+  <para>Added tunnel parameters to the list of titles templates. This allows a customization
+  to determine the parent element of the list of titles. (For example, to format the table of contents

+  <para>When formatting a <tag>part</tag> with a <tag>partintro</tag> and a list of titles,
+  move the <tag>partintro</tag> before the list of titles. (This is technically backwards incompatible,
+  but it seems so obviously superior to the current behavior that I’m calling the current behavior

+  <para>Added a <parameter>inline-xlink-href</parameter> parameter to control whether or not
+  XLink href attributes are printed after the link in the paged media stylesheets;
+  fixed <link xlink:href="https://github.com/docbook/xslTNG/issues/404">#404</link>.
+  Previously, this was handled in two different ways: for simple
+  links, the links where always printed; for extended links, the text
+  were actually added by CSS. Now they’re both controlled by the
+  parameter and CSS is no longer involved.
