* 新功能： - 知识库管理界面支持查看、编辑、删除向量库文档。暂不支持增加（aggrid添加新行比较麻烦，需要另外实现） - 去除知识库管理界面中重建知识库和删除知识库按钮，建议用户到终端命令操作 修复： - 所有与知识库名称、文件名称有关的数据库操作函数都改成大小写不敏感，所有路径统一为 posix 风格，避免因路径文本不一致导致数据重复和操作失效 （close #2232） 开发者： - 添加 update_docs_by_id 函数与 API 接口。当前仅支持 FAISS，暂时未用到，未将来对知识库做更细致的修改做准备 - 统一 DocumentWithScore 与 DocumentWithVsId - FAISS 返回的 Document.metadata 中包含 ID， 方便后续查找比对 - /knowledge_base/search_docs 接口支持 file_name, metadata 参数，可以据此检索文档 * fix bug
