Apple has seeded another iOS 5 beta to developers. Beta 7 brings along some big fixes and other improvements to help with user experience. The full change log can be found below.

Accounts

• When creating an iCloud account, you can use any Apple ID as long as it is a full email address and not a MobileMe account. If you have a MobileMe account, you can move that account to iCloud. You can find more information on iCloud at: http://developer.apple.com/icloud

AirPlay

• Starting in iOS 5, video content in applications and websites are AirPlay-enabled by default.
• iOS 5 supports AirPlay of video via AV Foundation.

API Validation

• NEW: Starting in iOS 5.0 development tools beta 7, it is possible to extract APIs used by an application and have them checked for private APIs usage. This option will be offered at Validation time.

Apple TV

• Apple TV Software beta enables users to mirror the contents of an iPad 2 to an Apple TV (2nd generation) using AirPlay. This beta software also enables Photo Stream on Apple TV so users can access photos stored in iCloud. Apple TV Software beta is being provided to test the latest AirPlay functionality with your iOS 5 apps and web sites. If you wish to install Apple TV Software beta on your device, you must first register your device UDID in the iOS Developer Program Portal.
• Slideshow settings are not remembered for slideshow playback (always plays back in Reflections theme). Screen savers settings are behaving properly.
