Created by: dependabot[bot]

Bumps black from 21.12b0 to 22.1.0.

Release notes

Sourced from black's releases.

22.1.0

At long last, Black is no longer a beta product! This is the first non-beta release and the first release covered by our new stability policy.

Highlights

• Remove Python 2 support (#2740)
• Introduce the --preview flag (#2752)

Style

• Deprecate --experimental-string-processing and 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)
• Black now normalizes string prefix order (#2297)
• Remove spaces around power operators if both operands are simple (#2726)
• Work around bug that causes unstable formatting in some cases in the presence of the magic trailing comma (#2807)
• Use parentheses for attribute access on decimal float and int literals (#2799)
• Don't add whitespace for attribute access on hexadecimal, binary, octal, and complex literals (#2799)
• Treat blank lines in stubs the same inside top-level if statements (#2820)
• Fix unstable formatting with semicolons and arithmetic expressions (#2817)
• Fix unstable formatting around magic trailing comma (#2572)

Parser

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

Performance

• Speed-up the new backtracking parser about 4X in general (enabled when --target-version is 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)

Configuration

• Do not accept bare carriage return line endings in pyproject.toml (#2408)
• Add configuration option (python-cell-magics) to format cells with custom magics in Jupyter Notebooks (#2744)
• Allow setting custom cache directory on all platforms with environment variable BLACK_CACHE_DIR (#2739).
• Enable Python 3.10+ by default, without any extra need to specify --target-version=py310. (#2758)
• Make passing SRC or --code mandatory and mutually exclusive (#2804)

Output

• Improve error message for invalid regular expression (#2678)
• Improve error message when parsing fails during AST safety check by embedding the underlying SyntaxError (#2693)
• No longer color diff headers white as it's unreadable in light themed terminals (#2691)
• Text coloring added in the final statistics (#2712)
• Verbose mode also now describes how a project root was discovered and which paths will be formatted. (#2526)

Packaging

• All upper version bounds on dependencies have been removed (#2718)
• typing-extensions is no longer a required dependency in Python 3.10+ (#2772)
• Set click lower bound to 8.0.0 as Black crashes on 7.1.2 (#2791)
