Hello again. Forgot to mention the most important part....
Russell Sim, the maintainer of libgit2, is very busy at the moment and would appreciate help. I'll help out getting over the current hurdle with the new upstream release and the transition, but maybe you as the maintainer of libgit2-glib which is closely related to libgit2 would consider helping Russell out on the longer term by becoming a libgit2 co-maintainer? The repo was just moved to collab-maint.... See https://bugs.debian.org/798338 for more background info. Regards, Andreas Henriksson
