Currently, the normal CentOS Stream repos (AppStream, BaseOS and CRB) keep the last 5 releases of a package.  But the corresponding devel repos, which contain the debuginfo and debugsource packages, keep all the packages.
This has caused these repos to get rather large and has been causing disk space issues for those mirrors that choose to mirror them.

Starting next week, we will start trimming the devel repos the same way we have been trimming the others, only keeping the last 5 releases of each package.  We will not be touching koji, or any other place these packages might be, only the mirrors.
