+# Upcoming major 10.0 rease
+The DGS Framework was deeply integrated with Spring GraphQL earlier this year. 
+Details can be found [here](https://netflix.github.io/dgs/spring-graphql-integration).
+
+As announced previously, we will remove the "legacy" code (which doesn't leverage Spring GraphQL) by the end of 2024.
+Release 9.2.1 will likely be the final release before this happens.
+
+The next release will be 10.0, where all legacy code is removed.
+The existing starter will be updated to switch to the new behavior.
+For the majority of applications, this is an invisible change.
+At Netflix, we have completed migrating all our applications to the new implementation.
+Some issues were found and fixed on the way, but we see no blockers to proceed as planned.
+
+A [Pull Request](https://github.com/Netflix/dgs-framework/pull/1995) already includes most of the work to delete the legacy code.
+
+*Action: Please manually switch to the new `com.netflix.graphql.dgs:graphql-dgs-spring-graphql-starter` starter to ensure your app runs without problems so that you won't be surprised by the 10.0 version!*
