I've heard that Amazon does multiple releases every day during the course of a Sprint. I am aware that we can release any time during the Sprint. I am assuming that when mid sprint releases happen, then it is also reviewed kinda like a mini Sprint Review.
So, at the end of the Sprint, do we still need a Sprint Review? What would we be reviewing at this meeting, the Increment of all that was released during the Sprint? Is it right to say that what was released mid sprint is also an Increment?
