I see the Photos app beta is out. I've been holding off on a major clean-up of iPhoto, since I knew this new app would be replacing it and the feature set was unclear. For people who are using this, does it look safe to rename photos, add keywords, attach "faces" and locations, etc., in iPhoto right now, in advance of the new app's official release i.e., does all of the preceding info. transfer over to the new app, or have some of those features been changed or eliminated? Thanks for all feedback.
