Version 0.22 (August 4, 2023)#

Cartopy v0.22 is a major step forward in the project’s development. The requirement to install with local PROJ and GEOS libraries has been removed. The previous C PROJ library calls have been replaced by pyproj and the C GEOS calls have been replaced by shapely. This means that Cartopy can now be installed with a simple pip install cartopy.
