Development changes
-------------------
Windows wheel runtime bundling
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Wheels built for Windows now bundle the MSVC runtime DLL ``msvcp140.dll``. This
enables importing Matplotlib on systems that do not have the runtime installed.
Increase to minimum supported versions of dependencies
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
For Matplotlib 3.7, the :ref:`minimum supported versions <dependencies>` are
being bumped:
+------------+-----------------+---------------+
| Dependency | min in mpl3.6 | min in mpl3.7 |
+============+=================+===============+
| NumPy | 1.19 | 1.20 |
+------------+-----------------+---------------+
| pyparsing | 2.2.1 | 2.3.1 |
+------------+-----------------+---------------+
| Qt | | 5.10 |
+------------+-----------------+---------------+
- There are no wheels or conda packages that support both Qt 5.9 (or older) and
Python 3.8 (or newer).
This is consistent with our :ref:`min_deps_policy` and `NEP29
<https://numpy.org/neps/nep-0029-deprecation_policy.html>`__
New dependencies
~~~~~~~~~~~~~~~~
* `importlib-resources <https://pypi.org/project/importlib-resources/>`_
(>= 3.2.0; only required on Python < 3.10)
Maximum line length increased to 88 characters
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The maximum line length for new contributions has been extended from 79 characters to
88 characters.
This change provides an extra 9 characters to allow code which is a single idea to fit
on fewer lines (often a single line).
The chosen length is the same as `black <https://black.readthedocs.io/en/stable/the_black_code_style/current_style.html#line-length>`_.
