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.5.5.0
- ocaml-config.3
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.
