Apple has updated iBooks Author for OS X Yosemite and added support for new file formats and other enhancements. First among these is the ability to import Adobe InDesign and ePub files to a project. New blank templates have been added to accommodate custom designs, and authors can now use hyperlinks to jump to a specific location in other book or add a link to an image.

The app’s widgets have also gotten a few upgrades. Auto-play is now available for the media, Keynote, and HTML widgets, and the HTML widget can now be used directly on the page of a book. The Keynote widget gained improved translation support.

You can download iBooks Author for free on the Mac App Store. The change log is below.
