The apt-listchanges tool can almost certainly do the job, if you have the .deb file available. I don't usually invoke it directly, since I don't usually have that file on hand when I want this information, but it's probably relatively straightforward. If you don't have the .deb file available (and don't want to go out of your way to download it first), you're probably left with looking on the Debian Website. Specifically, you probably want to go to https://packages.debian.org/[section]/[packagename] (where [section] is e.g. 'stable' or 'testing' or 'unstable', and 'packagename' is the name of the binary package involved), and then look at the "Debian Changelog" link in the right-hand sidebar. So if you're trying to look at the changelog for the version of the package 'packagekit' that is available through current Debian testing, you would go to https://packages.debian.org/testing/packagekit and follow the link from there. -- The Wanderer The reasonable man adapts himself to the world; the unreasonable one persists in trying to adapt the world to himself.
