I am (mostly) retiring my git and fossil webinterface.
Future release of source code will happen directly as tarballs. For the future I might re-release some of the source repositories, once I'm done with my mercurial/hg implementation. Everything which needs a significant amount of colab will be handled as exceptions.
As for all other ongoing projects, I don't have the time to write about updates. In addition to university and my current work, I have a a couple very long term projects going on which might see releases.
But I might as well not retire c.n0.is as having some kind of portfolio is expected to be the default, even though a large part of your portfolio is out there on friends servers and part of Operating System projects. If it disappears, it disappears.
