> This is the first official release of Mappedin JS v6 and React SDK v6. This version introduces the last breaking changes for both SDKs as the API becomes stable.

### ⚠ Breaking Changes

- `MapView.getState()` and `MapView.updateState()` no longer accept a `string` id. Instead, always pass the instance of the map element.

```ts
// ❌ Before
const space = mapView.getByType('space')[0];
const state = mapView.getState(space.id); // No longer supported
mapView.updateState(space.id, { opacity: 0.5 }); // No longer supported

// ✅ After
const space = mapView.getByType('space')[0];
const state = mapView.getState(space);
mapView.updateState(space, { opacity: 0.5 });

```

### Features

- Added `opacity` property to `LabelAppearance`.
- Added `areas` to the `mapView.on('click')` event.

### Fixes

- Fixed an issue with `Area`s rendering on all floors in multi-floor view.
- Fixed a regression causing `rank: 'always-visible'` `Label`s and `Marker`s to still fall back to the pin appearance.
