+- Update to release 11.0
+  * Correctly forbid functions returning struct in K&R C.
+  * Support digraphs before C95 and trigraphs in K&R C.
+  * Optional () for destructor.
+  * C++20's nested inline namespaces are now supported
+  * In-class default, delete, and noexcept constructors are now
+    accepted.
+  * A raw string literal like R"abc(X)ab)abc" was previously not
+    parsed correctly.
+  * An array of reference (or rvalue reference) is now correctly
+    flagged as an error.
