Apollo Federation 1.0 supergraphs will no longer be supported with the release of Apollo Router versions 1.60 and beyond, due to the introduction of a new native query planner that offers significant performance enhancements. This upgrade is essential for leveraging these improvements fully and comes as part of the transition from Federation 1.0 to Federation 2.0, which simplifies maintenance and enhances security by eliminating dependencies. The migration process focuses on the composition layer and can be completed with minimal changes, with support available through Apollo's resources and ongoing commitment to transparent communication and improving deprecation processes.
