Apple’s tvOS 26.4 beta cycle is moving along, and Apple has now seeded tvOS 26.4 developer beta 3 for Apple TV testers. This new drop arrives about a week after beta 2, and it carries build number 23L5224d.
Right now, beta 3 looks like a routine iteration aimed at stability and bug fixes rather than a big feature wave, since most of the notable tvOS 26.4 additions showed up earlier in the cycle.

Changes in tvOS 26.4 so far
Apple has already introduced a few user-facing updates in tvOS 26.4 during earlier betas, so beta 3 is mostly expected to refine those.
Here are the main changes already associated with tvOS 26.4:
- Continuous Audio Connection option for HDMI output, aimed at reducing audio dropouts or odd behavior when audio formats change during playback, especially in more complex home theater setups
- More subtitle customization, including easier style switching and additional styling controls while watching content (app support can vary)
- Removal of the iTunes Movies and iTunes TV Shows apps, with everything pushed through the Apple TV app experience
