v2.41.0 — Unity 6.6 modernization and maintenance audit
Companion server: v2.36.0. Older servers keep working: features are negotiated through capabilities.
🧭 Unity 6.6 modernization
- Unity 6.6 support, fair per-agent queues, protected tickets and targeted Undo.
- Native multiplayer controls (MPPM, ParrelSync), persistent paginated test results and detailed editor monitoring.
- The MCP status shows in the toolbar automatically, with one shared MCP menu from the toolbar, Dashboard, Action History and the Window/Tools menus.
- UMA moved to an optional assembly and works with UMA 3, including vendored installs (#25, #27).
🔒 Security and reliability
- Category toggles now block the routes they name: prefs, project settings, prefab assets and the memory profiler.
- Bridge diagnostics, history and settings start on the main thread; ticket numbers are not reused after a domain reload; one large result no longer evicts every pending one.
🛠 Command fixes
- Prefab variant apply, revert and compare actually change the variant (they did nothing before), honour their filters and record revert/unpack in Undo.
- Create, instantiate and reparent fail on an unknown parent instead of using the scene root.
- Object references are type-checked; Transform removal and overwriting another scene or prefab are refused unless asked.
- NavMesh agent settings, ScriptableObject flag enums, UI fonts on 2021.3, material
properties, typed keyframes and 1D blend-tree thresholds now work as documented.
⚡ Editor performance
- Scene statistics count triangles without copying index buffers; variant lookup no longer loads every prefab; captures import one file instead of refreshing the AssetDatabase; type lookups are cached; find-by-type is capped.
- README GIFs moved to
Documentation~, so Unity no longer imports about 11 MB of images.
