Version 0.35 brings a number of new features, including significant performance enhancements useful for complex scenes with numerous data sources.
Performance improvements
These improvements mainly concern the display of raster data (color or elevation) on the Map entity:
- Reduced memory usage of Map tiles
- Reduced image display latency on the Map
- Reduction in the number of HTTP requests made
- Increased tile processing speed
New features
