+  <li>The Address Sanitizer feature and Clang's
+  <tt>-fcatch-undefined-behavior</tt> option have been moved to a unified flag
+  set: <tt>-fsanitize</tt>. This flag can be used to enable the different
+  dynamic checking tools when building. For example,
+  <tt>-faddress-sanitizer</tt> is now <tt>-fsanitize=address</tt>, and
+  <tt>-fcatch-undefined-behavior</tt> is now <tt>-fsanitize=undefined</tt>.
+  With this release the set of checks available continues to grow, see the Clang
+  documentaion and specific sanitizer notes below for details.
