* Credo's warnings and errors have been resolved
* A lot of code repetition has been eliminated.
* Better validation of user provided options has been added to user facing API
  functions.
* Since the library employs behaviours to implement HTTP client adapters, the

* Due to changes listed above, the test suite coverage was greatly improved.
