I'm happy to announce that we've updated our CentOS Stream 8 repository
pipeline to merge new composes rather than replacing the previous content.
This will give users the ability to `dnf downgrade` packages easily.  Most
packages don't have multiple versions available yet, but going forward more
package versions will be added.  You can see if a package is downgradable by
asking dnf to show the available duplicates.

# dnf --quiet list --available --showduplicates openssh
Available Packages
openssh.x86_64             8.0p1-5.el8              baseos
openssh.x86_64             8.0p1-7.el8              baseos
openssh.x86_64             8.0p1-8.el8              baseos

Due to space limitations we won't be able to keep all packages versions
forever, but the intention is to have at least one downgrade version
available for most packages.  This will make it easier for users to identify
if a recent update caused a regression and file a more detailed bug report.
