Release notes

Sourced from coverage's releases.

7.15.4

Version 7.15.4 — 2026-08-06

• Fix: in the HTML report, a source file name containing a double quote (legal on POSIX) wasn’t escaped where it’s dropped into the href of the index and prev/next links, so it could close the attribute early and inject markup. Page URLs are now escaped. Thanks, Rajath Mohare.
• Fix: the LCOV report wrote file names and other fields into its line-oriented records without neutralizing control characters. A measured file whose name contained a newline (legal on POSIX) could forge extra records, inflating the coverage seen by tools that read the report. Control characters in a field are now replaced. Thanks, Rajath Mohare.
• Wheels are now provided for Python 3.15.

7.15.3

Version 7.15.3 — 2026-08-02

• Fix: the sysmon core is incompatible with dynamic contexts. Previously, the combination would be prevented when read from the coverage.py configuration. But using the context API as pytest-cov does, contexts would be silently dropped. Now a warning is issued, thanks to Jisang Han. Closes issue 2200.
• A performance improvement in the low-level line number bookkeeping when combining data files, thanks to Kevin Turcios.
• Performance improvement in HTML reporting by reducing the number of times files have to be parsed, thanks to Kevin Turcios.

7.15.2

Version 7.15.2 — 2026-07-15

• Fix: one of the performance improvements in 7.15.1 (pull 2215) dramatically increased memory use during reporting for large projects. Now we use a different approach that is both faster and slimmer than 7.15.0. Fixes issue 2229.

7.15.1

Version 7.15.1 — 2026-07-12

• Fix: in the HTML report with show_contexts enabled, a context label containing </script> (for example a parametrized pytest node id) could close the inline <script> element in a file page early, injecting markup. Context labels are now fully escaped. Thanks, Rajath Mohare.
• A number of performance improvements thanks to Paul Kehrer, in pull requests 2213, 2214, 2215, 2216, 2218, 2220, and 2221.

7.15.0

Version 7.15.0 — 2026-07-02

• Since 7.14.0, reporting commands implicitly combine parallel data files. Now those commands have a new option --keep-combined to retain the data files after combining them instead of the default, which is to delete them. Finishes issue 2198.
• Fix: the LCOV report would incorrectly count excluded functions as uncovered, as described in issue 2205. This is now fixed thanks to Martin Kuntz Jacobsen.
• When running your program, coverage now correctly sets yourmodule.__spec__.loader as strongly recommended, avoiding the deprecation warning described in issue 2208. Thanks, A5rocks.
• Fix: with Python 3.10, running with the -I (isolated mode) option didn’t correctly omit the current directory from the module search path, as described in issue 2103. That is now fixed thanks to Ilia Sorokin.

Updates mypy from 1.16.1 to 2.3.1

Changelog

Sourced from mypy's changelog.

Mypy 2.3.1

• Fix mypyc crash on double yielding Iterators (Daniël van Noord, PR 21826)
• Fix mypyc default_factory for inherited dataclass (Daniël van Noord, PR 21785)
• Clear mypyc coroutine env on coroutine completion (Piotr Sawicki, PR 21734)
• Fix crash when unpacking return value from overload (Shantanu, PR 21830)

Mypy 2.2

We've just uploaded mypy 2.2.0 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.

Support for Closed TypedDicts (PEP 728)

Mypy now supports closed TypedDicts as specified in PEP 728. A closed TypedDict cannot have extra keys beyond those explicitly defined. This allows the type checker to determine that certain operations are safe when they otherwise wouldn't be due to the potential presence of unknown keys.

You can use the closed keyword argument with TypedDict:

HasName = TypedDict("HasName", {"name": str})
HasOnlyName = TypedDict("HasOnlyName", {"name": str}, closed=True)
Movie = TypedDict("Movie", {"name": str, "year": int})
movie: Movie = {"name": "Nimona", "year": 2023}
has_name: HasName = movie  # OK: HasName is open (default)
has_only_name: HasOnlyName = movie  # Error: HasOnlyName is closed and Movie has extra "year" key
</tr></table>

Updates pytest from 8.4.1 to 9.1.1

Release notes

Sourced from pytest's releases.

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.
