Hi Shengjing! Regarding https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1070160 Could you please consider this request?
Also, I hope you are keeping an eye on https://tracker.debian.org/pkg/fmtlib for potential regressions. I am currently trying to debug why MariaDB no longer builds with latest libfmt version in https://salsa.debian.org/otto/mariadb-server/-/jobs/6534951
