# Changelog

> What changed in each Mernyx release: the canvas, the source editor, AI generation and fix, exports, and the update channel.

Every Mernyx release, newest first.

Mernyx checks for updates once a day and asks before it installs anything. Every release is signed and notarised.

## 1.0.0

October 22, 2026

The first public release. Everything below arrived in it.

### Added

- **Interactive canvas** — Add, move, connect and restyle nodes on a real vector canvas. What the canvas writes is standard Mermaid — not a sidecar file.
- **A source editor that knows the syntax** — Per-family keyword highlighting, and diagnostics that mark the exact range of a mistake.
- **Two-way sync** — Edit the text and the canvas recompiles; move a node and the source follows. Three panes, one document.
- **A properties inspector** — Fill, stroke, text colour, width and opacity become ordinary style rules — and the inspector says where the style came from.
- **34 diagram families** — Each with its own layout, its own editing rules and a starter template.
- **Export to PNG, SVG and PDF** — All three come from the same scene the canvas draws, so the file matches what you saw.
- **AI generation and fix, with your own key** — Describe a diagram, or hand it one that will not compile. The model writes Mermaid; your own endpoint and key do the talking.
- **A template library** — A starter diagram for every family, with search, a thumbnail and the source to read.
- **Quick Look and Finder thumbnails** — Preview a .mmd or .mermaid file in place, without launching the app.
- **Format Document** — ⌥⌘I tidies whitespace and flowchart indentation without touching your comments or statement order.
