It'll soon be version 1.0.7.  You'll probably be interested to note
that, for some problems, this also significantly decreases the number
of iterations required to find the minimum.  The log barrier algorithm
now converges much more quickly.  Hence this speeds up the dispersion
analyses as well.

Regards,

Edward
