They don't understand that
docker-1.13.1-204.git0be3e21 > docker-1.13.1-104.git4ef4b30 ?

You could point out that CentOS is a rebuild of RHEL so any RHBAs
posted for a particular version of RHEL7 applies to the same version
in CentOS 7.

https://git.centos.org/rpms/docker/ is where the RPM SPECs, patches
and related files are posted.  For example, the one in Extras is:

https://git.centos.org/rpms/docker/tree/c7-extras and you can see the
commit to import the 104 release here:


You can look at the commit history for the package:

Interestingly, the r104 looks like it failed automatic debranding, and
it didn't get properly debranded until Johnny Hughes manually did it
in r108.  But I doubt that makes any difference in your issue,
although it might have changed any announcements at the time.

I don't see any posts to any lists during the timeframe that it was
imported and published by CentOS.  I'd honestly like to know if
there's any particular rules for how centos-announce posts get
generated too.  I imagine that now that the Stream releases precede
the RHEL package releases, there might be a different set of rules? 

I tried to find something in the wiki but apparently I searched too
many times and it told me to not search so frequently.  Google didn't
show anything though.
