add to tag whitelist in the sanitizer.php the new & harmless HTML5 tags. for example <aside> <footer> <audio> <video> etc
<audio> and <video> make no sense as they can't have wiki-valid values from within an article afaik. Neither do <aside> and <footer> as they are layout elements which should never appear inside the content part of a page (eg. <article>).
