I had mail contact with one of the authors today and also talked to
someone who was at the talk, it's basically "just" the final version of
the paper that was preprint-released last year.

I think the press release is vastly overblown. This still only affects
finite fields of small characteristics, which is not really relevant
for crypto.

Yeah, I agree on that. I don't see the Joux et all results really
frightening, as most people I ask seem to think that they don't apply
to any real-world crypto. But the quantum threat is looming and became
much more likely in recent years.
