-> 注意：
-> - 现在Flask最低版本要求提高到2.0
-> - 服务端可能不再完全支持低版本客户端
-> - 对3.12.6c版本，愚人节开关打开时点击`网络`按钮会闪退，原因不明
-> 
-> Note: 
-> - Now the version of Flask which is required should be up to 2.0.
-> - The server may no longer fully support lower version clients.
-> - For version 3.12.6c, when the switch of April Fool's Day is on, clicking the `Network` button will make the client break down. The reason is not clear now.
