1.5.0 1.5.0
===== =====
<date> 2017-11-30
Now using factory. Export is now also possible on OutputStream.
Further dev improvements: no more need to call PDFattachZugferdFile(null) or exporter close();
toecount now has options to combine documents and upgrade xml file from ZF1 to ZF2
More unit tests, e.g. for custom xml export, PDF/A Schema extensions.
Toecount is now integrated and the main class so "java -jar mustang-1.5.0.jar" should suffice
Support for ZUGFeRD 2.0 "public review" part 1.
Now using factories to create/configure ZUGFeRDExporter.
Export is now also possible on OutputStream.
Removed need to call PDFattachZugferdFile(null) or exporter close();
More unit tests, e.g. for custom xml export, PDF/A Schema extensions.
The command line utility "toecount" is now integrated and the main class so "java -jar mustang-1.5.0.jar" should suffice.
It now also features options to combine PDF with XML and upgrade XML files from ZF1 to ZF2.
First attempts be able to start with a PDF/A-3 in the first place and better error messages for non-PDF/A-conformance.
Further changes: Further changes:
be able to specify profile #50 * be able to specify profile #50
close pdf files automatically after export #49 * close pdf files automatically after export #49
ZUGFeRDimporter does not close #48 * ZUGFeRDimporter does not close #48
command line option -e does not work on all-in-one jar #47 * command line option -e does not work on all-in-one jar #47
invoices have wrong namespaces #45 * invoices have wrong namespaces #45
invalid a3 #44 * invalid a3 #44
warn on export #39 * warn on export #39
