The Apollo Federation 2 and Gateway 2.0 are now available in preview, offering improved features for building, managing, and scaling unified graphs. The preview includes no breaking changes from the alpha release, with support for `@link` and `@shareable` syntax, and automatic conversion of Federation 1 subgraphs to Federation 2 during composition. To get started, users must upgrade to Gateway 2.0 or higher, turn on Federation 2 composition, and modify their subgraphs at their own pace. The preview is available for those currently using Federation 1, with resources provided to help navigate the transition.
