Yes, it seems the newest package has not been built from current GIT.

What's also strange is that I see libxml2 two times, in
centos/7.9.2009/updates/x86_64/Packages/ and in
centos/7.9.2009/os/x86_64/Packages/. Both with identical version but
_different_ builds.

Maybe some automated thing which went wrong?
