Hi @SnarkBoojum!

Sorry for the very late response, and thank you very much for your patch. The support for Yojson 2 was added as a side-effect of f87190d. The lower bound for Yojson was only put to 1.6.0 because that is sufficient for Yojson.Safe.t to exist. However, latest runs of the CI definitely chose Yojson 2.0.2 from OPAM.

Best,

Note that version 0.11.0 is now out and it includes the support for Yojson 2.
