Hi, is there anything in OCaml 4 that should break old code? Looking at the release announcement it sounds like the language changes are backward compatible. I would expect everything to just work (except of course using the builtin marshalling between OCaml 4 and 3.x applications).
That's what I thought too, but I've already had to update some packages, net/ocamlnet for example. Sometimes breakage is also just caused by the fact that things are installed in different places (the compiler libraries, for one, which breaks devel/ocaml-findlib).
So yes, most packages should continue to work without problems, but still, some breakage is to be expected...
