SquawkBox can now show aircraft registrations for flights that don't have a flight number. Previously it displayed the ModeS code for such flights but now the program can read RadarBox's navigational database to get the aircraft registration from the ModeS code. This isn't maybe so significant for flights output on port 30003 which tend to have flight numbers but the recorded flight files contain many flights without positional information that lack flight numbers (military etc.).
The displaying of aircraft registrations can be enabled/disabled from Options. Usual download link on website
