• update dependencies

• support labels and icon rotation aligned with viewport

• add support for sprites

• fix an issue where curly brace expressions referencing a non-string property value could not be rendered as text

• add support for to-boolean expressions
• add support for sqrt expressions
• fix defect that occasionally caused tile layers not to be rendered if a minZoom or maxZoom was specified

Thanks to Gabriel Terwesten for their contributions.

• reduce memory overhead by filtering tile data with the theme

• make tileset compatible with passing between isolates

• improve support for theme expressions
• improve support for linear/exponential interpolation
• improve label placement to have fewer unlabelled roads
• improve efficiency of rendering by moving more calculations into the TilesetPreprocessor
• improve efficiency of rendering with a change to the vector_tile dependency

• reduce CPU overhead of text rendering

• introduce tileset preprocessing to reduce CPU overhead while rendering

• reduced memory overhead when rendering to a Canvas that is scaled and clipped
• reduced CPU overhead of text labels

• support multiple source tiles so that it's possible to have multiple data sources, for exmaple when rendering hillshade

• only abbreviate place names that appear at the end of text

• add theme versioning

• add abbreviations for place names

• improve label collision detection

• fix support for visibility=none layout

• improve text support with font family, italic, and text-transform
• avoid placing text on tile boundaries

• expose ID on themes

• reduce memory usage
• enable rendering within a clip to avoid using excessive raster cache
