What's New in v0.20.0

CosmoQuickView v0.20.0 adds continuous integration, first-launch onboarding, richer error reporting, and an in-app update checker.

GitHub Actions CI Pipeline

A new continuous integration pipeline runs on every push and pull request. It builds and verifies the full hybrid stack:

• Go test suite
• Swift build of the Quick Look extension
• Coverage reporting

First-Launch Onboarding

The app now detects when a supported file extension is unregistered and guides you through enabling the plugin:

• Detects an unregistered extension on first launch
• Links directly to System Settings so you can enable CosmoQuickView

Enhanced Error Reporting

Previews that fail to render no longer show a blank panel. The app now presents a styled error page with a Report Issue link, making it easy to file a bug with the right context.

Check for Updates

A new Check for Updates... menu item compares your installed version against the latest release and shows whether an update is available (current vs latest version).
