May be actual users can fill in the gap:

 

I see the following changes:

 

New XML variables in web.config:

UseDNNRoleASFileNamePrefix="true"

UseDNNDefaultWidth="false"

 

- Email link (mailto:) bug (when you have multiple email links, they are altered to become the same one)

- image root is now pointing to /portals/0 instead of /portals/0/Member

- File security based on role (Adding 'Member_' prefix)
