 # Release History
 
+## 9.0.1-preview.1.24570.5
+
+- Moved the `AddChatClient`, `AddKeyedChatClient`, `AddEmbeddingGenerator`, and `AddKeyedEmbeddingGenerator` extension methods to the `Microsoft.Extensions.DependencyInjection` namespace, changed them to register singleton instances instead of scoped instances, and changed them to support lambda-less chaining.
+- Renamed `UseChatOptions`/`UseEmbeddingOptions` to `ConfigureOptions`, and changed the behavior to always invoke the delegate with a safely-mutable instance, either a new instance if the caller provided null, or a clone of the provided instance.
+- Renamed the final `Use` method for building a builder to be named `Build`. The inner client instance is passed to the constructor and the `IServiceProvider` is optionally passed to the `Build` method.
+- Added `AsBuilder` extension methods to `IChatClient`/`IEmbeddingGenerator` to create builders from the instances.
+- Changed the `CachingChatClient`/`CachingEmbeddingGenerator`.`GetCacheKey` method to accept a `params ReadOnlySpan<object?>`, included the `ChatOptions`/`EmbeddingGeneratorOptions` as part of the caching key, and reduced memory allocation.
+- Added support for anonymous delegating `IChatClient`/`IEmbeddingGenerator` implementations, with `Use` methods on `ChatClientBuilder`/`EmbeddingGeneratorBuilder` that enable the implementations of the core methods to be supplied as lambdas.
+- Changed `UseLogging` to accept an `ILoggerFactory` rather than `ILogger`.
+- Reversed the order of the `IChatClient`/`IEmbeddingGenerator` and `IServiceProvider` arguments to used by one of the `Use` overloads.
+- Added logging capabilities to `FunctionInvokingChatClient`. `UseFunctionInvocation` now accepts an optional `ILoggerFactory`.
+- Fixed the `FunctionInvokingChatClient` to include usage data for non-streaming completions in the augmented history.
+- Fixed the `FunctionInvokingChatClient` streaming support to appropriately fail for multi-choice completions.
+- Fixed the `FunctionInvokingChatClient` to stop yielding function calling content that was already being handled.
+- Improved the documentation.
+
 ## 9.0.0-preview.9.24556.5
 
 - Added `UseEmbeddingGenerationOptions` and corresponding `ConfigureOptionsEmbeddingGenerator`.
