iTunes 9.1 will arrive alongside the iPad on Saturday, bringing with it a number of changes, many related to the new features of the latest iTunes-connecting device, Mac Rumors reports.
Most notably, iTunes 9.1 will offer support for ebook files, and will see the “Audiobooks” listing on the iTunes Store and in the content management interface for connected devices changed to a broader “Books” section that will display all book content compatible with the currently connected device.
Other changes will include greater control over Genius Mixes, including the ability to rename, rearrange, and delete Mixes, slight changes to device support, including small interface tweaks to the summary panes, and expansion of the ability to automatically convert songs to 128 kbps AAC format when syncing to devices.
