Mark Cutts confirms there was another update except EMD on this day here: https://twitter.com/mattcutts/status/252484514486575104 However I can't figure out what update this was. Anyone with an idea?

This is precisely the point. So many changes these days it really is impossible to try & work out what is going on & what you can do about it.
