i think this was the first incompatible revision that has been released.
is that correct?

i know we're in early days with wireguard, and there's no guarantee of
protocol compatibility.  but i wonder whether we should signal
explicitly when there is an update that requires both sides to upgrade
at the same time.  Should i have put it in the NEWS file in the debian
package, for example?  Or are there other forms of signalling that we
should use to communicate this better?
