OK, my experiences with 2.0.1:

I had multiple crashes.

I did not get warnings for direction changes (waypoints I think?) until after I was supposed to make the direction change. I am using flite but do not think this should affect the timing of the direction changes.

The gps location stopped updating, but I did not get any indication that the gps stopped updating. IE it did not say it lost connection with the GPS. I am using a holux slim240.

2.x was originally installed over 1.x . I did reboot at some point. I have gone back to 1.x because I needed something reliable.
