Apple today seeded the fourth beta of an upcoming tvOS 11.2.5 update to developers for testing purposes, one week after seeding the third beta and almost a month after the release of tvOS 11.2.1, an update that introduced a fix for a HomeKit vulnerability.
Designed for the fourth and fifth-generation Apple TV models, the new 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 tvOS 11.2.5 update, but it likely focuses primarily on bug fixes and performance improvements rather than major outward-facing changes.
There were no outward-facing changes discovered in the first three developer betas, but we'll update this post should new features be found in the fourth beta.
Update: Apple has also seeded a new public beta of tvOS 11.2.5 to public beta testers.
