Yes, unison has always been very peculiar about which other version of unison it works with. Nowadays unison is also in "bug fixes only" mode it seems, and the developers now apparently only ever test the latest version of unison with the latest version of ocaml; for any other combination you're on your own. >+ Keep the host at 6.5 (until Unison Window's binaries catch up.) I don't know where you got those Windows binaries but IMHO you're better off updating OpenBSD to 6.6 and creating your own Windows binaries. >+ Compile Unison on Windows with a compatible OCAML. That's what I did. Get cygwin (with gcc), compile the latest version of ocaml (4.09.0), then compile the latest version of unison (use git or get the zip file for the latest version directly from github.com; do not try to use previous official releases of unison because they won't work with the latest version of ocaml). When compiling unison you will get some warnings about deprecated APIs but it worked fine for me in the end. FYI, I ended up doing the same thing on Linux too (because I like pain, apparently) and it worked fine too. >+ Build Unison on 6.6 with a lower OCAML version (4.07 seems to work.) You can try that too but you'll basically be on your own if something breaks: the unison devs will just tell you to upgrade. Philippe
