I upgraded the downloadable ("stable") version despite the further testing it might have deserved, but I wanted the potential new recruits from FSweekend to get the newer stuff. You may opt to use it for the festival, since it does correct a couple (minor) bugs, and things are arguably never tested enough anyway lol. Up to you.
The relevant change log is:
- compact radar tags (more realistic radar) -- they expand on mouse over and if linked or selected
- sector file extraction tool integrated to GUI -- generate background drawings from VATSIM/Ivac sector (.sct) files, directly fitting the map (less post-editing required)
- much quicker startup
- radar settings are location-specific
