for i in 1 2; do
  grep-dctrl "" -s Package,Version -n <Packages.$i \
  | paste -s -d "  \n" | sort -u >Pkgs.$i
done

By package:
Removed: cat Pkgs.1 Pkgs.2 Pkgs.2 | sort | uniq -c -W 1 | grep "    1"
Added: cat Pkgs.1 Pkgs.2 Pkgs.2 | sort | uniq -c -W 1 | grep "    2"

By package+version:
Removed: cat Pkgs.1 Pkgs.2 Pkgs.2 | sort | uniq -c | grep "    1"
Added: cat Pkgs.1 Pkgs.2 Pkgs.2 | sort | uniq -c | grep "    2"

The python-apt or apt-python module.
