Version 3.16 just introduced some minor enhancements.
The selection of invoices to be displayed in the report-menu is fine granular. You could select for examples all invoices which are overdue. Go to the button in the left top corner of the list of reported items.
Invoices print additionial fields either in groups of 3 fields or line by line for one record. This is revereted from version 3.14 and 3.15. You can set you preference for each custom print-template.
