At the moment if you use %m+1 %y to substitute dates into invoices, an invoice generated in Dec 2015 would display "January 2015" rather than the intended "January 2016". Something needs to be added to check if %m+1 takes you into a new year.
This could be done by having other subsitutions for 'year of next month' or 'year of last month' as well rather than %y having to try to guess what the user meant.
