+<h3 id="deprecated-headers">Deprecated headers</h3>
+<p>
+Some C++ Standard Library headers now produce deprecation warnings when
+included. The warnings suggest how to adjust the code to avoid the warning,
+for example all uses of <code>&lt;cstdbool&gt;</code> and
+<code>&lt;cstdalign&gt;</code> can simply be removed,
+because they serve no purpose and are unnecessary in C++ programs.
+Most uses of <code>&lt;ccomplex&gt;</code> can be adjusted to use
+<code>&lt;complex&gt;</code> instead, and uses of <code>&lt;ctgmath&gt;</code>
+can use <code>&lt;cmath&gt;</code> and/or <code>&lt;complex&gt;</code>.
