Fix deserialization of run steps when using file search and mitigate .NET runtime issue when serializing ChatResponseFormat

CHANGELOG.md

@@ -12,9 +12,14 @@
 - Updated fine-tuning pagination methods `GetJobs`, `GetEvents`, and `GetJobCheckpoints` to return `IEnumerable<ClientResult>` instead of `ClientResult`. (commit_hash)
 - Updated the batching pagination method `GetBatches` to return `IEnumerable<ClientResult>` instead of `ClientResult`. (commit_hash)
 - Changed `GeneratedSpeechVoice` from an enum to an "extensible enum". (commit_hash)
+- Changed `GeneratedSpeechFormat` from an enum to an "extensible enum". (commit_hash)
+- Renamed `SpeechGenerationOptions`'s `Speed` property to `SpeedRatio`. (commit_hash)
 
 ### Bugs Fixed
 
+- Corrected an internal deserialization issue that caused recent updates to Assistants `file_search` to fail when streaming a run. Strongly typed support for `ranking_options` is not included but will arrive soon. (commit_hash)
+- Mitigated a .NET runtime issue that prevented `ChatResponseFormat` from serializing correct on targets including Unity. (commit_hash)
+
 ### Other Changes
 
 - Reverted the removal of the version path parameter "v1" from the default endpoint URL. (commit_hash)
