Prompt Optimizer v2.11.6

Summary

• Updates the built-in MiniMax text provider lineup so MiniMax-M3 is the default while MiniMax-M2.7 variants remain selectable.
• Fixes OpenAI large image-model calls by avoiding the unsupported response_format parameter when the selected model does not support it.
• Allows Unicode variable names in the variable manager/editor, including Chinese variable identifiers.
• Improves provider/evaluation error formatting so detailed API errors are easier to read and diagnose.

Highlights

• Model and prompt workflows are a little more forgiving: newer MiniMax defaults are available immediately, non-English variable names work in the manager, and provider failures surface clearer details.

Product Updates

Desktop

• Desktop version metadata is synchronized to v2.11.6 and inherits the shared MiniMax, image-provider, variable-manager, and error-formatting fixes.

Web

• MiniMax-M3 is now the default MiniMax text model, with MiniMax-M2.7 and MiniMax-M2.7-highspeed still available as alternatives.
• Variable management now accepts Unicode names consistently across the editor and manager modal.
• Provider/evaluation error messages now preserve and format structured detail so users can see the actionable API failure instead of a flattened generic message.

Extension

• Extension version metadata is synchronized to v2.11.6 and inherits the shared provider and variable-handling updates.

Core/Infra

• Removed deprecated MiniMax-M2.5 variants from the built-in MiniMax model list and updated adapter tests for the new lineup.
• Updated OpenAI image adapter parameter handling and regression coverage for large image models that reject response_format.
• Added regression coverage for Unicode variable names and formatted provider error details.

Fixes

• Fixed OpenAI large image-model requests failing with Unknown parameter: 'response_format'.

• Fixed provider/evaluation error details being hard to inspect after API failures.
