+
+## 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)
+
+### Performance
+
+- Store raw tuples instead of NamedTuples in Black's cache, improving performance and
+ decreasing the size of the cache (#3877)
+
+## 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
+
+- Black now applies exclusion and ignore logic before resolving symlinks (#3846)
+
+### Performance
+
+- Avoid importing `IPython` if notebook cells do not contain magics (#3782)
+- Improve caching by comparing file hashes as fallback for mtime and size (#3821)
+
+### _Blackd_
+
+- Fix an issue in `blackd` with single character input (#3558)
+
+### Integrations
+
+- Black now has an
+ [official pre-commit mirror](https://github.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)
+- The `.black.env` folder specified by `ENV_PATH` will now be removed on the completion
+ of the GitHub Action (#3759)
+
+## 23.7.0

environment variable (#3743)
- `.pytest_cache`, `.ruff_cache` and `.vscode` are now excluded by default (#3691)
-- Fix black not honouring `pyproject.toml` settings when running `--stdin-filename` 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
+- Fix _Black_ not honouring `pyproject.toml` settings when running `--stdin-filename`
+ 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)
