Apple has followed up the release of the first iOS 11.3 and tvOS 11.3 developer betas earlier this week with the first beta of watchOS 4.3. Featuring a build number of 15T5165e, the very sparse release notes list only basic background information and “No known issues” providing no insight into what’s actually changed in the newest version.
In addition, Apple has also released the first public betas of iOS 11.3 and tvOS 11.3 through its Beta Software Program, allowing non-developers to get a sneak peek at the plethora of changes coming in iOS 11.3, including new Animoji for iPhone X users, improved battery health monitoring, and Messages in iCloud.
