You will be running CentOS Stream 8.

It is not a rolling release in the sense of .. it moves from Stream 8 to
Stream 9 .. it will be Stream 8 until you manually move to Stream 9 or
we get to the EOL (Currently May 31 2024).

Well .. they will be working on the next RHEL point release.  So the
package will be from 8.4 if the current release is 8.3 and you are
running  CentOS Stream 8.

It would be from 9.2 if the current release was 9.1 and you were on
CentOS Stream 9.
