Apple today seeded the first beta of an upcoming tvOS 11.2.5 update to developers for testing purposes, a little over one week after releasing the tvOS 11.2 update.
Designed for the fourth and fifth-generation Apple TV models, the tvOS 11.2.5 developer beta can be downloaded onto the Apple TV via a profile that's installed using Xcode.
We don't yet know what features or changes might be included in the 11.2.5 update, but it likely focuses primarily on bug fixes and performance improvements rather than major outward-facing changes.
The prior update, tvOS 11.2, allows the 4K Apple TV to automatically switch video display modes to match the native frame rate and dynamic range of video content. It also introduced a new Sports section for the dedicated TV app, offering up access to live sports games.
