I really like the new look.   It's still light and well spaced but it looks more refined at the same time.

I noticed some minor visual bugs with the new design. Nothing exactly critical but I felt like sharing.

When reloading a page using Firefox 5, I can see the page with no CSS at all flash quickly before it's fully rendered.  It's as if the CSS was applied only after everything is dowloaded.    I only get this problem in FF, Chrome and IE both render the CSS instantly.    

IE has a few different rendering issues like some stuff overlapping but frankly, it's to be expected with IE.  If I was in your place, I would ignore most IE issues.

When simulating a smaller screen, the "statistic line" that tells us the BTC value, hash rate and donation will overlap with the pool name on the left.   This happens in all 3 browsers I tested.

Keep up the good work!  The site is only getting better and better.

EDIT: One more little thing, I think that the monospaced text on the donation page (osList) is a little hard to read with the default font size values.  The size could probably be increased a little.
