I dont agree. These are important messages for all installs.

Welcome

There are three other messages that could be displayed and they are only displayed in certain specific upgrades

Then it would be a completely different page, that is not bound to changes in a specific version but like a docs page for the first steps or something like that.

If you want to submit a PR for that then go ahead - personally I dont see the need

Maybe this whole topic should be discussed first. What would be an important After Install Message. Is it something that makes an impact for me when i upgrade from a lower version? Then only After Installation Messages should be shown that affect me because of that changes. If it's a "Welcome Page" with the most important things, then we could extend it and change the layout and list all ressources (Volunteers Portal, Docs, Ressources Directory, and and and).

please folks, help me with my bad english:
install is not equal to upgrade nor is equal to update
?
please clarify

install = new
upgrade/update = change from an older version

my binary mind is now happy ?
....jokes apart.....
so postinstall should be postupgrade
or i'm still too naive ?

From what i understand, the messages show what significant and important changed in a certain version. So i would agree that this a post upgrade messages. They are shown always. I leave it open to a discussion if the way it's done now is good or not. In my opinion it should show up after the ugrade only and not after each install and force the user to go somewhere and click everything away.

This PR #19958 would be a good compromise.
