I plan on updating OIIO to the 2.0.3 release this weekend for rawhide after completing test builds of dependencies. This includes a soname bump and there are some small API changes.

LuxRender-1.6-26.fc28.src.rpm
OpenColorIO-1.1.0-9.fc30.src.rpm
OpenImageIO-1.8.17-1.fc30.src.rpm
blender-2.79b-9.fc30.src.rpm

I'm open to updating F29 if someone needs it but not planning to at this time.

Thanks,
Richard
