## Houston 0.4.0

First release on the new engine architecture.

### What's new

- Product prompts now live in the app, engine is a standalone platform binary
- Data consolidates under `~/.houston/` (workspaces move out of `~/Documents/Houston/` automatically on first launch)
- Real-time reactivity restored — the board updates live when agents write files
- Race-free engine startup + sidecar signing + notarization verified in CI
- Drag-and-drop file attachments fixed
- Onboarding detects your Claude/Codex CLI from any standard install location
- Routines tab auto-detects your timezone (change it in Settings)

### Before you upgrade

- Quit Houston before installing. macOS doesn't always replace a running app. If in doubt: `rm -rf /Applications/Houston.app` and drag the new copy in.
- Your workspaces will move from `~/Documents/Houston/` to `~/.houston/workspaces/` on first launch. The old location stays as a backup.
- If you have custom scripts pointing at the old path, update them.

### Known limitations

- Claude and Codex CLIs must still be installed separately. Bundled-CLI install is coming in a later release.
