We are pleased to announce a new release of GeoPandas!
GeoPandas 0.6.0 features a refactor of the internals based on the new
pandas ExtensionArray interface, for better integration with pandas.
Although this change should keep the user interface mostly stable, there
are a few changes summarized below. Further, this release includes a nice
set of other improvements and bug fixes. See the full list below.
Important note! This will be the last release to support Python 2.7 (#1031
GeoPandas can be installed with conda from the conda-forge channel (conda
install -c conda-forge geopandas) or with pip assuming the dependencies are
available for your platform or are already installed (pip install geopandas

*What is it?*
GeoPandas is an open source project to make working with geospatial data in
python easier. GeoPandas combines the capabilities of pandas and shapely,
providing geospatial operations in pandas and a high-level interface to
multiple shapely geometries. GeoPandas enables you to easily do operations
in python that would otherwise require a spatial database such as PostGIS.
Documentation can be found here: http://geopandas.readthedocs.io/en/stable/
- A refactor of the internals based on the pandas ExtensionArray
interface (#1000 <https://github.com/geopandas/geopandas/issues/1000>).
The main user visible changes are:
- The .dtype of a GeoSeries is now a 'geometry' dtype (and no longer
a numpy object dtype).
- The .values of a GeoSeries now returns a custom GeometryArray, and
no longer a numpy array. To get back a numpy array of Shapely
can convert explicitly using np.asarray(..).
- The GeoSeries constructor now raises a warning when passed
non-geometry data. Currently the constructor falls back to return a pandas
Series, but in the future this will raise an error (#1085
- The missing value handling has been changed to now separate the
concepts of missing geometries and empty geometries (#601
<https://github.com/geopandas/geopandas/issues/601>, 1062). In practice
this means that (see the docs
<https://geopandas.readthedocs.io/en/v0.6.0/missing_empty.html> for more
- GeoSeries.isna now considers only missing values, and if you want
to check for empty geometries, you can use GeoSeries.is_empty (
GeoDataFrame.isna already only looked at missing values).
- GeoSeries.dropna now actually drops missing values (before it
didn't drop either missing or empty geometries)
- GeoSeries.fillna only fills missing values (behaviour unchanged).
- GeoSeries.align uses missing values instead of empty geometries by
default to fill non-matching index entries.
New features and improvements:
- Addition of a GeoSeries.affine_transform method, equivalent of
Shapely's function (#1008
- Addition of a GeoDataFrame.rename_geometry method to easily rename the
active geometry column (#1053
- Addition of geopandas.show_versions() function, which can be used to
give an overview of the installed libraries in bug reports (#899
- The legend_kwds keyword of the plot() method can now also be used to
specify keywords for the color bar (#1102
- Performance improvement in the sjoin() operation by re-using existing
spatial index of the input dataframes, if available (#789
- Updated documentation to work with latest version of geoplot and
contextily (#1044 <https://github.com/geopandas/geopandas/pull/1044>,
- A new geopandas.options configuration, with currently a single option
to control the display precision of the coordinates (
options.display_precision). The default is now to show less coordinates
(3 for projected and 5 for geographic coordinates), but the default can be
overridden with the option.
- Also try to use pysal instead of mapclassify if available (#1082
- The GeoDataFrame.astype() method now correctly returns a GeoDataFrame
if the geometry column is preserved (#1009
- The to_crs method now uses always_xy=True to ensure correct lon/lat
order handling for pyproj>=2.2.0 (#1122
- Fixed passing list-like colors in the plot() method in case of "multi"
geometries (#1119 <https://github.com/geopandas/geopandas/pull/1119>).
- Fixed the coloring of shapes and colorbar when passing a custom norm
in the plot() method (#1091
- Fixed GeoDataFrame.to_file to preserve VFS file paths (e.g. when a
"s3://" path is specified) (#1124
- Fixed failing case in geopandas.sjoin with empty geometries (#1138
In addition, the minimum required versions of some dependencies have been
increased: GeoPandas now requires pandas >=0.23.4 and matplotlib >=2.0.1 (

*-- The GeoPandas developers*
The pycsw team announces the release of pycsw 2.4.0.
The 2.4.0 release adds WMS 1.3.0 and WPS process harvesting as well as
plugin support enhancements.
Note that though pycsw works with Python 2 and 3, we have turned
off Python 2 testing given the Python 2 end of life
scheduled for 01 January 2020. Users are strongly encouraged to update
their deployments to Python 3 as soon as possible.
