I’ve also submitted a project for the winter session: “Create a tool to show differences in the output of odoc.”
The idea is to produce a tool to work on the output of the ocaml-docs-ci pipeline to find differences between different versions of the same package. We’re aiming for it to eventually be used in the docs pages to highlight differences between versions in v3.ocaml.org. Just one of the neat things we’ve got in mind for the docs pages on the new website!
As @tmattio points out, you don’t have to be a mentor to contribute to the process - so let the odoc team know if you’re interested in lending a hand.
