Description Carl George 🎩 2026-03-16 22:01:24 UTC 
Description of problem:
The current version of qt5-doctools in EPEL 10.2 and 10.2 was built against libclang 20.  libclang has been updated to 21 in CentOS 10, which is also expected to land in RHEL 10.2 soon.  To avoid installation and upgrade problems, qt5-doctools needs to be rebuilt.

This was a typo, and should have been EPEL 10.2 and 10.3.  Sorry for any confusion due to that.
