This release provides a preview of Black's 2023 stable style. Black's default formatting style includes the following 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)
Please try it out and give feedback here: psf/black#3407
A stable 23.1.0 release will follow in January 2023.
