\n\n
\n- Deprecate
\n--experimental-string-processingand move the functionality under--preview(#2789)- For stubs, one blank line between class attributes and methods is now kept if there's at least one pre-existing blank line (#2736)
\n- Black now normalizes string prefix order (#2297)
\n- Remove spaces around power operators if both operands are simple (#2726)
\n- Work around bug that causes unstable formatting in some cases in the presence of the magic trailing comma (#2807)

\n- Fix mapping cases that contain as-expressions, like
\ncase {"key": 1 | 2 as password}(#2686)- Fix cases that contain multiple top-level as-expressions, like
\ncase 1 as a, 2 as b(#2716)- Fix call patterns that contain as-expressions with keyword arguments, like
\ncase Foo(bar=baz as quux)(#2749)- Tuple unpacking on
\nreturnandyieldconstructs now implies 3.8+ (#2700)- Unparenthesized tuples on annotated assignments (e.g
\nvalues: Tuple[int, ...] = 1, 2, 3) now implies 3.8+ (#2708)- Fix handling of standalone
\nmatch()orcase()when there is a trailing newline or a comment inside of the parentheses. (#2760)- \n
from __future__ import annotationsstatement now implies Python 3.7+ (#2690)Performance

\n- Speed-up the new backtracking parser about 4X in general (enabled when
\n--target-versionis set to 3.10 and higher). (#2728)- Black is now compiled with mypyc for an overall 2x speed-up. 64-bit Windows, MacOS, and Linux (not including musl) are supported. (#1009, #2431)
\nConfiguration
\n\n
\n- Do not accept bare carriage return line endings in pyproject.toml (#2408)
\n- Add configuration option (
\npython-cell-magics) to format cells with custom magics in Jupyter Notebooks (#2744)- Allow setting custom cache directory on all platforms with environment variable
\nBLACK_CACHE_DIR(#2739).- Enable Python 3.10+ by default, without any extra need to specify -
\n-target-version=py310. (#2758)- Make passing
\nSRCor--codemandatory and mutually exclusive (#2804)Output
\n\n
\n- Improve error message for invalid regular expression (#2678)
\n- Improve error message when parsing fails during AST safety check by embedding the underlying SyntaxError (#2693)
\n- No longer color diff headers white as it's unreadable in light themed terminals (#2691)
\n- Text coloring added in the final statistics (#2712)
\n- Verbose mode also now describes how a project root was discovered and which paths will be formatted. (#2526)
