Hi Andreas, Many thanks for taking care of the 3.9 series! I am confused of the 'vendor/' directory in tag 'upstream/3.9.5+ds1'. The upstream release at https://github.com/sylabs/singularity/releases/tag/v3.9.5 does not have the directory anymore. Neither does the git repo https://github.com/sylabs/singularity What mechanism are we using to re-vendor things into the +ds tarballs? Cheers, Benda
