The closest enemy tank to you will have its name appear floating above its head. Mouse control of the turret is implemented. Alt-Tab is fully supported, and returns you to your normal desktop resolution. Going bonkers past the edge of the map is temporarily fixed. Dedicated servers can be iconified.
Server log files are much smaller.
Plus lots of minor bug fixes and features. Controls are not yet configurable. Force Feedback is not yet implemented. Battle Match bots are still dumb. No mouse control yet.
