What's new for Analysis Services users in Excel 2010?

I downloaded the Technical Preview for Office 2010 a few days ago, and was intending to blog about it as soon as possible but a few things made me wait a bit. First of all, there was the problem of whether I was in fact allowed to blog about it at all (which a lot of other people also seem confused about – which explains the strange silence on the web about it, perhaps); then there was the problem of actually finding what the new functionality was, since the Office team had neglected to provide any kind of detailed list of what has been added. Hmm. I think they’re planning to blog about everything that’s new soon though.
