重要提示

Langchain-Chatchat v0.2.9 版本中修改了configs中配置项，建议所有用户按照 Wiki 的开发部署中的相关描述重新完成项目中的配置文件生成。开发部署过程遇到问题请先到 Github Wiki / issues 中搜索。

此外，v0.2.9 版本中知识库相关信息的数据库表发生了变化，如果继续使用之前版本的配置，可使用 python init_database.py --create-tables 仅更新数据库表，不重建知识库。

本次更新中依赖 Python 包与其版本发生了大量更新，请使用pip install -r requirements.txt进行更新。
