Updates the requirements on black to permit the latest version.

Release notes

23.1.0
Highlights
This is the first release of 2023, and following our stability policy, it comes with a number of improvements to our stable style, notably improvements to empty line handling and the removal of redundant parentheses in several contexts.

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)

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)

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)

Preview style

Format hex codes in unicode escape sequences in string literals (#2916)

Add parentheses around if-else expressions (#2278)

Improve performance on large expressions that contain many strings (#3467)

Fix a crash in preview style with assert + parenthesized string (#3415)

Fix crashes in preview style with walrus operators used in function return annotations and except clauses (#3423)

Fix a crash in preview advanced string processing where mixed implicitly concatenated 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)

Fix two crashes in preview style involving edge cases with docstrings (#3451)

Exclude string type annotations from improved string processing; fix crash when the return type annotation is stringified and spans across multiple lines (#3462)

Wrap multiple context managers in parentheses when targeting Python 3.9+ (#3489)

Fix several crashes in preview style with walrus operators used in with statements or tuples (#3473)

Fix an invalid quote escaping bug in f-string expressions where it produced invalid code. Implicitly concatenated f-strings with different quotes can now be merged or quote-normalized by changing the quotes used in expressions. (#3509)
