Sends, replies and clicks now show up within a few minutes. Ken reads them live and refreshes them about every 3 minutes on the Dashboard and its charts, the Campaigns list and each campaign's Analytics tab.
Before, these numbers waited for a nightly rollup, so during the day you saw yesterday's figures.
Two dashboard charts are fixed with it. Emails Sent no longer shows 0 for recent days, and Contacted counts each person on the day Ken first reached them.
Segment analytics and the correction that removes bot clicks still update once a day.
