- Black is now officially tested with Python 3.13 and provides Python 3.13
mypyc-compiled wheels. (4436) (4449)
- Black will issue an error when used with Python 3.12.5, due to an upstream memory
safety issue in Python 3.12.5 that can cause Black's AST safety checks to fail. Please

fn(*args: *tuple[*Ts, T]) -> None: pass`) (4440)

Caching

- Fix bug where the cache was shared between runs with and without `--unstable` (4466)

Packaging

- Upgrade version of mypyc used to 1.12 beta (4450) (4449)
- `blackd` now requires a newer version of aiohttp. (4451)

Output

- Added Python target version information on parse error (4378)
- Add information about Black version to internal error messages (4457)

24.8.0

Stable style

- Fix crash when ` fmt: off` is used before a closing parenthesis or bracket. (4363)

Packaging

- Packaging metadata updated: docs are explictly linked, the issue tracker is now also
linked. This improves the PyPI listing for Black. (4345)

_Blackd_

- Fix blackd (and all extras installs) for docker container (4357)

24.4.2

This is a bugfix release to fix two regressions in the new f-string parser introduced in
24.4.1.

Parser

- Fix regression where certain complex f-strings failed to parse (4332)

Performance

- Fix bad performance on certain complex string literals (4331)

24.4.1

Highlights

- Add support for the new Python 3.12 f-string syntax introduced by PEP 701 (3822)

Stable style

- Fix crash involving indented dummy functions containing newlines (4318)

Parser

- Add support for type parameter defaults, a new syntactic feature added to Python 3.13
by PEP 696 (4327)

Integrations

- Github Action now works even when `git archive` is skipped (4313)

24.4.0

Stable style

- Fix unwanted crashes caused by AST equivalency check (4290)

- `if` guards in `case` blocks are now wrapped in parentheses when the line is too long.
(4269)
- Stop moving multiline strings to a new line unless inside brackets (4289)

Integrations

- Add a new option `use_pyproject` to the GitHub Action `psf/black`. This will read the
Black version from `pyproject.toml`. (4294)

24.3.0

Highlights

This release is a milestone: it fixes Black's first CVE security vulnerability. If you
run Black on untrusted input, or if you habitually put thousands of leading tab
characters in your docstrings, you are strongly encouraged to upgrade immediately to fix
[CVE-2024-21503](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2024-21503).

This release also fixes a bug in Black's AST safety check that allowed Black to make
incorrect changes to certain f-strings that are valid in Python 3.12 and higher.

Stable style

- Don't move comments along with delimiters, which could cause crashes (4248)
- Strengthen AST safety check to catch more unsafe changes to strings. Previous versions
of Black would incorrectly format the contents of certain unusual f-strings containing
nested strings with the same quote type. Now, Black will crash on such strings until
support for the new f-string syntax is implemented. (4270)
- Fix a bug where line-ranges exceeding the last code line would not work as expected
(4273)

Performance

- Fix catastrophic performance on docstrings that contain large numbers of leading tab
characters. This fixes
[CVE-2024-21503](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2024-21503).
(4278)

Documentation

- Note what happens when `--check` is used with `--quiet` (4236)

24.2.0

Stable style

- Fixed a bug where comments where mistakenly removed along with redundant parentheses
(4218)

Preview style

- Move the `hug_parens_with_braces_and_square_brackets` feature to the unstable style
due to an outstanding crash and proposed formatting tweaks (4198)
- Fixed a bug where base expressions caused inconsistent formatting of \*\* in tenary
expression (4154)
- Checking for newline before adding one on docstring that is almost at the line limit
(4185)
- Remove redundant parentheses in `case` statement `if` guards (4214).

Configuration

- Fix issue where _Black_ would ignore input files in the presence of symlinks (4222)
- _Black_ now ignores `pyproject.toml` that is missing a `tool.black` section when
discovering project root and configuration. Since _Black_ continues to use version
control as an indicator of project root, this is expected to primarily change behavior
for users in a monorepo setup (desirably). If you wish to preserve previous behavior,
simply add an empty `[tool.black]` to the previously discovered `pyproject.toml`
(4204)

Output

- Black will swallow any `SyntaxWarning`s or `DeprecationWarning`s produced by the `ast`
module when performing equivalence checks (4189)

Integrations

- Add a JSONSchema and provide a validate-pyproject entry-point (4181)

24.1.1

Bugfix release to fix a bug that made Black unusable on certain file systems with strict
limits on path length.

Preview style

- Consistently add trailing comma on typed parameters (4164)

Configuration

- Shorten the length of the name of the cache file to fix crashes on file systems that
do not support long paths (4176)

24.1.0

Highlights

This release introduces the new 2024 stable style (4106), stabilizing the following
changes:

- Add parentheses around `if`-`else` expressions (2278)
- Dummy class and function implementations consisting only of `...` are formatted more
compactly (3796)
- If an assignment statement is too long, we now prefer splitting on the right-hand side
(3368)
- Hex codes in Unicode escape sequences are now standardized to lowercase (2916)
- Allow empty first lines at the beginning of most blocks (3967, 4061)
- Add parentheses around long type annotations (3899)
- Enforce newline after module docstrings (3932, 4028)
- Fix incorrect magic trailing comma handling in return types (3916)
- Remove blank lines before class docstrings (3692)
- Wrap multiple context managers in parentheses if combined in a single `with` statement
(3489)
- Fix bug in line length calculations for power operations (3942)
- Add trailing commas to collection literals even if there's a comment after the last
entry (3393)
- When using `--skip-magic-trailing-comma` or `-C`, trailing commas are stripped from
subscript expressions with more than 1 element (3209)
- Add extra blank lines in stubs in a few cases (3564, 3862)
- Accept raw strings as docstrings (3947)
- Split long lines in case blocks (4024)
- Stop removing spaces from walrus operators within subscripts (3823)
- Fix incorrect formatting of certain async statements (3609)
- Allow combining ` fmt: skip` with other comments (3959)

There are already a few improvements in the `--preview` style, which are slated for the
2025 stable style. Try them out and
[share your feedback](https://github.com/psf/black/issues). In the past, the preview
style has included some features that we were not able to stabilize. This year, we're
adding a separate `--unstable` style for features with known problems. Now, the
`--preview` style only includes features that we actually expect to make it into next
year's stable style.

Stable style

Several bug fixes were made in features that are moved to the stable style in this
release:

- Fix comment handling when parenthesising conditional expressions (4134)
- Fix bug where spaces were not added around parenthesized walruses in subscripts,
unlike other binary operators (4109)
- Remove empty lines before docstrings in async functions (4132)
- Address a missing case in the change to allow empty lines at the beginning of all
blocks, except immediately before a docstring (4130)
- For stubs, fix logic to enforce empty line after nested classes with bodies (4141)

Preview style

- Add `--unstable` style, covering preview features that have known problems that would
block them from going into the stable style. Also add the `--enable-unstable-feature`
flag; for example, use
`--enable-unstable-feature hug_parens_with_braces_and_square_brackets` to apply this
preview feature throughout 2024, even if a later Black release downgrades the feature
to unstable (4096)
- Format module docstrings the same as class and function docstrings (4095)
- Fix crash when using a walrus in a dictionary (4155)
- Fix unnecessary parentheses when wrapping long dicts (4135)
- Stop normalizing spaces before ` fmt: skip` comments (4146)

Configuration

- Print warning when configuration in `pyproject.toml` contains an invalid key (4165)
- Fix symlink handling, properly ignoring symlinks that point outside of root (4161)
- Fix cache mtime logic that resulted in false positive cache hits (4128)
- Remove the long-deprecated `--experimental-string-processing` flag. This feature can
currently be enabled with `--preview --enable-unstable-feature string_processing`.
(4096)

Integrations

- Revert the change to run Black's pre-commit integration only on specific git hooks
(3940) for better compatibility with older versions of pre-commit (4137)

23.12.1

Packaging

- Fixed a bug that included dependencies from the `d` extra by default (4108)

23.12.0

Highlights

It's almost 2024, which means it's time for a new edition of _Black_'s stable style!
Together with this release, we'll put out an alpha release 24.1a1 showcasing the draft
2024 stable style, which we'll finalize in the January release. Please try it out and
[share your feedback](https://github.com/psf/black/issues/4042).

This release (23.12.0) will still produce the 2023 style. Most but not all of the
changes in `--preview` mode will be in the 2024 stable style.

Stable style

- Fix bug where ` fmt: off` automatically dedents when used with the `--line-ranges`
option, even when it is not within the specified line range. (4084)
- Fix feature detection for parenthesized context managers (4104)

Preview style

- Prefer more equal signs before a break when splitting chained assignments (4010)
- Standalone form feed characters at the module level are no longer removed (4021)

indented less (4012)
- Allow empty lines at the beginning of all blocks, except immediately before a
docstring (4060)
- Fix crash in preview mode when using a short `--line-length` (4086)
- Keep suites consisting of only an ellipsis on their own lines if they are not
functions or class definitions (4066) (4103)

less (3964)
- Multiline unpacked dicts and lists as the sole argument to a function are now also
indented less (3992)
- In f-string debug expressions, quote types that are visible in the final string are
now preserved (4005)
- Fix a bug where long `case` blocks were not split into multiple lines. Also enable
general trailing comma rules on `case` blocks (4024)
- Keep requiring two empty lines between module-level docstring and first function or
class definition (4028)
- Add support for single-line format skip with other comments on the same line (3959)

Configuration

- Consistently apply force exclusion logic before resolving symlinks (4015)
- Fix a bug in the matching of absolute path names in `--include` (3976)

Performance

- Fix mypyc builds on arm64 on macOS (4017)

Integrations

code (3933)
- Black will more consistently print stacktraces on internal errors in verbose mode
(3938)

Integrations

- The action output displayed in the job summary is now wrapped in Markdown (3914)

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)

_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)

- Remove patching of Click that mitigated errors on Python 3.6 with `LANG=C` (3768)

Parser

- Add support for the new PEP 695 syntax in Python 3.12 (3703)

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

- 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_

- The `blackd` argument parser now shows the default values for options in their help

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

- 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

- 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

- 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)
- When using `--skip-magic-trailing-comma` or `-C`, trailing commas are stripped from
 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)
- Fix a string merging/split issue when a comment is present in the middle of
 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)
- Parentheses around return annotations are now managed (2990) (22.6.0)
- Remove unnecessary parentheses around awaited objects (2991) (22.6.0)
- Remove unnecessary parentheses in `with` statements (2926) (22.6.0)

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

(3380)
- This also fixes some crashes while using compiled Black with a debug build of
 CPython
- Drop specific support for the `tomli` requirement on 3.11 alpha releases, working
around a bug that would cause the requirement not to be installed on any non-final

3.7 due to standard library limitations. (2874)

Performance

- Reduce Black's startup time when formatting a single file by 15-30% (3211)

File-Level Changes

Change	Details	Files
Updated black from 20.8b1 to 25.1.0.	Introduced the new 2025 stable style. Normalized casing of Unicode escape characters in strings to lowercase. Fixed inconsistencies in whether certain strings are detected as docstrings. Consistently added trailing commas to typed function parameters. Removed redundant parentheses in if guards for case blocks. Added parentheses to if clauses in case blocks when the line is too long. Whitespace before fmt: skip comments is no longer normalized. Fixed line length computation for certain expressions that involve the power operator. Checked if there is a newline before the terminating quotes of a docstring. Fixed type annotation spacing between * and more complex type variable tuple. Removed parentheses around sole list items. Generic function definitions are now formatted more elegantly. Fixed formatting cells in IPython notebooks with magic methods and starting or trailing empty lines. Fixed crash when formatting with statements containing tuple generators/unpacking. Fixed/removed string merging changing f-string quotes on f-strings with internal quotes. Collapsed multiple empty lines after an import into one. Prevented string_processing and wrap_long_dict_values_in_parens from removing parentheses around long dictionary values. Moved wrap_long_dict_values_in_parens from the unstable to preview style. Stored license identifier inside the License-Expression metadata field. Speed up the is_fstring_start function in Black's tokenizer. If using stdin with --stdin-filename set to a force excluded path, stdin won't be formatted.	requirements.txt
Updated pylint from 2.6.0 to 3.3.4.	Dropped support for Python 3.7, 3.8, and for pylint below 3.0. Added Django aliases for ranges to support psycopg 2 and 3. Support for Python 3.12 datetime. Fixed location of installed LICENSE file. Fixed ForeignKeyStringChecker referencing linter config incorrectly. CI now tests against Django 5.1	requirements.txt
Updated flake8 from 3.8.4 to 7.1.2.		requirements.txt
Updated Cython from 0.29.21 to 3.0.12.	Release 3.0.11 introduced some incorrect noexcept warnings. Conditional assignments to variables using the walrus operator could crash. Dict assignments to struct members with reserved C names could generate invalid C code. Fused ctuples with the same entry types but different sizes could fail to compile. In Py3, pyximport was not searching sys.path when looking for importable source files. Using & 0 on integers produced with int.from_bytes() could read invalid memory on Python 3.10. Modules could fail to compile in PyPy 3.11 due to missing CPython specific header files. Minor fix in C++ partial_sum() declaration.	requirements.txt
Updated alpaca-trade-api, google-cloud-logging, therapist, setuptools, wheel, twine, bandit, scipy, solana, pytest_asyncio, pytest, and finrashortdata.		requirements.txt
