+- Added `MessageId` to `ChatMessage` and `ChatResponseUpdate`.
+- Added `AIFunctionArguments`, changing `AIFunction.InvokeAsync` to accept one and to return a `ValueTask`.
+- Updated `AIJsonUtilities`'s schema generation to not use `default` when `RequireAllProperties` is set to `true`.
+- Added `ISpeechToTextClient` and supporting types.
+- Fixed several issues related to Native AOT support.
+
 ## 9.3.0-preview.1.25161.3
 
 - Changed `IChatClient.GetResponseAsync` and `IChatClient.GetStreamingResponseAsync` to accept an `IEnumerable<ChatMessage>` rather than an `IList<ChatMessage>`. It is no longer mutated by implementations.

 # Release History
 
+## 9.4.0-preview.1.25207.5
+
+- Updated `GetResponseAsync<T>` to default to using JSON-schema based structured output by default.
+- Updated `AIFunctionFactory` with support for customizable marshaling of function parameters and return values.
+- Updated `AIFunctionFactory` with a new `Create` overload that supports creating a new receiver instance on each invocation, with either Activator.CreateInstance or ActivatorUtilities.CreateInstance.
+- Updated `AIFunctionFactory` to support injecting an `IServiceProvider` as an argument, sourced from the `AIFunctionArguments` passed to `AIFunction.InvokeAsync`.
+- Simplified `FunctionInvokingChatClient` error handling, removing `RetryOnError` and replacing it with `MaximumConsecutiveErrorsPerRequest`.
+- `FunctionInvokingChatClient` will now ensure that it invokes `AIFunction`s in the same `SynchronizationContext` that `GetResponseAsync`/`GetStreamingResponseAsync` was called in.
+- `OpenTelemetryChatClient` now considers `AdditionalProperties` to be sensitive and will only use that data as tags when `EnableSensitiveData` is set to `true`.
+- Updated `OpenTelemetryChatClient`/`OpenTelemetryEmbeddingGenerator` to conform to the latest 1.32 draft specification of the Semantic Conventions for Generative AI systems.
+- Updated the key used by `DistributedCachingChatClient` to employ SHA384 instead of SHA256.
+- Lowered `System.Text.Json` 9.x dependency to 8.x when targeting `net8.0` or older.
+ 
 ## 9.3.0-preview.1.25161.3
 
 - Added caching to `AIFunctionFactory.Create` to improve performance of creating the same functions repeatedly. As part of this, `AIJsonSchemaCreateOptions` now implements `IEquatable<AIJsonSchemaCreateOptions>`.
