Apple updates iBooks Author with support for multitouch widgets, OTA book updates

Apple used its press event today to introduce a new version of iBooks Author. The latest version of the book authoring tool lets users embed custom fonts, insert mathematical equations into a book and add multitouch widgets. There's also over-the-air book updates and a handful of new templates including some for portrait mode.

iBooks Author is available for free in the Mac App Store. The latest update will be available later today.
