Shapely 2.1.0 is a feature release with various new functions, improvements and bug fixes. Highlights include initial support for geometries with M or ZM values, functionality for coverage validation and simplification, and a set of new top-level functions.

Shapely supports Python >= 3.10, and binary wheels on PyPI include GEOS 3.13.1 and are now also provided for musllinux (Alpine) x86_64 platforms.

Shapely version 2.1.0 is a major release featuring various new functions, improvements and bug fixes. This is a first release candidate.

Shapely 2.0.7 fixes 3 bugs:

• Fix compilation error on certain Linux platforms, such as Alpine (#1945).
• Fixes crash when reading nonlinear geometry types (CircularString, CompoundCurve, MultiCurve, CurvePolygon, MultiSurface) from WKB/WKT with GEOS >= 3.13; these types are not yet supported in Shapely and now raise a NotImplementedError (#2160)
• Fix the project() method to return a Python float (#2093).

Wheels include GEOS 3.11.4.

For a full changelog, see https://shapely.readthedocs.io/en/latest/release/2.x.html#version-2-0-7.

Wheels are available for Python 3.13 (and still include GEOS 3.11.4).

Bug fixes:

• Fix compatibility with NumPy 2.1.0 (#2099).

For a full changelog, see https://shapely.readthedocs.io/en/latest/release/2.x.html#version-2-0-6

Binary wheels on PyPI include GEOS 3.11.4 from 2024-06-05. Furthermore, universal2 wheels are removed for macOS since both x86_64 and arm64 wheels are provided.

Bug fixes:

• Fix Point x/y/z attributes to return Python floats (#2074).
• Fix affinity for Apple silicon with NumPy 2.0 by reverting matmul, and use direct matrix multiplication instead (#2085).

For a full changelog, see https://shapely.readthedocs.io/en/latest/release/2.x.html#version-2-0-5

Wheels for Python versions >= 3.9 will be compatible with the upcoming NumPy 2.0 release (as well as with supported NumPy 1.x versions).

Bug fixes:

• Fix bug in to_wkt with multiple empty Z geometries (#2012).
• Fix bug in to_ragged_array for an array of Points with missing values (#2034).

For a full changelog, see https://shapely.readthedocs.io/en/latest/release/2.x.html#version-2-0-4

Bug fixes:

• Fix regression in the oriented_envelope ufunc to accept array-like input in case of GEOS<3.12 (#1929).

Packaging related:

• The binary wheels are not yet compatible with a future NumPy 2.0 release, therefore a numpy<2 upper pin was added to the requirements (#1972).
• Upgraded the GEOS version in the binary wheel distributions to 3.11.3.

For a full changelog , see https://shapely.readthedocs.io/en/latest/release/2.x.html#version-2-0-3

Bug fixes:

• Fix regression in the (in)equality comparison (geom1 == geom2) using __eq__ to
  not ignore the z-coordinates (#1732).
• Fix MultiPolygon() constructor to accept polygons without holes (#1850).
• Fix minimum_rotated_rectangle (oriented_envelope) to always return
  the minimum area solution (instead of minimum width). In practice, it will use the
  GEOS implementation only for GEOS 3.12+, and for older GEOS versions fall back to the
  implementation that was included in Shapely < 2 (#1670).
• Fix from_ragged_array to work with read-only array input (#1744).
• Fix the handling of z coordinates shapely.ops.substring (#1699).

Wheels are available for Python 3.12 (and still include GEOS 3.11.2). Building
from source is now compatible with Cython 3.

For a full changelog , see https://shapely.readthedocs.io/en/latest/release/2.x.html#version-2-0-2

Bug fixes:

• Fix regression in the Polygon() constructor taking a sequence of Points (#1662).
• Fix regression in the geometry constructors when passing decimal.Decimal coordinate values (#1707).
• Fix STRtree() to not make the passed geometry array immutable as side-effect of the constructor (#1714).
• Fix the directed keyword in shapely.ops.linemerge() (#1695).

Improvements:

• Expose the function to get a matplotlib Patch object from a (Multi)Polygon (without already plotting it) publicly as :func:shapely.plotting.patch_from_polygon (#1704).

For a full changelog, see https://shapely.readthedocs.io/en/latest/release/2.x.html#version-2-0-1

Shapely version 2.0.0 is a major release featuring a complete refactor of the internals and new vectorized (element-wise) array operations providing considerable performance improvements.

For a full changelog, see https://shapely.readthedocs.io/en/latest/release/2.x.html#version-2-0-0

Relevant changes in behaviour compared to 2.0rc3:

• Added temporary support for unpickling shapely<2.0 geometries.
