iTunes 12.5.3 was released by Apple last night, shortly after iOS 10.1.1 si iOS beta 10.2 1 were made available to developers and users. For this build of the iTunes application, Apple has listed exactly the same list of changes that it listed for iTunes 12.5.2, so there is no news.
Considering the fact that Apple does not list any other changes for this version of the iTunes program, it is clear that we are only talking about a solution to a minor problem. You can install iTunes 12.5.3 using the existing Software Update program in Windows or macOS, or by downloading the program directly from the Apple website.
