An extremely random fact I noticed when writing the companion article [1] to this (an OCaml experience report):

    "Docker, Guix and NixOS (stable) all had their first releases
    during 2013, making that a bumper year for packaging aficionados."

Now we get coding agent updates every week, but has there been a similar year since 2013 where multiple great projects all came out at the same time?
