Everything as up-to-date as possible (run with --verbose to show unavailable upgrades).
The following packages are not being upgraded because the new versions conflict with other installed packages:
- ocaml.5.4.0
However, you may "opam upgrade" these packages explicitly, which will ask permission to downgrade or uninstall the conflicting packages.
Nothing to do.

=> 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.
