contourpy/contourpy (contourpy)

v1.3.1: Version 1.3.1

Compare Source

ContourPy 1.3.1 is a compatibility release to support changes in bokeh, meson-python and pybind11.

This release supports Python 3.10 to 3.13.

Compatibility:

• Drop support for Python 3.9 (#​435)
• Update to bokeh 3.6.0 (#​444)
• Update minimum pybind11 to 2.13.2 (#​451)
• Read meson-python version in recommended way (#​452)

Code improvements:

• Use itertools.pairwise instead of zip where possible (#​437)
• Typing changes from ruff UP035 and UP038 (#​438)

Build, testing and CI improvements:

• Tidy up python 3.13 CI (#​449)
• Build Python 3.13t wheels on Windows (#​450)

v1.3.0: Version 1.3.0

Compare Source

ContourPy 1.3.0 adds new ContourGenerator functions multi_lines and multi_filled to calculate contour lines and filled contours over a sequence of levels in a single function call. There are also new functions to render, convert and dechunk the returns from multi_lines and multi_filled.

This release adds support for Python 3.13, including free-threaded. The latter should be considered experimental.

The use of np.nan as the lower_level or upper_level of ContourGenerator.filled() is no longer permitted.

Windows wheels uploaded to PyPI now bundle the C++ runtime statically to avoid problems with up and downstream libraries causing the use of incorrect DLLs.

This release supports CPython 3.9 to 3.13, and PyPy 3.9 to 3.10.

Thanks to new contributor @​lysnikolaou and core maintainer @​ianthomas23.

Enhancements:

• multi_lines and multi_filled:

  • ContourGenerator.multi_lines and multi_filled (#​338, #​340, #​342, #​343)

  • convert_multi_lines and convert_multi_filled (#​348)
  • dechunk_multi_lines and dechunk_multi_filled (#​345)

• Prevent use of np.nanas lower or upper level in filled (#​339)

Compatibility:

• Support PyPy 3.10 (#​404)

v1.2.0: Version 1.2.0

Compare Source

ContourPy 1.2.0 is a significant release with a number of new features. There is a new format for contour lines called LineType.ChunkCombinedNan that is designed to work directly with Bokeh and HoloViews. There are also new functions for manipulating contour lines and filled contours (convert_filled, convert_lines, dechunk_filled and dechunk_lines).

Calling ContourGenerator.filled() with two identical levels now raises a ValueError whereas previously it gave different results depending on algorithm name.

This release supports Python 3.9 to 3.12, and is the first release to ship musllinux aarch64 wheels.

Enhancements:

• Support strings as well as enums in renderer functions (#​284)
• Add new functions dechunk_filled and dechunk_lines (#​290)
• Add new functions convert_filled and convert_lines (#​291, #​293, #​294, #​312, #​313)
• Add new LineType.ChunkCombinedNan (#​296, #​301, #​308)
• Raise if call filled() with lower_level==upper_level (#​317)

Code improvements:

• Code quality improvements (#​282, #​310)
• Improvements to array checking functions (#​298)
• Better use of dtypes and casting when calling numpy functions (#​300, #​306, #​308, #​314)
• Update type annotations for Matplotlib 3.8 (#​303)
• Extra validation when dechunking and converting contour lines and filled contours (#​316)

Documentation improvements:

• Use versionadded sphinx directive (#​285)
• Remove threaded experimental warnings (#​297)
• Extract benchmark ratios when generating benchmark plots (#​302)
• Document new functions and conversion to Shapely geometries (#​318)

Build, testing and CI improvements:

• Add new CI run using NumPy nightly wheels (#​280)
• Test contour levels that are +/-np.inf (#​283)
• Improved PyPy CI (#​287, #​307)
• Use better names for enums when reporting parametrised tests (#​292)
• Improved mpl debug renderer tests (#​295)
• Support musllinux aarch64 (#​305)
• Run test suite in parallel (#​311)
• Miscellaneous build and CI improvements (#​279, #​281, #​288, #​315, #​319)
