+| 2026-11-04 | minor | Corrected the file I/O overview and format-crate row: best-effort `.fig` import and experimental export already exist in `figcraft-format`. No capability or readiness change. |
 | 2026-10-18 | minor | Added `vectordrawable` (L4), the Android Vector Drawable (XML) writer |
 | 2026-10-11 | minor | `collab-net` hosts through one hub for the app's sessions and the standalone server; added the `figcraft-server` app |
