interface on cycles rendering

I had to download a new copy of blender and I do not see the old way of rendering in cycles. I see only progressive, Seed, clamp and of course render, how do I use those. Did i hit the wrong button somewhere,or is this the new way to render cycles??

Cycles is still in development, expect it to constantly evolve until there is a more stable version in the future.
