This is (probably) a benign change, but a change non-the-less. Where we've previously replaced quotes with quot character entities, we don't anymore. I have yet to find a place in the docs where this causes a real issue, however.

E.g. in qtdoc/licenses-used-in-qt.html

-<tr class="even topAlign"><td class="tblName"><p><a href="qtmain.html">The qtmain Library</a></p></td><td class="tblDescr"><p>Commercial and BSD 3-clause "New" or "Revised" License.</p></td></tr>
+<tr class="odd topAlign"><td class="tblName"><p><a href="qtopenglextensions.html">The QtOpenGLExtensions Library</a></p></td><td class="tblDescr"><p>Commercial and BSD 3-clause "New" or "Revised" License</p></td></tr>
