@antoneri @danieledler If you are planning a new major release, would you be willing to take a couple of days so we can explore, together, whether some of the changes we have to make in the igraph-vendored version of Infomap could be integrated here? I am hoping that we could reduce the differences between the official version and the version vendored in igraph, to make maintenance easier for us at igraph.
