+- Added `ReasoningOptions` to `ChatOptions` for configuring reasoning effort and output.
 - Unsealed `FunctionCallContent` and `FunctionResultContent`.
 - Added `InformationalOnly` property to `FunctionCallContent` to indicate whether the content is informing the consumer about a call that's being made elsewhere or that is a request for the call to be performed.
 - Added `LoadFromAsync` and `SaveToAsync` helper methods to `DataContent` for file I/O operations.
+- Removed `[Experimental]` attribute from `IChatReducer`.
 - Fixed JSON schema generation for nullable reference type annotations on parameters in AIFunctions.
+- Fixed `DataUriParser` to default to `text/plain;charset=US-ASCII` per RFC 2397.
+- Fixed serialization handling of `ImageGenerationToolCallContent` and `ImageGenerationToolResultContent`.

 # Microsoft.Extensions.AI.OpenAI Release History
 
-## NOT YET RELEASED
+## 10.3.0
 
+- Marked Microsoft.Extensions.AI.OpenAI as stable. Portions of the surface area are still marked as [Experimental], e.g. because the OpenAI Responses surface area from the OpenAI library is [Experimental], the corresponding `AsIChatClient` in Microsoft.Extensions.AI.OpenAI is as well.
+- Added support for `ReasoningOptions` in `ChatOptions` via the OpenAI chat clients.
+- Updated the OpenAI Responses `IChatClient` to handle streaming code interpreter content.
+- Fixed the OpenAI Responses `IChatClient` to preserve encrypted reasoning content during streaming.
 - Fixed tool call descriptions to not drop extraneous JSON properties.
 - Updated to accommodate the additions in `Microsoft.Extensions.AI.Abstractions`.
