(How) can you display update release notes in a terminal?

When using the graphical Software Updater, I can display release notes for updates that have them.
However I prefer doing updates in a terminal, but apt does not seem to be able to do this.
Is there any command-line tool that can display update release notes?

Here’s two commands you could use:

apt changelog <package>
aptitude changelog <package>

This gets them from http://changelogs.ubuntu.com, but sadly I couldn’t get them to fetch anything for packages like ubuntu-mate-desktop or ubuntu-mate-welcome, but it’ll work for official Ubuntu packages, like unity.

Alternately, you could write a function that does some page scraping and grab the changelog from Launchpad. For example, for ubuntu-mate-welcome version 16.10.11: https://launchpad.net/ubuntu/+source/ubuntu-mate-welcome/16.10.11
