When you 'aptitude upgrade' aptitude will upgrade those packages for
which all the dependencies are resolved and won't break anything. When
you use aptitude interactively and press 'U', you will see every package
that can be upgraded to a higher version. However, it will also alert
you to any 'broken' packages due to dependency problems and gives
suggestions as to how to resolve them.
As a matter of course, you should install apt-listbugs so that you will
be warned of any bugs that could cause you a problem.
