The Recently released FlashPlayer for the Nokia N9 has been updated to version 4.0.0-73.1. There is No changelog at the moment so I'm not sure exactly whats the benefit but newer is better, Isn't it ?
Update: This is only compatibility with PR1.0/1.1 releases fix. Now it is installable on older PR versions (previous one was installable only over PR1.2)
