Mustangserver is the REST API which provides functionality from the Mustangproject library, which it is based on, and more. Since Mustangproject has been upgraded to 2.13 in the background, some fixes, like an improved conversion of UBL to HTML, or the removal of due date as de facto required field, are now also taking affect, additionally to the fixes immediately applied to Mustangserver: two fixes concerning article description as well as an improved manual, which now also features instructions how to use Mustangserver in conjunction with C#.
