Comment 24 for bug 1568459

"This is a real show-stopper. It's not possible to fix this with a new protocol version?"

I think the problem is really, why should different versions of a multi-part solution break a system, and the answer is they shouldn't, at least not between minor versions and ideally all versions should be backwards compatible for at least a few major versions.

Unison is a great program until you want to run it on different systems, and let's face it, none of us want to build from source if there is a compiled package already available. We don't always have a choice in when different machines are upgraded, even updating might need a server restart that you can't do until the weekend but the desktops are all done the same day.

It's a fundamental design flaw. It should be backwardly compatible. Software should ALWAYS be backwardly compatible within minor updates, let alone major ones.
