# v0.7.1 Release Notes

> v0.7.0 -> v0.7.1

## Summary

Stops Claude from rejecting conversations that replay argument-less tool calls, which previously broke multi-turn tool use and cross-provider fallback. Documentation catches up with OpenRouter's multimodal support and per-provider model filtering.

修正 Claude 在重送無參數工具呼叫的對話時拒絕請求的問題，此問題先前會中斷多輪工具呼叫與跨供應商 fallback。文件同步補上 OpenRouter 多模態支援與各供應商模型篩選說明。
