If Apple’s changelog for iTunes 12.7.2 is anything to go by, this version of iTunes for Windows and Mac is nothing more than a bug fix release which also adds performance improvements to the software to make overall experience better and pleasant than what it was previously. The update apparently also has more focus on music, movies, TV shows, podcasts and audiobooks.
Full official changelog of iTunes 12.7.2 from Apple is as follows:
-This update includes minor app and performance improvements
-The new iTunes focuses on music, movies, TV shows, podcasts, and audiobooks
The last major release of iTunes, which was version 12.7 and released alongside iOS 11 back in September this year, made big changes to how software worked by notably dropping support for built-in App Store for iOS apps, among other things. The company though still maintains and makes available for download a special version of iTunes (version 12.6.3) with built-in App Store and ringtone management support for its customers in businesses and special needs.
iTunes 12.7.2 can be downloaded from apple.com/itunes/download, or directly through different software update mechanisms found in both Windows (Apple Software Update Utility) and Mac (Mac App Store) platforms.
