You’re right, we can wait and get more feedback!
If someone decides today to
push tha button and upgrade to CentOS 7.5, the open problems are
- the nDPI and dahdi kernel modules that have been recompiled
- the
nutpackage from EPEL
The same problems occur also for new installations on a fresh CentOS 7.5.
In any case, as workaround I’d suggest How to lock to a specific distribution release
