Got it from Garmin Express too, right after it was announced!
Just a remark - looks like they finally dropped the 5.0 GPS version introduced in the 12.77 beta, I upgraded from the previous stable 12.10 and I am still on 4.60
They often push out GPS updates separate to core software updates. I expect in the next week we'll all get pushed 5.00 if we haven't already manually installed it.
