## What’s new

### Multiple Local & Remote System Configuration Sources

You can now compose your effective `system.json` from **multiple local + remote sources** , assign **priority** , and let the platform **merge** everything into a final system configuration.

Docs (changelog): [io.Connect Desktop Documentation - Changelog \> io.Connect Desktop 10.0.3](https://docs.interop.io/desktop/getting-started/changelog/10-0-3/index.html#new_features-multiple_local__remote_system_configuration_sources)

### Custom Environment Variables

You can now define your own environment variables via `envVars.set` in `system.json` and use them across your config and app definitions. This also works with multi-source configuration, where higher-priority sources override lower-priority values.

Docs (changelog): [io.Connect Desktop Documentation - Changelog \> io.Connect Desktop 10.0.3](https://docs.interop.io/desktop/getting-started/changelog/10-0-3/index.html#new_features-custom_environment_variables)

### Workspaces App Dialog Blur (advanced mode)

If you’re using the Workspaces App and want a more polished dialog experience, you can now blur the area around a displayed dialog (via `FrameDialogOptions.blur`). Note: this is **advanced platform mode only**.

Docs (changelog): [io.Connect Desktop Documentation - Changelog \> io.Connect Desktop 10.0.3](https://docs.interop.io/desktop/getting-started/changelog/10-0-3/index.html#new_features-workspaces_app_dialog_blur)

### Persisting Window Zoom (zoom mode = “window”)

If you use the `"window"` zoom behavior, zoom factors for web app instances are now **persisted automatically** and restored across refresh/restart, and when saving windows in Global Layouts or Workspaces. New instances of the same app pick up the **last persisted** zoom factor.

Docs (changelog): [io.Connect Desktop Documentation - Changelog \> io.Connect Desktop 10.0.3](https://docs.interop.io/desktop/getting-started/changelog/10-0-3/index.html#new_features-persisting_window_zoom)

### Trusted App Stores (FDC3 security behavior)

When pulling FDC3 app definitions from public directories, io.Connect Desktop applies your platform security settings (from `system.json`) by default. If you store FDC3 definitions in an io.Connect app store and want to **preserve** their security settings, you can now mark that store as **trusted**.

Docs (changelog): [https://docs.interop.io/desktop/getting-started/changelog/10-0-3/index.html#new\_features-trusted\_app\_stores](https://docs.interop.io/desktop/getting-started/changelog/10-0-3/index.html#new_features-trusted_app_stores)
