I tried the new alpha version on the weekend. It registered a plausible 
wind vector within 30 seconds on aerotow. It was a wave day >70km/h wind.

But it crashed less than a minute later (Dell 5, ioio card), so  I 
started the stable version that worked as expected for the next 4 hours.

I rely on the wind calculations for ridge and wave flights. I have 
scanned the change log files for entries related to wind, but some of 
the entries are very terse. I also looked at the source file patches but 
I am not 100% sure what algorithm is inside each version. Is there a 
discussion on the developers list or other source of info on this?

(Off topic, I am curious what wind algorithms are inside the Top Hat 
fork of XCSoar).

Does the alpha version log a crash dump file, if so would you like me to 
upload it in a bug report?

Thanks

Ian
