+## 23.9.0
+
+### Preview style
+
+- More concise formatting for dummy implementations (#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 (#3862)
+- Fix a bug whereby spaces were removed from walrus operators within subscript(#3823)
+
+### Configuration

+ your `.pre-commit-config.yaml` will make Black about 2x faster (#3828)
+- The `.black.env` folder specified by `ENV_PATH` will now be removed on the completion
+ of the GitHub Action (#3759)
+
+## 23.7.0

+ (#3773)
+
+### Preview style
+
+- Implicitly concatenated strings used as function args are no longer wrapped inside
+ parentheses (#3640)
+- Remove blank lines between a class definition and its docstring (#3692)
+
+### Configuration
+
+- The `--workers` argument to _Black_ can now be specified via the `BLACK_NUM_WORKERS`

+ and the `pyproject.toml` found isn't in the current working directory (#3719)
+- _Black_ will now error if `exclude` and `extend-exclude` have invalid data types in
+ `pyproject.toml`, instead of silently doing the wrong thing (#3764)
+
+### Packaging
+
+- Upgrade mypyc from 0.991 to 1.3 (#3697)
+- Remove patching of Click that mitigated errors on Python 3.6 with `LANG=C` (#3768)

+ (#3763)
+- Update GitHub Action to display black output in the job summary (#3688)
+
+### Documentation
+
+- Add a CITATION.cff file to the root of the repository, containing metadata on how to
+ cite this software (#3723)
+- Update the _classes_ and _exceptions_ documentation in Developer reference to match
+ the latest code base (#3755)
+
+## 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). 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)
+
+### Preview style
+
+- Add trailing commas to collection literals even if there's a comment after the last
+ entry (#3393)
+- `async def`, `async for`, and `async with` statements are now formatted consistently
+ compared to their non-async version. (#3609)
+- `with` statements that contain two context managers will be consistently wrapped in
+ parentheses (#3589)
+- Let string splitters respect [East Asian Width](https://www.unicode.org/reports/tr11/)
+ (#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)
+- For stubs, enforce one blank line after a nested class with a body other than just
+ `...` (#3564)
+- Improve handling of multiline strings by changing line split behavior (#1879)
+
+### Parser
+
+- Added support for formatting files with invalid type comments (#3594)
+
+### Integrations
+
+- Update GitHub Action to use the version of Black equivalent to action's version if
+ version input is not specified (#3543)
+- Fix missing Python binary path in autoload script for vim (#3508)
+
+### Documentation
+
+- Document that only the most recent release is supported for security issues;
+ vulnerabilities should be reported through Tidelift (#3612)
+
+## 23.1.0
+
+### Highlights
+
+This is the first release of 2023, and following our
+[stability policy](https://black.readthedocs.io/en/stable/the_black_code_style/index.html#stability-policy),
+it comes with a number of improvements to our stable style, including improvements to
+empty line handling, removal of redundant parentheses in several contexts, and output
+that highlights implicitly concatenated strings better.
+
+There are also many changes to the preview style; try out `black --preview` and give us
+feedback to help us set the stable style for next year.
+
+In addition to style changes, Black now automatically infers the supported Python
+versions from your `pyproject.toml` file, removing the need to set Black's target
+versions separately.
+
+### Stable style
+
+<!-- Changes that affect Black's stable style -->
+
+- Introduce the 2023 stable style, which incorporates most aspects of last year's
+ preview style (#3418). Specific changes:
+ - Enforce empty lines before classes and functions with sticky leading comments
+ (#3302) (22.12.0)
+ - Reformat empty and whitespace-only files as either an empty file (if no newline is
+ present) or as a single newline character (if a newline is present) (#3348)
+ (22.12.0)
+ - Implicitly concatenated strings used as function args are now wrapped inside
+ parentheses (#3307) (22.12.0)
+ - Correctly handle trailing commas that are inside a line's leading non-nested parens
+ (#3370) (22.12.0)
+ - `--skip-string-normalization` / `-S` now prevents docstring prefixes from being
+ normalized as expected (#3168) (since 22.8.0)
+ - When using `--skip-magic-trailing-comma` or `-C`, trailing commas are stripped from
+ subscript expressions with more than 1 element (#3209) (22.8.0)
+ - Implicitly concatenated strings inside a list, set, or tuple are now wrapped inside
+ parentheses (#3162) (22.8.0)
+ - Fix a string merging/split issue when a comment is present in the middle of
+ implicitly concatenated strings on its own line (#3227) (22.8.0)
+ - Docstring quotes are no longer moved if it would violate the line length limit
+ (#3044, #3430) (22.6.0)
+ - Parentheses around return annotations are now managed (#2990) (22.6.0)
+ - Remove unnecessary parentheses around awaited objects (#2991) (22.6.0)
+ - Remove unnecessary parentheses in `with` statements (#2926) (22.6.0)
+ - Remove trailing newlines after code block open (#3035) (22.6.0)
+ - Code cell separators `#%%` are now standardised to `# %%` (#2919) (22.3.0)
+ - Remove unnecessary parentheses from `except` statements (#2939) (22.3.0)

+
### Packaging
<!-- Changes to how Black is packaged, such as dependency requirements -->
- Upgrade mypyc from `0.971` to `0.991` so mypycified _Black_ can be built on armv7
(#3380)
+ - This also fixes some crashes while using compiled Black with a debug build of
+ CPython
- Drop specific support for the `tomli` requirement on 3.11 alpha releases, working
around a bug that would cause the requirement not to be installed on any non-final
Python releases (#3448)

-### Parser
-
-<!-- Changes to the parser or to version autodetection -->
-
-### Performance
-
-<!-- Changes that improve Black's performance. -->

+ functionality that needs to parse part of the project metadata (#3219)
### Output
<!-- Changes to Black's terminal output and error messages -->
+- Calling `black --help` multiple times will return the same help contents each time
+ (#3516)
