Version 3.1 of iBooks is out today and while it might not bring much in the way of new features for Western users, it's a pretty big deal for book lovers located in Japan. That's because the latest update introduces paid content on the order of hundred of thousands of books -- encompassing novels, manga and more -- something that the country's iBookstore has been without up until this point. Before now, iOS users in Japan have needed to be content with public domain e-books.

In addition to the paid content rollout, the 3.1 update also introduces some improvements when reading Asian language books.
