+## [2.26.2] - 2026-03-13
+
+### Fixed
+- **Docker startup crash** — `.dockerignore` excluded the entire `data/` directory, which is now a Python package (`data.oui`, `data.patterns`, `data.satellites`). Caused `ModuleNotFoundError: No module named 'data.oui'` on container startup. Fixed by only excluding non-code files from `data/`.
