Apple has released a ninth beta build of iTunes 10.5 to developers. The build also includes iTunes Match, allowing Apple to solicit feedback about the new service from developers. iTunes Match currently is only available to developers in the United States.
This is the second time that a beta build of iTunes 10.5 has been released separately from the routine updates to the builds of iOS 5, which has been at beta 7 since August 31st. As with the previous builds of iTunes 10.5, a Mac is required to install the build -- Windows builds have not been released.
The beta is available to registered developers at the Apple Developer Center.
