Mapbox GL JS v2.2.0 introduces significant enhancements, including optimized GeoJSON update performance in Safari, ensuring smoother rendering for dynamic data like vehicle tracking, which benefits services such as Instacart by providing seamless animations. This update also features level roofs on 3D terrain, correcting the rendering of building extrusions to be level relative to the earth rather than the terrain, improving visual accuracy for all fill-extrusion layers. Additionally, a new Continuous Integration (CI) test mode enables developers to integrate Mapbox GL JS into their automated testing without an access token, allowing for comprehensive test coverage and confident delivery of high-quality applications without incurring additional costs, as resources are loaded locally.
