Just as promised during today's iPad mini event, Apple has released the new version of iBooks with better iCloud integration, enhanced sharing options, continuous scrolling, and more.

With iBooks 3.0, now you can see all your iBookstore purchases in iCloud in a new Collection called Purchased Books. Another great new feature of iBooks is the new Scroll theme; it allows you to scroll vertically through your books as you read.

iBooks 3.0 also allows you receive free updates to your purchased books including new chapters and corrections and the ability to look up definitions for words in German, Spanish, French, Japanese and Simplified Chinese. For the social types, you can also share quotes or thoughts about your books with friends on Facebook, Twitter, Messages, or Mail.

So what do you think of the new iBooks? My favorite new feature is vertical scrolling. What about you?
