If you look at the changes and cathegorize them they all fall in one if three camps:

- sugar for quality of life improvements that benefits everyone (like ? or NLL)

- new feature that lets you do something that couldn't be done before (like impl Trait or global allocators)

- new feature that removes a special case of the semantics that can be extrapolated from already present features (like associated consts and subslice patterns)
