Version 0.8.8 was released 22 August 2010. Rob Savoye announced that Gnash should now work with all YouTube videos. Version 0.8.8 has GPU support, which pushed it ahead of the proprietary Adobe Flash Player in Linux, until Flash 10.2 came out with hardware acceleration built in. Gnash still suffers from high CPU usage. A Flashblock plugin can be installed by the user, turning on the Flash support on a case-by-case, as needed basis. YouTube video controls and full screen mode is functioning, although version 0.8.8 has a bug that can cause YouTube to display "Invalid parameters". Many popular Flash games do not work with Gnash 0.8.8.
