Among the most notable updates to come with version 3.0 is the new scrolling feature that displays content in a modified unpaginated layout, allowing users to navigate by "flicking" up and down through text. The endless scrolling lets readers quickly jump forward and back, and removes the restriction of having to wait for page turn animations.
Also added to the iBooks is the ability to view all previous iBookstore purchases from the bookshelf, a feature much like the purchase history seen in the iOS version of iTunes.
