As someone has already pointed out, a better way is
emerge sync && emerge -uDav world
That way emerge doesn't have to caculate the dependencies again (because you should always see what emerge is about to do before upgrading) and you get to see how big the updates are before downloading them.
While I agree with the parent poster in saying that you will always be up to date (as often as you run emerge sync; emerge -Duav world) I don't agree with the poster in saying that the releases don't deserve a place on the front page. The reasons that the releases are important is two fold: 1. Installing a new system. While true that you could start from an earlier edition of a live cd and emerge the updates, most likely it will take you a significantly more time to update your system than it would if you had started from a newer version of the LiveCD. 2. The LiveCD team is always improving on hardware recongnition and ease of installation (though allot of people think that the installation still needs to be improved). What might not work with an earlier LiveCD may work with a current one.

Thanks.
