• Announce LTS.
• PHP 7 strict scalar types everywhere.
• Decouple routing from controllers and modules. Allow specifying any class method as a callback for a matching route.
• Merge components and DI container configs.
• Try to eliminate Object and Component turning these into traits. Could extract AccessorTrait, EventTrait etc. Alternatively we can drop accessors. Will get PSR-2 and stricter interfaces in exchange additionally to possibility to get more performance.
• When triggering events, pass data as a separate argument instead of a part of event object (commonly referred to as inconvenient).
• Move methods from Yii class into helpers. For example, Yii::getAlias() could be FileHelper::getAlias().
