Today's iTunes update can be downloaded from the Mac App Store for free using the Software Update function.
iTunes 12.7.2 follows iTunes 12.7.1, an October update that also focused on minor improvements. iTunes 12.7, released in September, was the last major update to iTunes, eliminating the built-in App Store to focus solely on music, movies, TV shows, podcasts, and audiobooks.
