Breaking changes

• breaking

  This release marks a significant transition for GL JS, moving from Flow to TypeScript. While we have maintained backward compatibility where possible, the community typings @types/mapbox-gl are not fully compatible with the new first-class typings. Users relying on the community typings may experience breaking changes. Please remove the @types/mapbox-gl dependency and refer to the v3.5.0 migration guide for instructions on upgrading, resolving common issues, and asking questions regarding the migration to the first-class typings. We welcome your feedback and contributions to make Mapbox GL JS better.

• Add model-cutoff-fade-range property to control fade out of faraway 3D buildings.
