Apple today released iTunes 7.6.1, and announced a new $0.99 Movie of the Week promotion in an email sent out to iTunes Movie Rental customers. According to Apple, iTunes 7.6.1 “includes several bug fixes and improves compatibility with Apple TV software version 2.0.” iTunes 7.6.1 is available now through Apple’s Software Update utility. Separate from the release of iTunes 7.6.1, Apple also officially introduced its new $0.99 Movie of the Week promotion, in which a different movie will be available to rent each week, from Thursday through Monday, for $0.99. Like other rentals, users still have 30 days to begin watching the film. This week’s movie is The Hours; last week, iLounge editor Jesse David Hollington noted a $0.99 rental price on the classic film Breakfast at Tiffany’s, suggesting that the promotion has been going on unannounced for at least a week.
