I just tried

    opam update
    opam switch 4.02.2+rc1
    eval `opam config env`
    opam install oasis

and got that message (camlp4 strikes again!):

    The following dependencies couldn't be met:
      - oasis -> extlib = 1.5.3 -> camlp4
      - oasis -> ocaml-data-notation | ocaml-data-notation >= 0.0.11 ->
    type_conv = 108.00.02 | type_conv >= 108.07.01 -> camlp4
    Your request can't be satisfied:
      - camlp4 is not available because it requires OCaml >= 4.03.0.

Cheers!
