The incremental delivery portion of the GraphQL specification has been unchanged since 2023 and will be merged into the draft specification soon. Currently, Apollo Kotlin supports the`@defer` directive using an older (but still functional) implementation of the incremental delivery protocol. Soon, we will release support for the current version of the protocol, along with support for the`@stream` directive for streaming elements in lists. We will also keep supporting the old format as well. For more information, see the RFC here:https://github.com/graphql/graphql-spec/pull/1110

[Jetpack Compose](https://developer.android.com/jetpack/compose) is a declarative UI framework for building Android UIs written in Kotlin.We[are](https://github.com/apollographql/apollo-kotlin-compose)[experimenting](https://github.com/apollographql/apollo-kotlin-compiler-plugin) with a few different approachesforsupportingComposeinthe Apollo Kotlin library.Our 3.8.0 release introduced an experimental API for use with Compose but gathered little feedback. We're planning to revisit this with more ambitious goals in terms of fragments colocation, error boundaries and more generally integration with the UI framework.

This pattern is encouraged by[Relay](https://relay.dev/docs/tutorial/fragments-1/) and[Apollo Client (TypeScript)](https://www.apollographql.com/blog/optimizing-data-fetching-with-apollo-client-leveraging-usefragment-and-colocated-fragments) and may prove to be valuable to developers using Compose.
