Last time (ca. 1 year ago) I tried learning OCaml, I ended up reading the beta version of Real World OCaml 2nd Ed. IIRC and for some reason all I remember now is that I didn't feel confident regarding the learning material.
The RWO-website https://dev.realworldocaml.org claims that the 2nd. Ed. has been published in Q4 2021, but I can't find it anywhere.
Can somebody with experience tell me if RWO 2nd Ed. is the way to go?
