Add support for Python 3.15.

Publish C extension packages to PyPI only after the tests passed.

Add ability to run bin/update-python-support in CI.

Fix bin/update-python-support --auto-update failing when there is nothing left to commit, re-adding support for the newest Python version when there is no future one and choking on factor envs in tox.ini.

config-package only offers to update the branch protection rules when called with the new --admin option.

Drop support for Python 3.10, which reached end-of-life status on October 1, 2026.

Make Python 3.15 the newest released Python version.

Remove the future Python version value until Python 3.16 prereleases are available on GitHub.

Add .venv to .gitignore: tox 4.64+ writes a PEP 832 .venv redirect file into the project root.

Add uv.lock to .gitignore.

Allow setup-to-pyproject to run on a repository which is not controlled by zope.meta.

Add the check-case-conflict, check-merge-conflict, check-toml, check-yaml, end-of-file-fixer and trailing-whitespace hooks from pre-commit-hooks and the sphinx-lint hook to .pre-commit-config.yaml. Add whitespace-exclude and sphinx-lint-exclude to the [pre-commit] section in .meta.toml to hide files from them. (#284)

Stop rendering a blank line at the end of tests.yml for packages which do not use trusted publishing.

Fix the [pre-commit] example in the documentation: a backslash in a TOML basic string has to be escaped, so "error\.py" is not valid TOML.

Add [pre-commit] additional-config option to append additional repositories and hooks (e. g. mypy) to .pre-commit-config.yaml. (#439)

Offer to create a pull request via gh at the end of a config-package run, like update-python-support already does.

Use pinned commit hash for GH Action pypa/gh-action-pypi-publish. (#441)

Fix disappearing top comment in pyproject.toml with newer tomlkit. (#440)

Add [coverage] combine option to measure coverage across all supported Python versions instead of a single one. It turns the coverage tox environment into one which combines the data written by the test environments, and makes the coverage job in tests.yml run them.

Add [tox] coverage-deps option for dependencies only [testenv:coverage] needs, without them also landing in [testenv] and [testenv:setuptools-latest]. (#449)

Rotate the pip cache key weekly in the c-code test workflow template. actions/cache never replaces an existing key, so a corrupt cache entry used to break every run restoring it until GitHub evicted the entry. A rotating key abandons such an entry within a week instead.

Retry the pip install steps in the c-code test workflow template. PyPI downloads are occasionally cut off mid-transfer, and pip does not retry a truncated download, so the whole command is retried instead. This replaces the weekly pip cache key rotation, which did not address the actual cause. (#436)

Also set pip_pre for the free-threaded variant of a future Python version in tox.ini, as its dependencies are only available as pre-releases just like those of the non-free-threaded variant.

Upgrade pip via python -m pip in the c-code test workflow template, as the pip.exe shim on Windows refuses to replace itself. Run all workflow steps under bash so that a failing command in a multi-command block is no longer swallowed on Windows, and collapse the now-redundant OS-split pip cache steps. (#436)

Configure zest.releaser to not add an extra message when using trusted publishing.

Restrict readme-renderer dependency to versions older than 45 for the internal tests. This restriction can be removed when readme-renderer and its dependencies install cleanly under Python 3.15.

Expand free-threaded Python CI testing from Linux-only to all platforms (macOS, Windows) in c-code templates. Add future Python free-threaded variant (e.g. 3.15t) support to the test matrix, manylinux build scripts, and tox configuration.

Pre-install cffi and pycparser for future Python builds.

Switch to coverallsapp/github-action@v2 in the c-code test workflow template.

Add an option to enable releases to be built and published automatically using PyPI Trusted Publishing for non-c-code projects.

Move zest.releaser configuration from setup.cfg to pyproject.toml where it is the [tool.zest-releaser] section.

Update the setuptools version pin from <81 to <82. (#414)

Add steps to create a source distribution alongside binary wheels for the c-code template packages and publish it during releases. This prevents emailed warnings from PyPI about non-trusted publisher uploads. (#412)

Reinstate checking tests.yml in check-python-versions after the check-python-versions package was fixed. (See #396)

Pin “teyit” in precommitconfig.yaml.j2 to use Python 3.13 (must be available locally, like in path or via pyenv/uv). teyit does not support Python 3.14 yet. (#398)

Add folder share/ to .gitignore. The most recent versions of tox store manual pages there.

Add --with-free-threaded-python option to enable CI testing with the free-threaded (nogil) build of CPython. (#388)

Exclude tests.yml from check-python-versions when with-free-threaded-python is enabled, as 3.14t causes a mismatch. (#396)

Always publish free-threaded Python wheels to PyPI when with-free-threaded-python is enabled. (#394)

Add tox option testenv-skip-test-extra. Set this to true if your package does not have a test extra. Otherwise tests fail with latest tox.

Remove special treatment for macOS test runners on GitHub

Print out a warning if a setuptools install time dependency is found when runing the the config-package and setup-to-pyproject scripts.

Change c-code GitHub Actions publishing step to use PyPI’s “Trusted Publishing”. (#198)

Move package metadata from setup.py to pyproject.toml.

When moving metadata to pyproject.toml, ignore setup py test fossils. (#260)

Allow overriding configuration values in zope.meta.shared.packages by using the --overrides option and placing a TOML file named overrides.toml into the overrides folder.

Rename the --template-overrides option to simply --overrides.

Add option to show file changes after a failed tox lint run or not. For backwards compatibility this is still True if not set.

Add script to move package metadata from setup.py to pyproject.toml.

Move commonly used script argument processing into shared library file.

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.
