+- Format hex code in unicode escape sequences in string literals (#2916)
+- Add parentheses around `if`-`else` expressions (#2278)
+- Improve the performance on large expressions that contain many strings (#3467)
+- Fix a crash in preview style with assert + parenthesized string (#3415)
+- Fix crashes in preview style with walrus operators used in function return annotations
+ and except clauses (#3423)
+- Fix a crash in preview advanced string processing where mixed implicitly concatenated
+ regular and f-strings start with an empty span (#3463)
+- Fix a crash in preview advanced string processing where a standalone comment is placed
+ before a dict's value (#3469)
+- Fix an issue where extra empty lines are added when a decorator has `# fmt: skip`
+ applied or there is a standalone comment between decorators (#3470)
+- Do not put the closing quotes in a docstring on a separate line, even if the line is
+ too long (#3430)
+- Long values in dict literals are now wrapped in parentheses; correspondingly
+ unnecessary parentheses around short values in dict literals are now removed; long
+ string lambda values are now wrapped in parentheses (#3440)
+- Fix two crashes in preview style involving edge cases with docstrings (#3451)
+- Exclude string type annotations from improved string processing; fix crash when the
+ return type annotation is stringified and spans across multiple lines (#3462)
+- Wrap multiple context managers in parentheses when targeting Python 3.9+ (#3489)
+- Fix several crashes in preview style with walrus operators used in `with` statements
+ or tuples (#3473)
+- Fix an invalid quote escaping bug in f-string expressions where it produced invalid
+ code. Implicitly concatenated f-strings with different quotes can now be merged or
+ quote-normalized by changing the quotes used in expressions. (#3509)
