Shotwell 0.93 features bugfixes for users of Gnome 3. Since Fedora 15 is shipping with Gnome 3 as the default shell, I think it would be useful to have this version available in the repositories.
Please check http://koji.fedoraproject.org and http://admin.fedoraproject.org/updates for updates before filing bug reports. Shotwell 0.9.2 is already in updates-testing repository yum --enablerepo=updates-testing update shotwell https://admin.fedoraproject.org/updates/shotwell-0.9.2-1.fc15
I did check koji and 0.93 is NOT there. The package you reference, 0.92, does not include the bugfix(es) for Gnome 3.
