+  should you run into any problems. You may wish to review
+  [the pull request](https://github.com/jeregrine/jsonapi/pull/189) for more details.
+- [More typespecs](https://github.com/jeregrine/jsonapi/pull/198)
 - `EnsureSpec` Plug now sets the JSON:API response content type
   [for you](https://github.com/jeregrine/jsonapi/pull/185). This means you need
   not manually include the `ResponseContentType` Plug in your pipeline should you
   already have `EnsureSpec` in play. Please see the documentation for
   `ResponseContentType` should you wish to override it for a specific end-point.
 
+### Changed

+- Documentation improvements
