I know that in Yii 1.x you could create a component that would extend either CComponent or CApplicationComponent. One of which would create a new instance each time a new object was created but the other would keep alive the same instance.
In Yii2 I can only find that I can extend \Yii\base\Component which keeps the first instance for any future calls. What do I need to do that would create a fresh instance each time a try to create a new instance?
