[syslog-ng] Redhat repo

I have a question about the Redhat repo for the unofficial OSE builds. It seems as though they are tied to a specific version. For example, I'm currently using czanik-syslog-ng318epel6, however, I see that 3.19 has a different repo specifically for that version. This seems to be counter to the point of yum repositories and it imposes an additional maintenance burden. Am I maybe not properly understanding how it works, and if not, is there a repo that tracks with the latest stable version? -Mark
