What’s New in iTunes 6.0.4?

I hate when software programs ask me if I’d like to update, but don’t say anything about what’s coming in the next version. Maybe I’m just paranoid, but I have no idea what’s going to happen, and so I think of the worst. Being unable to revert back to the old version would be terrible. I hope oldversion.com stays updated. I always try to find a changelog when upgrading, and today’s upgrade is iTunes 6. It wants to upgrade to 6.0.4, but what has changed? I’ll update this post when I find out.
