Chwilę po udostępnieniu finalnej wersji iTunes 10.5, do deweloperów powędrowała wersja iTunes 10.5.1 beta z iTunes Match. Tym razem co dziwne w przypadku bety jest to wersja zarówno dla Mac OS jak i Windows oraz co jeszcze bardziej dziwne wersja działa w języku polskim. Pełna lista zmian (która wyjaśnia trochę na temat usługi iTunes Match) w 10.5.1 to:

iTunes 10.5.1 beta 1 includes several performance enhancements and bug fixes, and is a required update for all subscribers to iTunes Match beta. iTunes Match is not included in the iTunes 10.5 GM release.
