title: Which versions of IE support PNG favicons?
body: <p><a href="https://stackoverflow.com/questions/1344122/favicon-png-vs-favicon-ico-why-should-i-use-pngs-instead-of-icos"><strong>In this old StackOverflow post</strong></a>, it was said that only IE6 had issues with PNG favicons, <a href="http://channel9.msdn.com/Forums/TechOff/246218-PNG-Favicons-in-IE7-with-fallback-to-ICO-Favicon-in-pre-IE7" rel="nofollow noreferrer"><strong>but on channel9</strong></a>, it said that IE7 also does not support PNG favicons either. </p>
  
  <p>But, unfortunately, the channel9 link has been deleted - so does anyone know the official/tested information that states which version of IE started to support PNG favicons?</p>
