between the versions 1.1.0 and 2.0.0, data.json introduced a breaking change: The JSONWriter#-write signature changed from [object out] to [object out options]
On this commit:
https://github.com/clojure/data.json/commit/8f070ba94dc7c469f303259ce5f5bfa0b53d50bd
In release notes Release 2.0.0 on 2021-Mar-19 , there is no mention to JSONWriter or -write protocol changes.
I know it's a very old problem, but I think this documentation could be present.
