Renewal FAFSA for 2008-2009?

Aah, I am so confused. When I look online at the fafsa website, it has only three choices renewal fafsa 2007-2008, fafsa 2007-2008, and fafsa 2008-2009. I need to fill out the fafsa 2008-2009, but I read somewhere I can fill out a renewal one that is easier. What is the difference between a renewal one and the regular one and is the option fafsa 2008-2009 the renewal option, just not explicitly stated?
