Not all issues are discovered > right away and may already exist in the previous version. I did this just yesterday, going back to systemd-239-43. I noticed my problem on RHEL, which jumped from 41 to 45, but I am potentially able to write a better ticket by being able to reproduce it in Stream, if I can go back more than one version. Could it make sense to base what versions are made available in Stream on what's between versions in RHEL? I have no concept of the limits on space though, particularly for mirrors. -Laura
