Grafoscopio  has been ported to Pharo8.x and Git. Source code and
documentation[3a] repositories reflect the change (at some point I
hope both could be integrated in Fossil, but meanwhile community hosted
Gitea and Fossil are working pretty fine).
For the Grafoscopio 2.x series I hope to update several other things
including migration to Spec2 and improved usability.
ps: We are experiencing some issues with our Gitea instance today. That
should be solved soon or I hope to provide a non-oligopolistic
alternative in the future.
