Since other people might be affected by this, it looks like OCaml has changed the marshalling format or similar (again...), so Unison from -current is now incompatible with -stable. I doubt there's anything we can do about this except, perhaps, a) add a warning to the upgrade page b) maybe expand pkg/README to spell out the commands needed to install Unison via OPAM. Laurie
