API changes:

- A refactor of the internals based on the pandas ExtensionArray interface (#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 scalars, you 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, 1062). In practice this means that (see [the docs](https://geopandas.readthedocs.io/en/v0.6.0/missing_empty.html) for more details):
|

|
|
|
|
|

- `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).
