* remove outdated docs sections
* Add what's new section

This PR changes behavior of parameters that are typed in a union with `None`. Prior behavior was to implicitly default their value to `None` if a value wasn't provided making an apparently non-optional parameter (i.e., no declared default) actually optional. Surprising behavior at best, dangerous at worst.

New behavior is to throw a client error when a parameter without a default is not provided.

* refactor: removes deprecated OpenAPIController

This PR removes all deprecated elements of OpenAPIConfig and the OpenAPIController, removes any obsolete tests and refactors tests that were parametrized to test both OpenAPIController and the router-based approach.
