Maybe you haven't been around here too long....the iFly has only been in existence for a couple of years, and they're already up to v6 of the software. v4 was released Nov 1 last year, v5 this past spring, and v6 about two weeks ago. They're pretty good about getting significant improvements into the software and out to users on a regular basis.
BTW, v6 was first released for beta testing in mid-August. v6.0.8 indicates that there were several minor version updates during the six-week beta testing period before it was released publicly on October 4.
