 ## What's Next
 
-### Federation 2 GA
+### Next Release
 
-* Incorporate community feedback on Preview
-* Type merging that can be relaxed even further with:
-  * `@inaccessible` - [#1178](https://github.com/apollographql/federation/issues/1178) and [core feature spec](https://specs.apollo.dev/)
-* Field migration across subgraphs with `@override` - [#1177](https://github.com/apollographql/federation/issues/1177)
-* Updated [Fed 2 docs](https://www.apollographql.com/docs/federation/v2/) & [migration guide](https://www.apollographql.com/docs/federation/v2/federation-2/moving-to-federation-2)
-* Enhanced test automation
+* `@tag` export to API schema
+* Compose user-defined directives in subgraphs
 
-### Federation 2 Post-GA
+### Under Consideration
 
-* Compose user-defined directives in subgraphs
+* `@defer` support in query planning
+* Subscriptions support in query planning
+* Entity interfaces can be spread across multiple subgraphs & interface queries with `@interfaceObject` helper.
 * Harmonizing shared value types across subgraphs to a canonical desired state.
 * Advanced caching, auth, demand control, rate limiting, governance, and more!
 * Importing shared types into subgraph schemas, to keep things more DRY.
-* `Entity interfaces` can be spread across multiple subgraphs & interface queries.
-* Nested `@provides` support beyond what Fed 2 alpha already supports natively.
+* Nested `@provides` support beyond what Fed 2 already supports natively.
 * Process subgraph and supergraph schemas with a new [core-schema-js](https://github.com/apollographql/core-schema-js) library.
 * Expanded use of [core schemas](https://github.com/apollographql/core-schema-js) to compose your own directives in subgraphs.
 * Type merging that can be relaxed even further with `@default` - [#1187](https://github.com/apollographql/federation/issues/1187)
 * Lots more!
