Comment 28 for bug 579804

Daniel: Yes, we've implemented this capability in the trunk and it will be present in Shotwell 0.8, which we're planning to release in November. If you want to try this in the trunk build, you'll need to run Shotwell with the --autocommit-metadata command-line option, which tells Shotwell to save tags inside image files (since we haven't built the preferences checkbox to enable this yet). Or you can just wait for 0.8. :)
