Apple has seeded the first developer betas of watchOS 27.2, tvOS 27.2, visionOS 27.2, and HomePod Software 27.2 for testing.
Today's releases carry build numbers 24S5086l for watchOS, 24K5088l for tvOS, and 24N5088l for visionOS.
Apple has not yet detailed the changes in these builds. We are installing the updates now and will report back with any notable features or changes we discover.
The watchOS beta can be installed through the Watch app on a paired iPhone with Developer Beta enabled under Beta Updates. The tvOS beta is available from the Software Updates section of the Settings app on Apple TV. The visionOS beta can be installed from Settings > General > Software Update on Apple Vision Pro. HomePod beta updates are managed through the Home app on a connected iPhone, iPad, or Mac.
Developers can also download the new software from the Apple Developer Center.
