Mapbox GL JS 3

Mapbox GL JS 3 introduces the Mapbox Standard style and a high-performance 3D rendering engine for web-based spatial data.

Version 3 elevates web mapping through the Mapbox Standard style: a comprehensive basemap featuring dynamic lighting, 3D landmarks, and high-fidelity shadows. It leverages a revamped rendering engine to handle complex data layers while maintaining 60 FPS performance. Developers access advanced features like the Globe projection, terrain elevation, and seamless integration with the Mapbox Search and Directions APIs. This release simplifies styling through a slot-based system (enabling easy insertion of custom layers into the Standard basemap) and ensures compatibility across modern browsers via WebGL 2.0.
