This week we were joined by Doug Weibel and Jason Short, the team leaders of the ArduPilot and ArduPilot Mega code project. They're the ones working hard on getting the APM Beta ready for release at the end of the month (alpha is already out, of course), and talked about the design and feature decisions they made with APM, as well as the roadmap for 1.0 (in September) and beyond.
