## v6.18.0

_April 21, 2026_

### Features

- Added `externalId` option to analytics state for custom tracking identifiers, configurable via `init()` and `updateState()`.
- Added `animated` option to `Markers.add()` which controls whether `Marker`s use opacity fade transitions. When set to `false`, visibility changes are instant. Configurable at runtime via `updateState()`.

```auto
const marker = mapView.Markers.add(coordinate, "<div>Hi</div>", { animated: false,});mapView.updateState(marker, { animated: true });

```

- Added `FloorStack` as a supported `Camera.focusOn()` target, enabling altitude-aware framing of multi-floor buildings.

### Performance

- Improved label rendering performance in dense scenes by reducing redundant draw operations.

### Fixes

- Fixed an issue where `Markers.animateTo()` did not visually move `Marker`s to the new position.
- Fixed an issue where multi-destination navigation connection path segments did not use the correct color for their parent path.
- Fixed an issue where degenerate void polygons could prevent the map from loading when multi-floor view ceiling cutouts were enabled.
