Thanks Ian.
Will appreciate  if xcsoar developers can provide more information on some of 
the changes, especially when removing a useful feature like prefer external 
wind. 

Thanks,

Ramy

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

Max,
I couldnt find more information about "remove setting Prefer external wind" in 
the change log. Can you elaborate?I am always using this setting to get the 302 
wind calculation, as well as to toggle between external wind and manual wind. 
I hope this option is still going to be supported. 
I didnt get a chance to try this myself as I am traveling for some soaring 
events and prefer to continue using the stable version for now. 

Thanks for all the new features,

Ramy
