+- Skip a problematic test on Python 3.12.0b1. The test fails on 3.12.0b1 due to
+  a bug in CPython, which will be fixed in 3.12.0b2. The
+  `typing_extensions` test suite now passes on 3.12.0b1.
+
 # Release 4.6.2 (May 25, 2023)
 
 - Fix use of `@deprecated` on classes with `__new__` but no `__init__`.
