On my system, when I run

apt-get dist-upgrade

and say "yes" to the list of packages, the following things happen:

* apt-get downloads all the packages, but does not install them yet.
* apt-listchanges kicks in, automatically extracts and/or downloads the
  necessary changelogs for all the packages just downloaded, and
  presents just the new parts (relative to the already-installed
  package version).
* After I exit the pager which displays the changelogs, apt-listchanges
  gives me a prompt to confirm whether I want to continue the upgrade
  or not.
* If I say yes, the upgrade proceeds. If I say no, apt-listchanges
  aborts the upgrade process.

This sounds like exactly what you want, handled purely automatically. Do
you not get this behavior (or a comparable one) with apt-listchanges
installed on your system?
