Running Debian Testing means that I constantly have new packages pushed to my machine. While the majority of these changes cause no problems, occasionally there can be a few hiccups.
apt-listchanges is a useful package that shows any Debian NEWS files during package upgrades. It can also be configured to show the Debian changelogs too. It cleverly displays each changelog version since the version that was previously in Testing (bear in mind that not every package version in Sid reaches Testing).
To enable the changelog behaviour, run
as root, and change the type of notifications from news to both.
This will add an output similar to the one shown below when upgrading packages.
