Apple Seeds First Beta of tvOS 11.3 to Developers

Apple today seeded the first beta of an upcoming tvOS 11.3 update to developers for testing purposes, just a day after releasing the tvOS 11.2.5 update.

Designed for the fourth and fifth-generation Apple TV models, the tvOS 11.3 developer beta can be downloaded onto the Apple TV via a profile that's installed using Xcode.

According to Apple's release notes, tvOS 11.3 includes bug fixes, new features, and security improvements, with a list available below:

- Enhancements to Match Content support.
- Automatic frame rate switching on Apple TV 4th Generation.
- Automatic mode switching for AirPlay video sessions.

tvOS 11.2.5, the previous tvOS update, featured no major outward-facing changes that were noticed by Apple TV users, appearing to instead include minor under-the-hood updates.

Define promise. They told the Verge ('https://www.theverge.com/2017/9/21/16341876/new-apple-tv-4k-review-2017') "the lack of Atmos isn’t a hardware limitation, and that support is on the roadmap." People may have read Apple's words and included that in a buying decision.
Who told the verge? Give me a name?

Essentially the verge asked ‘someone’ at Apple. I could pop into an Apple Genius Bar and get a whole range of information some of which is accurate,some of which isn’t.

This is based on a verge story quoting an unnamed source. It’s no more than hearsay

I hope this goes hand in hand with "Enhancements to Match Content Support". Hopefully auto switching between 720p, 1080p and 4K, as well as frame rate and SDR/HDR/DV.

Unlike Apple TV content which streams the proper resolution for the selected resolution, a Phone or Mac might be playing back a different resolution than the ATV is set to display. Having the ATV auto match the proper resolution would solve all kinds of issues for me.
