Bumps black from 25.12.0 to 26.1.0.

Release notes

Sourced from black's releases.

26.1.0

Highlights

Introduces the 2026 stable style (#4892), stabilizing the following changes:

  • always_one_newline_after_import: Always force one blank line after import statements, except when the line after the import is a comment or an import statement (#4489)
  • fix_fmt_skip_in_one_liners: Fix # fmt: skip behavior on one-liner declarations, such as def foo(): return "mock" # fmt: skip, where previously the declaration would have been incorrectly collapsed (#4800)
  • fix_module_docstring_detection: Fix module docstrings being treated as normal strings if preceded by comments (#4764)
  • fix_type_expansion_split: Fix type expansions split in generic functions (#4777)
  • multiline_string_handling: Make expressions involving multiline strings more compact (#1879)
  • normalize_cr_newlines: Add \r style newlines to the potential newlines to normalize file newlines both from and to (#4710)
  • remove_parens_around_except_types: Remove parentheses around multiple exception types in except and except* without as (#4720)
  • remove_parens_from_assignment_lhs: Remove unnecessary parentheses from the left-hand side of assignments while preserving magic trailing commas and intentional multiline formatting (#4865)
  • standardize_type_comments: Format type comments which have zero or more spaces between # and type: or between type: and value to # type: (value) (#4645)

The following change was not in any previous stable release:

  • Regenerated the _width_table.py and added tests for the Khmer language (#4253)

This release alo bumps pathspec to v1 and fixes inconsistencies with Git's .gitignore logic (#4958). Now, files will be ignored if a pattern matches them, even if the parent directory is directly unignored. For example, Black would previously format exclude/not_this/foo.py with this .gitignore:

exclude/
!exclude/not_this/

Now, exclude/not_this/foo.py will remain ignored. To ensure exclude/not_this/ and all of it's children are included in formatting (and in Git), use this .gitignore:

*/exclude/*
!*/exclude/not_this/

This new behavior matches Git. The leading */ are only necessary if you wish to ignore matching subdirectories (like the previous behavior did), and not just matching root

if the parent directory is directly unignored. For example, Black would
previously
format <code>exclude/not_this/foo.py</code> with this
<code>.gitignore</code>:</p>
<pre><code>exclude/
!exclude/not_this/
</code></pre>
<p>Now, <code>exclude/not_this/foo.py</code> will remain ignored. To
ensure <code>exclude/not_this/</code> and
all of it's children are included in formatting (and in Git), use this
<code>.gitignore</code>:</p>
<pre><code>*/exclude/*
!*/exclude/not_this/
</code></pre>
<p>This new behavior matches Git. The leading <code>*/</code> are only
necessary if you wish to ignore
matching subdirectories (like the previous behavior did), and not just
matching root</p>

<blockquote>
<h2>26.1.0</h2>
<h3>Highlights</h3>
<p>Introduces the 2026 stable style (<a
href="https://redirect.github.com/psf/black/issues/4892">#4892</a>),
stabilizing the following changes:</p>
<ul>
<li><code>always_one_newline_after_import</code>: Always force one blank
line after import
statements, except when the line after the import is a comment or an
import statement
(<a
href="https://redirect.github.com/psf/black/issues/4489">#4489</a>)</li>
<li><code>fix_fmt_skip_in_one_liners</code>: Fix <code># fmt:
skip</code> behavior on one-liner declarations,
such as <code>def foo(): return &quot;mock&quot; # fmt: skip</code>,
where previously the declaration would
have been incorrectly collapsed (<a
href="https://redirect.github.com/psf/black/issues/4800">#4800</a>)</li>
<li><code>fix_module_docstring_detection</code>: Fix module docstrings
being treated as normal
strings if preceded by comments (<a
href="https://redirect.github.com/psf/black/issues/4764">#4764</a>)</li>
<li><code>fix_type_expansion_split</code>: Fix type expansions split in
generic functions (<a
href="https://redirect.github.com/psf/black/issues/4777">#4777</a>)</li>
<li><code>multiline_string_handling</code>: Make expressions involving
multiline strings more compact
(<a
href="https://redirect.github.com/psf/black/issues/1879">#1879</a>)</li>
<li><code>normalize_cr_newlines</code>: Add <code>\r</code> style
newlines to the potential newlines to
normalize file newlines both from and to (<a
href="https://redirect.github.com/psf/black/issues/4710">#4710</a>)</li>
<li><code>remove_parens_around_except_types</code>: Remove parentheses
around multiple exception
types in <code>except</code> and <code>except*</code> without
<code>as</code> (<a
href="https://redirect.github.com/psf/black/issues/4720">#4720</a>)</li>
<li><code>remove_parens_from_assignment_lhs</code>: Remove unnecessary
parentheses from the left-hand
side of assignments while preserving magic trailing commas and
intentional multiline
formatting (<a
href="https://redirect.github.com/psf/black/issues/4865">#4865</a>)</li>
<li><code>standardize_type_comments</code>: Format type comments which
have zero or more spaces
between <code>#</code> and <code>type:</code> or between
<code>type:</code> and value to <code># type: (value)</code> (<a
href="https://redirect.github.com/psf/black/issues/4645">#4645</a>)</li>
</ul>
<p>The following change was not in any previous stable release:</p>
<ul>
<li>Regenerated the <code>_width_table.py</code> and added tests for the
Khmer language (<a
href="https://redirect.github.com/psf/black/issues/4253">#4253</a>)</li>
</ul>
<p>This release alo bumps <code>pathspec</code> to v1 and fixes
inconsistencies with Git's
<code>.gitignore</code> logic (<a
href="https://redirect.github.com/psf/black/issues/4958">#4958</a>).
Now, files will be ignored if a pattern matches them, even
if the parent directory is directly unignored. For example, Black would
previously
format <code>exclude/not_this/foo.py</code> with this
<code>.gitignore</code>:</p>
<pre><code>exclude/
!exclude/not_this/
</code></pre>
<p>Now, <code>exclude/not_this/foo.py</code> will remain ignored. To
ensure <code>exclude/not_this/</code> and
all of it's children are included in formatting (and in Git), use this
<code>.gitignore</code>:</p>
<pre><code>*/exclude/*
!*/exclude/not_this/
</code></pre>
<p>This new behavior matches Git. The leading <code>*/</code> are only
necessary if you wish to ignore</p>
