CHANGELOG.md

 ## [0.11.0] - 2018-04-15
 And v0.11.0 finally comes along! This release has been in the works for almost four months now, with an alpha and beta helping square away the issues.
 
-We're adding a lot of features to improve debugging, better support international users, and make things better for network administrators. Among the new features, you can use the `LANGUAGE` command to set a custom server language (see our [CrowdIn](https://crowdin.com/project/oragono) to contribute), expose a debugging `pprof` endpoint, reserve nicknames with `NickServ`, and force email verification for new user accounts. On the improvements side we have a `CAP REQ` fix, and we now have a manual that contains a nice overview of Oragono's documentation.

 The above will change the server language to Romanian, with a fallback to Chinese. English will always be the final fallback, if there's a line that is not translated. Substitute any of the other language codes in to select other languages, and run `/LANGUAGE en` to get back to standard English.
 
-Our language and translation functionality is very early, so feel free to let us know if there are any troubles with it! If you know another language and you'd like to contribute, we've got a CrowdIn project here: [https://crowdin.com/project/oragono](https://crowdin.com/project/oragono)
