- you won't be able to use mercurial repositories unless you install the hg command on your system.
- you won't be able to use darcs repositories unless you install the darcs command on your system.


This version of opam requires an update to the layout of /home/opam/.opam from version 2.0 to version 2.2, which can't be reverted.
You may want to back it up before going further.

Everything as up-to-date as possible (run with --verbose to show unavailable upgrades).
However, you may "opam upgrade" these packages explicitly, which will ask permission to downgrade or uninstall the conflicting packages.
Nothing to do.

<><> afl-persistent.1.4 installed successfully ><><><><><><><><><><><><><><><><>
=> afl-persistent is installed, but since the current OCaml compiler does
not enable AFL instrumentation by default, most packages will not be
instrumented and fuzzing with afl-fuzz may not be effective.


To globally enable AFL instrumentation, create an OCaml switch like:


opam switch create 5.2.0+afl ocaml-variants.5.2.0+options ocaml-option-afl
# To update the current shell environment, run: eval $(opam env)
