What’s new

Bug Fixes
- Closing the line item editor without saving could leave the subtotal and total out of date.
- Totals are recalculated with your current rounding when a document is opened or a PDF is created, so they always match the line items.
- Combined invoices carry over discounts per tax rate.
- Unsaved edits to items, business info or bank accounts are no longer kept.
- Receipts: the "For:" line no longer overlaps the totals.

Improvements
- Document Settings save instantly.
