Direct answer

Firmware releases should version every config blob, migrate forward with safe defaults for new fields, and avoid silent downgrades during rollback. A companion app that edits sensor sampling intervals should read the schema version first, then hide unsupported options. Test migrations from several shipped releases, not only the previous build.
