I guess there are other people contributing still, but the github page is just a mirror, issues can’t be reported there or anything.

The sole developer isn’t actively supporting Reticulum anymore:

“The software remains available for use as-is. Occasional updates may appear at unpredictable intervals, but there will be no support, no responses to issues, no discussions, and no community management in this or any other public venue. If it doesn’t work for you, it doesn’t work. That is the entire extent of available troubleshooting assistance I can offer you.”
