+#### 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 Python 3.10 support on platforms without ProcessPoolExecutor (#2631)
-- Reduce usage of the `regex` dependency (#2644)
+- 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 assignment to environment variables in Jupyter Notebooks (#2642)
-- Add `flake8-simplify` and `flake8-comprehensions` plugins (#2653)
-- Fix determination of f-string expression spans (#2654)
+- Fix styling of starred expressions inside `match` subject (#2667)
- Fix parser error location on invalid syntax in a `match` statement (#2649)
-- Functions and classes in blocks now have more consistent surrounding spacing (#2472)
+- 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)
