List of unneeded files?

[Aron Stansvik]

Hello.

I just upgraded my 5.2.1-RELEASE laptop to 5.3-RELEASE, all went fine
but I have a question: Is there a list of the files installed by 5.2.1-RELEASE
that are not installed/needed by the 5.3-RELEASE? If there isn't, why not?

I've looked through the Release Notes and Migration Guide without finding
anything like this, I can't say it feels like a "clean upgrade" until
those files
are gone.

Best regards,
