Nuance to know for client follow-ups in v18

Since version 18, all open invoices (whether overdue or not) are sent to customers. Odoo no longer allows you to exclude certain invoices from the reminder as in version 17. This option has been removed because Odoo considers that when a reminder letter is sent, the aim is to get paid, whether the invoices are overdue or not. However, at the time of sending, you still have the option of manually deleting overdue invoice documents from the dunning e-mail attachments. This will not remove these invoices from the dunning letter.
