## What’s New

- APIkit for REST now allows headers of type `array` to be accessed using small-case text style for
  header names to match the behavior of other header types.

- Request URI for REST now requires non-empty path parameters to ensure the necessary data is
  included in the API call.

- The APIkit router can now process payloads that have accented characters.
