[Compare Source](https://togithub.com/psf/black/compare/23.12.0...23.12.1)
##### Packaging
- Fixed a bug that included dependencies from the `d` extra by default ([#4108](https://togithub.com/psf/black/issues/4108))
### [`v23.12.0`](https://togithub.com/psf/black/blob/HEAD/CHANGES.md#23120)
[Compare Source](https://togithub.com/psf/black/compare/23.11.0...23.12.0)
##### Highlights
It's almost 2024, which means it's time for a new edition of *Black*'s stable style!
Together with this release, we'll put out an alpha release 24.1a1 showcasing the draft
2024 stable style, which we'll finalize in the January release. Please try it out and
[share your feedback](https://togithub.com/psf/black/issues/4042).
This release (23.12.0) will still produce the 2023 style. Most but not all of the
changes in `--preview` mode will be in the 2024 stable style.
##### Stable style
- Fix bug where `# fmt: off` automatically dedents when used with the `--line-ranges`
option, even when it is not within the specified line range. ([#4084](https://togithub.com/psf/black/issues/4084))
- Fix feature detection for parenthesized context managers ([#4104](https://togithub.com/psf/black/issues/4104))
##### Preview style
- Prefer more equal signs before a break when splitting chained assignments ([#4010](https://togithub.com/psf/black/issues/4010))
- Standalone form feed characters at the module level are no longer removed ([#4021](https://togithub.com/psf/black/issues/4021))
- Additional cases of immediately nested tuples, lists, and dictionaries are now
indented less ([#4012](https://togithub.com/psf/black/issues/4012))
- Allow empty lines at the beginning of all blocks, except immediately before a
docstring ([#4060](https://togithub.com/psf/black/issues/4060))

functions or class definitions ([#4066](https://togithub.com/psf/black/issues/4066)) ([#4103](https://togithub.com/psf/black/issues/4103))
##### Configuration
- `--line-ranges` now skips *Black*'s internal stability check in `--safe` mode. This
avoids a crash on rare inputs that have many unformatted same-content lines. ([#4034](https://togithub.com/psf/black/issues/4034))
##### Packaging
- Upgrade to mypy 1.7.1 ([#4049](https://togithub.com/psf/black/issues/4049)) ([#4069](https://togithub.com/psf/black/issues/4069))

### [`v23.9.1`](https://togithub.com/psf/black/blob/HEAD/CHANGES.md#2391)
[Compare Source](https://togithub.com/psf/black/compare/23.9.0...23.9.1)
Due to various issues, the previous release (23.9.0) did not include compiled mypyc
wheels, which make Black significantly faster. These issues have now been fixed, and
this release should come with compiled wheels once again.
There will be no wheels for Python 3.12 due to a bug in mypyc. We will provide 3.12
wheels in a future release as soon as the mypyc bug is fixed.
##### Packaging
- Upgrade to mypy 1.5.1 ([#3864](https://togithub.com/psf/black/issues/3864))
##### Performance

decreasing the size of the cache ([#3877](https://togithub.com/psf/black/issues/3877))
### [`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

[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 ([#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 ([#3759](https://togithub.com/psf/black/issues/3759))

PEP 604 unions ([#3735](https://togithub.com/psf/black/issues/3735))
- Fix several bugs and crashes where comments in stub files were removed or mishandled
under some circumstances ([#3745](https://togithub.com/psf/black/issues/3745))

- *Black* will now error if `exclude` and `extend-exclude` have invalid data types in
`pyproject.toml`, instead of silently doing the wrong thing ([#3764](https://togithub.com/psf/black/issues/3764))
##### Packaging
- Upgrade mypyc from 0.991 to 1.3 ([#3697](https://togithub.com/psf/black/issues/3697))
- Remove patching of Click that mitigated errors on Python 3.6 with `LANG=C` ([#3768](https://togithub.com/psf/black/issues/3768))
##### Parser

### [`v23.3.0`](https://togithub.com/psf/black/blob/HEAD/CHANGES.md#2330)
[Compare Source](https://togithub.com/psf/black/compare/23.1.0...23.3.0)
##### Highlights
This release fixes a longstanding confusing behavior in Black's GitHub action, where the
version of the action did not determine the version of Black being run (issue [#3382](https://togithub.com/psf/black/issues/3382)). In
addition, there is a small bug fix around imports and a number of improvements to the
preview style.
Please try out the
[preview style](https://black.readthedocs.io/en/stable/the_black_code_style/future_style.html#preview-style)
with `black --preview` and tell us your feedback. All changes in the preview style are
expected to become part of Black's stable style in January 2024.
##### Stable style
- Import lines with `# fmt: skip` and `# fmt: off` no longer have an extra blank line
added when they are right after another import line ([#3610](https://togithub.com/psf/black/issues/3610))
##### Preview style
- Add trailing commas to collection literals even if there's a comment after the last
entry ([#3393](https://togithub.com/psf/black/issues/3393))

compared to their non-async version. ([#3609](https://togithub.com/psf/black/issues/3609))
- `with` statements that contain two context managers will be consistently wrapped in
parentheses ([#3589](https://togithub.com/psf/black/issues/3589))
- Let string splitters respect [East Asian Width](https://www.unicode.org/reports/tr11/)
([#3445](https://togithub.com/psf/black/issues/3445))
- Now long string literals can be split after East Asian commas and periods (`、` U+3001
IDEOGRAPHIC COMMA, `。` U+3002 IDEOGRAPHIC FULL STOP, & `，` U+FF0C FULLWIDTH COMMA)
besides before spaces ([#3445](https://togithub.com/psf/black/issues/3445))
- For stubs, enforce one blank line after a nested class with a body other than just
`...` ([#3564](https://togithub.com/psf/black/issues/3564))
- Improve handling of multiline strings by changing line split behavior ([#1879](https://togithub.com/psf/black/issues/1879))
##### Parser
- Added support for formatting files with invalid type comments ([#3594](https://togithub.com/psf/black/issues/3594))
##### Integrations
- Update GitHub Action to use the version of Black equivalent to action's version if
version input is not specified ([#3543](https://togithub.com/psf/black/issues/3543))
- Fix missing Python binary path in autoload script for vim ([#3508](https://togithub.com/psf/black/issues/3508))
##### Documentation
