Release Notes

coveragepy/coveragepy (coverage)

v7.13.4

Compare Source

• Fix: the third-party code fix in 7.13.3 required examining the parent
  directories where coverage was run. In the unusual situation that one of the
  parent directories is unreadable, a PermissionError would occur, as
  described in issue 2129_. This is now fixed.

• Fix: in test suites that change sys.path, coverage.py could fail with
  "RuntimeError: Set changed size during iteration" as described and fixed in
  pull 2130_. Thanks, Noah Fatsi.

• We now publish ppc64le wheels, thanks to Pankhudi Jain <pull 2121_>_.

v7.13.3

Compare Source

• Fix: in some situations, third-party code was measured when it shouldn't have
  been, slowing down test execution. This happened with layered virtual
  environments such as uv sometimes makes. The problem is fixed, closing issue 2082_. Now any directory on sys.path that is inside a virtualenv is
  considered third-party code.

astral-sh/ruff (ruff)

v0.15.0

Compare Source

Released on 2026-02-03.

Check out the blog post for a migration
guide and overview of the changes!

Breaking changes

• Ruff now formats your code according to the 2026 style guide. See the formatter section below or in the blog post for a detailed list of changes.

• The linter now supports block suppression comments. For example, to suppress N803 for all parameters in this function:

  # ruff: disable[N803]
  def foo(
      legacyArg1,
      legacyArg2,
      legacyArg3,
      legacyArg4,
  ): ...
  # ruff: enable[N803]

  See the documentation for more details.

• The ruff:alpine Docker image is now based on Alpine 3.23 (up from 3.21).

• The ruff:debian and ruff:debian-slim Docker images are now based on Debian 13 "Trixie" instead of Debian 12 "Bookworm."

• Binaries for the ppc64 (64-bit big-endian PowerPC) architecture are no longer included in our releases. It should still be possible to build Ruff manually for this platform, if needed.

• Ruff now resolves all extended configuration files before falling back on a default Python version.

Stabilization

The following rules have been stabilized and are no longer in preview:

• blocking-http-call-httpx-in-async-function
  (ASYNC212)
• blocking-path-method-in-async-function
  (ASYNC240)
• blocking-input-in-async-function
  (ASYNC250)
• map-without-explicit-strict
  (B912)
• if-exp-instead-of-or-operator
  (FURB110)
• single-item-membership-test
  (FURB171)
• missing-maxsplit-arg (PLC0207)
• unnecessary-lambda (PLW0108)
• unnecessary-empty-iterable-within-deque-call
  (RUF037)

• invalid-suppression-comment
  (RUF103)
• unmatched-suppression-comment
  (RUF104)

The following behaviors have been stabilized:

• The --output-format flag is now respected when running Ruff in --watch mode, and the full output format is now used by default, matching the regular CLI output.
• builtin-attribute-shadowing (A003) now detects the use of shadowed built-in names in additional contexts like decorators, default arguments, and other attribute definitions.
• duplicate-union-member (PYI016) now considers typing.Optional when searching for duplicate union members.
• split-static-string (SIM905) now offers an autofix when the maxsplit argument is provided, even without a sep argument.
• dict-get-with-none-default (SIM910) now applies to more types of key expressions.
• super-call-with-parameters (UP008) now has a safe fix when it will not delete comments.
• unnecessary-default-type-args (UP043) now applies to stub (.pyi) files on Python versions before 3.13.

  later (#​20768)
