Apple Releases OS X Mavericks Developer Preview 5 with iBooks App

Apple has seeded the fifth Developer Preview of OS X Mavericks to developers, approximately two weeks after the release of the fourth developer preview. The release comes as Apple continues to work on restoring full functionality to its Developer Center after bringing software downloads back online last week.

This build, ignoring the normal "Safari is snappier" jokes, is ridiculously fast. I don't know what they've done under the hood, but damn they've done a good job of whatever they've done.

Preview doesn't sync with anything on iOS. They should just kill it and roll all its features into iBooks.

Including things like opening and editing graphics files? That would be an odd addition to iBooks.
