Pacman to upgrade only when version changes

So I was thinking if there is any efficient way to only upgrade when the version changes and not for all bug-fix update. This is of course when the dependencies are resolved in either cases.

For example I don’t want to upgrade pkg_abc 7.12.2-3 -> 7.12.3-1 but only packages with pkg_xyz 7.12.3-1 -> 7.16.0.-2

This is mostly for fun experiments so no need to worry about breaking my system :wink:
