Full Release Notes
修复 Eino 单代理模式下长对话触发摘要压缩后，tool_call/tool_result 配对被破坏导致模型 API 返回 400 错误（NodeRunError）的问题。为 agentic 路径补充了与 classic 路径对齐的 toolPairReconciler 和 orphanToolPruner 纵深防御中间件。 --- Fixed a bug where long conversations in Eino single-agent mode could trigger a 400 error (NodeRunError: "insufficient tool messages following tool_calls message") after summarization truncated the message history and broke tool_call/tool_result pairing.
