Release Notes
psf/black (black)
v24.1.1
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)
v24.1.0
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. 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)
v23.12.1
Packaging
- Fixed a bug that included dependencies from the
d
extra by default (#4108)
v23.12.0
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.
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)
- Additional cases of immediately nested tuples, lists, and dictionaries are now 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)
Configuration
-
--line-ranges
now skips Black's internal stability check in--safe
mode. This avoids a crash on rare inputs that have many unformatted same-content lines. (#4034)
Packaging
- Upgrade to mypy 1.7.1 (#4049) (#4069)
- Faster compiled wheels are now available for CPython 3.12 (#4070)

- Fix standalone comments inside complex blocks crashing Black (#4016)
- Fix crash on formatting code like
await (a ** b)
(#3994) - No longer treat leading f-strings as docstrings. This matches Python's behaviour and fixes a crash (#4019)
Preview style

- 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 oncase
blocks (#4024) - Keep requiring two empty lines between module-level docstring and first function or class definition (#4028)

--include
(#3976)
Performance

v23.9.1
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)

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
