On Saturday, November 30th we released a new Mustangserver version which, simply put, supports more fields when reading and writing, incuding e.g. IncludedNotes. The difference between reading CII and UBL has been practically eradicated and e.g. prepaidamount is now supported. As usual, Mustangserver 1.5.1 is not yet the default version for all requests but can be specifically selected.
