Trying to keep up with the plan for the 3.5 release, here's the update 
to advance from 3.5beta to 3.5gamma.  An option to advance to 3.6alpha 
is provided again, since there were no updates in between.

Because there are no tweaks to the image itself (other than the 
updates) in this short 3.5 release, we will probably forego building a 
3.5gammaOne image.
