Apple upgrades TestFlight, allowing developers more control over beta testing and inviting new features. The redesigned invites provide more information about the app, helping testers decide if they want to join the test group. Developers can set criteria for testing, narrowing their groups to specific audiences. This update aims to make it easier for developers to target their betas and gain feedback ahead of public release.
