What's new in v1.0.5

Features

• Obsidian wiki links: [[Page Name]] links render and navigate correctly via a marked.js extension
• Agent-native control: Unix socket IPC for programmatic control from Claude Code, CLI tools, and scripts
• Crash diagnostics: Rich crash dialog with native crash dumps and dead-renderer guards
• Dev/release badge: UI clearly distinguishes dev builds from production releases
• Install shortcuts: npm run install-dev (fast local build) and npm run install-prod (download latest release)

Fixes

• Exit edit mode on Escape key press
• Sidebar label overflow clamping (long filenames no longer bleed past sidebar edge)
• Homepage and landing page concepts added

Infrastructure

• Build channel system (OMR_BUILD_CHANNEL=dev|release) for clear build provenance
• Atomic install-dev.sh with staging-then-swap pattern (Codex-reviewed)
• MAS TestFlight v1.0.5 build submitted (waiting for external review)

Full changelog

103 commits since v1.0.4. See commit history for details.

Development preview — not the latest stable. Use v1.0.4 for production.

Second dev preview on top of v1.0.5-dev1, adding two big improvements.

What's new since v1.0.5-dev1

🔥 Editor-per-tab refactor — undo history is no longer wiped (a4h)

The biggest of the three undo-loss bugs is fixed: switching tabs and toggling preview no longer destroys browser undo history.

Each tab now owns its own textarea (and EasyMDE/CodeMirror instance for rich mode), kept alive across tab switches and preview toggles. Editing in tab A, switching to tab B, switching back to tab A, hitting Cmd+Z now steps back through your edits in tab A.

The smaller within-tab rich/plain toggle case still loses undo on the OLD mode — tracked as a P3 follow-up.

📂 Open folder as project (7qf)

Two new ways to open a folder as the workspace of a fresh window:

1. Right-click any folder in the sidebar → "Open in New Window"
2. Cmd+P now matches folder names — folder results show a 'Folder' badge + 📂 icon and open in a new window when selected

For agents/scripts: omr --cmd open /path/to/folder --new-window

This lets you treat OpenMarkdownReader more like VS Code — keeping multiple project workspaces open in separate windows without disturbing each other.

Carrying forward from v1.0.5-dev1

• Agent-native control via Unix socket (26+ commands via omr --cmd)
• Per-build incrementing build numbers (this is build 141, next will be 142+)
• Visible build pill in title bar on packaged installs
• Wikilink resolver, Cmd+P tilde expansion, sidebar collapse-all
• Electron 41.0.2 (fixes macOS Tahoe 26.3 EXC_BREAKPOINT)

Install

```bash
hdiutil attach OpenMarkdownReader-1.0.5-universal.dmg
ditto /Volumes/OpenMarkdownReader/OpenMarkdownReader.app /Applications/OpenMarkdownReader.app
hdiutil detach /Volumes/OpenMarkdownReader
```

Universal binary, notarized.

For contributors

See `docs/CONTRIBUTOR-ONBOARDING.md` and `docs/HANDOFF-LIST.md`. The handoff list is updated to reflect that a4h and 7qf are no longer blocking — r1r (Milkdown WYSIWYG) and kq3 (Escape to exit edit) are now unblocked and ready to discuss.

Development preview — not the latest stable. Use v1.0.4 for production.

This release packages everything on feature/daily-notes since v1.0.4 (Mar 2026):

What's new

Agent-native control (Unix socket + CLI)

• New omr --cmd <command> interface — drive the running app from any script or AI agent
• 26 commands: get-state, list-tabs, open, save, switch-tab, set theme, search, export-pdf, etc.
• Unix socket at `~/Library/Application Support/OpenMarkdownReader/omr.sock`
• Event stream via `omr --cmd watch` (NDJSON)
• Every future feature must ship with a CLI command — see REQUIREMENTS.md

Bug fixes

• Wikilink `[[...]]` now resolves on first paint (was racing the index build)
• Cmd+P paths support `~/...` expansion to your home directory
• Chat-view code fences no longer get inline-code corrupted by backticks inside them
• Added Collapse All button to the sidebar tree

Build / dev experience

• Per-build incrementing build numbers — two builds of the same commit now have distinct numbers (max(gitCount, prev+1))
• Visible build number in titlebar — packaged installs show `b` as a subtle pill, no more guessing which v1.0.4 you're on
• Faster dev iteration loop (file-watcher → soft reload, restart only when main process changes)
• Electron upgraded 40.1.0 → 41.0.2 (fixes EXC_BREAKPOINT crash on macOS Tahoe 26.3)

MAS / TestFlight

• Build pipeline now re-signs after Info.plist patching (was rejected with "App sandbox not enabled")
• Quarantine attributes stripped to fix ITMS-91109
• Auto-clears export compliance via App Store Connect API after upload

Install

```bash

Download the DMG, then:

hdiutil attach OpenMarkdownReader-1.0.5-universal.dmg
ditto /Volumes/OpenMarkdownReader/OpenMarkdownReader.app /Applications/OpenMarkdownReader.app
hdiutil detach /Volumes/OpenMarkdownReader
```

Universal binary (Intel + Apple Silicon), notarized.
