Release Notes

psf/black (black)

v25.12.0

Compare Source

Highlights

• Black no longer supports running with Python 3.9 (#​4842)

Stable style

• Fix bug where comments preceding # fmt: off/# fmt: on blocks were incorrectly
  removed, particularly affecting Jupytext's # %% [markdown] comments (#​4845)
• Fix crash when multiple # fmt: skip comments are used in a multi-part if-clause, on
  string literals, or on dictionary entries with long lines (#​4872)
• Fix possible crash when fmt: directives aren't on the top level (#​4856)

Preview style

• Fix fmt: skip skipping the line after instead of the line it's on (#​4855)
• Remove unnecessary parentheses from the left-hand side of assignments while preserving
  magic trailing commas and intentional multiline formatting (#​4865)
• Fix fix_fmt_skip_in_one_liners crashing on with statements (#​4853)
• Fix fix_fmt_skip_in_one_liners crashing on annotated parameters (#​4854)
• Fix new lines being added after imports with # fmt: skip on them (#​4894)

Packaging

• Releases now include arm64 Windows binaries and wheels (#​4814)

Integrations

• Add output-file input to GitHub Action psf/black to write formatter output to a
  file for artifact capture and log cleanliness (#​4824)

coveragepy/coveragepy (coverage)

v7.13.0

Compare Source

• Feature: coverage.py now supports :file:.coveragerc.toml configuration
  files. These files use TOML syntax and take priority over
  :file:pyproject.toml but lower priority than :file:.coveragerc files.
  Closes issue 1643_ thanks to Olena Yefymenko <pull 1952_>_.

• Fix: we now include a permanent .pth file which is installed with the code,
  fixing issue 2084. In 7.12.1b1 this was done incorrectly: it didn't work
  when using the source wheel (py3-none-any). This is now fixed. Thanks,
  Henry Schreiner <pull 2100_>.

• Deprecated: when coverage.py is installed, it creates three command entry
  points: coverage, coverage3, and coverage-3.10 (if installed for
  Python 3.10). The second and third of these are not needed and will
  eventually be removed. They still work for now, but print a message about
  their deprecation.
