editorconfig: Don’t use inline comments. Inline comments are invalid since editorconfig v0.15.0.

Fix publishing Linux/arm64 wheels, which did not work after switching the GHA manylinux wheel build step for arm64 to a real arm64 runner.

Fix Python version used for pre-commit at 3.13 so 3.14 is not used. Some linters like teyit are not compatible with Python 3.14.

Update Python version used for manylinux builds to 3.13

Run the GHA manylinux wheel build step for arm64 architecture on an actual Linux on arm64 VM instead of emulated on a x86_64 VM to speed things up.

Fix update_python_support script for the case when with-future-python is enabled.

Also check pyproject.toml when running check-python-versions.

Fix handling of tool section during pyproject.toml generation.

Add support for Python 3.14.

Drop support for Python 3.9.

Allow setuptools >= 78.1.1, <81.

Replace pkg_resources namespace with PEP 420 native namespace.

Update to pypy-3.11.

Add flag --no-tests to the scripts for switching to PEP 420 namespaces and for updating supported Python versions.

Add support for the --template-overrides flag to the Python version update script because it calls config-package.

Add ability to omit creating files by providing empty override templates.

Fixed a regression that removed GHA additional installs from the default template for GHA testing.

Upgrade setuptools pin to 75.8.2, which is extensively tested with the latest zc.buildout release 4.1.4. Package maintainers should update all their sandboxes to use ``setuptools==75.8.2`` and ``zc.buildout>=4.1.4`` to avoid issues with building and/or loading wheels!

Use Jinja templates to generate pyproject.toml files as well.

Add argument --template-overrides to configuration script to specify an additional configuration templates folder. This folder is expected to contain subfolders for each overridden configuration type or a default folder. The templates in these template folders will override the built-in templates.

Add argument --no-tests to configuration script to skip unit tests. Useful for quick iterative configuration or code changes.

Retire configurations require-cffi and additional-build-requirement. Build dependencies should go into pyproject.toml instead.

Fixes for changed wheel name issues with the latest setuptools/pip

Improve pyproject.toml generation

Add the tox release-check step to the c-code templates

Add script bin/switch-to-pep420 to convert a package from the old namespace package layout to the new PEP 420 native layout.

Add pyupgrade-exclude to [pre-commit] section in .meta.toml.

Drop support for Python 3.8.

Allow specifying a minimum supported Python version other than the previously hardcoded default of Python 3.8.

Allow setuptools <= 75.6.0.

Add omit option to coverage-run configuration because when defined in pyproject.toml it needs to be a list of strings.

Update setup.py of configured packages with small textual changes to match current best practices.

Converted to an installable Python package.
