The Podcast app will allow owners of the fourth gen Apple TV set-top box to listen to podcasts via iTunes. The app automatically synchronizes subscriptions via iCloud.
tvOS 9.1.1 can be downloaded via the Settings app on the fourth-generation Apple TV. Go to the System app, then to Software Update (under the Maintenance subhead.)
