### Release Notes

<details>
<summary>psf/black (black)</summary>

### [`v25.12.0`](https://github.com/psf/black/blob/HEAD/CHANGES.md#25120)

[Compare Source](psf/black@25.11.0...25.12.0)

##### Highlights

- Black no longer supports running with Python 3.9 ([#&#8203;4842](psf/black#4842))

##### Stable style

- Fix bug where comments preceding `# fmt: off`/`# fmt: on` blocks were incorrectly
  removed, particularly affecting Jupytext's `# %% [markdown]` comments ([#&#8203;4845](psf/black#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 ([#&#8203;4872](psf/black#4872))
- Fix possible crash when `fmt: ` directives aren't on the top level ([#&#8203;4856](psf/black#4856))

##### Preview style

- Fix `fmt: skip` skipping the line after instead of the line it's on ([#&#8203;4855](psf/black#4855))
- Remove unnecessary parentheses from the left-hand side of assignments while preserving
  magic trailing commas and intentional multiline formatting ([#&#8203;4865](psf/black#4865))
- Fix `fix_fmt_skip_in_one_liners` crashing on `with` statements ([#&#8203;4853](psf/black#4853))
- Fix `fix_fmt_skip_in_one_liners` crashing on annotated parameters ([#&#8203;4854](psf/black#4854))
- Fix new lines being added after imports with `# fmt: skip` on them ([#&#8203;4894](psf/black#4894))

##### Packaging

- Releases now include arm64 Windows binaries and wheels ([#&#8203;4814](psf/black#4814))

##### Integrations

- Add `output-file` input to GitHub Action `psf/black` to write formatter output to a
  file for artifact capture and log cleanliness ([#&#8203;4824](psf/black#4824))
