We're closing in on our next release of Unity version 3.4.1. Before we release to the world, we would appreciate everyone checking that the web player auto-update works. Providing you have the current released WebPlayer (3.4.0f5) already installed, please test the player we've uploaded here: http://files.unity3d.com/chris/AutoUpdate/WebPlayer.html You should see this if the auto-update is successful: If the player on that page causes any problems, please tell us immediately via replying to this thread. Thanks very much! Unity Team.
