### pytest 9.0.3 (2026-04-07)

#### Bug fixes

-
[#&#8203;12444](https://redirect.github.com/pytest-dev/pytest/issues/12444):
Fixed `pytest.approx` which now correctly takes into account
`~collections.abc.Mapping` keys order to compare them.

-
[#&#8203;13634](https://redirect.github.com/pytest-dev/pytest/issues/13634):
Blocking a `conftest.py` file using the `-p no:` option is now
explicitly disallowed.

Previously this resulted in an internal assertion failure during plugin
loading.

Pytest now raises a clear `UsageError` explaining that conftest files
are not plugins and cannot be disabled via `-p`.

-
[#&#8203;13734](https://redirect.github.com/pytest-dev/pytest/issues/13734):
Fixed crash when a test raises an exceptiongroup with `__tracebackhide__
= True`.

-
[#&#8203;14195](https://redirect.github.com/pytest-dev/pytest/issues/14195):
Fixed an issue where non-string messages passed to <span
class="title-ref">unittest.TestCase.subTest()</span> were not printed.

-
[#&#8203;14343](https://redirect.github.com/pytest-dev/pytest/issues/14343):
Fixed use of insecure temporary directory (CVE-2025-71176).

#### Improved documentation

-
[#&#8203;13388](https://redirect.github.com/pytest-dev/pytest/issues/13388):
Clarified documentation for `-p` vs `PYTEST_PLUGINS` plugin loading and
fixed an incorrect `-p` example.
-
[#&#8203;13731](https://redirect.github.com/pytest-dev/pytest/issues/13731):
Clarified that capture fixtures (e.g. `capsys` and `capfd`) take
precedence over the `-s` / `--capture=no` command-line options in
`Accessing captured output from a test function
<accessing-captured-output>`.
-
[#&#8203;14088](https://redirect.github.com/pytest-dev/pytest/issues/14088):
Clarified that the default `pytest_collection` hook sets `session.items`
before it calls `pytest_collection_finish`, not after.
-
[#&#8203;14255](https://redirect.github.com/pytest-dev/pytest/issues/14255):
TOML integer log levels must be quoted: Updating reference
documentation.

#### Contributor-facing changes

-
[#&#8203;12689](https://redirect.github.com/pytest-dev/pytest/issues/12689):
The test reports are now published to Codecov from GitHub Actions.
The test statistics is visible [on the web
interface](https://app.codecov.io/gh/pytest-dev/pytest/tests).
