8.4.2

pytest 8.4.2 (2025-09-03)

Bug fixes

• #13478: Fixed a crash when using console_output_style{.interpreted-text role="confval"} with times and a module is skipped.

• #13530: Fixed a crash when using pytest.approx{.interpreted-text role="func"} and decimal.Decimal{.interpreted-text role="class"} instances with the decimal.FloatOperation{.interpreted-text role="class"} trap set.

• #13549: No longer evaluate type annotations in Python 3.14 when inspecting function signatures.

  This prevents crashes during module collection when modules do not explicitly use from __future__ import annotations and import types for annotations within a if TYPE_CHECKING: block.

• #13559: Added missing [int]{.title-ref} and [float]{.title-ref} variants to the [Literal]{.title-ref} type annotation of the [type]{.title-ref} parameter in pytest.Parser.addini{.interpreted-text role="meth"}.

• #13563: pytest.approx{.interpreted-text role="func"} now only imports numpy if NumPy is already in sys.modules. This fixes unconditional import behavior introduced in [8.4.0]{.title-ref}.

Improved documentation

• #13577: Clarify that pytest_generate_tests is discovered in test modules/classes; other hooks must be in conftest.py or plugins.

Contributor-facing changes

• #13480: Self-testing: fixed a few test failures when run with -Wdefault or a similar override.
• #13547: Self-testing: corrected expected message for test_doctest_unexpected_exception in Python 3.14.
• #13684: Make pytest's own testsuite insensitive to the presence of the CI environment variable -- by ogrisel{.interpreted-text role="user"}.

7.0.0 (2025-09-09)

• Dropped support for subprocesses measurement.

  It was a feature added long time ago when coverage lacked a nice way to measure subprocesses created in tests. It relied on a .pth file, there was no way to opt-out and it created bad interations with coverage's new patch system <https://coverage.readthedocs.io/en/latest/config.html#run-patch>_ added in 7.10 <https://coverage.readthedocs.io/en/7.10.6/changes.html#version-7-10-0-2025-07-24>_.

  To migrate to this release you might need to enable the suprocess patch, example for .coveragerc:

  .. code-block:: ini

  [run] patch = subprocess

  This release also requires at least coverage 7.10.6.

• Switched packaging to have metadata completely in pyproject.toml and use hatchling <https://pypi.org/project/hatchling/>_ for building. Contributed by Ofek Lev in [#551](https://github.com/pytest-dev/pytest-cov/issues/551) <https://github.com/pytest-dev/pytest-cov/pull/551>_ with some extras in [#716](https://github.com/pytest-dev/pytest-cov/issues/716) <https://github.com/pytest-dev/pytest-cov/pull/716>_.

• Removed some not really necessary testing deps like six.

6.3.0 (2025-09-06)

• Added support for markdown reports. Contributed by Marcos Boger in [#712](https://github.com/pytest-dev/pytest-cov/issues/712) <https://github.com/pytest-dev/pytest-cov/pull/712>_ and [#714](https://github.com/pytest-dev/pytest-cov/issues/714) <https://github.com/pytest-dev/pytest-cov/pull/714>_.

v4.30.3 (2025-10-02)

Bugfixes - 4.30.3

- Fix incorrect type annotation in ``PythonPathPackageWithDeps.__init__()``
  where ``deps`` was annotated as ``Sequence[Package]`` but should be
  ``Sequence[Requirement]`` to match actual runtime usage - by :user:`PreistlyPython` (:issue:`3607`)
- Fix ``None`` appearing as the config filename in error output
  when the user's default config file is corrupt. - by :user:`kurtmckee` (:issue:`3611`)
v4.30.2 (2025-09-04)
Bugfixes - 4.30.2

• Previously, when tox ran in an automatically provisioned environment, it could hang waiting for a PEP 517 build backend if used in conjunction with the --installpkg option. This has been fixed by properly tearing down the automatically provisioned environment after the tests.
  • by :user:vytas7 (:issue:3600)

v4.30.1 (2025-09-03)

Bugfixes - 4.30.1

- Prevent tox from hanging upon exit due to orphaned build threads and subprocesses when the ``--installpkg`` option is
  used with *sdist*.
  - by :user:`vytas7` (:issue:`3530`)
v4.30.0 (2025-09-03)
Features - 4.30.0

• Add __TOX_ENVIRONMENT_VARIABLE_ORIGINAL_CI, which passes through the CI variable if present. This is intended for use by other libraries to detect if tox is running under CI. (:issue:3442)

Bugfixes - 4.30.0

- Makes the error message more clear when pyproject.toml file cannot be loaded
  or is missing expected keys. (:issue:`3578`)
- The :func:`tox_extend_envs() hook <tox.plugin.spec.tox_extend_envs>`
  recently added in :pull:`3591` turned out to not work well with
  ``tox run``. It was fixed internally, not to exhaust the underlying
  iterator on the first use.

Mypy Release Notes

Next Release

Drop Support for Python 3.9

Mypy no longer supports running with Python 3.9, which has reached end-of-life. When running mypy with Python 3.10+, it is still possible to type check code that needs to support Python 3.9 with the --python-version 3.9 argument. Support for this will be dropped in the first half of 2026!

Contributed by Marc Mueller (PR 20156).

Mypy 1.19

We’ve just uploaded mypy 1.19.0 to the Python Package Index (PyPI). Mypy is a static type checker for Python. This release includes new features, performance improvements and bug fixes. You can install it as follows:

python3 -m pip install -U mypy

You can read the full documentation for this release on Read the Docs.

Python 3.9 Support Ending Soon

This is the last mypy feature release that supports Python 3.9, which reached end of life in October 2025.

Performance Improvements

• Switch to a more dynamic SCC processing logic (Ivan Levkivskyi, PR 20053)
• Speed up type aliases (Ivan Levkivskyi, PR 19810)

Fixed‑Format Cache Improvements

Mypy uses a cache by default to speed up incremental runs by reusing partial results from earlier runs. Mypy 1.18 added a new binary fixed-format cache representation as an experimental feature. The feature is no longer experimental, and we are planning to enable it by default in a future mypy release (possibly 1.20), since it's faster and uses less space than the original, JSON-based cache format. Use --fixed-format-cache to enable the fixed-format cache.

Mypy now has an extra dependency on the librt PyPI package, as it's needed for cache serialization and deserialization.

Mypy ships with a tool to convert fixed-format cache files to the old JSON format. Example of how to use this:

$ python -m mypy.exportjson .mypy_cache/.../my_module.data.ff

🚀 urllib3 is fundraising for HTTP/2 support

urllib3 is raising ~$40,000 USD to release HTTP/2 support and ensure long-term sustainable maintenance of the project after a sharp decline in financial support. If your company or organization uses Python and would benefit from HTTP/2 support in Requests, pip, cloud SDKs, and thousands of other projects please consider contributing financially to ensure HTTP/2 support is developed sustainably and maintained for the long-haul.

Thank you for your support.

Security

• Fixed a security issue where streaming API could improperly handle highly compressed HTTP content ("decompression bombs") leading to excessive resource consumption even when a small amount of data was requested. Reading small chunks of compressed data is safer and much more efficient now. (CVE-2025-66471 reported by @​Cycloctane, 8.9 High, GHSA-2xpw-w6gg-jr37)
• Fixed a security issue where an attacker could compose an HTTP response with virtually unlimited links in the Content-Encoding header, potentially leading to a denial of service (DoS) attack by exhausting system resources during decoding. The number of allowed chained encodings is now limited to 5. (CVE-2025-66418 reported by @​illia-v, 8.9 High, GHSA-gm62-xv2j-4w53)

[!IMPORTANT]

• If urllib3 is not installed with the optional urllib3[brotli] extra, but your environment contains a Brotli/brotlicffi/brotlipy package anyway, make sure to upgrade it to at least Brotli 1.2.0 or brotlicffi 1.2.0.0 to benefit from the security fixes and avoid warnings. Prefer using urllib3[brotli] to install a compatible Brotli package automatically.
• If you use custom decompressors, please make sure to update them to respect the changed API of urllib3.response.ContentDecoder.

Features

• Enabled retrieval, deletion, and membership testing in HTTPHeaderDict using bytes keys. (#3653)
• Added host and port information to string representations of HTTPConnection. (#3666)
• Added support for Python 3.14 free-threading builds explicitly. (#3696)

Removals

• Removed the HTTPResponse.getheaders() method in favor of HTTPResponse.headers. Removed the HTTPResponse.getheader(name, default) method in favor of HTTPResponse.headers.get(name, default). (#3622)

Bugfixes

• Fixed redirect handling in urllib3.PoolManager when an integer is passed for the retries parameter. (#3649)
• Fixed HTTPConnectionPool when used in Emscripten with no explicit port. (#3664)
• Fixed handling of SSLKEYLOGFILE with expandable variables. (#3700)

Misc

• Changed the zstd extra to install backports.zstd instead of zstandard on Python 3.13 and before. (#3693)
• Improved the performance of content decoding by optimizing BytesQueueBuffer class. (#3710)
• Allowed building the urllib3 package with newer setuptools-scm v9.x. (#3652)
• Ensured successful urllib3 builds by setting Hatchling requirement to ≥ 1.27.0. (#3638)

v2.12.5 2025-11-26

v2.12.5 (2025-11-26)

This is the fifth 2.12 patch release, addressing an issue with the MISSING sentinel and providing several documentation improvements.

The next 2.13 minor release will be published in a couple weeks, and will include a new polymorphic serialization feature addressing the remaining unexpected changes to the serialize as any behavior.

• Fix pickle error when using model_construct() on a model with MISSING as a default value by @​ornariece in #12522.
• Several updates to the documentation by @​Viicos.

v2.12.4 2025-11-05

v2.12.4 (2025-11-05)

This is the fourth 2.12 patch release, fixing more regressions, and reverting a change in the build() method of the AnyUrl and Dsn types.

This patch release also fixes an issue with the serialization of IP address types, when serialize_as_any is used. The next patch release will try to address the remaining issues with serialize as any behavior by introducing a new polymorphic serialization feature, that should be used in most cases in place of serialize as any.

• Fix issue with forward references in parent TypedDict classes by @​Viicos in #12427.

  This issue is only relevant on Python 3.14 and greater.

• Exclude fields with exclude_if from JSON Schema required fields by @​Viicos in #12430

• Revert URL percent-encoding of credentials in the build() method of the AnyUrl and Dsn types by @​davidhewitt in pydantic-core#1833.

  This was initially considered as a bugfix, but caused regressions and as such was fully reverted. The next release will include an opt-in option to percent-encode components of the URL.

• Add type inference for IP address types by @​davidhewitt in pydantic-core#1868.

  The 2.12 changes to the serialize_as_any behavior made it so that IP address types could not properly serialize to JSON.

• Avoid getting default values from defaultdict by @​davidhewitt in pydantic-core#1853.

  This fixes a subtle regression in the validation behavior of the collections.defaultdict type.

• Fix issue with field serializers on nested typed dictionaries by @​davidhewitt in pydantic-core#1879.

• Add more pydantic-core builds for the three-threaded version of Python 3.14 by @​davidhewitt in pydantic-core#1864.
