• Undo is now on by default in the web UI. Untick enable undo in the History menu to turn it off, which you may want to do when working with very large datasets.
• Mapshaper now correctly re-imports the .aux.xml sidecar it writes when saving a GeoTIFF in a projection that standard GeoTIFF metadata cannot describe.
• A GeoTIFF with no CRS metadata is treated as WGS84 lat-long if the coordinates are in the decimal-degree range (this is consistent with how vector data is handled).
• GeoTIFF is now the default format for exporting rasters in the web UI.
