7.16.0

Version 7.16.0 — 2026-08-28

• When combining files, now path separator slashes will automatically be converted to the local file system style. This makes it less necessary to define [paths] configuration to combine data across operating systems. Fixes issue 2266.
• The Coverage.switch_context() method now returns the previous context.
• Fix: previously, a [paths] pattern would be replaced everywhere in a file path when it was only meant to be replaced once, in the leading portion of the path. This is now fixed, in pull 2268.
• Fixes to validation of options and configuration settings:
  • Negative precision settings now always cause useful error messages (pull 2261).
  • An invalid regex in the --contexts option (or the [report] contexts setting) reported a confusing “Couldn’t use data file …: user-defined function raised exception” error. Now it raises a proper configuration error naming the bad regex, like other regex settings do (pull 2262).
  • Non-string values in TOML configuration settings now produce a helpful error message instead of a traceback. This affects list settings whose elements aren’t strings (like omit, exclude_lines, or a [paths] entry), file settings like data_file, and any wrong-typed value in the [paths] section (pull 2263).
  • coverage run refuses run-affecting command-line options like --branch alongside --concurrency=multiprocessing, since they can’t reach the subprocesses. The check only recognized multiprocessing as the entire option value, so --concurrency=multiprocessing,thread slipped through and failed later with “Can’t combine statement coverage data with branch data”. Each named concurrency library is now properly considered (pull 2270).
• Fix: coverage annotate -d DIR raised an AssertionError if any measured file had an extension other than .py, such as a .pyw file on Windows. The original extension is now restored on the annotated copy (pull 2265).

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.

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

Updates packaging from 26.2 to 26.3

Release notes

Sourced from packaging's releases.

26.3

What's Changed

Features

• Add a public VersionRange API and SpecifierSet.to_range(), representing the versions a specifier set accepts as an interval set that supports intersection, union, difference, complement, set relations, membership tests, and filtering. VersionRange.to_specifier_set() converts a range back to a SpecifierSet where a PEP 440 form exists. (#1267, #1270, #1298)
• PEP 808: accept Metadata-Version: 2.6. (#1194)
• Add a limit argument to parse_tag() for compressed tag sets. (#1220)
• Add a prefer_sdist_predicate argument to Pylock.select() to prefer source distributions over wheels for selected packages. (#1334)
• Add pure_python_tags() to generate the pure-Python tags for a Python version without touching the running platform. (#1346)
• Add SpecifierSet.is_subset(), SpecifierSet.is_superset(), and SpecifierSet.is_disjoint(), which compare the versions two specifier sets accept. (#1313)

Behavior adaptations

• Drop support for Python 3.8; packaging now requires Python 3.9 or later. (#1157)
• Prefer native linux_* platform tags over manylinux and musllinux tags on Linux. (#160)

Fixes for versions and specifiers

• Raise InvalidVersion instead of TypeError when Version is given a non-string. (#1319)
• Raise InvalidVersion for non-string pre-release letters passed to Version.from_parts. (#1241)
• Fix an AttributeError when hashing internally trimmed versions. (#1242)
• Fix SpecifierSet.is_unsatisfiable for post-release boundary intersections. (#1257)

Fixes for requirements and markers

• Make Requirement.__hash__ consistent with __eq__ for trailing-zero-equivalent specifiers (e.g. foo==1.0.0 and foo==1.0.0.0), so equal requirements hash equal and deduplicate in sets and dicts. (#1232)
• Normalize requested extra names before comparing or hashing requirements. (#644)
• Preserve a Requirement's specifier prereleases override across a pickle round trip. (#1204)
• Raise InvalidRequirement instead of InvalidSpecifier when a requirement contains an invalid specifier. (#1332)
• Clarify the error for post-release prefix wildcards like ==1.0.post1.*. (#1299)
• Preserve quoting semantics when serializing marker values, so round-tripped markers parse back to the same marker. (#1213)
• Keep the parentheses of a nested group when serializing markers. (#1316)
• Normalize extra and dependency_groups values in nested markers at parse time. (#1246, #1310)
• Raise UndefinedComparison when a set-valued variable like extras is used outside the membership form. (#1265)
• Raise UndefinedEnvironmentName (a KeyError subclass) for missing environment keys during marker evaluation. (#1276)
• Wrap malformed string literal errors in InvalidMarker / InvalidRequirement instead of leaking a low-level error. (#1249)
• Reject requirements and markers with a trailing line break. (#1345)

Fixes for metadata and licenses

• Collect all from_email validation errors into one ExceptionGroup instead of raising the first. (#1268)
• Accept the UTF-8 charset case-insensitively in email payloads. (#1330)
• Reject malformed Description-Content-Type values. (#1329)
• Don't rewrite user values that contain {field} placeholders in error messages. (#1327)
• Route multipart email payloads to unparsed instead of asserting. (#1247)
• Make InvalidMetadata and CyclicDependencyGroup picklable. (#1328)
• Fold every line boundary str.splitlines recognizes when writing a header with RFC822Message. (#1356)

Updates pytest from 9.0.3 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.

Updates syrupy from 5.3.1 to 6.0.0

Release notes

Sourced from syrupy's releases.

v6.0.0

Syrupy 6.0.0

(2026-08-22)

Syrupy 6 focuses on better built-in serialization, clearer snapshot workflows, and large-suite performance. Please review the breaking changes before upgrading.

Most suites should not need significant snapshot updates on upgrade — the main exception is dataclass usage (see below). Syrupy v6 does not change the required Python version or other package dependencies. Support for Python 3.10 will instead be dropped in the next Syrupy major version (v7).

Breaking Changes

Built-in dataclass serialization (removed DataclassPlugin)

stdlib dataclasses are now serialized natively by the Amber serializer. The separate DataclassPlugin has been removed.

• If you used DataclassPlugin: remove imports and plugin wiring. Behavior should match what the plugin produced; no snapshot rewrite should be needed for the dataclass shape itself.
• If you did not use the plugin: dataclass snapshots may change from a repr-style string to structured Amber form (field-by-field). Re-run with --snapshot-update where those assertions fail.

Example of what to remove:

# Before (v5)
from syrupy.extensions.amber.dataclasses_plugin import DataclassPlugin
class MySerializer(AmberDataSerializer):
serializer_plugins = [DataclassPlugin, ...]

# After (v6) — dataclasses work with the default Amber extension
assert MyDataclass(...) == snapshot

Attrs and Pydantic models are unchanged and still need their serializer plugins. See the serializer plugins example.

(#1220, closes #1048)

JSON datetime.date snapshots

The JSON extension now serializes datetime.date as YYYY-MM-DD instead of a repr string. Existing JSON snapshots that contain dates will need an update.

(#1216, closes #1058)

path_value nested path replacement in default (literal) mode

path_value(..., regex=False) now correctly replaces values at nested paths such as user.token. Previously, the default-mode lookup missed escaped path keys, so nested values were left unchanged (and could leak into committed snapshots).
