Version 26.5.1

Stable style

• Fix unstable formatting of annotated assignments whose subscript annotation contains an inline comment (e.g. x: list[ # pyright: ignore[...]) (#5130)
• Preserve inline comments (including # type: ignore) immediately before a # fmt: skip line, avoiding AST equivalence failures (#5139)

Packaging

• Correct the version in the published executables (#5137)

Documentation

• Add Neovim integration guide covering conform.nvim, ALE, and simple command approaches (#5124)

Version 26.5.0

Highlights

• Add support for unpacking in comprehensions (PEP 798) and for lazy imports (PEP 810), both new syntactic features in Python 3.15 (#5048)
• Python 3.15 is now supported. Compiled wheels are not yet provided for Python 3.15, so performance may be slower than on existing Python versions. Wheels will be provided once Python 3.15 is later in its release cycle. (#5127)

Stable style

• Fix # fmt: skip being ignored in nested if expressions with parenthesized in clauses (#4903)
• Add syntactic support for Python 3.15 (#5048)
• Fix crash when an f-string follows a # fmt: off comment inside brackets (#5097)
• Preserve multiline compound statement headers when # fmt: skip is placed on the colon line (#5117)

Preview style

• Improve heuristics around whether blank lines should appear before, within and after groups of same-name decorated functions (such as @overload groups) in .pyi stub files (#5021)
• Fix blank lines being removed between a function and a decorated class in .pyi stub files (#5092)
• Prevent string merger from creating unsplittable long lines when a pragma comment (e.g. # type: ignore) follows the closing bracket (#5096)

Packaging

• Run CI on 3.15 (#5127)

Mypy Release Notes

Next Release

Mypy 2.1

We’ve just uploaded mypy 2.1.0 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.

librt.vecs: Fast Growable Array Type for Mypyc

The new librt.vecs module provides an efficient growable array type vec that is optimized for mypyc use. It provides fast, packed arrays with integer and floating point value types, which can be several times faster than list, and tens of times faster than array.array in code compiled using mypyc. It also supports nested vec objects and non-value-type items, such as vec[vec[str]].

Refer to the documentation for the details.

Contributed by Jukka Lehtosalo.

librt.random: Fast Pseudo-Random Number Generation

The new librt.random module provides fast pseudo-random number generation that is optimized for code compiled using mypyc. It can be 3x to 10x faster than the stdlib random module in compiled code.

Refer to the documentation for the details.

Contributed by Jukka Lehtosalo (PR 21433).

Mypyc Improvements

• Enable incremental self-compilation (Vaggelis Danias, PR 21369)
• Make compilation order with multiple files consistent (Piotr Sawicki, PR 21419)
• Fix crash on accessing StopAsyncIteration (Piotr Sawicki, PR 21406)
• Fix incremental compilation with separate flag (Vaggelis Danias, PR 21299)

Fixes to Crashes

• Fix crash on partial type with --allow-redefinition and global declaration (Jukka Lehtosalo, PR 21428)
• Fix broken awaitable generator patching (Ivan Levkivskyi, PR 21435)

7.1.0 (2026-03-21)

• Fixed total coverage computation to always be consistent, regardless of reporting settings. Previously some reports could produce different total counts, and consequently can make --cov-fail-under behave different depending on reporting options. See [#641](https://github.com/pytest-dev/pytest-cov/issues/641) <https://github.com/pytest-dev/pytest-cov/issues/641>_.

• Improve handling of ResourceWarning from sqlite3.

  The plugin adds warning filter for sqlite3 ResourceWarning unclosed database (since 6.2.0). It checks if there is already existing plugin for this message by comparing filter regular expression. When filter is specified on command line the message is escaped and does not match an expected message. A check for an escaped regular expression is added to handle this case.

  With this fix one can suppress ResourceWarning from sqlite3 from command line::

  pytest -W "ignore:unclosed database in <sqlite3.Connection object at:ResourceWarning" ...

• Various improvements to documentation. Contributed by Art Pelling in [#718](https://github.com/pytest-dev/pytest-cov/issues/718) <https://github.com/pytest-dev/pytest-cov/pull/718>_ and "vivodi" in [#738](https://github.com/pytest-dev/pytest-cov/issues/738) <https://github.com/pytest-dev/pytest-cov/pull/738>. Also closed [#736](https://github.com/pytest-dev/pytest-cov/issues/736) <https://github.com/pytest-dev/pytest-cov/issues/736>.

• Fixed some assertions in tests. Contributed by in Markéta Machová in [#722](https://github.com/pytest-dev/pytest-cov/issues/722) <https://github.com/pytest-dev/pytest-cov/pull/722>_.

• Removed unnecessary coverage configuration copying (meant as a backup because reporting commands had configuration side-effects before coverage 5.0).

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.

Version 7.14.1 — 2026-05-26

• Fix: the HTML report used typographic niceties to make file paths more readable by adding a small amount of space around slashes. Those spaces interfered with searching the page for file paths of interest. Now the report uses CSS to accomplish the same visual tweak so that searches with slashes work correctly. Closes issue 2170_.

• Add a 3.16 PyPI classifier <hugo-316_>_ since we test on the 3.16 main branch.

Version 7.14.0 — 2026-05-10

• Feature: now when running one of the reporting commands, if there are parallel data files that need combining, they will be implicitly combined before creating the report. There is no option to avoid the combination; let us know if you have a use case that requires it. Thanks, Tim Hatch <pull 2162_>. Closes issue 1781.

• Fix: the output from combine was too verbose, listing each file considered. Now it shows a single line with the counts of files combined, files skipped, and files with errors. The -q flag suppresses this line. The old detailed lines are available with the new --debug=combine option.

• Fix: running a Python file through a symlink now sets the sys.path correctly, matching regular Python behavior. Fixes issue 2157_.

• Fix: Collector.flush_data could fail with "RuntimeError: Set changed size during iteration" when a tracer in another thread added a line to the per-file set that add_lines (or add_arcs) was iterating. The values passed to CoverageData are now snapshotted via dict.copy() and set.copy(), which are atomic under the GIL. Thanks, Alex Vandiver <pull 2165_>_.

• Fix: the soft keyword lazy is now bolded in HTML reports.

• We are no longer testing eventlet support. Eventlet started issuing stern deprecation warnings that break our tests. Our support code is still there.
