The unison package in Fedora 8 was recently updated to an incompatible

I assume I'm correct in saying this was the wrong thing to do. What is
other people's take on this?
Upstream should be dragged out into the street and shot.

Forget the :). If you can't keep your wire protocol compatible, it's
not the same program anymore so just change the name and stop confusing
everyone. And if you are inventing something new, please exchange a
protocol level indicator so you'll be able to support different remote
versions later instead of forcing the whole world to change on the same
day.
I've used unison for awhile, and quite frankly this happens all the time. To
handle consistent sync you need to match the versions being used on both sides
exactly and keep them there. I've had it break numerous times changing versions
within 'compatible' version ranges. Changing those versions means you have to
take what currently exists and assume it is in sync the first time you run the
new version. This is just how things have been going with unison.
