+## 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

+ 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)

+ 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)

+ 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)

unnecessary parentheses around short values in dict literals are now removed; long
string lambda values are now wrapped in parentheses (#3440)

+ around a bug that would cause the requirement not to be installed on any non-final
+ Python releases (#3448)
+- Black now depends on `packaging` version `22.0` or later. This is required for new
+ functionality that needs to parse part of the project metadata (#3219)
