Did Yahoo Change their Homepage?

Yahoo homepage provides popular, interesting and relevant content in a self-contained web experience that offers you to get the most out of your day. And Yahoo is testing new home pages for quite some time.
There are two variations of the new Yahoo homepage designs, one that is released in Sep 2008 and the other that is released in May 2009.
Yahoo! also allows you to change your viewing format between "compact" and "full" according to your preferences or monitor size.
This is helpful if you a narrower monitor and want to limit the screen real estate used or if you have a wide-screen monitor and want to view more information width-wise.
