Apple released tvOS 9.1.1. along with a preview version to bug fixes and performance improvements, it seems that only comes with the novelty of including the Podcasts application. In any case, we already have new software for Apple TV and fourth generation comes six weeks after the launch of the latest public version, which was TVOS 9.1.
The Podcasts app fourth generation Apple TV has 5 sections: Not reproduced, My Podcasts, Featured, successes and Find. Reminiscent of the Music application, but it is understandable that the latter has a slightly more refined image. Keep in mind that the Music application is accessed Apple Music and this is a paid service (or whatever payment worth).
So, still have to wait several weeks to enjoy the novelties of TVOS 9.2, we remember that not let you create folders pare meter applications, will the application picker (multitasking) Like the IOS 9 will allow us to use keyboards Bluetooth, MapKit to add support for applications that make use of maps and Siri learn new languages.
TVOS 9.1 also brought integration with Siri Apple Music, which provides quite comfortably. If we consider that in the first version of TVOS we could not use the Remote application to enter text, all we can say is that the development and implementations of TVOS go slowly and with good lyrics.
