 # Unreleased
+* [changed] **Renamed / Replaced:** Vertex AI in Firebase (`FirebaseVertexAI`) has been renamed and
+ replaced by the new Firebase AI SDK: `FirebaseAI`. This is to accommodate the evolving set of
+ supported features and services. Please migrate to the new `FirebaseAI` package. See details in the
+ [migration guide](/docs/vertex-ai/migrate-to-latest-sdk).
+
+ Note: Existing Vertex AI in Firebase users may continue to use the SDK and receive bug fixes but,
+ going forward, new features will only be added into the new Firebase AI SDK.
+* [changed] **Breaking Change**: Removed the `LiveContentResponse.Status` class, and instead have nested the status
+  fields as properties of `LiveContentResponse`. (#6941)
+* [changed] **Breaking Change**: Removed the `LiveContentResponse` class, and instead have provided subclasses
+  of `LiveServerMessage` that match the responses from the model. (#6941)
+* [feature] Added support for the `id` field on `FunctionResponsePart` and `FunctionCallPart`. (#6941)
+* [feature] Added a helper field for getting all the `InlineDataPart` from a `GenerateContentResponse`. (#6941)
