Doesn't seem like much info on the APU anomaly:

Analysis shows that one temperature measurement exceeded a pre-defined limit and that the flight software correctly triggered a shut down

Sounds like the fix is changing the start up procedure such that it doesn't reach the temperature limit. It would be nice to know why it went outside what they deemed safe but I guess it is rocket science.

Yes, not really the complete picture of what happened.

Would have there been actual damage to the system or even destruction if the software did not shut down? Or was the temperature threshold set too conservative? Did the thermal simulations not match the observed temperatures and if so why?

What's the solution to this problem now for the next flight?
