Highlights
This update is available through two release phases: gradual rollout and normal rollout. A gradual rollout delivers an update in phases, so features reach devices over time instead of all at once, meaning availability varies by device.​​​​​​​​​​​​​ A normal rollout is the broad release to all eligible devices at the same time, usually when it reaches general availability (GA).
