-This release renames the Model Gateway chat types, moves `EmptyChatResponseException` into a dedicated package, introduces `ModerationException` for responses blocked by the moderation system, makes every collection the SDK exposes unmodifiable, and adds `DeveloperMessage`, `PartialResponseInterceptor`, and streaming support for `MessageInterceptor`.
+This release renames the Model Gateway chat types, moves `EmptyChatResponseException` into a dedicated package, introduces `ModerationException` for responses blocked by the moderation system, makes every collection the SDK exposes unmodifiable, adds `DeveloperMessage`, `PartialResponseInterceptor`, and streaming support for `MessageInterceptor`, and ships GraalVM native image reachability metadata for both modules.
 
 ---
 
 ## What's new
 
+### GraalVM native image support
+
+Both `watsonx-ai-core` and `watsonx-ai` ship GraalVM reachability metadata under `META-INF/native-image/`. No extra configuration is required: add the SDK to a native-image project and the reflection, proxy, and resource entries are picked up automatically.
+
+---
+
 ### `DeveloperMessage`
 
 `DeveloperMessage` is a new `ChatMessage` subtype that carries the OpenAI `developer` role. Newer models use it in place of `SystemMessage` to set the assistant's behavior. It is accepted only by the Model Gateway chat APIs (`ModelGatewayChatService` and `ModelGatewayTextChatRequest`).
