v4.1.1

What's New

"None" Reasoning Effort Support

GPT-5.2 and GPT-5.1 general purpose models now support reasoning_effort: "none" which disables the reasoning phase entirely. This can result in faster responses when reasoning is not needed.

• gpt-5.2-none - GPT-5.2 with reasoning disabled
• gpt-5.1-none - GPT-5.1 with reasoning disabled

Note: Codex variants do NOT support "none" - it auto-converts to "low" for Codex/Codex Max, or "medium" for Codex Mini.

Bug Fixes

• Fixed orphaned function_call_output 400 errors - Previously, when conversation history contained item_reference pointing to stored function calls, orphaned function_call_output items could cause API errors. Now handles orphans regardless of tools presence and converts them to assistant messages to preserve context while avoiding errors.

• Fixed OAuth HTML version display - Updated the version shown in the OAuth success page from 1.0.4 to 4.1.0.
