2.15.1
Mustang 2.15.1 now also reads lineId and IncludedNotes on item- as well as InvoiceReferencedDocument and IncludedNotes, lineTotalAmount, TaxBasisAmount, duePayableAmount and prepaidamount on document level as well as classes like DirectDebit from both CII and UBL to/from JSON.
Error IDs are now logged in validation, fatal errors may no longer appear as warnings (#595) and various possible exceptions in the "metrics" action have been solved.
