To help triaging issues with opam packages and OCaml 5.0 (and to give me some time to package my own libraries), I am planning to have another try at an open hacking session on Friday evening starting at 19h00 Paris time. If people are interested to join me to do some live opam package hacking, you are very welcome.
Currently, I am planning to work with a manually updated synchronization note at: Opam package hacking afternoon for OCaml 5: 2022/12/02 - HackMD .
