In April 2026 (2026-04), the maplibre-gl-js team delivered Marker Visibility Enhancements, focusing on making marker styling more flexible and visually accurate in 3D scenes. The work spanned API updates, CSS tooling for occlusion, tests, and documentation, culminating in a clearer, maintainable approach to marker visibility and state. Key outcomes include numeric opacity support for markers, a dedicated CSS class for occluded/covered markers, and updated docs/changelog to reflect naming and usage. This set of changes reduces integration friction for developers, improves rendering fidelity when markers interact with terrain or globe projection, and strengthens test coverage for visibility scenarios. The updates lay groundwork for future visual customization and safer refactors.
