##### Highlights

-   Black no longer supports running with Python 3.9 ([#&#8203;4842](https://redirect.github.com/psf/black/issues/4842))

##### Stable style

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

##### Preview style

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

##### Integrations

-   Add `output-file` input to GitHub Action `psf/black` to write formatter output to a
