Comment (by cremona):
Thanks, Chris. Of course there may well still be bugs, as always. The
code was tested against completely independent determination of complete
isogeny classes for a lot of curves over Q(sqrt(5)) and the cubic field of
discriminant -23, and we find the same curves. That did not test the
hardest part (namely the CM cases) though where I have done some
systematic testing over imaginary quadratic fields of class number 1.
