I'm running Ubuntu and do my regular updates and I wanted to know where can I view a log of what has been changed/updated/fixed with each update.

One way would be to obtain a time-stamped list by opening a terminal with CtrlAltT and issuing the command more /var/log/dpkg.log This will give you more information than you are currently asking for. You can narrow the results considerably using grep for example this command shows packages installed/upgraded on my system as of todays date:

grep "2017-08-21" /var/log/dpkg.log | grep "status installed"

If you want to examine the changelog for a specific package that you have installed you can obtain that information with the command sudo apt-get changelog packagename where packagename is the name of the package.

Example:

sudo apt-get changelog logrotate will provide the change log for the package logrotate

I think this might help point you in the right direction.

sudo apt list --upgradable

It will list all the available upgrades. I know it isn't a changelog, but it will point you to the program version you are going to if you run the upgrade. From there the developer should have a changelog available.

It is clunky but should get you the info.
