从 ConversationSummaryMemory 或 ConversationSummaryBufferMemory 迁移

如果你试图从下面列出的旧记忆类中迁移出去，请按照本指南操作：

记忆类型	描述
ConversationSummaryMemory	Continually summarizes the conversation history. The summary is updated after each conversation turn. The abstraction returns the summary of the conversation history.
ConversationSummaryBufferMemory	Provides a running summary of the conversation together with the most recent messages in the conversation under the constraint that the total number of tokens in the conversation does not exceed a certain limit.

请按照以下 关于LangGraph汇总的指南 操作。

本指南展示了如何在丢弃较早消息的同时保持对话的持续摘要，从而确保这些消息在后续轮次中不会被重新处理。
