Apple has released a new beta of iTunes 10.5 to developers this afternoon, re-enabling some iTunes Match functionalities that have gone missing after the iCloud music library reset that several developers reported on Apple’s Dev Forums this week. iTunes 10.5 beta 9, available now, contains bug fixes and improvements over iTunes 10.5 beta 8, which was seeded earlier this month.
iTunes 10.5 is required to sync devices running iOS 5, and it brings a number of optimizations and improvements to iTunes’ code, which now runs natively at 64-bit on Lion. The first beta of iTunes 10.5 that implemented support for iTunes Match – Apple’s upcoming backup and scan & match service for music in the cloud – was seeded in late August.
iTunes Match will launch this Fall alongside iCloud, and it will be compatible with OS X and iOS 5 devices.
