 # Release History
 
-## 2.0.0-beta.6 (Unreleased)
+## 2.0.0-beta.6 (2024-06-21)
+
+## Features Added
+
+- `OrganizationId` and `ProjectId` are now present on `OpenAIClientOptions`. When instantiating a client, providing an instance of `OpenAIClientOptions` with these properties set will cause the client to add the appropriate request headers for org/project, eliminating the need to manually configure the headers. ([9ee7dff](https://github.com/openai/openai-dotnet/commit/9ee7dff064a9412c069a793ff62096b8db4aa43d))
 
 ## Bugs Fixed
 
-- ([#72](https://github.com/openai/openai-dotnet/issues/72)) Fixed `filename` request encoding in operations using `multipart/form-data`, including `files` and `audio` (commit_hash)
-- ([#79](https://github.com/openai/openai-dotnet/issues/79)) Fixed hard-coded `user` role for caller-created Assistants API messages on threads (commit_hash)
-- Fixed non-streaming Assistants API run step details not reporting code interpreter logs when present

 ## Breaking Changes
 
 **Assistants (beta)**:
-- `AssistantClient.CreateMessage()` and the explicit constructor for `ThreadInitializationMessage` now require a `MessageRole` parameter. This properly enables the ability to create an Assistant message representing conversation history on a new thread.
