Just a quickie to reasure some folks; It took me two attempts to get my Rossetta working with the upgrade. No wifi popped up after a couple of hours first time round, so simply powered down, reformatted the SD, reloaded the files and went again. Worked fine this time. Remember that if you want the Mode S 3D, you specifically have to enable it, same for bearingless contacts. Now been running for about 24 hours with no hint of falling over, which on previous release was not possible. Thanks to the team for the improvements.
