iBooks Author Update Adds ePub 3 Export Feature

The iBooks Author 2.3 version released June 19 includes 2 new templates for the creation of ebooks in the epub 3 format. This is important because the iBookstore requires that books in a number of languages use that format (and not the .ibooks format that was the only option in earlier iBA versions). Also epub 3 format can normally be read on a variety of platforms, unlike the .ibooks format
