visual.conf (partial):

Equiv   dashArray:3-3

The expected behavior is that if arrowHead:none does not appear in visual.conf, arrowheads are drawn symmetrically on both sides for symmetric relations.

I don't think it was a regression - it was a consequence of Equiv's arrowHead not being defined, and the default was simply not very good.

Another problem that I have no clue how it survived so far: symmetric relations were not being discovered as symmetric, since we're looking up that information in several places and the one that doesn't have this information was coming up sooner. I knew the split between events and relations will be trouble. :)

Okay, assuming that if something is a relation it can't have meaningful info on span definitions, see if this works for you.

Thanks, works for me now.
