I would suggest to, at least, write a notation about `eprintln!` and for those who are behind can still read about the `writeln!` option. I'm not sure if a bigger revision than this suggestion is worthwhile.\r\n\r\n[1]: https://blog.rust-lang.org/2017/07/20/Rust-1.19.html \"Rust 1.19 – What's new\""},"comment":{"url":"https://api.github.com/repos/rust-lang/book/issues/comments/317459074","html_url":"https://github.com/rust-lang/book/issues/840#issuecomment-317459074","issue_url":"https://api.github.com/repos/rust-lang/book/issues/840","id":317459074,"user":{"login":"steveklabnik","id":27786,"avatar_url":"https://avatars2.githubusercontent.com/u/27786?v=4","gravatar_id":"","url":"https://api.github.com/users/steveklabnik","html_url":"https://github.com/steveklabnik","followers_url":"https://api.github.com/users/steveklabnik/followers","following_url":"https://api.github.com/users/steveklabnik/following{/other_user}","gists_url":"https://api.github.com/users/steveklabnik/gists{/gist_id}","starred_url":"https://api.github.com/users/steveklabnik/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/steveklabnik/subscriptions","organizations_url":"https://api.github.com/users/steveklabnik/orgs","repos_url":"https://api.github.com/users/steveklabnik/repos","events_url":"https://api.github.com/users/steveklabnik/events{/privacy}","received_events_url":"https://api.github.com/users/steveklabnik/received_events","type":"User","site_admin":false},"created_at":"2017-07-24T15:25:17Z","updated_at":"2017-07-24T15:25:17Z","body":"Yup, it's fixed in beta: https://doc.rust-lang.org/beta/book/second-edition/ch12-06-writing-to-stderr-instead-of-stdout.html\r\n\r\nThanks for the report!
