Hi Lucas, I'm managing the long-overdue release of Autoconf 2.70, we just put out a second beta and I am thinking that it would be interesting to do a Debian archive rebuild with it and see what breaks. I was advised to contact you. The release announcement is at https://lists.gnu.org/archive/html/autoconf/2020-09/msg00006.html and the tarball + signature are at https://alpha.gnu.org/gnu/autoconf/autoconf-2.69c.tar.xz{,.sig}. What can I do to help make this happen? N.B. I am not a Debian developer. Thanks, zw
