-- Comments are no longer deleted when a line had spaces removed around power operators
- (#2874)
+- Fix a crash when a colon line is marked between `# fmt: off` and `# fmt: on` (#3439)
### Preview style
<!-- Changes that affect Black's preview style -->

+ regular and f-strings start with an empty span (#3463)
+- Fix a crash in preview advanced string processing where a standalone comment is placed
+ before a dict's value (#3469)
+- Fix an issue where extra empty lines are added when a decorator has `# fmt: skip`
+ applied or there is a standalone comment between decorators (#3470)
+- Do not put the closing quotes in a docstring on a separate line, even if the line is
+ too long (#3430)

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

-- Recommend using BlackConnect in IntelliJ IDEs (#3150)
+- Expand `vim-plug` installation instructions to offer more explicit options (#3468)
+
+## 22.12.0
+
+### Preview style
+
+<!-- Changes that affect Black's preview style -->
+
+- Enforce empty lines before classes and functions with sticky leading comments (#3302)
+- 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)
+- Implicitly concatenated strings used as function args are now wrapped inside
+ parentheses (#3307)
+- For assignment statements, prefer splitting the right hand side if the left hand side
+ fits on a single line (#3368)
+- Correctly handle trailing commas that are inside a line's leading non-nested parens
+ (#3370)
+
+### Configuration
+
+<!-- Changes to how Black can be configured -->
+
+- Fix incorrectly applied `.gitignore` rules by considering the `.gitignore` location
+ and the relative path to the target file (#3338)
+- Fix incorrectly ignoring `.gitignore` presence when more than one source directory is
+ specified (#3336)
+
+### Parser
+
+<!-- Changes to the parser or to version autodetection -->
+
+- Parsing support has been added for walruses inside generator expression that are
+ passed as function args (for example,
+ `any(match := my_re.match(text) for text in texts)`) (#3327).
### Integrations
<!-- For example, Docker, GitHub Actions, pre-commit, editors -->
-### Output
+- Vim plugin: Optionally allow using the system installation of Black via
+ `let g:black_use_virtualenv = 0`(#3309)
-<!-- Changes to Black's terminal output and error messages -->
+## 22.10.0
+
+### Highlights
+
+- Runtime support for Python 3.6 has been removed. Formatting 3.6 code will still be
+ supported until further notice.
+
+### Stable style
+
+- Fix a crash when `# fmt: on` is used on a different block level than `# fmt: off`
+ (#3281)
+
+### Preview style
+
+- Fix a crash when formatting some dicts with parenthesis-wrapped long string keys
+ (#3262)
+
+### Configuration
+
+- `.ipynb_checkpoints` directories are now excluded by default (#3293)
+- Add `--skip-source-first-line` / `-x` option to ignore the first line of source code
+ while formatting (#3299)
### Packaging
-<!-- Changes to how Black is packaged, such as dependency requirements -->
+- Executables made with PyInstaller will no longer crash when formatting several files
+ at once on macOS. Native x86-64 executables for macOS are available once again.
+ (#3275)
+- Hatchling is now used as the build backend. This will not have any effect for users
+ who install Black with its wheels from PyPI. (#3233)
+- Faster compiled wheels are now available for CPython 3.11 (#3276)
-### Parser
+### _Blackd_
-<!-- Changes to the parser or to version autodetection -->
+- Windows style (CRLF) newlines will be preserved (#3257).
+
+### Integrations
+
+- Vim plugin: add flag (`g:black_preview`) to enable/disable the preview style (#3246)
+- Update GitHub Action to support formatting of Jupyter Notebook files via a `jupyter`
+ option (#3282)
+- Update GitHub Action to support use of version specifiers (e.g. `<23`) for Black
+ version (#3265)
+
+## 22.8.0
+
+### Highlights
+
+- Python 3.11 is now supported, except for _blackd_ as aiohttp does not support 3.11 as
+ of publishing (#3234)
+- This is the last release that supports running _Black_ on Python 3.6 (formatting 3.6
+ code will continue to be supported until further notice)
+- Reword the stability policy to say that we may, in rare cases, make changes that
+ affect code that was not previously formatted by _Black_ (#3155)
+
+### Stable style
+
+- Fix an infinite loop when using `# fmt: on/off` in the middle of an expression or code
+ block (#3158)
+- Fix incorrect handling of `# fmt: skip` on colon (`:`) lines (#3148)
+- Comments are no longer deleted when a line had spaces removed around power operators
+ (#2874)
+
+### Preview style
+
+- Single-character closing docstring quotes are no longer moved to their own line as
+ this is invalid. This was a bug introduced in version 22.6.0. (#3166)
+- `--skip-string-normalization` / `-S` now prevents docstring prefixes from being
+ normalized as expected (#3168)
+- When using `--skip-magic-trailing-comma` or `-C`, trailing commas are stripped from
+ subscript expressions with more than 1 element (#3209)
+- Implicitly concatenated strings inside a list, set, or tuple are now wrapped inside
+ parentheses (#3162)
+- Fix a string merging/split issue when a comment is present in the middle of implicitly
+ concatenated strings on its own line (#3227)
+
+### _Blackd_
+
+- `blackd` now supports enabling the preview style via the `X-Preview` header (#3217)
+
+### Configuration
+
+- Black now uses the presence of debug f-strings to detect target version (#3215)
+- Fix misdetection of project root and verbose logging of sources in cases involving
+ `--stdin-filename` (#3216)
+- Immediate `.gitignore` files in source directories given on the command line are now
+ also respected, previously only `.gitignore` files in the project root and
+ automatically discovered directories were respected (#3237)
+
+### Documentation
+
+- Recommend using BlackConnect in IntelliJ IDEs (#3150)
+
+### Integrations
+
+- Vim plugin: prefix messages with `Black: ` so it's clear they come from Black (#3194)
+- Docker: changed to a /opt/venv installation + added to PATH to be available to
+ non-root users (#3202)
+
+### Output
+
+- Change from deprecated `asyncio.get_event_loop()` to create our event loop which
+ removes DeprecationWarning (#3164)
+- Remove logging from internal `blib2to3` library since it regularly emits error logs
+ about failed caching that can and should be ignored (#3193)
+
+### Parser
- Type comments are now included in the AST equivalence check consistently so accidental
deletion raises an error. Though type comments can't be tracked when running on PyPy
### Performance
-<!-- Changes that improve Black's performance. -->
+- Reduce Black's startup time when formatting a single file by 15-30% (#3211)
