Haystack 发布 v3.2.0-rc1：新增 Agent 压缩与 token 预算钩子

AI 摘要

Haystack 发布 v3.2.0-rc1，引入多项 Agent 与 Pipeline 相关更新。新功能包括实验性的 SummarizationCompactor（配合 CompactionHook 渐进式压缩对话以适配 token 预算）、TokenBudgetHook（限制 Agent 运行 token 消耗）、stop_run 控制标志，以及 Pipeline.add_components()、connect_many() 等便捷方法。升级注意事项涉及 OutputAdapter/ConditionalRouter 序列化需 unsafe=True 加载、Toolset 的 + 运算符被移除、tool_result_offloaded 元键改为列表等破坏性变更。
