11.19.0-rc.1 February 12, 2026

Features ✨ and improvements 🏁

• Improve data serialization speed when using LineString or MultiPoint in GeoJsonSource.
• Introduce new LineLayer.lineElevationGroundScale property to scale elevated lines with terrain exaggeration.
• Promote elevated lines properties to stable: LineLayer.lineZOffset and LineLayer.lineElevationReference.
• Introduce experimental SymbolScaleBehavior API to automatically scale map symbols (icons and text) based on system accessibility text size settings. Set MapboxMap.symbolScaleBehavior property to configure: SymbolScaleBehavior.system (automatic scaling), SymbolScaleBehavior.system(mapping) (custom mapping function), or SymbolScaleBehavior.fixed(scaleFactor) (fixed scale, default is 1.0). Valid scale factor range is [0.8, 2.0]. Automatic scaling is opt-in; symbols default to fixed 1.0x scale.
• General fixes and performance improvements.

Bug fixes 🐞

• Fixed a potential leak of animators, which resulted in the absence of MapIdle events.
• Fix elevated line bevel join artifacts at sharp corners.
• [compose] Improved reliability of attribution list updates on source change.
