iBooks update

Apple's iBooks has been updated:

• Double-tap an image within a book to view it in greater detail.
• Experience books that include audio and video.
• Enjoy substantial performance improvements when reading PDFs.
• Look-up definitions to English words inside books without a specified language.
• Addresses an issue that may have caused some book downloads to not complete.
• Includes many stability and performance improvements.

Personally I still think that the store is what let's down this app. Not just because so far I've yet to find anything that I actually want on it, but the prices are way too high.
