Changelog

1.3.1

pybind11``.

This release supports Python 3.10 to 3.13.

Compatibility:

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

Code improvements:

- Use ``itertools.pairwise`` instead of ``zip`` where possible (:pr:`437`)
- Typing changes from ``ruff`` UP035 and UP038 (:pr:`438`)

Build, testing and CI improvements:

- Tidy up python 3.13 CI (:pr:`449`)
- Build Python 3.13t wheels on Windows (:pr:`450`)

1.3.0

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 :user:`lysnikolaou` and core maintainer :user:`ianthomas23`.

- ``convert_multi_lines`` and ``convert_multi_filled`` (:pr:`348`)
- ``dechunk_multi_lines`` and ``dechunk_multi_filled`` (:pr:`345`)

- Prevent use of ``np.nan`` as lower or upper level in ``filled`` (:pr:`339`)
