This is the first release of 2023, and following our 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)
Remove trailing newlines after code block open (#3035) (22.6.0)
Code cell separators #%% are now standardised to # %% (#2919) (22.3.0)
Remove unnecessary parentheses from except statements (#2939) (22.3.0)
Remove unnecessary parentheses from tuple unpacking in for loops (#2945) (22.3.0)
Avoid magic-trailing-comma in single-element subscripts (#2942) (22.3.0)
Fix a crash when a colon line is marked between # fmt: off and # fmt: on (#3439)
