Version 0.10 (2021-05-18)

Major enhancements

• Addition of nearest and nearest_all functions to STRtree for
  GEOS >= 3.6 to find the nearest neighbors (#272).
• Enable bulk construction of geometries with different number of coordinates
  by optionally taking index arrays in all creation functions (#230, #322, #326, #346).
• Released the GIL in all geometry creation functions (#310, #326).
• Added the option to return the geometry index in get_coordinates (#318).
• Added the get_rings function, similar as get_parts but specifically
  to extract the rings of Polygon geometries (#342).
• Updated box ufunc to use internal C function for creating polygon
  (about 2x faster) and added ccw parameter to create polygon in
  counterclockwise (default) or clockwise direction (#308).
• Added to_shapely and improved performance of from_shapely in the case
  GEOS versions are different (#312).

API Changes

• STRtree default leaf size is now 10 instead of 5, for somewhat better performance
  under normal conditions (#286)
• Deprecated VALID_PREDICATES set from pygeos.strtree package; these can be constructed
  in downstream libraries using the pygeos.strtree.BinaryPredicate enum.
  This will be removed in a future release.
• points, linestrings, linearrings, and polygons now return a GEOSException
  instead of a ValueError or TypeError for invalid input (#310, #326).
• Addition of on_invalid parameter to from_wkb and from_wkt to
  optionally return invalid WKB geometries as None.
• Removed the (internal) function lib.polygons_without_holes and renamed
  lib.polygons_with_holes to lib.polygons (#326).
• polygons will now return an empty polygon for None inputs (#346).
• Removed compatibility with Python 3.5 (#341).

Added GEOS functions

• Addition of a contains_properly function (#267)
• Addition of a polygonize function (#275)
• Addition of a polygonize_full function (#298)
• Addition of a segmentize function for GEOS >= 3.10 (#299)
• Addition of oriented_envelope and minimum_rotated_rectangle functions (#314)
• Addition of minimum_bounding_circle and minimum_bounding_radius functions for GEOS >= 3.8 (#315)
• Addition of a shortest_line ("nearest points") function (#334)

Bug fixes

• Fixed portability issue for ARM architecture (#293)
• Fixed segfault in linearrings and box when constructing a geometry with nan
  coordinates (#310).
• Fixed segfault in polygons (with holes) when None was provided.
• Fixed memory leak in polygons when non-linearring input was provided.

Version 0.9 (2021-01-23)

Major enhancements

• Addition of prepare function that generates a GEOS prepared geometry which is stored on
  the Geometry object itself. All binary predicates (except equals) make use of this.
  Helper functions destroy_prepared and is_prepared are also available. (#92, #252)
• Use previously prepared geometries within STRtree query and query_bulk
  functions if available (#246)
• Official support for Python 3.9 and numpy 1.20 (#278, #279)
• Drop support for Python 3.5 (#211)
• Added support for pickling to Geometry objects (#190)
• The apply function for coordinate transformations and the set_coordinates
  function now support geometries with z-coordinates (#131)
• Addition of Cython and internal PyGEOS C API to enable easier development of internal
  functions (previously all significant internal functions were developed in C).
  Added a Cython-implemented get_parts function (#51)

API Changes

• Geometry and counting functions (get_num_coordinates,
  get_num_geometries, get_num_interior_rings, get_num_points) now return 0
  for None input values instead of -1 (#218)
• intersection_all and symmetric_difference_all now ignore None values
  instead of returning None if any value is None (#249)
• union_all now returns None (instead of GEOMETRYCOLLECTION EMPTY) if
  all input values are None (#249)
• The default axis of union_all, intersection_all, symmetric_difference_all,
  and coverage_union_all can now reduce over multiple axes. The default changed from the first
  axis (0) to all axes (None) (#266)
• Argument in line_interpolate_point and line_locate_point
  was renamed from normalize to normalized (#209)
• Addition of grid_size parameter to specify fixed-precision grid for difference,
  intersection, symmetric_difference, union, and union_all operations for
  GEOS >= 3.9 (#276)

Added GEOS functions

• Release the GIL for is_geometry(), is_missing(), and
  is_valid_input() (#207)
• Addition of a is_ccw() function for GEOS >= 3.7 (#201)
• Addition of a minimum_clearance function for GEOS >= 3.6.0 (#223)
• Addition of a offset_curve function (#229)
• Addition of a relate_pattern function (#245)
• Addition of a clip_by_rect function (#273)
• Addition of a reverse function for GEOS >= 3.7 (#254)
• Addition of get_precision to get precision of a geometry and set_precision
  to set the precision of a geometry (may round and reduce coordinates) (#257)

Bug fixes

• Fixed internal GEOS error code detection for get_dimensions and get_srid (#218)
• Limited the length of geometry repr to 80 characters (#189)
• Fixed error handling in line_locate_point for incorrect geometry
  types, now actually requiring line and point geometries (#216)
• Addition of get_parts function to get individual parts of an array of multipart
  geometries (#197)
• Ensure that python setup.py clean removes all previously Cythonized and compiled
  files (#239)
• Handle GEOS beta versions (#262)
