This +should have minimal impact on the standard development workflow as both http://127.0.0.1:3000 +and http://localhost:3000 would continue to work as before on your own machine. + +However, with this change you would no longer be able to access the Rails server +from a different machine (e.g. your development environment is in a virtual +machine and you would like to access it from the host machine), you would need +to start the server with `rails server -b 0.0.0.0` to restore the old behavior. + +If you do this, be sure to configure your firewall properly such that only +trusted machines on your network can access your development server. + ### Production logging The default log level in the `production` environment is now `:debug`.
