Laravel Upgrade Guide

Upgrading From 4.0 to 4.1

• Update composer.json to require "laravel/framework": "4.1.*"
• Remove call to redirectIfTrailingSlash in /bootstrap/start.php file.
• Replace /public/index.php with this file, and /artisan with this file.
• Add new app/config/remote.php file from here
• Add new expire_on_close and secure options to session configuration file to match this file.
• Add new failed queue job option to queue configuration file to match this file.
• Edit app/config/database.php and update redis.cluster option to false to turn Redis clustering off by default.
• Edit app/config/view.php and update pagination option to use bootstrap 3 as default pagination view (optional).
• Edit app/config/app.php so the aliases and providers array match this file:
  • in aliases change 'Controller' => 'Illuminate\Routing\Controllers\Controller', to use Illuminate\Routing\Controller.
  • in providers add 'Illuminate\Remote\RemoteServiceProvider',.
  • in aliases add 'SSH' => 'Illuminate\Support\Facades\SSH',.
• If app/controllers/BaseController.php has a use statement at the top, change use Illuminate\Routing\Controllers\Controller; to use Illuminate\Routing\Controller;. You may also remove this use statament, for you have registered a class alias for this.
• If you are overriding missingMethod in your controllers, add $method as the first parameter.
• Password reminder system tweaked for greater developer freedom. Inspect stub controller by running auth:reminders-controller Artisan command.
• Update reminders.php language file to match this file.
• If you are using http hosts to set the $env variable in bootstrap/start.php, these should be changed to machine names (as returned by PHP's gethostname() function).
