Apple has released iTunes 9.0.1 for Mac OS X 10.4.11 or later, Mac OS X Server 10.4.11 or later, Windows XP, Vista, and the Vista service pack that Microsoft refers to as “Windows 7.”
iTunes 9.0.1 provides a number of important bug fixes, including:
• Resolves issues browsing the iTunes Store.
• Addresses a performance issue where iTunes may become unresponsive.
• Fixes a problem where iTunes may unexpectedly quit.
• Fixes a problem syncing Podcasts in playlists to iPod or iPhone.
• Fixes a problem sorting albums with multiple discs.
• Addresses an issue with the Zoom button not switching to Mini Player.
• Improves application syncing for iPod touch and iPhone.
