You do want a recent Survex version (or a sufficiently old one), but
the reason isn't a format change.

On Microsoft Windows, therion currently assumes that the file
association set for processing .svx files runs cavern, which isn't true
by default for Survex 1.2.23 and later (instead aven is now run).

I added a workaround for this in Survex 1.2.24 - if aven is run in the
invalid way which results from this, it runs cavern instead.  This is
ugly, but shouldn't break anything else and is enough to make therion
happy for now.

So this should only be an issue with Survex 1.2.23.  If you still see
it after upgrading to a newer version, I'd try uninstalling and
reinstalling (I'm not sure if the file associations get updated when
upgrading).

It would be good to fix therion not to make this assumption though.
Aside from the issue above, the user can change file associations to
anything they like.
