Version 8.4.2

Released 2026-06-24

• Fix Fish shell completion broken in 8.4.0 by {pr}3126. Newlines and tabs in option help text are now escaped, keeping the original completion format while still supporting multi-line help. {issue}3502 {issue}3043 {pr}3504 {pr}3508
• Deprecated commands and options with empty or missing help text no longer render a stray leading space before the (DEPRECATED) label. {pr}3509
• A {class}Group with invoke_without_command=True marks its subcommand as optional in the usage help, showing [COMMAND] instead of COMMAND. {issue}3059 {pr}3507
• echo_via_pager flushes after each write, so passing a generator streams output to the pager incrementally instead of staying hidden until the pipe buffer fills. {issue}3242 {issue}2542 {pr}3534
• echo_via_pager and get_pager_file no longer close a borrowed stdout stream when no external pager runs, completing the partial I/O operation on closed file fix from {pr}3482. {issue}3449 {pr}3533
• Fix CLI usage symopsis for optional arguments producing double square brackets [[a|b|c]]... whose type already brackets their metavar. {pr}3578
• {func}version_option resolves a package_name that does not match an installed distribution as an import (top-level module) name via {func}importlib.metadata.packages_distributions. Packages whose top-level module name differs from their distribution name (PIL vs Pillow, jwt vs PyJWT) no longer raise RuntimeError out of the box. {issue}2331 {issue}1884 {issue}3125 {pr}3582

Version 8.4.1

Released 2026-05-21

• get_parameter_source() is available during eager callbacks and type conversion again. {issue}3458 {pr}3484
• Zsh completion scripts parse correctly on Windows. {issue}3277 {pr}3466
• Shell completion of Enum values used as Choice options produces a valid completion result. {issue}3015 {pr}3471
• Fix empty byte-string handling in echo. {issue}3487 {pr}3493
• Fix closed file error with echo_via_pager. {issue}3449 {pr}3482
• Fix open_url on Windows when the file path contains spaces. {issue}2994 {pr}3478

9.1.1

pytest 9.1.1 (2026-06-19)

Bug fixes

• #14220: Fixed a logic bug in pytest.RaisesGroup which would might cause it to display incorrect "It matches FooError() which was paired with BarError" messages.
• #14591: Fixed a regression in pytest 9.1.0 which caused overriding a parametrized fixture with an indirect @​pytest.mark.parametrize to fail with "duplicate parametrization of '<fixture name>'".
• #14606: Fixed list-item typing errors from mypy in @pytest.mark.parametrize <pytest.mark.parametrize ref> argvalues parameter.
• #14608: Fixed a regression in pytest 9.1.0 where conftest.py files located in <invocation dir>/test* were no longer loaded as initial conftests when invoked without arguments. This could cause certain hooks (like pytest_addoption) in these files to not fire.

9.1.0

pytest 9.1.0 (2026-06-13)

Removals and backward incompatible breaking changes

• #14533: When using --doctest-modules, autouse fixtures with module, package or session scope that are defined inline in Python test modules (not plugins or conftests) will now possibly execute twice.

  If this is undesirable, move the fixture definition to a conftest.py file if possible.

  Technical explanation for those interested: When using --doctest-modules, pytest possibly collects Python modules twice, once as pytest.Module and once as a DoctestModule (depending on the configuration). Due to improvements in pytest's fixture implementation, if e.g. the DoctestModule collects a fixture, it is now visible to it only, and not to the Module. This means that both need to register the fixtures independently.

Deprecations (removal in next major release)

• #10819: Added a deprecation warning for class-scoped fixtures defined as instance methods (without @classmethod). Such fixtures set attributes on a different instance than the test methods use, leading to unexpected behavior. Use @classmethod decorator instead -- by yastcher.

  See 10819 and 14011.

• #12882: Calling request.getfixturevalue() <pytest.FixtureRequest.getfixturevalue> during teardown to request a fixture that was not already requested is now deprecated and will become an error in pytest 10.

  See dynamic-fixture-request-during-teardown for details.

• #13409: Using non-~collections.abc.Collection iterables (such as generators, iterators, or custom iterable objects) for the argvalues parameter in @pytest.mark.parametrize <pytest.mark.parametrize ref> and metafunc.parametrize <pytest.Metafunc.parametrize> is now deprecated.

  These iterables get exhausted after the first iteration, leading to tests getting unexpectedly skipped in cases such as running pytest.main() multiple times, using class-level parametrize decorators, or collecting tests multiple times.

  See parametrize-iterators for details and suggestions.

• #13946: The private config.inicfg attribute is now deprecated. Use config.getini() <pytest.Config.getini> to access configuration values instead.

  See config-inicfg for more details.

• #14004: Passing baseid to ~pytest.FixtureDef or nodeid strings to fixture registration APIs is now deprecated. These are internal pytest APIs that are used by some plugins.

Sourced from setuptools-scm's releases.

setuptools-scm v10.2.0

Added

• Restore Python 3.8 and 3.9 support, re-enabling use as a build dependency for projects like scikit-build that still support these versions. (#1445)

Miscellaneous

• Move PKG-INFO discovery tests from vcs-versioning to setuptools-scm where the entry points are registered. (#1446)

setuptools-scm v10.1.2

Fixed

• Fix DeprecationWarning leak by threading VcsEnvironment through VersionInferenceConfig and using env.make_reader() in _should_write_to_source. (#1424)

setuptools-scm v10.1.1

Fixed

• Update CI to use PyPy 3.11 as cryptography has no PyPy 3.10 build available (#1421)

setuptools-scm v10.1.0

Added

• Add backward-compatible shims in setuptools_scm.git, setuptools_scm.hg, setuptools_scm.hg_git, and setuptools_scm.scm_workdir so that external code calling get_scm_version(config) or run_describe(config) with an explicit Configuration continues to work. The shim automatically wires _config and VcsEnvironment onto the workdir. (#compat-shims)
• Write scm_version.json and scm_file_list.json into egg-info directories during egg_info, enabling sdist fallback version inference when no VCS is present. Add ScmEggInfoMixin for workdir-based file finding in find_sources(). (#egg-info-metadata)
• Add write_to_source pyproject.toml option to control whether version files are written to the source tree. When unset, a deprecation warning advises setting it explicitly before the default changes in a future major release. The SETUPTOOLS_SCM_WRITE_TO_SOURCE environment variable overrides this setting. (#1301)
• Adopt the workdir-centric pipeline from vcs-versioning: version discovery now follows an explicit env → config → workdir → version chain instead of relying on ambient globals and parse entry points. The egg_info command writes scm_version.json and scm_file_list.json metadata so sdists can infer versions without a VCS checkout. Requires vcs-versioning >= 2.0.0.dev0. (#1378)

Fixed

• Fix worktree file listing test to expect relative paths from the file finder. The test now passes on Linux; Windows remains xfail due to a subprocess limitation with worktree directories. (#620)
• Remove the _warn_on_old_setuptools() check that incorrectly warned when a custom build-backend caused setuptools.__version__ to return the project version instead of setuptools' version. The minimum setuptools version is now enforced via build-system requirements. (#1192)
• Wrap version in setuptools.sic() when normalize = false to prevent setuptools from re-normalizing the version after our hook returns. This preserves CalVer zero-padding (e.g. 2024.01.05) and other non-canonical version strings in dist.metadata.version. (#1354)
• Skip writing non-package version files to build_lib, fixing incorrect inclusion of root-level version files in wheels. (#1364)

Documentation

• Rewrite the GitHub Actions CI/CD example to use a dedicated build job (via build-and-inspect-python-package) and OIDC Trusted Publishers instead of building in publishing jobs with long-lived API tokens. (#1215)
