iTunes 11.1.5 is just a small update that fixes a single issue that could cause iTunes to quit unexpectedly when a device was connected. Apple also improved compatibility with iBooks for Mac in OS X Mavericks. You can download the new version of iTunes in the Mac App Store or directly on the Apple website.
