 ### Changed
 
 - breaking: Updated compat for GDAL.jl 1.5 and fixed tests for GDAL 3.6. These include changes to `gdalnearblack`, `fillunsetwithdefault!` and `gdalgetgeotransform`.
+- breaking: Use `GeoInterface.convert` instead of `convert` to convert geometries from other
+  packages to ArchGDAL via the GeoInterface. Example: `GeoInterface.convert(AG.IGeometry, geom)`
