Keith and I just released version 0.8 of AltOS, the open source firmware and software system associated with our TeleMetrum hobby rocket avionics system.

The AltosUI ground station user interface is significantly improved, with lots of new features including a much cleaner view of what's happening during different stages of the flight experience, a post-flight data plotting interface with pan and zoom, and a very cool live view of where the rocket is overlayed on data from Google Maps! All existing TeleMetrum owners are encouraged to download, install, and begin using this new version immediately.
