I am making some modifications for a migration from Odoo 14 to 17 but in the odoo 14 code there are some model fields that have the filters parameter, for example:

file = fields.Binary('File', filters='.xls')

but I don't understand what that code does since in 17 it returns warnings for that parameter,

does this do anything??? And in case it works for me, how can I use it in version 17???
