-
-## 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.

-## 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)

-- 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
-

- 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.
-
