Once you have downloaded the Aperture 1.5 update (125MB) and then one of the Mac OS X 10.4.8 updates that you need to install first (148MB for me), and then let Aperture loose on your library updating all the thumbnails and previews, you'll be wondering where the new documentation is.

Right now the manuals are on the front page of Apple's Support page for Manuals, but this will change as more manuals get added to the site. You can download the manuals all in one go (about 22MB) as follows:

1. Open the Download window in Safari
2. Highlight the text below
3. Drag and drop it onto the Download window

Update: That user manual is still the same one that shipped with 1.0. Once you are running Aperture, go to Help > User Manual for the latest version.
