In the previous version the processing of asynchronous MDN led to the error „Object reference not set to an instance of an object.“. This error has been fixed. The unit test for processing the asynchronous MDN contained a gap, so that this error was not covered in the release and on our in-house system the error did not occur because the „Request bundling“ flag is set there for the PortEventListener . For both cases, for with „request bundling“ and without „request bundling“ the unit tests were adjusted.

Updating the sFtp and Ftp client channels to the current state, among other things to match the current sFtp certificate handling.
