geopandas/geopandas: v0.7.0

Support for Python 2.7 has been dropped. GeoPandas now works with Python >= 3.5.

The important API change of this release is that GeoPandas now requires PROJ > 6 and pyproj > 2.2, and that the .crs attribute of a GeoSeries and GeoDataFrame no longer stores the CRS information as a proj4 string or dict, but as a pyproj.CRS object (#1101).

This gives a better user interface and integrates improvements from pyproj and PROJ 6, but might also require some changes in your code. Check the migration guide in the documentation.

Other API changes:

• The GeoDataFrame.to_file method will now also write the GeoDataFrame index to the file, if the index is named and/or non-integer. You can use the index=True/False keyword to overwrite this default inference (#1059).

New features and improvements:

• A new geopandas.clip function to clip a GeoDataFrame to the spatial extent of another shape (#1128).
• The geopandas.overlay function now works for all geometry types, including points and linestrings in addition to polygons (#1110).
• The plot() method gained support for missing values (in the column that determines the colors). By default it doesn't plot the corresponding geometries, but using the new missing_kwds argument you can specify how to style those geometries (#1156).
• The plot() method now also supports plotting GeometryCollection and LinearRing objects (#1225).
• Added support for filtering with a geometry or reading a subset of the rows in geopandas.read_file (#1160).
• Added support for the new nullable integer data type of pandas in GeoDataFrame.to_file (#1220).

Bug fixes:

• GeoSeries.reset_index() now correctly results in a GeoDataFrame instead of DataFrame (#1252).
• Fixed the geopandas.sjoin function to handle MultiIndex correctly (#1159).
• Fixed the geopandas.sjoin function to preserve the index name of the left GeoDataFrame (#1150).
