+## 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](https://black.readthedocs.io/en/stable/the_black_code_style/index.html#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](https://github.com/mypyc/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` (#2791)
+
+### Integrations
+
+- Update GitHub action to support containerized runs (#2748)
+
+### Documentation
+
+- Change protocol in pip installation instructions to `https://` (#2761)
+- Change HTML theme to Furo primarily for its responsive design and mobile support
+ (#2793)
+- Deprecate the `black-primer` tool (#2809)
+- Document Python support policy (#2819)
