-* [GraphOS](https://www.apollographql.com/docs/graphos) – A free, end-to-end platform for managing your GraphQL lifecycle. Track your GraphQL schemas in a hosted registry to create a source of truth for everything in your graph. GraphOS provides an IDE (Apollo Explorer) so you can explore data, collaborate on queries, observe usage, and safely make schema changes.

 # CHANGELOG for `@apollo/composition`
 
+## 2.8.4

+
+- Add a fast path to skip override validation for fields without any subgraph `@override`s. ([#3070](https://github.com/apollographql/federation/pull/3070))
+
+- Type merging now uses maps instead of sparsely-populated arrays for per-subgraph data. ([#3069](https://github.com/apollographql/federation/pull/3069))

+- Stop duplicating hints for inconsistent value type fields per subgraph. ([#3071](https://github.com/apollographql/federation/pull/3071))
+
+- Fix logic to compute missing subgraphs when generating composition hints/errors ([#3076](https://github.com/apollographql/federation/pull/3076))
