- Linearly interpolate missing stop_times arrival and departure times with tidytransit::interpolate_stop_times() instead of dropping stops (#102)
- Remove duplicate entries across tables with gtfstools::remove_duplicates() (#104)
- Remove unused IDs across tables with gtfstools::remove_unused_ids() (#104)
Bumped gtfstools minimum version dependency to >= 2.0.0 (#103)
