Apple has released tvOS 13.4 beta 5 to registered developers as well as to public beta testers alongside the beta releases of iOS 13.4, iPadOS 13.4, watchOS 6.2, and macOS Catalina 10.15.4. The build number for this latest beta update is 17L5255a. The ‘a’ at the end of the build number denotes that we are towards the end of the beta cycle of tvOS 13.4.
There are no new major changes that are included in this update. This update will only bring in bug fixes and improvements to your Apple TV. This update will support all devices which support tvOS 13 which are the Apple TV (4th Generation) and the Apple TV 4K (5th Generation).
