Best conversions day in a while yesterday here too, one of our sites that has been dead for weeks came back to life this morning too. Far too early to tell if this is coincidence or related to any updates. Traffic is actually down for us but it seems better quality which is what matters. Can't see any big changes in the SERP's mind.
