diff is your friend here. Both profiles have the same grandparent so 
there are just a few pairs of files to run diff on (omitting the 
headers and comments). Unfortunately the right hand file name in the 
diff output is marked with a ">" which will upset your mailer's quote 
tracking :-(   :

Summary: You get a few extra USE flags by default (which you can 
explicitly override in make.conf), cdrkit is the default cdrtools 
package, and the .bashrc for the shell that portage uses has had some 
syntax corrected to a better form.

Chances are you are already using acpi, pdf, svg and tiff USE flags so 
these will cause no change if you upgrade your profile. The few 
packages in the tree that USE kerberos may need to be recompiled if 
this flag changes for you
