Not really a bug per se, but the default build timeout of 10 is too low to get some of my more advanced projects compiled. I remember I also had to change it in the beta, I've just set it to the maximum of 300 now.
If you really want to impose a build timeout then I guess a default of 60 would be more appropriate.
But personally I would prefer to see an option to not have a build timeout threshold at all (like it was in the 2.2.6 sdk) (Proposal: allow 0 and implement it as no timeout)
