    - Now works properly on STATSGO data sets for individual states or CONUS. Previously tabular data would be transferred but spatial data were not.
  - `downloadSSURGO()` gains `db` argument which gives ability to download STATSGO by state or all of US from Web Soil Survey. Thanks to Meghan Krueger for suggestion.
  - `get_SDA_property()`: weighted average/dominant component numeric methods now return `mukey` in first column position; for parity with other `get_SDA*` methods recently updated/already doing this, making it easier to use these columns for raster attribute tables via `terra::set.levels()`

  - `fetchSDA_spatial()` gains `geom.src="mlrapolygon"` for obtaining Major Land Resource Area (MLRA) polygon boundaries. When using this geometry source `x` is a vector of `MLRARSYM` (MLRA Symbols).
