Compare Source

Highlights

This release fixes a security issue in Black's bundled GitHub Action. Repositories that
use the action are encouraged to update to the latest version of Black immediately. This
update is received automatically when using psf/black@stable, and is independent of
the version of Black installed by the action.

When the GitHub Action reads version specifiers from tool.black.required-version, it
now only accepts released versions of Black, as it already did for black requirements
in dependency lists. Other values, such as URL references, are now rejected. This issue
has been registered as GHSA-cg8m-r9f2-5wm2; a CVE identifier is pending.

Stable style

Fix a long Jupyter notebook assignment magic (for example x = !ls -la) being wrapped
in parentheses, which IPython can no longer run; such cells are now left unchanged
(#5481)
Keep repeated lines outside the selected --line-ranges unchanged (#5436)
Fix --line-ranges formatting lines that follow a statement when formatting joins or
re-indents that statement (#5484)
Fix --line-ranges crashing with an internal error when an unselected statement has a
# fmt: skip comment on the last line before a closing bracket (#5477)
Prevent moving an encoding declaration (for example # -*- coding: latin-1 -*-) onto
the first two lines of a file (#5487)
Fix adding an extra trailing blank line inside a multi-line module docstring when its
last line is near the line length limit (#5494)
Keep the parentheses around a walrus that is the only item in a set (for example
{(x := f())}) when targeting Python 3.9 or older, since Python 3.8 and 3.9.0 can't
parse it without them (#5502)

Preview style

Do not split short expressions on delimiters (such as binary operators, comparisons,
or comprehensions) inside brackets when preceded by a standalone comment (#5455)
Fix the unstable string_processing feature removing backslash-newline sequences from
raw strings, which changed their value (#5482)
Avoid adding unnecessary parentheses around unbreakable right-hand side expressions in
assignments (such as annotated assignments or subscript targets) (#5473)
Parenthesize expressions with parameter comments when they exceed the line length
under --preview (#5442)
Fix wrap_long_dict_values_in_parens dropping the parentheses around a right-hand
side that contains a dictionary, leaving a line over the length limit (#5492)
Fix the unstable string_processing feature adding a space after * or ** in a PEP
695 type parameter (* Ts = ...) when it splits a string in the parameter's default
(#5504)
Avoid unnecessary line splits of trailers (such as indexing/subscripts) when an
earlier bracket split exceeds the line length only due to a trailing comment (#5498)

Configuration

Add --cache-dir to configure the cache directory from the command line (#5433)
Don't cache a file as formatted after formatting or checking it with --line-ranges,
which made a later full black --check pass and black skip the unformatted lines
(#5476)
Respect a .gitignore that starts with a UTF-8 byte order mark. The mark became part
of the first pattern, so that pattern never matched and Black formatted files that git
ignores (#5497)

Performance

Avoid quadratic runtime when splitting very long lines with many trailing bracket
pairs (such as consecutive subscripts) (#5475)

Integrations

Fix the GitHub Action crashing on dependency-group includes when use_pyproject is
enabled (#5479)
When the GitHub Action reads version specifiers from tool.black.required-version, it
now only accepts released versions of Black, as it already did for black
requirements in dependency lists. Other values, such as URL references, are now
rejected. (#5510)
