+## 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
+
+### Highlights
+
+- Runtime support for Python 3.7 has been removed. Formatting 3.7 code will still be
+ supported until further notice (#3765)
+
+### Stable style
+
- Fix a bug where an illegal trailing comma was added to return type annotations using
PEP 604 unions (#3735)
-- Fix a bug where multi-line open parenthesis magic comment like `type: ignore` were not
- correctly parsed (#3740)
+- Fix several bugs and crashes where comments in stub files were removed or mishandled
+ under some circumstances (#3745)
+- Fix a crash with multi-line magic comments like `type: ignore` within parentheses
+ (#3740)
+- Fix error in AST validation when _Black_ removes trailing whitespace in a type comment
+ (#3773)
### Preview style
-<!-- Changes that affect Black's 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
-<!-- Changes to how Black can be configured -->
-
-- The `--workers` argument to Black can now be specified via the `BLACK_NUM_WORKERS`
+- The `--workers` argument to _Black_ can now be specified via the `BLACK_NUM_WORKERS`
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)
+- 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)
### Packaging
-<!-- Changes to how Black is packaged, such as dependency requirements -->
-
- Upgrade mypyc from 0.991 to 1.3 (#3697)

-<!-- Changes that improve Black's performance. -->
-
+- Speed up _Black_ significantly when the cache is full (#3751)
- Avoid importing `IPython` in a case where we wouldn't need it (#3748)
### Output
-<!-- Changes to Black's terminal output and error messages -->
-
- Use aware UTC datetimes internally, avoids deprecation warning on Python 3.12 (#3728)
- Change verbose logging to exactly mirror _Black_'s logic for source discovery (#3749)
### _Blackd_
-<!-- Changes to blackd -->
-
- The `blackd` argument parser now shows the default values for options in their help
text (#3712)
