Django 4.1: New Features for Handling Geometries

Django 4.1 brings two new features for handling geographic geometries; allowing developers to create valid and canonical geometries more easily:

• GEOSGeometry.make_valid() returns a valid representation of a geometry. Unless the geometry is already valid, then the geometry is returned without changes. The function is very similar to ST_MakeValid in PostGIS.
• GEOSGeometry.normalize() returns the canonical, or standardised, representation of a geometry. The method now accepts the optional clone keyword indicating that the normalisation must not change the geometry and instead return a new geometry object.

Additionally, support for GDAL 2.1 and PostGIS 2.4 has been removed, and the Django Admin’s OpenLayersWidget is now deprecated.
