Hi All!
MLInvoice 1.20.0 has been released. This release includes a lot of new features and fixes. See https://www.labs.fi/mlinvoice_features.eng.php#changelog for full changelog. Installation package and instructions are available at https://www.labs.fi/mlinvoice_installation.eng.php, but automatic update directly from MLInvoice is the easiest method.
Regards,
Ere
And right away there's version 1.20.1 to fix sending via Postita.fi. Sorry for the inconvenience!
