- Clang now diagnoses unexpected tokens after a
``#pragma clang|GCC diagnostic push|pop`` directive.
(`#13920: <https://github.com/llvm/llvm-project/issues/13920>`_)
+- Clang now does not try to analyze cast validity on variables with dependent alignment (`#63007: <https://github.com/llvm/llvm-project/issues/63007>`_).
