since yojson 3.0.0 looked like a big version bump from version 2.2.0, I preferred to upload it to experimental, so we can see how it fares.It indeed is. It doesn't get installed naturally in opam-debian-switch. I didn't try hard to force things. I think at least ocaml-atd is broken (there is an open issue on GitHub about that).
I just did an opam-debian-switch run, then installed yojson 3.0.0: atdgen and elpi got removed, but everything else stayed installed.
I also did a direct run installing yojson 3.0.0: atd*, elpi and ppx_deriving_yojson (with tests) were uninstallable due to version constraints. ppx_deriving_yojson (without tests) was installed nonetheless.
The issue for atdgen is: https://github.com/ahrefs/atd/issues/431 Cheers, -- Stéphane
