### Release Notes

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

###
[`v23.9.0`](https://togithub.com/psf/black/blob/HEAD/CHANGES.md#2390)

[Compare Source](https://togithub.com/psf/black/compare/23.7.0...23.9.0)

##### Preview style

- More concise formatting for dummy implementations
([#&#8203;3796](https://togithub.com/psf/black/issues/3796))
- In stub files, add a blank line between a statement with a body (e.g
an
`if sys.version_info > (3, x):`) and a function definition on the same
level ([#&#8203;3862](https://togithub.com/psf/black/issues/3862))
- Fix a bug whereby spaces were removed from walrus operators within
subscript([#&#8203;3823](https://togithub.com/psf/black/issues/3823))

##### Configuration

- Black now applies exclusion and ignore logic before resolving symlinks
([#&#8203;3846](https://togithub.com/psf/black/issues/3846))

##### Performance

- Avoid importing `IPython` if notebook cells do not contain magics
([#&#8203;3782](https://togithub.com/psf/black/issues/3782))
- Improve caching by comparing file hashes as fallback for mtime and
size ([#&#8203;3821](https://togithub.com/psf/black/issues/3821))

##### *Blackd*

- Fix an issue in `blackd` with single character input
([#&#8203;3558](https://togithub.com/psf/black/issues/3558))

##### Integrations

-   Black now has an
[official pre-commit
mirror](https://togithub.com/psf/black-pre-commit-mirror). Swapping
`https://github.com/psf/black` to
`https://github.com/psf/black-pre-commit-mirror` in
your `.pre-commit-config.yaml` will make Black about 2x faster
([#&#8203;3828](https://togithub.com/psf/black/issues/3828))
- The `.black.env` folder specified by `ENV_PATH` will now be removed on
the completion
of the GitHub Action
([#&#8203;3759](https://togithub.com/psf/black/issues/3759))
