Only two weeks after the release of iTunes 12.4.2, Apple has released iTunes 12.4.3, a minor update intended to address a specific bug that caused changes made to playlists on an iPhone, iPad, or iPod touch to not synchronize back to iTunes.
Earlier this month, iTunes 12.5 also began appearing for users running the macOS Sierra developer and public betas, appearing mostly to add support for optimization features in macOS Sierra and Apple Music features in iOS 10; it’s unclear if the playlist syncing bug has been fixed in the iTunes 12.5 betas or not.
