Opera 8.50 is out now out and it is no longer Ad Banner supported and has no Google Text Ads.  Instead it has switched to a Pay for Premium Support profit model.  It has fixed many of the minor bugs in the browser that have cropped up in the transition for new upcomming features like a built in BitTorrent Client and Rumoured extended Plugin Support.
