# v0.0.80rc4 - Dynamic Links & Scene Refactor

## Dynamic Link/Unlink

Links can now be added and removed at runtime via `vuer.workspace`:

```python
from vuer import Vuer
from vuer.workspace import jpg

vuer = Vuer()

@vuer.spawn(start=True)
async def main(session):
    # Add links dynamically
    vuer.workspace.link(lambda: jpg(camera.frame), "/live/frame.jpg")
    vuer.workspace.link(lambda: {"status": "recording"}, "/api/status")

    # Access at /workspace/live/frame.jpg

    await do_recording()

    # Remove when done
    vuer.workspace.unlink("/live/frame.jpg")

    await session.forever()
```

## Scene Refactor

- **`Scene`** is now minimal with empty `bgChildren` by default

- **`DefaultScene`** includes rich defaults:

  - Grid, HemisphereLightStage, Gamepad, Hands, MotionControllers
  - SceneCamera (position `[0, 5, 10]`), SceneCameraControl
  - CameraPreviewThumbs, CameraPreviewOverlay

- Removed deprecated parameters: `defaultLights`, `defaultOrbitControls`, `show_helper`

## Other Changes

- Updated `params-proto` to 3.2.4
