### _Black_
+- Improve error message for invalid regular expression (#2678)
+- Improve error message when parsing fails during AST safety check by embedding the
+ underlying SyntaxError (#2693)
+- Fix mapping cases that contain as-expressions, like `case {"key": 1 | 2 as password}`
+ (#2686)
+- No longer color diff headers white as it's unreadable in light themed terminals
+ (#2691)
+
+## 21.12b0
+
+### _Black_
+
+- Fix determination of f-string expression spans (#2654)
+- Fix bad formatting of error messages about EOF in multi-line statements (#2343)
+- Functions and classes in blocks now have more consistent surrounding spacing (#2472)
+- `from __future__ import annotations` statement now implies Python 3.7+ (#2690)
+
+#### Jupyter Notebook support
+
+- Cell magics are now only processed if they are known Python cell magics. Earlier, all
+ cell magics were tokenized, leading to possible indentation errors e.g. with
+ `%%writefile`. (#2630)
+- Fix assignment to environment variables in Jupyter Notebooks (#2642)
+
+#### Python 3.10 support
+
+- Point users to using `--target-version py310` if we detect 3.10-only syntax (#2668)
+- Fix `match` statements with open sequence subjects, like `match a, b:` or
+ `match a, *b:` (#2639) (#2659)
+- Fix `match`/`case` statements that contain `match`/`case` soft keywords multiple
+ times, like `match re.match()` (#2661)
+- Fix `case` statements with an inline body (#2665)
+- Fix styling of starred expressions inside `match` subject (#2667)
+- Fix parser error location on invalid syntax in a `match` statement (#2649)
+- Fix Python 3.10 support on platforms without ProcessPoolExecutor (#2631)
+- Improve parsing performance on code that uses `match` under `--target-version py310`
+ up to ~50% (#2670)
+
+### Packaging
+
+- Remove dependency on `regex` (#2644) (#2663)
