Hi Rafael,

The main issue I see with automatically moving to 4.0, is that if a year
from now we decide we want to drop a bitcode feature, we can't really do
it unless we bump the major version again to 5.0.  If we continue on
with 3.x, then we still have the flexibility to drop bitcode features
when we decide it's necessary.
