Perhaps the biggest improvement is the new "Surfer" style (screenshot) I mentioned last month, which enables customizing the grouping and sorting from within the newspaper itself. You'll also be able to flag items or copy them to news bins from within the newspaper - great for those like myself who run FeedDemon with the news item list hidden.
My favorite feature, though, is how the Surfer style enables you to choose between full, short and no descriptions. I prefer using short descriptions, which are basically the first two lines of an item's description with all HTML except hyperlinks removed. This "river of news" approach enables viewing a large number of items at once, so I can quickly scan several feeds looking for items of interest.
