AT&T Galaxy S8 How do I know what is new in Oreo updates?

[DerHof]

So my phone updated to Oreo a couple weeks ago... and like many people there are some things I hate about it.
Today I get a popup telling me there is another update... but it never gives any details.
So for now I have wifi disabled.
Anyway I can find out what it plans on doing before I update?

This second update may be the March security update.

Perhaps... but it would be nice to be able to look over the updates like you can do with regular app in the Play store.
