The main dependence of Appimage is libc version, so CinelerraGG-<CinVersion>libc<LibcVersion>.<Arch> or something similar will be a good name. Is rpm, deb packages of current CinGG are available for download?
The last rpm and deb packages are still October 31, 2020. I do not think I will be able to figure out XEN to continue to build them all -- it was all automated but a different partition has to be booted on the Epyc computer to get to them and I don't have the expertise to understand it well enough at this time. This may change but combining all of the suggestions for the AppImage names leads to: CinGG-20210224-x86-64.AppImage newer distros CinGG-20210224-x64-64_older_distros.AppImage older distros CinGG-20210224-i686.AppImage 32-bit with the assumption that these are all older distros if 32-bit maybe "CinGG" should be "cinelerraGG" instead ? but at least the 5.1 is eliminated maybe incorporate the libc version ? the problem with this is that 90% of the users would not even know what this means.
