Hello.
I'm plan update ImageMagick to 6.6.2-0 version in rawhide (
https://bugzilla.redhat.com/show_bug.cgi?id=579458).
Soname bump coming, so, rebuild dependent packages required.
Sorry if it is not interested for you, I sent mail to all from:
repoquery --repoid=rawhide --whatrequires ImageMagick\*
--qf='%{name}-owner(a)fedoraproject.org,'

With best wishes, Pavel Alexeev aka Pahan-Hubbitus.
