This update addresses a significant change in the format required for Spanish VAT reports (Mod303) for the year 2026. The update includes a new field for petrol data and adjustments to the report's structure. This ensures continued compliance with Spanish tax regulations.

The format for 2026 changed quite significantly.

There is an extra field for the petrol, which we
basically do not touch and a lot of casillas
that changed places.
