existing [[wiki:style_fallback|fallback]] can broaden selection without bypassing hard filters. The research database's player-score and collection history is not needed in the compact lobby catalogs. See [[wiki:mania_farm|how Mania Farm works]] and [[wiki:map_selection|selection rules]].
