Everything as up-to-date as possible


The following packages are not being upgraded because the new versions conflict with other installed packages:
- ocaml.5.5.0
- ocaml-compiler.5.4.1+lrgrep
-- ocaml-base-compiler.5.4.1 is installed and requires ocaml-compiler = 5.4.1
However, you may "opam upgrade" these packages explicitly at these versions (e.g. "opam upgrade ocaml.5.5.0"), 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 5.4.1+afl ocaml-variants.5.4.1+options ocaml-option-afl
# To update the current shell environment, run: eval $(opam env)
