A general point on the [0/N] intro. Bear in mind that this is (intended to be) for ever. Five years hence, people won't be interested in knowing which version the patchset was, in seeing what changed from the previous iteration, etc. This is all important and useful info, of course. But it's best suited for being below the "^---$" separator. Also, those five-years-from-now people won't want to have to go click on some link to find the performance testing results and suchlike. It's better to paste such important info right into their faces.
