What is the ocaml version supported by opam-bundle 0.4 ?

[UnixJunkie]

Hello,

Which opam and ocaml version is supposed to work seamlessly with the released version
of opam-bundle (0.4 in opam-repository)?

I would like to create a self-installer for some released software using opam-bundle...

Thanks,
F.

pining the development version of opam-bundle works with ocaml 4.12.0
