If not, it's probably because the have not been updated to match the aptitude 
in Lenny (which is fine, since Lenny isn't out yet).  From Lenny forward the 
old "upgrade" is now "safe-upgrade" and the old "dist-upgrade" is 
now "full-upgrade".

I suppose these names better fit what the different solvers[1] do.  The full 
upgrade may not move you to a new "dist", but it will remove packages in 
order to upgrade more packages.  The safe upgrade will avoid removing 
packages (most likely cause of breakage) even if that means not upgrading a 
package.  That's pretty much always been their behavior, even under their old 
names.

[1] Same solver, just different weights for different actions.
