This update improves the import experience with a clearer interface, smarter file handling, saved field mappings, translated column matching, and new import templates across several business apps. It also fixes common import errors, such as empty files, localized yes/no values, and date handling, helping users bring data into Odoo with fewer failures and less manual setup.

Sales orders, quotes, and invoices now support clearer section headers and note lines directly in document lines, making long documents easier to organize and read. The related business-to-business display setting was moved into Accounting so invoicing users can benefit from it even without Sales, and a small list navigation crash was fixed.
