The HTML output contains raw <script> tags when they should be <script type="text/javascript">. This will have some effect on different browsers, and contribute to misinterpreted JavaScript bugs.
From release notes (trimmed): * The default output format is now HTML 5 instead of XHTML 1.0 Transitional. This can be disabled by setting $wgHtml5 = false;. Specific features enabled if HTML 5 is used: ** Unnecessary type="" attribute removed for CSS and JS.
