+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 The previous C PROJ library calls have been replaced by pyproj
+and the C GEOS calls have been replaced by shapely.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``.
+
+
+For a full list of included Pull Requests and closed Issues, please see the
+`0.22 milestone <https://github.com/SciTools/cartopy/milestone/35>`_.
