Apple has seeded OS X Mavericks Developer Preview 5, a release most noted for the debut of iBooks for Mac. Apple announced Mavericks during June's World Wide Developer Conference, and has been releasing a series of beta developer previews to developers for testing.
iBooks for Mac is a long-awaited app, and its inclusion in Developer Preview 5 is a welcome sight. A tour published by 9to5Mac shows that the app drops much of the skeuomorphism of the iOS version of iBooks, presenting your library on a plain white background, rather than on book shelves.
Curiously, iBooks in the iOS developer seeds remains untouched as of iOS 7 beta 5, the only Apple app that has yet to be updated in the developer seeds of iOS 7. It's a reasonable bet that Apple will be following the design cues as shown in the Mavericks preview.

Also including in OS X Mavericks Developer Preview 5 is a new version iPhoto (version 9.4.6) and various and sundry performance improvements.
Mavericks is scheduled to be released this fall, as is iOS 7, which is going to make the fall a fun times for us geeks.
