apt-listchanges is triggered as a pre-hook to "apt install" (not as a 
post-hook to "apt update").  By default is shows NEWS entries since the 
already-installed release of same package, but can be changes to 
also/instead show all packaging changes.

Related is also needrestart, or needrestart-session for desktop systems.
