+### Changed

+- Kiota-Java has moved away from Async/Completable futures, thus Async components are no longer utilized and have been removed. Furthermore, requestAdapter methods no longer use the async suffix. [#175](https://github.com/microsoft/kiota-java/issues/175)
+- ApiException class now extends RuntimeException instead of Exception.
