+	    The compiler optimizes away building of terms that are
+	    never actually used. As a result, the compiler in OTP 18
+	    may produce more warnings for terms that are built but
+	    not used than the compiler in OTP 17.</p>

+	    The compiler now properly reports unknown parse
+	    transforms. That is, <c>undef</c> exceptions coming from
+	    the parse transform itself is reported differently from
+	    the absence of the parse transform.</p>

+	    <c>is_literal/1</c>, <c>is_literal_list/1</c>, and
+	    <c>literal_value</c>. Use the appropriate functions in
+	    the <c>cerl</c> module instead.</p>
