Following today’s WWDC keynote, Apple has updated iTunes to version 10.3. This update is a beta version that adds the iBookstore to your Mac or PC and music sync that was mentioned in the keynote. There are also multiple user interface tweaks in the new version and other features not mentioned. The update is available at Apple’s site once they decide to take the old 10.2.2 link down and put up the right one, so head there and keep checking back to see.
Additionally, following this release of iTunes 10.3 Apple released iTunes 10.5 to developers. This beta version (b27) adds support for iOS 5 syncing so if you want iOS 5 then you need this on your computer first. The only bug I’ve encountered so far would be on my Mac the window position seems to stay the same every time I quit the app. Instead of moving and staying put when the app is closed, it stays where it was previously. Maybe this is just an issue with mine, please discuss in the comments.
