We just received a stoker this week. The firmware version shows it is 2.6.0.193. When I go to the Kaytat site it looks like the latest non-beta version is Version 2.1.321 (June 23, 2009). For the beta versions list on the site the most recent is Version 2.6.0.249. This looks closer to the naming conventions of what came installed. Can somebody explain this for me? Also could somebody explain the relationship between Rock's and Kaytat Software? Is it recomended to upgrade the firmware at Kaytat? Thanks - John
