mapbox-gl

Features and improvements

• Improve performance on map views with CJK glyphs by moving CJK rasterization offscreen.

• Improve tile load performance via optimization of style property values recalculation.

• Improve rendering performance via per-frame main thread work optimizations.

• Add support of *-ignore-placement and *-allow-overlap in global placement.

• Add raster-mask and raster-mask-mode paint properties so a raster layer can be clipped to, or excluded from, the geometry of a fill layer

Bug fixes

• Fix coverage stencil marks including polygons for other road classes, which hid roads that should stay visible.

• Fix imported styles silently rendering nothing when the import fires a non-fatal error while loading.

• Fix raster tiles occasionally showing the image of a different tile after zooming or panning on a slow network.

• Fix building layer filters that use distance, within or worldview dropping buildings.

• Fix a sudden camera jump at the end of long flyTo camera animations.

• Fix 0 fadeDuration symbol placement offset.

• Fix projection documentation incorrectly stating that custom layers are not supported on globe.

• Fix per-feature symbol/line paint value update based on light changes.

Breaking changes

• breaking

  Right-to-left text (such as Arabic and Hebrew) is now supported out of the box, loading a small WebAssembly module the first time it appears on the map. setRTLTextPlugin, getRTLTextPluginStatus and the PluginStatus type are removed.

• breaking

  The base size of icons in the text-field property is now calculated at the tile zoom level with the largest text size. As a result, the icons can be smaller when the text size depends on the zoom level.

Features and improvements

• Improve memory use & map load time, especially for 3D layers.

• Improve line rendering performance by using a uniform instead of a shader permutation for line-dasharray.

• Add support for offsetting a control from its corner via map.addControl(control, {position, offset: {x, y}}).

• Improve 3D Lanes map load performance.

• Avoid placing parent-tile symbols when using the global placement.

• Extend global placement debug info.

Bug fixes

• Fix a severe performance regression when updating data-driven line layers with setPaintProperty.

• Fix a rendering issue when drawing thousands of data-driven lines and symbols.

• Fix transparent building and fill-extrusion layers blending the same pixel twice where they cover the same buildings, making the overlap look more opaque than either layer's opacity asks for.

• Fix an issue with GeoJSON geometries past longitude -+360 or latitude +-85 rendering incorrectly.

• Fix map-aligned icon-rotate and text-rotate not being measured from true north in projections other than Mercator or globe, which misrotated symbols such as crosswalks.

• Fix collision boxes not matching rotated symbols that use appearances with a layout icon-rotate or text-rotate.

• Fix symbol fading not finishing when using global placement.
