The history of the 0.8 cap was the fact that 0.8beta1 (or something 
equiv) was uploaded near a freeze point. <0.8 didn't stop 0.8beta1 from 
being used (go version numbers).

Also in 0.8 a piece was spun out as a separate library (I don't remember 
exactly which), which causes some build fails. Because it was around a 
freeze the cap was the right approach.

However, projects really should be getting themselves on 0.8 in the 
Havana time frame. AFAIK it's really minor changes to work, so should be 
a simple review to bump it up.
