## Version history (last 5 releases)

### 1.16.1 — 2026-09-19

Bug Fixes
- Fixed a rounding error that could make the tax amount and the total off by one when a discount was applied.
- The per-rate tax breakdown and the summary now always show the same tax amount.
- Fixed the client's department and contact name missing from the PDF templates.
- Fixed a duplicate sample client being created on first launch.

### 1.16.0 — 2026-09-16

New Features & Improvements
- Modernized UI design with enhanced aesthetics and clarity.
- Improved layout and interaction across document lists, edit screens, and onboarding.
- Performance improvements and bug fixes.

### 1.15.1 — 2026-09-04

Fixes
- When a document preview could not be generated, the app showed a blank grey area. It now explains what went wrong and offers a Retry button.
- Improved diagnostics for preview failures, so reported problems are easier for us to track down.

### 1.15.0 — 2026-09-03

A brand-new look
- Every screen has been redesigned. Translucent materials and a reworked information hierarchy make your document, client and item lists readable at a glance.
- Dark mode has been rebuilt. Amounts and status badges were recolored so they stay legible against a dark background.
- List rows now adapt to the window width. On desktop, narrowing the window never drops the amount or the status, and the client name stays readable.

New: Pick your theme color
- Settings > Theme color lets you choose the app's accent from seven colors: Blue, Green, Sky, Emerald, Teal, Indigo and Graphite.
- Light mode and dark mode can be set independently.
- This is separate from the brand color used in your PDFs, so your documents look exactly as before.

Fixes
- Fixed being unable to add a line item from the item list.

### 1.14.0 — 2026-09-01

New: Default due dates per document type
- You can now set a default deadline for each document type. It appears as "Valid until" on estimates, "Due date" on invoices, and "Requested delivery date" on purchase orders.
- Choose end of current month, end of next month, a number of days after the issue date, or no due date at all - so month-end billing terms work out of the box.
- Previously this setting lived deep inside Business info > Bank account and only affected invoices. It now lives in Settings > Document settings > Default due dates. Your existing setting is carried over unchanged.
- Purchase order PDFs now print the requested delivery date.
- Receipts and delivery notes no longer show a due date field, since they have no deadline.

Improvements
- The dedicated receipt layout now supports dual-currency and bilingual display. Previously it rendered in the primary currency and language even when those options were enabled.

Fixes
- Fixed documents getting mixed up, or the screen turning blank, when two different document types were open in separate tabs on desktop.
- Fixed deleted business profiles still being referenced by existing documents.
