* The HTML5 validator link will now be shown only to people with $db_show_debug permissions. Seriously, when it was cool for SMF to be XHTML-valid back in the 00's and boast about it, being HTML5-valid doesn't mean much these days, as HTML5 is so forgiving. It's just a geek thing, and will only be shown for debugging purposes if your HTML edits seem to break your pages. (Subs-Template.php, index.template.php, Stats.english.php, index.english.php)
