Dogfight 4.4.19 should be making its way through the google servers right now (and Apple during the week).

It has some major changes so although it's not mandatory at the moment, it will be enforced soon.
- It will use the new servers. These new servers should drastically reduce lag and disconnections! They are empty right now, so get the new release and enjoy the speed!!!
- Fixes many crashes on many Android phones. Samsung phones specifically.
- Fixes the glitch with the carriers that all of the sudden people were gone during the game.
- Added immunity for everyone, independent of rank. Lower ranks will have longer immunity time. Higher ranks will have shorter immunity time. This is to stop as much as possible the crazy camping going on by some that won't even allow people to take off.
- Reduced download size by 25%, so the update should get onto your phone faster!
- Improved performance by 50%, which means you should see the planes moving faster and smoother
- Many many more small fixes.
