Who upgraded from a commit BEFORE [d1d019383e5cb0c96ed2191f900970654e4055c0](https://github.com/syzoj/syzoj/commit/d1d019383e5cb0c96ed2191f900970654e4055c0) (Mar 30, 2019) **MUST** upgrade web server's Redis to at least version 5, and fill web config's `judge_token` with random key. Judge server must be upgraded together, and `daemon-config.json`'s `ServerUrl` and `ServerToken` (= `judge_token`) must be filled. If judge and web run on different server, it's recommend to move RabbitMQ to judge server.
