v23.3.0

Compare Source

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.

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.
