I'm really excited about the Scoped Slots feature. Finally it's really easy to create components that can be customized by the user from the outside. For example, it's now really easy to create a data table (with features like filters and sort), and with each row showing not only the data text, but also any other feature you might want to embed in it.
I believe there was a way (probably a complicated hacky way) to achieve this previously too, but I never investigated it too much. Now it's really easy.
Kudos to the Vue team for this release!
