+## 23.9.1
+
+Due to various issues, the previous release (23.9.0) did not include compiled mypyc
+wheels, which make Black significantly faster. These issues have now been fixed, and
+this release should come with compiled wheels once again.
+
+There will be no wheels for Python 3.12 due to a bug in mypyc. We will provide 3.12
+wheels in a future release as soon as the mypyc bug is fixed.
