Please branch and build range-v3 in epel10. If you do not wish to maintain range-v3 in epel10, or do not think you will be able to do this in a timely manner, I would be happy to be a co-maintainer of the package (FAS slaanesh); please add me through https://src.fedoraproject.org/rpms/range-v3/adduser
The latest version currently in rawhide/f42/f41 builds fine as-is in epel10.
Will you be able to branch and build range-v3 in epel10? I would be happy to be a co-maintainer if you do not wish to build it on epel10 (FAS: slaanesh).
