Meridian v1.0.0

First public release of Meridian — a local-first markdown knowledge base for macOS, inspired by Obsidian (not a drop-in replacement).

Install (macOS)

1. Download Meridian-1.0.0-arm64.dmg (Apple Silicon) or Meridian-1.0.0.dmg (Intel).
2. Open the DMG, drag Meridian into Applications.
3. First launch: the DMG is unsigned. Right-click the app → Open → confirm once. Subsequent launches work normally.

Highlights

• CodeMirror 6 editor with split panes, tabs, slash commands, auto-save
• Wiki-links [[Note]], image embeds ![[photo.png]], note transclusion ![[Other Note]]
• Live Markdown preview (GFM tables, Mermaid, callouts, ==highlight==)
• Full-text search, Command Palette (⌘K), backlinks, tags, Table of Contents
• Graph view (D3) with timeline animation and WebM export
• Infinite Canvas (Konva) and Sketchpad (Excalidraw-like) — .canvas / .excalidraw files
• Daily notes (⌘D), templates with {{date}} / {{title}}
• HTML / PDF export
• Git panel: status, commit, push/pull, GitHub device-flow login, optional autocommit
• Plugin API v1 with hot-reload for community plugins under {vault}/.meridian/plugins/
• 8 themes, 5 accents, configurable editor fonts and layout

See CHANGELOG.md for the full feature list.

Notes

• macOS only for now. The app uses macOS-specific UI (hiddenInset titlebar, dock behavior). Windows/Linux builds are not supported in this release.
• Built unsigned. macOS Gatekeeper will block double-click on first launch — right-click → Open instead.
