Trying it out during the preview

During the preview, the following steps are required to try new features:

1. Update the @link directives to point to federation/v2.11 and connect/v0.2:

   extend schema
     @link(url: "https://specs.apollo.dev/federation/v2.11")
     @link(url: "https://specs.apollo.dev/connect/v0.2", import: ["@source", "@connect"])

2. Opt into the preview with this router YAML configuration:

   connectors:
     preview_connect_v0_2: true

3. Use Router v2.2.0-preview.0

   export APOLLO_ROVER_DEV_ROUTER_VERSION=2.2.0-preview.0
   rover dev

4. Use Federation 2.11.0-preview.0 for composition:
   • In supergraph.yaml:

     federation_version: =2.11.0-preview.0
     subgraphs:
       products:
         # ...

   • In GraphOS, choose the "Federation Next" build pipeline version from the Variant settings page:
