I've never undestood exactly if these changes are made to actually improve the site, or to make use of external scripts harder (they generally skip advertises...)
Are you talking about the 60p update? Many users have for a long time requested "real" support for 60fps video support (mostly let's players probably).
As fas as I know IE also supports it but not other browsers no matter system like Firefox or Maxthon etc :/
Also thanks, as soon as the Torrent link is there I will take it and seed on my server on my gigabit line
