Best way to communicate changing the output of a module

[Stephen Patterson]

Hi All

I'm the maintainer of Finance::Bank::CooperativeUKPersonal, a module 
for downloading UK bank statements. Part of the output from this module 
is a statement date in dd/mm/yyyy (UK) format. As I've started using the 
module, I'm considering changing this to ISO-SQL standard - yyyy-mm-dd. 
What's the best way of communicating this change & managing things 
during changeover?
