v23.3.0

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 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 (#​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)

v23.1.0

Compare Source

Highlights

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.

    • 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)

    • 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)

  • 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)

Compare Source

Highlights
